Do Dogs Smile?

We’ve all seen it at one point or another: a dog who appeared to be smiling. Lips pulled back, eyes and brow relaxed, maybe even tail wagging – of course that dog is smiling! Right?

The answer to whether dogs can smile or not depends on how we think about canine behavior – specifically the degree to which we project our human understanding of body language onto the behaviors of our dogs.

A well-accepted theory among dog behavior experts is that dogs smile because they know we humans love it. We see our dogs lounging on the rug with their mouths hanging open, lips pulled back, looking utterly satisfied with themselves, and we go ga-ga with praise and pets. Dogs probably also observe their humans smiling at them and among themselves; they know people smiles are inherently positive (at the very least, benign), and that they can communicate amicability by miming that behavior.

Given the way we understand dog cognition, the notion that the smiling dog has learned to smile from people – and does so primarily for people – makes a lot of sense. We can think of dogs smiling in the way we consider some dogs to speak words: we reinforce our dogs when they make any noise resembling a word and they continue to do it, but only we have assigned meanings for those words. The semantics of any vocalization our dogs make is lost to them, yet they will still project their voices in highly specific ways because they know it will elicit a positive response.

Is A Smiling Dog Really Smiling?

The Merriam-Webster English dictionary defines a smile (noun) as “a facial expression in which the eyes brighten and the corners of the mouth curve slightly upward and which expresses especially amusement, pleasure, approval, or sometimes scorn.” Human smiles can be involuntary, like when we experience a beautiful moment, or they can be entirely performative, like when we need a favor from someone we don’t like.

It’s safe to say that smiles are essential to the human body language vocabulary. We smile to manipulate other people as often and as naturally as we smile to connect with them. Why then shouldn’t dogs, who have spent the past fifteen millennia becoming masters of non-verbal communication with humans, be able to do the same?

Submissive Grins

There are many canine facial expressions that may look like smiles to us. Sometimes the dog is just panting, with lips pulled back and mouth wide open; this is just an effort to move as much cooling air down his throat as possible – it’s not smiling! Some snarls may even look like a smile to someone (such as a small child) who is unaware of accompanying signs of a dog’s uneasiness (such as growling, looking away, a stiff body, still and upright tail, etc.).

But the most common expression that is mistaken for a smile is what behaviorists call a submissive grin. Characterized by teeth that are bared in a comical way that shouldn’t be mistaken for aggression, accompanied by lowered body posture, squinted eyes, and an upturned neck, submissive grins are interpreted by most people as the dog expressing happiness. Also known as an appeasement grin, this doggy facial expression actually signals deference and a desire to show that he’s not a threat.

How to Train Your Dog to Smile

You can train your dog to “smile” on cue with some simple positive reinforcement. You would do this by “capturing” the behavior by using a consistent reward marker, such as the click of a clicker or the word “Yes!” every time your dog displays the smile, and immediately give her a reward. Then, begin using a cue at the times when you can reliably predict that she is about to offer the behavior, like when you first walk in the door from work. Say “Smile!” and when she displays the behavior, click and give her a treat!

Of course, having your dog’s smile on cue would not make it a genuine canine expression of happiness, but the love and attention your dog receives for performing smiles will make the behavior synonymous to happiness – and that is just as good.

Dog Ice Cream Treats

You scream, we scream, but do dogs scream for ice cream? It’s cute (and Instagrammable) to see a pair of puppy paws wrapped around a rainbow-sprinkled ice cream cone, but can dogs eat ice cream or should pups stick to specialty dog ice cream treats?

Ice cream, of course, contains milk. And just like humans, some dogs (not all) are lactose-intolerant. If you feed milk to a lactose-intolerant dog, he may experience diarrhea, painful gas, or vomiting. Of course, ice cream is a treat, not a diet staple, so start by giving your dog no more than a spoonful, and wait for a day to see if he has any negative response to the frozen dessert. As long as he does not, he should be able to enjoy a prudent amount as an occasional treat.
Milk isn’t the only issue when it comes to feeding your pup ice cream. Sugar is another primary concern, especially as sugar is sometimes accompanied by xylitol, an artificial sweetener that can be lethal to dogs. Xylitol is a sugar substitute often found in chewing gum, mints, certain brands of peanut butter, toothpastes, and sugar-free pudding, yogurt, and Jell-O; it can also turn up in ice cream, so be sure to read the ingredients list.

See “13 Household Items Toxic to Dogs” for more on xylitol and other common dangers to dogs.

Something else to take into consideration is the flavor of the ice cream you share with your dog. As many pet owners know, chocolate can be harmful to dogs, so choose other flavors.

Dog Ice Cream and Other Alternatives for Dogs

There are doggy-friendly alternatives to traditional ice cream made for humans. Frozen yogurt usually contains significantly less lactose than ice cream, making it a good alternative for dogs who show signs of being lactose-intolerant. Just be sure the one you choose is not saturated with sugar and sweeteners (also make sure it does not contain xylitol).

“Nice cream” is another good alternative. The vegan, homemade version of ice cream, “nice cream” is made by putting a frozen banana in a food processor along with the flavor of your choice.

Then there are the dog ice cream commercial products. There are two powdered dog ice cream “mixes” on the market (Pooch Creamery and Puppy Scoops); each requires that you add water, stir, freeze, and serve. FrostyPaws (Purina’s foray into doggie ice cream) is sold in some pet supply stores and grocery stores, but contains unnecessary additives like gelatin, soy flour, corn oil, salt, and maltodextrin and polydextrose (chemical sweeteners).

Often, going the homemade route is a better, healthier choice than commerical dog ice creams. If you’re looking to make your own dog ice cream at home with just a few, simple, healthful ingredients, the Humane Society offers a peanut butter pup-sicle recipe, or the tuna pops, PB&J smoothie pops, or frozen meatball recipes offered on Dog Treat Kitchen.

Best Ice Cream Flavors for Dogs

Flavors that are both non-toxic and yummy to dogs include: pumpkin, peanut butter, cinnamon, coconut, and banana. Carob chips are also a healthier alternative to chocolate chips and can be used not just to add as a decadent topping but to incorporate in the flavor as well (think peanut butter-carob ice cream).

Flavors to absolutely avoid include: chocolate, anything with raisins, chocolate-covered nuts, macadamia nuts, and anything that contains xylitol.

Frozen Dog Treats: How to Make Pupsicles for Your Dog

With temperatures heating up across the country, pupsicles are an easy and highly customizable treat that can entertain your dogs while keeping them cool and hydrated. Pupsicles don’t take the place of making sure your dog is drinking fresh water, but they are a fun way to add more hydration to your dog’s day. Here are a few easy popsicle recipes your dog is sure to enjoy.

Frozen Dog Treat Recipes

To make these frozen treats for your dog you will need a few ice cube trays. You can purchase variously sized silicone baking molds at craft and kitchen supply stores. These molds are inexpensive, easy to freeze, and a perfect way to make different sized treats.

Interactive– Frozen treats can be more than a tasty reward, they can actually be an enrichment toy for your dog. To make these giant interactive enriching popsicles, add items such as your dog’s favorite ball, toy rope, and other water-safe toys into large silicone freezable molds.  Then fill with water, put the mold onto a cookie sheet, and place in your freezer overnight. Remove the giant popsicle from the mold and give to your dog.  This interactive treat/toy combination will keep your dog busy eating their frozen treat and digging out the toys! Be warned; it’s also messy as it starts to melt, so give this jumbo pop  to your dog outside in the yard.

Broth Treats: If your dog needs extra enticement, use chicken, beef or vegetable broth instead of, or mixed with water. Just make sure the broth you use doesn’t contain salt. Freeze the broth in ice cube trays or other silicone containers overnight. You can use this base to spice up the next two recipes as well.

Veggie Treats – To give your dog’s popsicles an added crunch, consider adding small slices of healthy, low-calorie vegetables like carrots and cucumbers to the broth.. You can either fully submerge the vegetables or leave them sticking out to encourage your dog to discover the veggies inside.

Sweet Frozen Treats – While sugar isn’t good for dogs, small quantities of some fruits are safe to share with your dog for sweet frozen treats. To make your dog a fruity popsicle get fresh pineapple, apples or blueberries. Cut up and then liquify fruit in a blender before freezing in ice cube trays overnight and serve to your dog.

Meaty Frozen Treats – To add an extra meaty flavor to your dog’s popsicles, you can add small pieces of unseasoned cooked meat into each ice cube compartment, and then top with either water or broth. Freeze and let your dog enjoy!

Creamy Popsicles – For a creamier treat, use blended bananas or peanut butter, on their own or mixed together. Pour or spoon the peanut butter and/or banana into trays that make very small treats, and freeze overnight. These bite-sized popsicles make great summer training treats, too.

Is My Dog Depressed?

When a dog is suddenly no longer interested in their favorite activities, whether it’s playing Frisbee in the park or chasing squirrels in the backyard, most animal behavior experts will tell you to look for a physical explanation, not a mental-health recommendation. Taking your four-legged friend to the vet for a physical exam should always be the first response to what seems like depression. A change in behavior can usually be attributed to underlying physical conditions like arthritis or pain.

“Depression is typically more of a human term since it has a number of symptoms that have to do with how one feels…and we obviously can’t ask a dog how they’re feeling,” explains Dr. Brian J. Bourquin, veterinarian and owner of the Boston Veterinary Clinic. “However, they can certainly be diagnosed with conditions like Generalized Anxiety Disorder (GAD).”

Signs of Depression in Dogs

Dr. Jill E. Sackman, head of the behavioral medicine service for BluePearl hospitals in Michigan, agrees that while there may not be a clinical diagnosis for depression in veterinary medicine, dogs who are considered depressed by their owners may appear withdrawn, less active, or disinterested in what’s going on around them. However, if your dog is suddenly showing any of these symptoms, she recommends making an appointment with your veterinarian to rule out any medical conditions. “If your dog used to jump up in the morning, gobble down his breakfast, andrun and play outside—and now he just wants to lay in his bed all day—you have to rule out any medical issues first,” she advises.

As humans, we may never know if a dog is truly depressed, but he may exhibit signs and behaviors similar to those associated with depression in people. According to Dr. Karen Sueda, a Diplomate of the American College of Veterinary Behavior and veterinarian practicing at VCA West Los Angeles Animal Hospital in California, these may include lethargy or fatigue, increased sleepiness, loss of interest in activities they once enjoyed, lack of appetite, weight loss or weight gain, restlessness or agitation.

A change in behavior could indicate a number of factors; your dog may just be getting older, or he is reacting to a shift in his day-to-day routine. Sometimes significant changes like the addition of new pets to your home, your dog’s loss of mobility due to ageing, or a family member moving out can put real strain on your dog’s emotional health.

The Difference Between Depression and Anxiety in Dogs

Your dog may not necessarily be depressed, but instead dealing with more common behavioral conditions like fear or anxiety. “We’re asking a different species to live in a human environment and live by ‘human rules’ that they may not comprehend…so it’s understandable that this may lead to fear and anxiety if they don’t understand what we’re asking of them or why,” Dr. Sueda explains.

Signs of fear and anxiety in dogs may include physical indicators like dilated eyes or a tucked tail as well as behavioral signs like panting or trembling, and they may become hyper-vigilant towards their environment and more easily startled, she notes. More subtle signs include displacement behaviors such as lip licking, yawning, scratching, and sniffing that are being done out of context. “This is similar to a nervous person bouncing their leg, biting their nails, or playing with their hair when he or she is anxious,” she explains.

There are things dog lovers can do to help if their dogs seem depressed. Dr. Bourquin recommends seeking out a dog trainer who uses positive reinforcement instead of aversive techniques so as not to intensify your dog’s mental health condition (look for the credentials KPA, CCPDT, and/or this last one is the name of an organization, not the credential they offer).

At home, dog companions can work to create an environment that satisfies their dog’s needs, such as finding activities that engage them and establishing predictable routines—and when necessary, they can also turn to medications. “Lots of dogs need pharmacological help, such as Prozac. Many dog lovers are afraid to give drugs to their dogs, but when we’re talking about GAD, we’re not talking about a dog who gets stressed out when you leave the house…we’re talking about a dog who thinks their life is ending every time you pick up your car keys,” Dr. Bourquin concludes. “But there are definitely things you can do and medications you can offer your dog to get him over the hump.”

Coping with the Heat with My Dogs (and Grandson)

11

This is the time of year when we get days and days – sometimes weeks – of dry, hot weather, with temperatures exceeding 100°F during the day, and only cooling off to the mid 80s at night.

When we have to leave the dogs home, I leave them indoors, with the ceiling fans and cooler on. We have an air conditioner in our new home, but we almost always use the evaporative cooler instead. This is a low-tech device, frequently used in super-dry parts of the country, that essentially sucks air through pads of wet wood fibers and blows this moist, cool air into the house; the evaporation of the moisture lowers the air temperature in the house as much as 20 degrees. As hot as this super-dry environment is, I count myself lucky; it’s much less expensive to run an evaporative cooler (essentially a large fan with a small water pump inside) than air conditioning.

One way or the other, though, steps have to be taken to keep the dogs cool; stories abound of dogs being stricken by heat stroke. If they have ample, deep shade and lots of cool water, most healthy dogs can get through it, though debilitated dogs may lose the ability to withstand the extreme temperatures. (Of course, even healthy dogs who are subjected to exercise in this heat, or left without sufficient protection from the heat, can succumb from the heat stress. See WDJ articles “How to Prevent Heat Stroke” and “Heat Stroke in Dogs” for more information.)

My senior dog Otto has great survival techniques for coping with the heat. He finds the shadiest places in the yard, and digs holes under plants that are watered daily by the sprinkler system, planting himself into these holes and laying low. My younger dog mostly pants and scratches at the door to come inside. “Help! It’s hot!”

Last week, we had a third dog to keep cool, my son’s black coonhound, Cole. He’s used to the much more moderate temperatures in the San Francisco Bay area, where a cool fog is pulled over the entire region any time the temperatures in my valley rise to the “wicked hot” level. Cole pretty much insisted that we go find some nice wet water to get into.

I was more than happy to oblige him. Doing so also made my grandson, visiting for a month this summer from Boston, very happy. He’s an active six-year-old boy – is that an oxymoron? – and nothing makes him happier than throwing rocks into water, unless it is throwing sticks and things for dogs to fetch in the water.

I am incredibly lucky; I live in an area that is rich in open spaces where dogs are allowed to be off-leash – and most of the time, it seems like there is almost no one out there enjoying these spaces with me and my dogs. The Feather River flows through my town, and fills both a huge lake upstream and some smaller, shallow man-made lakes downstream of the Oroville Dam, giving us any number of access points where we can enjoy the water all by ourselves.

All the swimming has been helping Woody get enough exercise, which I’ve been trying to limit because of a recent toe injury; he somehow broke a rear toenail on July 4. Of course, this required yet another emergency visit to the vet (I’ve lost track of how many times this dog has been to the ER…more than he’s been to his regular vet, I think), for a local anesthetic enabling the vet to trim away the broken nail, clean and wrap the paw, antibiotics, and pain meds. The red, raw nub of his nail bed, unprotected by hard nail, has been getting progressively – and painfully – worn down by Woody’s incessant activity, and that’s with me trying to keep him as sedentary as I can. (He also holds that paw up when he goes out to onto the dry pasture to potty, and when crossing the gravel driveway.) Swimming once or twice a day seems like the best solution for now, and serves all of our hot-weather needs.

How are you guys getting through the heat of summer with your dogs?

Free-Roaming Dogs in India, and One of Their Biggest Supporters

0

In the August issue of Whole Dog Journal, we published a column by Linda Case, a dog trainer and author of many books on canine and feline nutrition. Linda also publishes a blog, which goes by the same name as the column in WDJ, The Science Dog. Case’s August column was about studies that were conducted by various researchers to determine whether dogs have a strong preference for meat in their diet, or whether they were simply attracted to the smell of meat, or to higher-protein foods that contained less meat.

Aditi Joshi

One of my duties as the editor of WDJ is to find appropriate photographs (or, less often, illustrations) to accompany our articles. I was temporarily stumped by the prospect of how to illustrate Case’s article in any interesting fashion. Pictures of dogs considering various things to eat? Ho-hum!

But then I remembered that several of the studies that Case’s column referenced were conducted on street dogs in India, and all of a sudden, a light bulb went off in my head. Just a few months ago, I had received a friend request from a young person, Aditi Joshi, who lives in Mumbai, India, and who is very involved with street dogs in India. I had become accustomed to seeing photos taken by Aditi of various free-roaming dogs appear in my Facebook news feed, but I hadn’t yet really investigated who the person was or why photos of dogs on the street were so frequently posted on her page.

I went to Aditi’s Facebook page and started scanning for pictures of dogs in the street in India, preferably eating, and quickly found some that would be perfect to illustrate Case’s article. I sent Aditi a message and asked whether I could pay to use some of her photos with the article.

We quickly struck up a lively correspondence and friendship. Aditi agreed to let me use some photos, and after speaking with her – well, communicating through direct online messaging from our disparate time zones, a half a world apart – about her life and work with street dogs in India, I wrote a sidebar for Linda’s article about how Aditi works to improve relations between street dogs and humans in her neighborhood in Mumbai. Also, I became an instant fan of her work, and with the help of one of Aditi’s San Francisco Bay area friends, set up a GoFundMe campaign in hopes of raising money to help Aditi further her goals.

One of the most astounding things that Aditi told me is that all healthy street dogs have a “right to life” in India. It is estimated that Mumbai is home to about a quarter million street dogs. As long as they are apparently healthy and have been sterilized and vaccinated against rabies (indicated by a notch made in one of their ears), they cannot be detained (except to provide care) or culled. Government agencies and non-governmental welfare organizations that capture dogs in order to vaccinate and sterilize free-roaming dogs are required to release the dogs in the same location they were captured from.

There are organizations that capture and treat severely injured and ill street dogs, and adoption programs aimed at finding homes for some of the street dogs. But the vast majority of dogs in the city continue to live as street dogs.

Aditi focuses her welfare efforts on these dogs, affectionately known as “streeties.” She facilitates community involvement to build a culture of stewardship that views free roaming street dogs as companion animals that the community holds a shared responsibility toward.

Aditi Joshi

Her neighborhood (an area that is about the size of a small college campus) is home to approximately 76 streeties. Over the years Aditi has built a loose network of people in her neighborhood from residents to shop owners, street vendors, domestic workers, garbage collectors, delivery personnel, dog walkers, and doctors who assist in caring for these resident dogs in varying capacities. Through this network she coordinates vaccinations, sterilization, provision of shelter and food, preventative healthcare and vetting, grooming and emergency care in the case of injury or illness on site and in her home.

When properly taken care of, these healthy, settled dogs are the best buffer for minimizing human-animal conflicts and maintaining public health. This is also integral to keeping pet dogs in the community healthy, disease-free, and safe.

Aditi herself owns three former street dogs (complete with the notched ears that indicate they were trapped, neutered, and vaccinated), and oversees cares for 76 streeties in her neighborhood. (Much of the feeding, she notes, is provided by older ladies in the neighborhood – amazing, since a lot of feeders face significant hostility and even violence from people who do not like dogs.) Aditi’s family helps support her to foster additional dogs when one requires medical care.

But Aditi’s central goal is the greater coexistence so these animals don’t just survive but thrive. Her biggest challenge in doing so is building positive human-animal relationships in a context where many people still fear and misunderstand street animals. “There are people who want to show care but don’t actually know how, and some who are afraid and on the fence,” says Aditi. Her current goal is to create a sustainable and scalable program to teach people about safely handling dogs, and to teach street dogs skills that would smooth their integration into human environments.

To help achieve that goal, Aditi is currently enrolled in the prestigious Academy for Dog Trainers (founded and led by renowned California-based trainer/author Jean Donaldson) and is working on the development of curriculum for her street-dog education program. If you’d like to see a video about how Aditi trains street dogs, or to help support Aditi’s work for street dogs in Mumbai, see gofundme.com/aditis-streeties.

As for me, I’m enjoying getting to know the dogs in Aditi’s neighborhood through her photos and stories about them, and daydreaming about a trip to India to see these intelligent, street-savvy dogs in an environment that is completely foreign, but fascinating to me.

Fresh Dog Food: A Review of Refrigerated Dog Food Sold in Stores

Today, more and more passionate, educated, dog-loving entrepreneurs are turning their attention to improving the health of their dogs and innovating new ways to feed quality dog foods. As they do, it’s getting more and more difficult to slot the resulting products into categories for review.

This is just one of the reasons we’ve never before reviewed dog foods in this category – for short, we’ll call it “fresh cooked foods.” When you start drilling down into how fresh dog foods are made, there is so much variety that the category really should be considered as a group with several sub-categories. Some of the products are essentially pureed; others look more like a meatloaf before it’s cooked, complete with chunks of vegetables mixed in; still others present more like those non-refrigerated preserved foods that are sold in plastic tubes, something that looks like a cross between a roll of salami and a tube of liverwurst.

Another big reason for our hesitation: For some years after the first product of this type came on the market, it was the only product in the category, and we weren’t big fans of its ingredients.

freshpet dog food

Also, other products came into the group and didn’t last; we’re thinking here of several companies who sent us samples of foods they made and “canned” in the old-fashioned sense of the word – cooked in glass jars, like your grandmother “puts up” plum jam or stewed tomatoes. It just didn’t seem scalable, and apparently wasn’t (since they are no longer in business).

Cooked Dog Food, Fed Fresh

But let’s focus on the things that these products (mostly) do have in common:

1. All of them have a high meat content – and most of them claim to use meats and perhaps other ingredients that are graded for human consumption. To fully understand these claims, see “What’s Human Quality?” below.

evermore pet food

2. All of them use “fresh” meats; this includes meat that has been frozen to preserve freshness. In other words, none of the meats used were previously cooked before mixing at the point of manufacture.

3. All of the products are cooked – at varying temperatures and with various methods, but they have all been heated to the point that any pathogenic bacteria that may have been present on any ingredient should have been rendered harmless.

freshpet vital dog food

4. Most of them don’t contain preservatives. If it is formulated with fresh ingredients, cooked, immediately chilled or frozen, and shipped in an appropriate cold-shipping container, kept in a refrigerator, and fed promptly after opening, the food shouldn’t need preservatives.

5. All (save one, Freshpet) are available on a subscription basis for direct delivery to your door. (Freshpet is the only product sold in supermarkets; it’s also sold in pet supply stores.)

What Is “Human Quality” Dog Food?

just food for dogs

When discussing their ingredients, many pet food companies use the phrase “human grade.” You have to understand that this is not a legal term, and its misuse probably causes more confusion – some of it intentional – than any other phrase used in the pet food industry.

The legal term for what an ordinary person would think of as “human food” is “edible” – but usually, only food-industry people are familiar with this term. So, in an effort to communicate the quality of their ingredients to consumers, manufacturers of products who use truly edible ingredients will often use some variation of “human grade,” such as “human quality” or “fit for humans.”

lucky dog cuisine

Understand this, though: If the company makes its product in a manufacturing plant that is not USDA-inspected and -approved for the manufacture of edible products, or that manufacturing facility contains even one ingredient that is not edible, then legally, it cannot claim that its products contain either “human grade” or edible ingredients. By law, an edible ingredient is one that has never departed from the custody of USDA-inspected and -approved food growers and processors.

Only those companies whose products were made at a USDA-inspected and -approved kitchen (which are not permitted to contain even one “feed grade” ingredient) can claim that they use edible or human-grade ingredients.

nomnomnow dog food

There are pet food companies who really do buy edible ingredients but don’t make their products in USDA kitchens – and believe me when I say they can be very creative when trying to find phrases that convey the quality of their ingredients without running afoul of state feed control officials (this is who is responsible for surveillance and enforcement of feed labeling laws). The problem for consumers is that there are also pet food companies who likewise use creative language to suggest that their products are made with edible ingredients, when in fact they don’t. Like, not at all.

Moral of the story? If you want to be as certain as one can be that your dog’s food is made with edible ingredients, look for a product made in a USDA-inspected and -approved kitchen. The only other option is to personally know the company’s owners and/or operators, visit the manufacturing site frequently, and inspect the ingredients yourself. There may be a few of you who are able to do all that!

Fresh Dog Food: WDJ’s Usual Food Selection Criteria Apply

ollie fresh dog food

There are certain things we always look for in a wholesome and superior diet for our dogs, no matter what type. Virtually all of the manufacturers offering products in this category use ingredients that meet our usual selection criteria, such as whole, named sources of animal protein (i.e., chicken, beef, and lamb, rather than “meat” or “poultry”); whole food ingredients (such as rice rather than rice flour, and tomatoes rather than tomato pomace); and of course, no artificial colors or flavors.

All of the companies on the following pages offer products that meet all of our selection criteria – but some of the products are higher in quality than others. Some are quite expensive. We wouldn’t necessarily say that cost is a perfect indicator of quality, but it’s a pretty good one. If some of the products are beyond your budget, don’t despair: We would consider every one of these products to be healthier and of a higher quality than any kibble or canned product.

How We Ranked These Fresh Cooked Dog Foods

We are often asked to rank the products that we include in our reviews, and, as always, we have to decline. Only you can decide what you can afford to spend, and only your dog can determine if a particular food will work for him. The product’s performance in your dog is everything – and what works for your dog might be a disaster for mine.

That said . . .

In addition to our normal selection criteria, when shopping for products we feed to our dogs, we also consider some “soft” criteria regarding the companies – factors that have more to do with the feel or personality of the company than the ingredients or protein levels of the foods.

You should be aware that there are pet food company owners who are full of passion and knowledge, but who lack the resources to really pull off top-quality ingredient sourcing or quality control. On the far other end of the spectrum, there are companies who are helmed by folks with amazing business acumen and connections who don’t necessarily live and breathe for dogs. Large and/or well-funded companies have the resources to invest in the best manufacturing equipment and facilities for consistent, safe products – but do the principals care about ingredient quality as much as some of the smaller companies?

We like to buy from the companies that are of a sufficient size to sign manufacturing contracts with reputable manufacturers and invest in employee training and quality control testing and equipment – but not so big that they don’t know exactly where on a map every single ingredient in their products is sourced from.

We appreciate that it can be challenging to identify companies that are occupying that sweet spot, somewhere between enough success and not too much. For what it’s worth, in the following pages, we will try to give you enough information about each company for you to judge where your own zone of comfort might lie: with the giant companies who should have their own plants and control every aspect of manufacturing, but whose formulas are a tad corporate? Or with the smaller outfits who oversee contract manufacturers on just a few production runs each month, but whose ingredients are locally sourced from sustainable farms where the humanely raised food animals live their entire lives on grass?

It’s tough to have to choose, but it seems that when it comes to food, you can’t have it both ways.

Food Bloat in Dogs

4

You made the mistake of leaving your always-ravenous canine at home, unsupervised, with the lid loose on the dog food container. You come home to find an empty dog food bin and a bloated, uncomfortable dog who is retching non-productively. Is this the dreaded GDV (gastric dilatation and volvulus, with volvulus meaning an obstruction caused by a twisting of the stomach or intestines) or just plain ol’ food bloat (gastric dilatation)?

It can be hard to tell in this situation, so an immediate visit to the veterinarian is in order. While knowing that your pet likely ingested a large quantity of food makes gastric dilatation more likely, it is also possible your dog is suffering from GDV. Therefore, this is an emergency; taking a “wait and see” approach is not safe in this scenario.

Food Bloat is Sadly All Too Common in Dogs

As an ER veterinarian, I routinely treated food bloat. The perpetrators were frequently left alone with an easily accessible, large amount of dog (or cat or goat or horse) food. Many dogs will eat until they can hold no more. Beagles and Labradors seem particularly prone to this type of scenario, as they are breeds known to rarely turn down a meal.

Kibble is the most commonly fed type of diet, and unfortunately for our dogs, once it enters the dog’s stomach, it starts absorbing stomach acid and begins to swell. The wet kibble becomes dense and heavy. While your dog may feel the urge to vomit, he may not be able to successfully retch up the mass of food. Thus, the symptoms of a food bloat: abdominal distention, drooling, discomfort, restlessness, and non-productive retching.

food bloat in dogs

Dr. Catherine Ashe

You may be wondering, “Shouldn’t I make my dog vomit if this happens?” Unless you know that the gorging happened within the last five to 10 minutes, forcing your dog to retch is unlikely to be successful. Once moisture gets into a huge amount of kibble, it becomes difficult or impossible for the dog to bring it back up; the sodden mass becomes too heavy for the muscles that, ordinarily, cause vomiting easily.

Hydrogen peroxide, once widely recommended for the induction of vomiting in dogs, has recently fallen out of favor. The use of peroxide can lead to ulcers in the mouth, esophagus, and into the upper and lower GI system. In cases of food bloat, induction of vomiting is best left to the discretion and experience of veterinary professionals, who can use an injectable medication (usually apomorphine) to quickly and more safely induce vomiting.

Food Bloat Treatment: Not as Scary as GDV Treatment

Luckily for your canine friend, food bloat is relatively simple to treat and rarely results in long-term consequences. Your veterinarian will likely x-ray your dog’s abdomen to ensure that this is just gastric dilatation and not a GDV, which calls for immediate surgery to untwist the twisted stomach and/or bowel and perhaps surgically remove damaged intestine.

The veterinarian will also likely start an IV catheter, which allows rapid administration of fluids to correct dehydration and replace electrolyte losses, and to administer medications. In the case of food bloat, if a dog has vomited repeatedly or retched up fluid, he is losing electrolytes and water. This causes dehydration, which is worsened by the stomach pulling in large amounts of fluid to soften and digest the mass of kibble.

Along with rehydration, your veterinarian may use Cerenia (an anti-emetic) to treat ongoing nausea, and sometimes metronidazole, an antibiotic that that can soothe the GI tract by decreasing inflammation. It can also help prevent diarrhea. Other treatments might include probiotics and a bland diet for several days.

Most importantly, your dog will be walked frequently. The exercise stimulates the intestines to move and helps to pass the dog food through the system quickly. Generally 12 to 24 hours in the hospital is all that’s required to help a dog feel better after over-indulging. Just remember to put the food out of reach next time!

What if my Dog Gorged on Something Else?

It’s not uncommon for dogs to gorge on ANY food items when given the opportunity. As an emergency veterinarian, I’ve seen it all. Dogs like to eat corn cobs, rib bones, discarded food, even empty crab and shrimp shells. If you enjoyed eating it, your dog will likely enjoy it, too.

So what will your veterinarian do if your dog has gorged on something unusual? The quick answer is that it depends. If your pet ingested something that could be sharp or cause damage to the esophagus, the veterinarian likely will not induce vomiting. Bones, shells, and corn cobs can be highly traumatic if a dog regurgitates them. They can also cause problems such as pancreatitis, obstruction of the intestines, and perforation. In those cases, your veterinarian may recommend endoscopy to remove the items carefully and in a controlled manner or even an exploratory surgery.
danger!

Rising Bread Dough

Of special note is the danger caused by rising bread dough. Most dogs will eat rising bread left within reach; it apparently smells irresistible to dogs. This can cause symptoms of food bloat, but it is a much more serious concern.

The yeast in bread dough will continue to ferment in a warm, moist environment (like the dog’s stomach). The fermentation process yields ethanol alcohol and a rapidly growing ball of dough. Your dog will be very bloated and uncomfortable, and he may also be drunk!

Bread-dough ingestion can be very serious and requires more aggressive intervention than a standard food bloat. In some cases, the bread can double or triple in size, necessitating surgery to remove it.

Whole Dog Journal covers yeast dough in 13 Household Items Toxic to Dogs, along with twelve other common and dangerous things your dog may decide to eat.

Cloudy Eyes in Dogs

As your canine companion ages, you might begin to notice some cloudiness in his eyes. This is a common age-related change in many breeds of dogs, but it can also indicate illness within the eye or within the body. It is important to know when you should be concerned about cloudy eyes in dogs and when a trip to the veterinarian is in order.

What Do Cloudy Eyes in Dogs Mean?

There are many possible ways in a which a dog’s eyes can look clouded. Often, you are seeing the cloudiness in the lens of the eye – an elastic, transparent structure that lies behind the iris (the pigmented part of the eye) and the pupil (the opening in the center of the eye). Tiny muscle fibers inside the eye contract and relax to makes the lens change thickness and shape; these movements help the dog change focus. As dogs age, certain changes cause the lens to turn white and become visible. When this ordinarily transparent structure develops a cloudy spot or section, the dog’s vision is compromised.

In some cases, however, the cloudiness is not related to the lens. It can be in front of the lens, in the anterior chamber of the eye. Deposits of calcium and fat can also occur in or on the cornea (the translucent dome of the eye).

What Causes Cloudy Eyes in Dogs?

There are dozens of possible causes for cloudy eyes in older dogs. These are the most common:

Corneal Edema in Dogs

The cornea is the transparent dome that covers the eye’s colored iris. Edema (swelling caused by fluid retention) in the cornea can make the eye look hazy; this can appear as a focal area of white or spread to include the whole eye.

Corneal edema can occur following any inflammation or irritation to the cornea. Causes can include corneal ulcers, trauma, corneal endothelial degeneration (see below), and spontaneous idiopathic (no known cause) development. In addition, any of the following conditions can cause corneal edema; the cause of this condition should always be investigated by a veterinarian.

Cataracts in Dogs

A cataract is a clouding of the lens of the eye. Just as with humans, a dog with cataracts will have difficulty seeing at night and experience sensitivity to strong light and glare.

Cataracts progress through four stages of maturity: incipient, immature, mature, and hypermature. In early stages, it can be difficult to differentiate cataracts from another common condition called nuclear sclerosis. If you look closely at the pupil of an eye without cataracts, it will appear to be completely black. But as the cataracts continue to develop, it becomes easy to see clouding of that black dot, especially when the dog’s eye is dilated in low light; the cloudiness becomes more noticeable, then obvious, and will lead to blindness.

It’s important to have suspected cataracts checked out immediately. Catching them early increases the chances of successful management. As cataracts go through the early and then later stages, they can cause significant inflammation in the eye (called uveitis), as well as secondary glaucoma (a common eye condition in which the fluid pressure inside the eye rises to an unhealthy level and damages the optic nerve). Once this happens, those problems must first be resolved before cataract surgery can be attempted.

Once a cataract becomes hyper-mature (also known as a resorbing cataract), it is at risk for rupturing. Once ruptured, the lens material leaks into the eye and causes even more inflammation. This makes successful cataract surgery difficult.

Cataracts often develop as the dog ages, but juvenile and congenital forms do exist, as well.

There are there are dozens of possible causes of cataracts. The causes can be related to illness or be genetic. More than 150 dog breeds have been identified to have inherited forms of cataracts including the Cocker Spaniel, Bichon Frise, Smooth Fox Terrier, Havanese, Miniature Schnauzer, Boston Terrier, Golden Retriever, Labrador Retriever, and Poodle.

There are many systemic causes for cataracts with diabetes being the best-known. With diabetes, as blood sugar levels rise, water is drawn into the lens and causes clouding.

Other associated disorders include trauma, exposure to radiation, nutritional disorders, toxins, and inflammation within the eye.

nuclear sclerosis in dogs

Cataracts can be treated. In the case of inherited/genetic cataracts, the success rate for surgery is as high as 90 percent. During surgery for cataracts, the damaged lens is removed from the eye and replaced with an artificial lens. The surgery must be conducted with specialized equipment by a veterinary ophthalmologist (Diplomate of the American College of Veterinary Ophthalmologists or DACVO).

In cases of diabetic cataracts or other inflammatory cataracts, the prognosis decreases. It is highly dependent on the ability to manage the conditions that cause the inflammation. Controlling blood sugar levels in diabetic dogs will help to lessen the severity of cataracts early in development. In the later stages, the changes become permanent and require surgical correction.

Do “cataract drops” work?

If you do an internet search for “treatment for cataracts in dogs,” you may come across several eye drop products that claim to fix cataracts.

These products usually contain n-acetyl carnosine as the active ingredient. In multiple studies, these drops have failed to improve cataracts.

Newer drugs called “aldose reductase inhibitors” have been shown in a laboratory to delay or prevent cataract formation in diabetic dogs. Unfortunately, they must be given every eight to 12 hours, and if treatment is skipped or missed, complete/mature cataracts can form very rapidly. Due to this, marketing of this product has not been pursued.

cloudy eyes in dogs

At this time, no topical medication on the market will prevent or delay cataract formation. The only definitive treatment for cataracts is surgery.

Nuclear Sclerosis in Dogs

This is a benign, extremely common age-related change to the lens. It occurs in all breeds of dogs, and it does not inhibit vision. The cause is increased density of the fibers within the lens itself. Nuclear sclerosis generally occurs in both eyes at the same rate, whereas cataracts are frequently asymmetrical. There is no need to treat nuclear sclerosis, as it does not interfere with vision. Further, there is no known treatment for this condition.

Corneal Endothelial Degeneration in Dogs

In this condition, the layer of cells at the back of the cornea begin to degenerate. It can be inherited (as in the Chihuahua, Boston Terrier, and Dachshund), or it can be an age-related change.

Initially, the change is often noted as a grayish spot in the middle of the eye that begins to extend to the outer edges. Eventually, the whole eye will have a “white” appearance. It will cause blindness as it progresses. There is no specific treatment for endothelial degeneration, although several techniques have been tried to manage the resulting corneal edema.

Corneal Deposits in Dogs

These manifest as white spots or a white haze over the cornea. Corneal deposits can occur for a variety of reasons. Lipid keratopathy is a well-described condition in which cholesterol is deposited in the cornea. It can occur as part of an inherited disease (in the Airedale, Samoyed, Beagle, Cavalier King Charles Spaniel, and Siberian Husky), be related to high blood cholesterol levels, or caused by inflammatory conditions of the eye. Rarely does this type of deposit affect vision, but monitoring by a veterinarian is important.

cloudy eyes in dogs

Deposits may also be calcium. These are poorly understood but often occur concurrently with an underlying disorder such as Cushing’s disease, kidney failure, or inflammation of the eye. Calcium deposits can irritate the eye and cause corneal ulcers, so treatment is generally aimed at management of the ulcer.

In some cases, an eye drop called sodium EDTA can help to dissolve the calcium deposits. This condition does not have a breed predilection but can occur as dogs age due to underlying systemic illness.

Uveitis in Dogs

This is a general term for inflammation within the eye. The causes are numerous and varied, including toxins, infections, cancers, and trauma. Uveitis may also be idiopathic.

Uveitis can cause a white haze to the eye called “aqueous flare.” It can also cause blood or pus to collect in the eye. Generally, there are other symptoms that occur with the uveitis; the eye will be red, swollen, and painful. Attention is directed at identifying the underlying cause and treating it. With treatment, uveitis will generally resolve.

When Should I Seek Treatment for My Dog’s Cloudy Eyes?

It can be very difficult to distinguish the different conditions from one another. Alert your veterinarian if your dog develops cloudy eyes or is having visual difficulties; a consult with a veterinary ophthalmologist may be in order. A thorough ophthalmic exam should include tear production measurements, fluorescein staining to detect corneal ulcers, measurement of ocular pressure, and a retinal exam. The veterinarian will also examine the eye closely with a bright light to determine where the cloudiness originates. Is it in the lens, the anterior chamber, or within the cornea itself?

With these tests, your veterinarian can generate a list of possible diagnoses and determine if this is a benign age-related change or something that will require medical or surgical therapy to prevent the loss of your dog’s eyesight.

The prognosis for cloudy eyes depends wholly on the underlying cause and whether it can be treated. Since eye conditions can develop and change rapidly, it is always best to consult your veterinarian when you notice anything unusual about your dog’s eyes.

Urinary Tract Infections in Dogs

Urinary tract infections (UTIs) are one of the more common problems seen in small-animal veterinary practice. The definition of a UTI is a colonization of pathological bacteria in the normally sterile environment within the urinary tract. There are many medical conditions that make a dog prone to urinary tract infections, some of which can be prevented. Knowing how to recognize the problem is the first step to getting the proper diagnosis and treatment plan for your dog.

Can Dogs Get UTIs?

The urinary tract is comprised of the kidneys, ureters, bladder, and urethra. Dogs have two bean-shaped kidneys located in the mid abdomen. The kidneys are responsible for filtering blood and excreting waste in the form of urine. As the urine is continually created, it exits each kidney via a small tube called the ureter. The ureters dive into the bladder, which is a muscular collection tank. When the dog is ready to urinate, the muscles of the bladder contract and the urine is emptied through a tube called the urethra, which transports the urine out of the dog.

Problems can develop anywhere along this path, but the most common area of concern is within the bladder itself. When referring to UTIs, veterinarians are almost always referring to infections within the lower urinary tract, or the bladder itself. Infections of the upper urinary tract, or kidneys, are more commonly referred to as pyelonephritis and are more serious in nature.

Signs of a UTI in Dogs

Signs that your dog has a urinary tract infection can be quite variable. Typically, dogs with a lower urinary tract infection do not develop a fever and behave in a normal fashion, other than changing the pattern of their urination habits. Some dogs can be completely asymptomatic, while others show dramatic urgency or frequency while voiding very small volumes of urine. Some dogs will drink excessive amounts of water, and some will lick at their genital region, especially after urinating. Occasionally, an owner will notice hematuria (blood or blood clots in their dog’s urine).

It is important to note, however, that not all dogs with increased frequency, urgency, and hematuria have a urinary tract infections. There are other medical problems that can appear clinically similar, including sterile cystitis (inflammation of the bladder without bacteria), uroliths (bladder stones), and cancer. Therefore, it is very important to make a trip to your veterinarian if you notice any change in your dog’s usual urination pattern.

UTI Diagnosis in Dogs

Diagnosing a UTI is relatively straightforward. Your veterinarian will collect a urine sample and put it through a number of tests.

Typically, the urine is first evaluated macroscopically by analyzing its color and turbidity (cloudiness or clarity). Then the urine is tested for its specific gravity (concentration). Urine that is either too dilute or too concentrated can be an important factor to consider in the analysis of the other urine values and may be an important clue in an underlying medical disorder.

Then the urine is placed on a urine test strip, which checks the biochemical nature of the urine. The pH, protein level, presence of red blood cells, white blood cells, bilirubin, glucose, and ketones are documented.

The last step is to look at the urine under the microscope. Cytology (microscopic analysis) will confirm urine-strip findings and allow for the estimation of the number of red blood cells and white blood cells. Cytologic analysis will also look for the presence of crystals, casts, and bacteria, all of which are important in the diagnosis of a UTI and other urinary-tract disorders.

pee sample

A normal urine sample is sterile (does not contain bacteria). Typically, urine is a clear, light yellow color and microscopically there is very little sediment – no red or white blood cells and no bacteria present. Many parameters can change when a patient has a UTI, so all of the information from the urine test strip along with the cytology of the urine needs to be considered in the diagnosis.

By compiling all of this information your veterinarian will be able to conclude whether or not your dog has an infection of the bladder. However, she will not be able to identify the type of bacteria that caused the infection without further testing.

In order to identify the exact bacteria present, a culture will need to be performed. The urine will be collected in a sterile fashion via cystocentesis (insertion of a needle into the bladder to withdraw a small volume of urine). The urine is then placed into a sterile tube and sent to a laboratory for analysis.

At the laboratory the urine sample will be placed on a petri dish and allowed to incubate for several days. If nothing grows, then it is likely your dog does not have a bacterial urinary tract infection. If bacteria grows, the laboratory technician will identify the bacteria and give your veterinarian a susceptibility pattern, which will tell her which antibiotics will be effective for the present infection.

Pros and Cons of Different Ways to Collect Your Dog’s Urine

URINE COLLECTION TECHNIQUE PROS CONS
FREE CATCH SAMPLE
A clean dish is used to catch urine that your pet is voiding naturally. This is a non-stressful way to collect urine from a healthy pet for a screening analysis.

Normal bacterial flora can contaminate urine as it passes through the penis/prepuce or across the vulva.

Free-caught samples should not be used for culture.

If there is a problem with the urinary tract further down the line from the bladder (prostate or urethra, for example), there may be abnormal cells picked up as the urine leaves the body.

CATHETERIZATION
Urine is collected by insertion of a narrow, flexible tube into the urethral orifice; the tube is then fed directly into the urinary bladder and urine is drained through the tube into a collection syringe. This is a relatively simple procedure to collect urine if the patient is uncomfortable on his back or the bladder is too small to reach via cystocentesis.

The procedure may be slightly uncomfortable for the patient as the catheter is fed through the urethra.

Females dog are very difficult to catheterize.

Sometimes bacteria can be introduced into the bladder from the insertion of the urinary catheter.

CYSTOCENTESIS
Urine is collected via ultrasound-guided needle insertion into the bladder; this is the gold standard for sterile urine collection.

There is no chance for contamination from other parts of the urinary tract.

It allows for visualization of the bladder with the ultrasound, which can help identify bladder masses and uroliths (bladder stones) that may be missed with a free-catch sample.

This can be stressful for some animals because then need to be rolled onto their backs for proper restraint to perform the procedure.

There is a small risk for blood contamination of the urine sample if there is bleeding from the needle insertion site.

Causes of Urinary Tract Infections

A number of medical and physical conditions can make a patient prone to developing an infection in the urinary tract. Females are more susceptible than males for developing a UTI. Bacteria (often fecal contaminants) can more easily travel up the urethra in female dogs due to the relatively short urethral length compared to the male. Also, some female dogs have an anatomical abnormality called a “recessed” or “juvenile” vulva, where the vulva is tucked under an excessive fold of skin, creating a perfect environment for organisms to grow. If this is the case, a straightforward surgical procedure called a vulvoplasty can correct the anatomy to remove the excessive tissue and evert the vulva (make it turn outward).

dog ultrasound

In the male dog – especially the intact male – benign prostatic hypertrophy and prostatitis (infection or inflammation of the prostate gland) can make him susceptible to infection. Castration is often recommended for intact male dogs with recurrent urinary tract infections. However, sex and anatomy are not the only conditions that make dogs prone to infection.

Systemic disease and some medications can also predispose your dog to urinary tract infections. Diseases like diabetes, renal disease, Cushing’s disease, and neurologic disorders can cause UTIs. If your dog develops recurrent urinary tract infections, it may be worth investigating further to see there is an underlying predisposing medical condition. Certain medications, such as prednisone or other immunosuppressive medications, can also make a dog prone to urinary tract disease.

UTI Treatment for Dogs

Treatment for first-time urinary tract infections often involves treatment with broad spectrum antibiotics. However, as bacterial resistance becomes more commonplace in veterinary medicine, cultures are being recommended sooner than previously suggested. Checking a urine sample at the end of the course of antibiotics is wise to confirm the infection has resolved.

Following your veterinarian’s recommendations for treatment and finishing the whole course of antibiotics will help prevent against the development of resistant bacteria.

Occasionally, we see a patient with recurrent urinary tract infections. This can be very frustrating for both the dog owner and the veterinarian. Trying to identify and correct the underlying predisposition is the best course of action to prevent future recurrence. However, this is not always possible.

In these cases, supplementation is sometimes recommended. Other things you can do at home include encouraging water consumption by adding water to your dog’s food and allowing more frequent potty breaks to flush out the bladder.

Urinary tract infections, although common, are typically not very serious in nature. That said, they should never be ignored, as sometimes they are a clue to another, more serious underlying problem. Quick recognition on your part will help with a speedy diagnosis and treatment for your dog.

Supplements That Help Prevent UTIs

  • Cranberry and D-Mannose have been shown to inhibit certain bacteria from binding to the bladder wall

Houseguest Etiquette for Dogs

Those of us who love dogs tend to assume that everyone else in our circle of friends and family does, too. Sadly, that’s not always the case. In fact, even those who do share our passion for canine companions don’t always appreciate the over-enthusiastic attentions of a happy hound, especially when they are trying to enjoy the company of human friends in the comfort of a private home. Whether you are a visitor bringing your own beloved dog with you to someone else’s house, or a host greeting friends at your own front door with your canine family members milling about your feet, here are some tips to help you make sure your dog/human visits go well.

When You Are the Visitor

If you’re headed for a visit to friends or family and you plan to take your dog along, it’s important that you make sure ahead of time that she will be welcome – both now and in the future. Here’s how:

Ask first!

It might be hard to imagine that any close friends or family members of mine would object to a with-dog visit, but it’s far better not to assume. There could be many valid reasons why your dog(s) might not be welcome, including (but not limited to):

• Lease provisions that prohibit the presence of pets

Allergies by one or more residents in the home

• A dog in the home who is not dog-friendly

• Dog fears or phobias by one or more residents (human or otherwise) in the home

• Past bad experiences with visiting dogs (yours or others)

If your host-to-be expresses a strong preference to not have your dog visit with you, respect that wish.

Bring a friendly dog.

If you want to take your dog visiting with you, she should be friendly and well socialized. There is no excuse for bringing along an aggressive dog, thereby risking the safety of others as well as that of your own dog. You would feel awful – and would be legally and morally responsible – if your dog bit or mauled someone during your visit. Plus, many dogs who are forced into situations they cannot handle bite defensively and often end up with a “dangerous dog” label and are ultimately euthanized.

Have a clean canine.

A dirty, smelly dog who sheds all over the house is not a great canine ambassador. Make sure your dog is well groomed prior to your visit and be prepared to wipe paws clean before entering the home. If it’s the time of the year when shedding normally happens, or if your dog is a year-round heavy shedder, warn your host in advance, and offer to do fur clean-up duty at the conclusion of your visit before you leave.

Have a pest-free canine.

Fleas and ticks are even worse than a little doggy dirt and hair. Fleas can hop off your dog and infest a house (and other warm-blooded residents) even long after you are gone. Ticks, carriers of several significant zoonotic (transmissible to humans) diseases including Lyme, ehrlichiosis, and Rocky Mountain spotted fever, can also drop off your dog and climb onto others – and bite or attach to them.

With today’s very effective flea-control products, there are no excuses for having fleas on your dog. Ticks can hitch a ride on your dog despite tick-preventive products (the products are supposed to kill them within 24 hours before they can transmit disease, but don’t prevent them from climbing aboard), so either avoid tick territory for at least 24 hours prior to visiting others, or do a very thorough check for ticks before you arrive.

Train your dog.

At the very least, your dog should be the graduate of a basic force-free good manners class or equivalent training program, be appropriately friendly and social with other humans and friendly with dogs and any other species that might inhabit your host’s home. Polite greeting behavior is a must. More advanced training is even better!

No house soiling or counter surfing allowed, or chewing on non-chew objects. Even if your dog is allowed on furniture in your own home, when your dog is in someone else’s home, getting on the sofas and other furniture should be by invitation only.

Manage your dog.

If your dog is generally social but isn’t yet solid on all her good-manners behaviors, then management is a must. The umbilical cord method is called for here, with you keeping your dog leashed and at your side to prevent any possible social lapses. Crates and portable exercise pens are options for those moments when you want to take a break from your own dog. The leash also allows you to restrain your dog while you inquire whether others want to interact with her, and gives you real-life opportunities to practice her polite greeting behavior. (See “Your Dog’s Behavior: When to Manage, When to Train“.)

If there are children present in your host’s home, you must supervise interactions between your dog and the young humans 100 percent of the time. Even if you are totally confident your dog is good with children, you never know; a child may not know how to be appropriate with your dog and do something that would cause any dog to snap. You must not only supervise, but also be keenly aware of your dog’s body language and intervene if you see any signs that your dog is less than delighted about the attentions of a child. (See “Listening to Your Dog’s Body Language“.)

Potty Before Entering

When humans drive to the home of another human for a visit, they usually want to get out of their cars and go to their friends’ front door as quickly as possible, in a rush to greet their friends – although, sometimes the rush is to ask to use the restroom, especially after a long drive. People often forget that their dogs might also have to use the restroom after a drive, and shortly after they enter their friends’ homes, they are upset and dismayed when their ordinarily housetrained dog pees on their friends’ carpet. Whoops!

If you are going to visit a friend’s house with your dog, before approaching your friends’ front door, walk your dog up and down the sidewalk or in the front yard until she goes potty. Or, if she doesn’t do what you suspect she might have to do, keep her on a leash in your friend’s home and take her outside several times; don’t allow her to be loose or unattended in your friend’s home until you are certain she won’t have an accident. You never know; if your friend has a dog whose own housetraining is not perfect, your dog may detect the scent (perhaps undetectable to your nose) of a past “accident” and conclude that pottying indoors is okay. She’s much less likely to do so if she’s already empty.

Be doubly alert if your dog tends to urine-mark (lift his leg). Under the minor stress of visiting a home where other dogs live, he just might feel compelled to mark indoors, or in an outdoor location (such as on the corner of a nice wicker outdoor sofa or on the back porch rail) where your friend won’t appreciate this.

If you are the resident and your dog is prone to submissive urination or urinating in excitement when people arrive, try to take her outside to go potty as close as possible to the arrival time of your visiting friend. It might also be a good idea to bring her outdoors to greet your friend and his dog, so you don’t have to interrupt your greeting to clean up urine in the house.

When You Are the Host

When you are a dog-owning host, you have a different but similar set of responsibilities to ensure that your guests are comfortable with their canine encounters in your home:

Consider your dog’s needs.

You may have a lovely dog who just doesn’t do well with visitors. It will be challenging to fulfill your role as a host if you are constantly worried about your own dog’s behavior. If she will happily and quietly hang out in a bedroom while your guests are present, put her away so you can enjoy the occasion without stress.

Note: Do not crate or otherwise confine your dog where she will be forced to accept attentions of your visitors. A fearful or unsocialized dog who is crated or tethered might feel trapped and is likely to become even more defensively aggressive if confined where visitors will pass closely by, look at or speak to her, or even worse, poke fingers into a crate or attempt to touch her.

Frozen stuffed Kongs or other long-lasting food toys, with your dog crated if necessary to prevent guarding, can help keep her happy and quiet. If your dog won’t deal well with being isolated in another room, consider asking a friend or family member to take her for the duration of your guests’ visit, or board your dog at a well-researched force-free boarding facility. Note: If you put your dog in another room due to possible aggressive behavior, I strongly recommending padlocking the door to prevent accidental entry into the dog room with potential tragic consequences.

Consider your visitors’ needs.

As lovely as your dog may be, you might, on occasion, have visitors who just don’t appreciate canine attention, hair, or saliva. Perhaps your guest has significant allergies, or is very fearful of dogs.

If you don’t already know how they feel, ask your guests ahead of time if they are comfortable with dogs, and respect their wishes. If they have strong negative feelings, even if your dog is quite friendly, make arrangements as above for your dog to be elsewhere during the visit – either enclosed in another room, at a friend’s house, or boarded.

If you’re not willing to accommodate your guests’ needs by restricting your dog’s access, then don’t invite those guests to your home. Perhaps you can meet them at a restaurant for dinner instead.

Exercise your dog well prior to the arrival of guests.

I like to say, “A tired dog is a happy human.” Be sure to leave time during your visitor preparations for a good exercise session with your dog an hour or so before your company arrives. She may still be excited when guests first walk in, but with much of her energy recently expended, she will settle down and relax much more quickly – and so can you.

Orchestrate controlled greetings.

Even those of us who love dogs don’t necessarily enjoy being bowled over by an enthusiastic canine greeter. If you have one of those, you have several options for orchestrating polite greetings at the front door:

• Confine your dog away from the door until your guest is greeted and settled. You can close your dog in another room, crate her, use baby gates to block her access to the front door, or tether her near the door so she can watch the action but not participate until released. If you use baby gates or tethers, you can invite your guest to help with training by giving him treats and asking him to approach your restrained dog and give her a treat when she sits.

• If your dog has learned a default sit for a treat, you can ask your guests to do a “treat and greet.” Keep a waterproof container of non-perishable treats outside your front door, and ask your guest to help himself to several before he enters the house. When he does, coach him to hold the treat near his chest (or whatever body language signals a sit to your dog) and then give your dog a treat when her bottom is securely resting on the floor. Alternatively, you can have him play “Find it!” with your dog by tossing small handfuls of tiny treats on the ground, thereby redirecting your dog’s attention – and her energy – away from himself and toward the floor.

• Here is an alternative for dogs who will default-sit for a toy: Keep a basket of toys outside your front door. Ask your guest to grab a couple of toys on the way in and wait for your dog to sit; as soon as she does, have your guest toss a toy a good distance away. Your dog may run after it and play with it or bring it back to your guest. If she brings it back, he can prompt a sit with the second toy, and then toss that one. The dog will likely drop the first as she runs after the second.

• You can also use high-tech options like the Treat & Train or Pet Tutor. These remote-controlled devices can be used creatively to invite your dog away from the door as your visitors enter.

Train your dog.

Of course, good socialization and training are always your best options. At the very least, your dog should be the graduate of a basic force-free good manners class or equivalent training program, be appropriately friendly and social with other humans (and any other species your guests may be bringing with them). Polite greeting behavior is a must. More advanced training is, of course, even better! A well-trained “go to your place” behavior can be invaluable for helping your guests feel comfortable with your dog’s presence.

Manage your dog.

As described in the “Visitor” section, if your dog isn’t reliably trained and generally well-behaved, or if you just want a break from dog-supervision duties, then management is a must. Leashes, tethers, baby gates, crates, and closed rooms are all viable management options to help keep things under control when guests are in your home. And, even if your dog is allowed on furniture, be courteous and give your guests the option of not sharing the sofa with your dog if they’d prefer not to do so.

If your visitors are bringing children with them, you must supervise interactions between your dog and the young humans 100 percent of the time, even if you are totally confident your dog is good with children. You must not only supervise, but also be keenly aware of your dog’s body language and intervene if you see any signs that your dog is less than delighted about the attentions of a child. Err on the side of caution.

And finally, do not rely on your guests to do the supervising. They don’t know your dog and may not be skilled at reading and understanding her body language signals of stress or discomfort.

Fair Warning

Don’t take your friend’s dog’s training for granted. Perhaps your dog has been trained to never run out of your front door without explicit permission, but a door left open just for a few moments (say, to fetch more groceries from the car) might be the beginning of a tragic lost-dog saga if your friend’s dog lacks this training skill. Your cat or parrot might be safe from your dog, but can lose their lives in a matter of moments if your friend’s dog is more predatory and your unsuspecting pets were in harm’s way.
Though it’s hard to anticipate every potential tragedy that can occur with dogs in new places, alert your friend to the most likely dangers to her dog or to your family members. Let her know if your yard is not securely fenced, for example, or where your chicken or rabbit pen is located.

Keep in mind that a portable exercise pen is a terrific management tool that can be deployed to prevent lots of disasters. If your friend’s dog is a door-darter, you can set up a pen in an “air-lock” arrangement, so she can’t escape if the door is left open by accident, or so someone who is not savvy about the door-darter’s techniques can’t accidentally let her escape. You can also use an exercise pen to create a larger safe zone for your bird’s cage or your elderly cat’s food bowls and litter box.

We, the Dog Lovers

It really is incumbent on those of us who love dogs to make sure that others have good experiences with our canine companions, whether they are guests in our homes, or we are guests in theirs. Regardless of the circumstances, and regardless of your dog’s training and socialization, wherever you are you must always be on the alert for signs that your dog is stressed and needs a break, or that others are uncomfortable with her presence and you need to give them a break. Without that, our dogs will continue to find themselves less welcome and less appreciated by the rest of the world.

In contrast, though, every good canine ambassador will help open doors for dogs in the world, rather than closing them.

Free-Ranging Dogs Give Us Insight on Canine Protein Preferences

0

Anyone who lives with dogs is aware that dogs are almost universally attracted to meaty foods and treats. Trainers use these preferences to select different levels of “treat value” for dogs and almost invariably, the treats that are of highest value to a dog are those that have a meaty texture, smell, and (we assume) taste.

It is also true that most dogs are highly attracted to and readily consume high-protein diets that include cooked, extruded, or raw meat of various types.

Are these preferences a vestige of the dog’s predatory past? If so, are such preferences something that dogs are born with, or is there a strong influence of learning and environment on our dogs’ apparent taste for meat?

A recent set of experiments conducted by researchers who study free-ranging dogs in India asked these questions and provide us with some new information.

Street Dog Diet Studies

Free-ranging dogs exist in numerous countries around the world, including Mexico, Italy, Nepal, Japan, many African countries, and India. They survive almost entirely by scavenging and occasionally augment their diet by begging and hunting small animals.

In India, the history of free-ranging dogs is well-documented, extending back to the 9th century BC and representing more than 1,000 generations of dogs.

Indian free-ranging dogs consume a diet that is rich in carbohydrate (biscuits, bread, and rice) and relatively low in protein. The protein that is consumed is in the form of scraps of meat or fish adhering to bones, decomposing meat, and carcass remains.

Domestic dogs are better adapted to scavenging and a diet that is higher in carbohydrate foods than were their wolf-like ancestors because of changes in foraging behavior (increased scavenging/decreased pack hunting) and an enhanced ability to digest starch (increased copies of the gene AMY2B, the gene that codes for pancreatic amylase; for more about this, see “Dogs and Carbs: It’s Complicated“).

However, just because dogs can consume and digest diets that contain a high proportion of carbohydrate (starches), it does not necessarily follow that they prefer such diets or that it is the healthiest or best way to feed them.

Although the study of these free-ranging dogs could shed light on many interesting questions, the two that the Indian researchers attempted to answer were: “Do dogs have a strong preference for meat in their diet?”  and, “If so, is such a preference innate (are puppies are born with this preference) or is it reliant upon or strongly influenced by learning?” 

In the first study, the researchers offered 30 free-ranging dogs a variety of food choices in four separate experiments:

• In the first, dogs chose between bread, bread soaked in water, and bread soaked in chicken broth.

• The dogs selected between bread, bread soaked in gravy, and cooked chicken in the second experiment.

• The third offered the dogs choices between dry dog kibble or bread soaked in varying concentrations of chicken broth.

• The final experiment offered the dogs varying combinations of bread and dog food kibble, soaked with different concentrations of chicken broth.

The purpose of this final set of choices was to separate the factors of meat smell from nutrient (protein) content, because dogs have been previously shown to be capable of self-selecting a diet according to its macronutrient (protein/fat/carbohydrate) content.

Street Dog Study Results

The following preferences were found in the adult, free-ranging dogs:

Meat (smell) beats carbs. The dogs consistently chose bread soaked in chicken broth over dry bread or bread soaked in water, even though chicken broth contains only a small amount of actual protein. When allowed to choose only visually, they selected chicken meat over chicken-soaked bread or dry bread.

Smell beats all. When the dogs were offered kibble (high protein food) or bread (low protein food) soaked with varying concentrations of chicken broth, they consumed all of the foods equally, showing no absolute preference in terms of the quantity that was consumed.

However, the order of selection depended completely upon how much chicken broth was soaking the food, regardless of its nutrient content. In other words, the dogs chose according to smell, not in accordance with the actual amount of meat protein present in the food.

Rule of thumb: Choose the food that smells the most intensely of meat first. The cumulative results of the four experiments support the existence of the above rule of thumb for food choice. This means that the dogs preferred foods that smelled of meat (but that were not necessarily good sources of protein) over those that smelled less meaty, even when the less meaty-smelling foods actually contained more meat ingredients and a higher protein content.

This of course, makes sense, since in nature, a stronger meat smell is highly correlated with high meat and protein content and invariably predicts higher meat quantity. This relationship only becomes skewed when clever experimenters enter the picture and mess with it.

The authors concluded that while domestic dogs have adapted a scavenging lifestyle, they appear to have done so without giving up a strong preference for meat. They suggest that while the domestic dog has indeed evolved to more efficiently digest carbohydrate and exist on a carbohydrate-rich scavenged diet, they continue to be strongly attracted to the smell of meat and preferentially select meaty-smelling foods. (Not surprising at all to most dog owners; but again, good to have science backing up experiences and beliefs).

But wait, they’re not finished. The same researchers then asked, “Are domestic dogs born with a preference for meat, or is it a learned trait?”

The researchers conducted the same series of the experiments described above with the puppies of free-ranging dogs. The puppies were 8 to 10 weeks of age at the time of testing. Using a clever design, they found that:

Puppies do not discriminate. Unlike the adult dogs, puppies near weaning age showed no clear preference for foods that smelled strongly of meat and chose each food selection equally, regardless of how intensely the food smelled of meat.

Dogs use a sniff and snatch strategy. While the adult dogs tended to first smell and inspect all available food choices before choosing and consuming one, puppies did not show this behavior. Rather, they would smell a food, eat it, and then move to the next food, showing little to no preference. The vast majority (89 percent) of choices made by puppies followed this behavior pattern.

The authors speculate that because puppies consume a protein-rich diet in the form of their mother’s milk, there is little selective pressure for an innate selection bias toward the smell of meat.

It is only after weaning, when pups begin to scavenge, that preferentially selecting foods that smell like meat (and are correlated with a high protein content) becomes important. They suggest that, as has been shown in a number of other species, puppies learn their food selection preferences from the mother (i.e., cultural transmission of knowledge) and then as they mature and begin to scavenge, operantly.

Take-Away for People with Pet Dogs

The first study’s results with adult, free-ranging dogs tell us that the dogs in this set of experiments were selecting foods based primarily on smell rather than an ability to discern actual meat content. The adult dogs were operating under the (pretty efficient) rule of “If it smells like meat, eat it.” (We all know and love dogs who do this!)

This strategy is probably strongly selected for in environments where resources are limited, there are few energy- and protein-dense foods available, and competition between dogs is high. This is not really a surprising result – except for the fact that the authors found that the scent of meat was more important than the food’s actual meat (or protein) content.

Newly weaned puppies, in contrast, lack this choice bias and appear to learn to choose “meaty” foods after weaning, either from the food choices of their mother, operantly, or most likely, a combination of the two.

So, what does this tell us about feeding our own dogs? These results suggest that while dogs are predisposed to enjoy the taste of meat ingredients and clearly prefer these foods, puppies do not appear to be born with an attraction to the smell of meat per se; these preferences are influenced by learning early in life.

On a practical level, these data, along with those of earlier studies of taste preferences in dogs, tell us that the foods that are offered to a puppy at a young age should be expected to strongly influence the pup’s food and taste preferences as an adult dog.

An Advocate for “Streeties” in Mumbai 

The photos we used to accompany this article were taken by Aditi Joshi, a street-dog advocate who lives in Mumbai, India, a city that is home to an estimated 250,000 street dogs. Several government agencies and NGOs are involved in vaccination and sterilization programs, as well as treating severely injured and ill street dogs, but they do not address everyday caregiving. There are adoption programs aimed at finding homes for these dogs, but the vast majority of dogs in the city continue to live as street dogs.

By last count, Aditi’s neighborhood is home to 76 “streeties,” as the dogs are affectionately called. Over the years, Aditi has worked to build a culture of stewardship that views the streeties as companions for which the community shares responsibility, thus helping to bridge the gap in the care they receive. She has built a loose network of people in her neighborhood – residents, shop owners, street vendors, domestic workers, garbage collectors, delivery personnel, dog walkers, and doctors – who assist in caring for these resident dogs in varying capacities. Through this network, she coordinates preventative health care (vaccinations and sterilization), provision of shelter and food, grooming, and emergency care in the case of injury or illness, both on site and in her home.

“When cared for, these healthy, settled dogs are the best buffer for minimizing human-animal conflicts and maintaining public health,” Aditi says. “This is also integral to keeping pet dogs in the community healthy, disease-free, and safe.”

Aditi’s biggest challenge is building positive human-animal relationships in a context where many people still fear and misunderstand street animals. Her current goal is to create a sustainable and scalable program to teach people about safely interacting with dogs, and to teach street dogs skills that would smooth their integration into human environments.

To help achieve that goal, Aditi is currently enrolled in the prestigious Academy for Dog Trainers (founded and led by Jean Donaldson) and is working on the development of curriculum for her street-dog education program. If you’d like to see a video about how Aditi trains street dogs, or to help support Aditi’s work for street dogs in Mumbai, see her GoFundMe page.

Informing? Or Selling?

A couple of days ago, I received a text from a dog-training client, wondering about a video she had just watched—and which she linked in the text. “Is meat meal bad for dogs?” she asked. She followed that message with, “I get that she’s selling her own pet food, but is it (meat meal) that bad?”
