Overweight Dogs

Compare the actions and functions of the musculoskeletal system to a finely tuned symphonic orchestra. Each and every instrument (each of the dozens of independent muscles in the dog) contributes to the whole. For one instrument to be heard above the rest, the sounds from other instruments must be softened – and for one set of muscles to flex or contract a joint, that joint’s muscles of extension must relax, and vice versa. The music of the muscles is this month’s stop on the Tour of the Dog.

Many people are aware that hypo-thyroidism (low thyroid function) is a medical condition that can cause an afflicted dog to become lethargic, dull, and fat. But far too few dog owners are aware of the behavioral symptoms that hypothyroid can cause. This is unfortunate, since these symptoms include unexplainable aggression, so-called rage syndrome

Recent studies indicate that up to 40 percent of dogs in the United States may be obese. The risks associated with canine obesity include musculoskeletal disorders such as osteoarthritis, compromised immune function, problems during surgical procedures, delayed wound healing, skin infections, and diabetes.

Obesity has been defined as a body weight 10 to 20 percent above the ideal weight for that individual dog. The rule of thumb offered by most sources is that if you sweep your fingers lightly over your dog’s ribs and shoulders you should be able to feel the outline of the bones. If you must use pressure to find the ribs, your dog is overweight. Viewed from above, your dog should have a noticeable waist. If Bowser fails either of these two tests, it’s time for doggy dieting. Veterinarians today consider obesity to be the leading health problem among our dogs and cats. According to the U.C. Davis School of Veterinary Medicine’s Book of Dogs, this manifestation of malnutrition affects an estimated 25-44 percent of our canine companions.

Diabetes is a common and serious problem in pets. Formally known as diabetes mellitus (the sweet sickness), it’s a disorder of the pancreas gland. The pancreas produces a hormone called insulin, whose purpose is to drive nutrients, specifically glucose, or blood sugar, into the cells. It’s the body’s most important fuel molecule. Good management is the key to longevity for diabetic dogs.
