The brachycephalic breeds – such as Pugs, Boston Terriers, Boxers, Bulldogs – are particularly at risk of heat stress, says Eileen Fatcheric, DVM, of Syracuse, New York. “The only way dogs have to thermoregulate their bodies is panting, which is air flow over the respiratory system. These dogs are particularly at risk for heat stress because of the shape and design of the dog’s throat.”
Awareness is important, Dr. Fatcheric says. “The early symptoms of heat stress are easy to miss – wobbling and increased body temperature. Owners of these breeds need to pay closer-than-average attention to their dogs’ behavior and body language.”
