Even on a cool day (the mid-60s), the temperature in a closed car rises to 130 degrees Fahrenheit in minutes. Don’t leave your dog in the car-with windows cracked or not.Ensure that your dog has fresh water and shade, with short periods outside in hot weather.Carrie Forsyth, who breeds and shows Pekingese, avoids the problem of overheating by selecting against pinched nostrils and other upper-respiratory abnormalities in her breeding program. “Careful breeding of brachycephalic dogs should make good airways a priority in breeding stock,” Grebe says. Over time, the increased effort to breathe causes a progressive inward collapse of the walls of the larynx, which may be fatal. Feel the walls of your larynx and trachea being sucked in.” Grebe explains, “Try pinching your nose shut, close your mouth, and inhale. Eventually, the elasticity of the respiratory system is lost with repeated challenges, and with an increased effort to breathe, the walls of the airway may be drawn inward. Grebe warns, “Anything that causes brachycephalic dogs to breathe harder places additional stress on their airways, whether it is overheating on a hot day, excitement that causes panting, or exercise that increases the oxygen demand of their muscles, requiring more strenuous breathing.”Īdditionally, chronic respiratory challenges tend to cause irritation with more salivation and swelling in the throat, further impairing air movement as passages narrow. Why Flat-Faced Dogs Overheat Easilyīrachycephalic dogs-with shorter, pushed-in muzzles, shortened facial bones, and noses that are pushed in and upward-tend to be more heat-sensitive, and their airways can be less efficient at moving air in and out of the lungs and thus more susceptible to overheating. Even if you can cool him and he acts normal, rush him to an emergency clinic because his organs may have already been damaged and death could follow. Unable to stand, he may have a seizure, become comatose, and die. As he dehydrates, the saliva thickens, and he may vomit and have diarrhea. He may gasp for air, and the entire mouth will become grayish to purple because of the unmet oxygen demand. Frantic panting, extreme salivation, bright-red membranes, and labored breathing are clear warning signs that your dog is overheated and may quickly progress to a metabolic meltdown as his temperature rises to over 106 degrees Fahrenheit and he can no longer cool themself. But if the outside environment is also very moist, less evaporation and cooling occur, resulting in a reduced tolerance for hot, humid weather and a greater danger of overheating.Īs a dog’s temperature rises, blood rushes to the surfaces of the tongue, gums, and membranes to help transfer excess heat. Panting animals, then, need adequate cool water to drink on warm days to keep those airways moist for this process, maintaining a fragile temperature balance. After the cooler air is sucked into the lungs, hot, moist air is exhaled through the mouth over the dripping tongue, expelling excess body heat. The breathing rate increases from 40 to 400 breaths per minute, with an occasional deep breath. ![]() Cooler, drier air is inhaled through the nose and upper airways, and in the lungs, it is exchanged for warm, moist air as evaporative cooling takes place, which is the dog’s equivalent of our sweating mechanism. Panting is evaporative cooling, canine-style. In contrast, dogs pant because they have few sweat glands. Evaporation of this sweat cools us, and a fan makes it happen faster. When humans sweat, heat is transferred from the moisture over our entire body to drier, cooler air around it. But when it rises only a few degrees over 102 degrees Fahrenheit, a dog is overheated and action must be taken before heat exhaustion occurs. “Dogs don’t sweat,” former French Bulldog Club of America president Jan Grebe, Ph.D., reminds us.Įxercise, excitement, or infection can cause a dog’s temperature to rise normally. Could this happen to your dogs? Why Dogs Overheat The house warmed quickly, and there was nowhere to find relief. Jazz and Ginger, gated in a sunny room, panted anxiously as they began to overheat. Unfortunately, hours later, the power failed. Before leaving for work on a summer morning, Meredith turned on the air conditioner to keep her two beloved pets comfortable.
