Heatstroke in dogs is life-threatening and can also result in very serious complications. Jerry Klein, Chief Veterinary Officer for the AKC. The degree of damage is determined by how high a body temperature is reached and how long the animal is exposed,” says Dr. “Heatstroke usually occurs when high ambient temperature overcomes the dog’s ability to dissipate heat. The bottom surfaces of paws can sweat, but not enough to make a difference. Blood vessels, especially in the ears and face, expand, bringing overheated blood closer to the surface to cool down. When dogs pant, they evaporate moisture from their tongues, nasal passages, and the lining of their lungs, and this cools them down as air passes over the moist tissue. When the body temperature is above 105 degrees F, the dog may be suffering from heatstroke.ĭogs have only a couple of ways to cool off-blood vessel expansion and panting. When a dog’s internal body temperature goes above a normal temperature of 101.5 degrees Fahrenheit (F), this is a fever and is called hyperthermia. Watch for early signs of heatstroke (also known as hyperthermia) in your dog to avoid serious outcomes. Dogs are notoriously bad at dissipating body heat.
