Heat Stroke in Dogs

It's summer outside and the living is easy -- right? Not for dogs who are left outside on a warm day. Although dogs have sweat glands on their feet, they rely almost exclusively on panting to dispel excess body heat. The hot weather raises the probability of heat stroke.

On a warm day, the temperature in a parked car can reach 160' in a matter of minutes, even with partially opened windows. Never leave your dog in a car on a warm day -- even if it's "just for a few minutes." Sitting in a hot car is not the only way to acquire heat stroke, although it is the most common. Any dog exercising on a hot, humid day, even with plenty of water, can get heat stroke. Be careful when exercising your dog in the summer. Short-nosed breeds, like pugs, boxers, and bulldogs, are especially susceptible, as are double-coated breeds like German Shepherds and Old English Sheepdogs.

Signs of heat stress may include heavy panting, an increased heart rate, and gasping for breath. The mucus membranes get a dark bluish tinge and some dogs begin vomiting. Other dogs may appear disorientated and begin to have seizures. If your dog gets overheated, you must lower his body temperature immediately! Get the dog out of the heat and put cool, water-soaked towels on his head, chest, and neck. Spray him lightly with a hose. Be careful the water is not too cold, as cooling off too quickly can cause problems, as well. After cooling down, take your dog to the vet for a checkup. Heatstroke can lead to serious damage to the kidneys, liver, heart and lungs.

The Minnesota Valley Humane Society urges you to keep your pet home on hot days. We also recommend you keep a supply of our red Hot Dog cards in your car to warn others of the danger of heat stroke.
