Just like humans, dogs and cats can suffer heatstroke — severe overheating that may cause organ failure, brain damage and even death. Unfortunately, some of the most alarming symptoms in humans, such as confusion or weird behavior changes, are harder to spot in cats and dogs.
Watch for these signs: heavy panting, collapse or staggering, drooling, vomiting, lethargy, glassy eyes, rapid heartbeat and, naturally (since the condition is caused by overheating), unusually high body temperature. Very old pets, very young ones and the overweight are at the greatest risk, and certain breeds with short noses — think pugs, boxers and bulldogs among dogs, and Persians and exotics among cats — will have more trouble with the heat because they can’t pant as well, according to Petfinder.com.
If you suspect heatstroke, move your pet somewhere cool, apply cool compresses or water, and get your dog or cat to a vet as soon as you possibly can. Heatstroke is a medical emergency, and prompt medical attention may save a life.
