Heatstroke is a serious condition that unfortunately occurs all too often in dogs and cats. Your pet can succumb to heatstroke when his body’s core temperature rises excessively — typically to 105 degrees Fahrenheit or higher. Dogs and cats are especially vulnerable to heatstroke because their furry bodies cannot sweat to dissipate heat. Rather they pant or breathe rapidly to cool themselves. When they are unable to effectively cool themselves, their core temperature rises rapidly. This can lead to serious and sometimes fatal complications including seizures, organ failure, and clotting problems. Any animal suspected of having heatstroke is experiencing a medical emergency and should receive immediate veterinary treatment.
Causes
Leaving a pet inside a parked car is the most common cause of heatstroke. Contrary to popular belief, “cracking a window” is not sufficient to protect your animal from this potentially deadly problem. The American Veterinary Medical Association (AVMA) urges pet owners to “love ’em and leave ’em” in terms of bringing pets along with you in the car. “Please leave your pets at home when you can,” the AVMA cautions. “They’ll be safe and happily waiting for you to come home.” It also reports that a study published in the journal “Pediatrics” confirms that the interior temperature of parked cars rises steadily over time, even on days when temperatures are only moderately warm.
Pets can also experience heatstroke if they exercise too much on hot humid days, or if they are unable to get out of the sun and into some shade. Certain breeds of dogs are predisposed to heatstroke. These are the dogs with short noses such as Pekingese, pugs, Lhasa apsos, and Boston terriers. These short-nosed dogs have airways that are not as efficient at cooling when they pant. Overweight or obese dogs are also prone to heatstroke, as are dogs or cats with other airway problems. Cats are often subjected to heat stroke by sneaking unnoticed into parked cars or hot attics, then becoming trapped. It is important to account for all your animals after working in an area that could be a heatstroke trap.
