As the temperatures rise, humans have the ability to sweat and cool down, but our canine companions face a tougher challenge. With their fur coats, dogs struggle to regulate their body temperature effectively, making them susceptible to heatstroke. This condition is not only common but can also be fatal, yet it is remarkably easy to prevent.
Unlike humans, dogs have only a few sweat glands located on their paws and snouts, which do not function efficiently. They primarily rely on panting to cool down. When the heat becomes overwhelming, and panting isn’t enough, hyperthermia can occur. A dog’s normal body temperature is around 102.5 degrees; anything higher than this can lead to serious health risks.
According to the American Kennel Club’s Canine Health Foundation, heatstroke in dogs is triggered by excessive heat exposure—such as being left in a hot car or locked outside under the sun—or by overexertion, even in milder temperatures. For instance, sled dogs during the Iditarod can suffer from exertion-related hyperthermia, which highlights how serious this issue can be.
Understanding Heatstroke vs. Heat Exhaustion in Dogs
As a dog’s body temperature rises, different symptoms may manifest:
- Heat Stress: Initially, dogs may exhibit excessive panting, with a flat tongue and pulled-back cheeks, exposing their teeth and gums.
- Heat Exhaustion: If not addressed, heat stress can escalate to heat exhaustion. Symptoms include uncontrollable panting, vomiting, diarrhea, stumbling, and potentially losing consciousness.
- Heatstroke: This is the most severe and can lead to seizures, coma, or even death.
How to Treat Heatstroke in Dogs
If a dog shows signs of heatstroke, immediate action is critical. Veterinarian Lisa Anderson stresses the importance of cooling the dog down and seeking veterinary care without delay. “Hyperthermia is a medical emergency,” she warns. To cool a dog, apply cool—never cold—water to their head, stomach, armpits, and paws. It’s essential to keep air circulating to promote heat loss until you reach the vet.
The outcome for dogs experiencing heatstroke depends on factors like duration of exposure, environmental temperature, and the pet’s age. “Most healthy dogs can recover quickly if treated promptly,” Anderson explains. However, some may suffer permanent organ damage or complications later. Importantly, dogs that recover from heatstroke are at a higher risk for future incidents due to potential damage to their thermoregulatory system.
Heatstroke in Cats
While heatstroke is less common in cats, they are still at risk. Similar to dogs, cats have limited sweat glands, and heatstroke usually results from being trapped in a hot environment, like a car or a clothes dryer. Older, overweight cats or breeds with flat faces are particularly vulnerable. Symptoms include excessive panting, lethargy, disorientation, vomiting, and thick saliva.
How to Treat Heatstroke in Cats
To help a cat experiencing heatstroke, remove them from the heat and place them on a wet towel. Offer water—consider adding chicken broth or tuna juice to encourage drinking. Use cool water to spray them while directing a fan toward them to aid evaporation. Keep track of the time to inform your veterinarian, and stop cooling once their temperature reaches 103.5 degrees. Afterward, dry the cat and head to the vet immediately.
Key Prevention Tips
Summer can be challenging for pets. Besides being vigilant about heatstroke, avoid walking dogs on hot surfaces. To test the pavement’s heat, place your hand on it; if it burns, it’s too hot for your pet’s paws. Always carry plenty of water for hydration.
Common Questions About Heatstroke in Dogs
- How long should a dog be outside in the heat? Limit outdoor time to about 15 minutes if temperatures exceed 90 degrees, especially during humidity.
- Can the heat affect my dog’s bowels? Yes, heat exhaustion can lead to gastrointestinal issues, including diarrhea.
- How long does heatstroke last in dogs? The symptoms may resolve quickly, but full recovery can take days or even weeks, depending on severity.
