Prevention, Signs & Treatment of Heat Stroke in Dogs

As temperatures rise, so does the risk of heat stroke in dogs. Unlike humans, who can cool down by sweating, dogs rely primarily on panting and releasing heat through their paws. This limited cooling ability makes them highly susceptible to heat stroke, a life-threatening condition that requires immediate attention. In this blog post, we’ll cover what heat stroke is, how to recognize the signs, ways to prevent it, and what to do if your dog shows symptoms.


Heat stroke occurs when a dog’s body temperature rises to dangerous levels, typically above 104°F or 40°C. If not treated quickly, heat stroke can cause organ failure, brain damage, and even death. Dogs can suffer from heat stroke during hot weather, especially if they’re exercising, left in a hot car, or don’t have access to shade or water. Even short exposure to high temperatures can be enough to push a dog into heat stroke.


Some dogs are more vulnerable to heat stroke than others. Brachycephalic breeds (like Bulldogs, Pugs, and Boxers) have shorter snouts, which makes it harder for them to pant effectively and cool down. Puppies, senior dogs, and those with health conditions are also at higher risk. Additionally, overweight dogs and dogs with thick coats are more likely to overheat.


The sooner you recognize the symptoms of heat stroke, the better the chances of saving your dog’s life. Common signs include:

  • Heavy Panting: Excessive and rapid panting is often the first sign of heat stroke.

  • Drooling: Thick, sticky saliva and drooling can indicate overheating.

  • Red or Pale Gums and Tongue: The gums may turn bright red initially, then pale as the condition worsens.

  • Weakness or Lethargy: A dog suffering from heat stroke may appear disoriented, stumble, or collapse.

  • Vomiting and Diarrhea: These symptoms are often accompanied by signs of distress.

  • Seizures or Loss of Consciousness: In severe cases, a dog may have seizures or lose consciousness.


Prevention is key when it comes to heat stroke. Here’s how you can keep your dog safe during hot weather:

  1. Never Leave Your Dog in a Hot Car: Even with the windows cracked, temperatures inside a car can reach dangerous levels in just minutes.

  2. Provide Plenty of Water and Shade: Always ensure your dog has access to fresh water and a cool, shaded area when outdoors.

  3. Avoid Exercise During Peak Heat: Schedule walks and playtime for early morning or late evening when it’s cooler. On very hot days, it’s best to skip strenuous activities altogether.

  4. Be Mindful of Humidity: High humidity can make it even harder for dogs to cool down, so take this into account when planning outdoor time.

  5. Consider Cooling Products: Cooling vests, mats, and bandanas can help keep your dog cool. You can also provide a shallow pool of water for them to splash in.


If you suspect your dog is suffering from heat stroke, it’s crucial to act fast:

  1. Move to a Cooler Area: Immediately take your dog to a cool, shaded place, preferably indoors.

  2. Start Cooling Your Dog Down: Use cool (not cold) water to gently wet your dog’s body, focusing on the belly, paws, and armpits. You can also use damp towels, but be sure to keep them cool and not let them trap heat. Avoid using ice, as this can constrict blood vessels and worsen the situation.

  3. Offer Water: Allow your dog to drink small amounts of cool water, but don’t force it if they’re not interested.

  4. Head to the Vet Immediately: Heat stroke is a medical emergency. Even if your dog seems to be recovering, it’s essential to seek veterinary care right away, as there could be internal damage.


Heat stroke is a serious and often preventable condition that every dog owner should be aware of. By taking precautions, staying informed, and knowing the signs, you can protect your dog from the dangers of overheating. During the warmer months, always prioritize your dog’s comfort and safety. Remember, it’s better to skip a walk or outdoor activity than to put your furry friend at risk of heat stroke. Stay vigilant, and keep your dog cool, hydrated, and healthy all summer long.
