With summer fast approaching, pet owners need to be aware of heatstroke in dogs. Heatstroke is a dangerous illness that can be life-threatening. However, you can take steps to prevent it, recognize the signs, and get help if needed.
Read on to better understand heatstroke in dogs and keep your pup safe and happy during the warmer months ahead. Note that heatstroke is common in puppies as well as senior dogs, and ranks among the most prevalent issues affecting senior dogs.
What Is Heatstroke?
Heatstroke occurs when a dog’s body temperature rises far above the normal range of 101–102.5°F (38.3–39.2°C). It relates to hyperthermia, a general term for elevated body temperature. Heatstroke refers specifically to a severely elevated body temperature — 105°F or more — caused by environmental factors.
Heatstroke in dogs is a medical emergency. Without prompt treatment, it can lead to organ failure, brain damage, and even death.
Causes of Heatstroke in Dogs
Dogs are far more prone to heatstroke than humans. Even if you’re handling the heat well, your dog may not be — because dogs can’t cool themselves as effectively as people.
Dogs have sweat glands only on their paw pads. These glands help minimally. Instead, dogs rely primarily on panting to cool themselves. When panting alone cannot keep up with body heat production, heatstroke can develop quickly.
Types of Heatstroke in Dogs
Heatstroke is commonly linked to hot weather, but several situations can trigger it.
Situations that increase heatstroke risk include:
- Confinement in a parked car or unventilated space
- High temperatures (especially with humidity)
- Lack of shade
- Limited access to water
- Excessive exercise in hot weather
- Puppies and senior dogs
- Obesity
- Underlying health issues
- Brachycephalic breeds (Pugs, French Bulldogs, etc.)
- Large breeds (Chow Chow, Newfoundland, Saint Bernard, etc.)
Dog Heatstroke Symptoms
Recognizing heatstroke early can save your dog’s life. Below are the warning signs.
Common symptoms include:
- Excessive panting and drooling
- Dry, red gums and tongue
- Weakness or lethargy
- Loss of balance
When heat exposure continues, signs of shock appear: pale/blue gums, irregular heart rate, vomiting, diarrhea, muscle tremors, and unconsciousness. If these develop, seek emergency veterinary care immediately.
What to Do If Your Dog Experiences Heatstroke
If you suspect heatstroke, act immediately.
1. Move your dog to shade or an air-conditioned area.
2. Apply cool (not cold) water to the belly, neck, and legs. Avoid ice-cold water and avoid full-body submersion.
Offer cool drinking water, but do not force it. Call your veterinarian immediately for instructions. Head to the nearest emergency clinic if symptoms worsen or do not improve rapidly.
Preventing Heatstroke in Dogs
Prevention is the most effective way to keep your dog safe.
1. Never leave your dog in a parked car.
Even mild outdoor temperatures can cause deadly car temperatures within minutes.
2. Provide shade and fresh water.
Ensure constant access to both.
3. Avoid hot surfaces.
Asphalt and sand can burn paws and raise body temperature quickly.
4. Limit exercise during peak heat.
Opt for morning or evening walks.
Conclusion
Heatstroke in dogs is dangerous, but preventable. By recognizing triggers and early symptoms — and acting quickly — you can protect your dog throughout the summer months.
If you suspect heatstroke, contact your veterinarian right away.

Temperatures above 80°F (26°C), especially with humidity, can be risky depending on breed and activity level.
Is heatstroke more common in certain breeds?
Yes — brachycephalic breeds and large breeds have a higher risk.
What should I NOT do if my dog has heatstroke?

Comment
It infuriates me to see peopIe gliding along on their bicycles on a warm or hot day (even a cool day, if it’s for too long), with a dog on a leash made to run beside them. I saw a couple doing that to a husky (!!!) yesterday while walking my dog in the shade, but anytime I say anything, no matter how nicely I try to tell them, the people just get annoyed. How dare I question their judgement !
