Heat Stroke in Dogs: Symptoms, Emergency Steps, and How to Cool a Dog Down

Heat stroke kills dogs, and it does it fast. A dog can go from panting hard to collapsing in well under an hour on a hot day, and by the time the obvious signs show up the internal damage has already started. Knowing what overheating looks like early, and knowing what to do in the first few minutes, is the difference between a scare and an emergency. Here is how to recognize heat exhaustion and heat stroke in a dog, what to do right away, and which dogs are most at risk.

What Causes Heat Stroke in Dogs?

Dogs don’t sweat, and panting is their only mechanism for cooling down. Heat stroke happens when their panting can’t keep up, and their body temperature rises above 39°F. Playing fetch on a hot day can be enough to cause a heat stroke. Especially for older and less active dogs, simply running, playing, or even walking in the heat can lead to overheating.

Most pet owners know you shouldn’t leave your dog in the car. But anywhere that does not have an adequate airflow can cause your dog to get dangerously overheated. Fans and open windows are essential to keep your dog comfortable.

Which Dogs Are Most at Risk of Heat Stroke?

Flat faced breeds like Boston Terriers, Boxers, Lhasa apsos, Pugs, and Shih tzus are more likely to suffer from heat stroke. Their short noses make it harder for them to get enough air to cool themselves down. If it’s hot out, these brachycephalic breeds should only be outside for 10 to 15 minutes.

How to Prevent Heat Stroke in Dogs

There are a few easy steps you can take to keep your dog safe in the summer months:

1. Make sure your dog has plenty of water at all times. Bring some with you and make sure to fill up your pup’s water dish whenever you stop to fill up your own water bottle.
2. Don’t leave your dog in the car, even with the windows rolled down. The temperature inside the car gets much hotter than the outside in just a few minutes. Even if it’s just 70°F, inside the car can quickly reach 115°F.
3. Don’t go for walks, runs, or hikes during the hottest part of the day. Plan your walks early in the morning or for the sunset.

Symptoms of Heat Stroke in Dogs

Look out for the following symptoms of heat stroke:

• Heavy panting over a long period of time.
• Lots of drooling.
• Red tongue and gums.
• Weakness and wobbly, unsteady walking
• Vomiting and diarrhea.
• In severe cases, collapse.

How to Cool Down an Overheated Dog

Try to lower their body temperature slowly. Give them cool, not cold water. Cold water could send them into shock. Pour cool water over their neck and chest. Do not place wet towels over their body, as their body temperature rises, the towels will trap the heat.  Place them in a room with lots of cool air circulation. Always call your vet for further recommendations.
