Heatstroke in pets: How to prevent it and spot the signs

When temperatures rise, you probably often think about drinking more water, finding shade or taking it easier during outdoor activities. The same goes for your pets. In fact, it can be even more important for them. Dogs, cats and many other companion animals do not regulate their body temperature the same way humans do. They usually sweat much less and rely mainly on breathing to help cool themselves down.

The problem is that this cooling process can become much harder when the heat is intense, the air is humid or an animal is exposed to the sun for too long. Heatstroke can then occur and quickly become a veterinary emergency. The good news? Knowing the right precautions can help reduce the risk.

What is heatstroke?

Heatstroke happens when an animal’s body temperature rises too high and their body can no longer bring it back down effectively. Their system then comes under stress. Without quick action, this can lead to serious complications.

It is not only a risk on official heatwave days. A hot, humid day, a walk in full sun, a poorly ventilated balcony, too much physical effort or even a few minutes in a parked car can all increase the risk of heatstroke.

Although dogs are often the first pets that come to mind, cats can also suffer from heatstroke. Their signs may be more subtle, which makes it even more important to pay attention to changes in their behaviour.

Some animals are more vulnerable

Any animal can be affected by heat, but some are at higher risk. This includes young animals, senior pets, animals carrying extra weight, and those with respiratory or heart conditions.

Flat-faced breeds, such as bulldogs and some cats with shorter noses, may also have more difficulty cooling down. Their breathing is sometimes less efficient, making them more sensitive to high temperatures. Pets with thick coats may also be more uncomfortable when the temperature climbs.

Signs of heatstroke in animals

An animal suffering from heat may not always show obvious signs. That is why it is important to watch for changes in behaviour or appearance.

Possible signs of heatstroke include rapid breathing, unusual fatigue, sudden weakness, heavy drooling, vomiting or diarrhea. Some animals may seem disoriented, restless or have trouble walking. Their gums may also become very red or, on the contrary, very pale. In more severe cases, the animal may collapse or lose consciousness. This is an emergency.

What should you do if you suspect your pet has heatstroke?

If you think your pet may be suffering from heatstroke, the first step is to move them to a cool, shaded or well-ventilated place. When possible, bring them into an air-conditioned space or place them near a fan.

You can offer fresh water, but do not force them to drink. You can also help cool your pet gradually by applying cool or lukewarm water to their coat. Avoid ice-cold water, which is not recommended in this situation.

Then, contact a veterinarian or animal health professional right away. Even if your pet seems better after a few minutes, it is best to get professional advice, as some complications may not be visible immediately.

Simple habits that help prevent heatstroke in animals

Prevention comes down to a few easy habits. Make sure your pet always has access to fresh water, especially on hot days. Outdoors, choose shaded, well-ventilated areas whenever possible.

Avoid walks during the hottest hours of the day. Early morning or evening outings are often much more comfortable. During heatwaves, adjust the intensity and length of activities. Also, pay attention to surfaces: asphalt, sidewalks and some patios can become extremely hot and hurt your pet. If the ground is too hot for your hand, it is probably too hot for your pet’s paws.

Finally, never leave an animal alone in a car, even for a few minutes and even with the windows slightly open. The temperature inside a vehicle can rise very quickly.

A safer summer for your four-legged friend

With the right precautions, you can enjoy summer while helping your pet stay safe. Adjusting outings, offering fresh water, avoiding overly hot environments and watching for unusual signs can make a real difference to their well-being.

Key takeaway

Heatstroke in animals can progress quickly. If your pet seems unusually tired, is breathing with difficulty or shows concerning signs after heat exposure, do not wait. Contact an animal health professional right away.
