Heatstroke in dogs and cats: Prevention and first aid
Wednesday, June 22nd, 2026
Care and advice
With the arrival of summer, high temperatures can cause heatstroke in our pets. Keep in mind that animals are much more sensitive to heat than humans. Because they do not have sweat glands, they cannot regulate their body temperature through perspiration. Dogs release heat by panting and through sweat expelled from the pads of their feet and isolated areas with little hair, such as their belly. Cats try to maintain a stable temperature by licking themselves and keeping their fur smooth. In this way, the saliva deposited on their fur evaporates, reducing their body heat.
How to prevent heatstroke?
To prevent your best friend from suffering heatstroke, remember:
-Give them small amounts of water frequently to prevent dehydration.
-Never leave your dog inside a car.
-Avoid walking them during the hottest part of the day.
-Avoid leaving them exposed to the sun. Always look for a shady spot. -In summer, it is best to feed your dog in the evening after you have eaten. -During walks, outings, excursions, etc.,it is important to bring plenty of water in a portable bottle and keep them hydrated at all times.-When traveling by car, avoid carrying it in the trunk.
How to detect the symptoms of heatstroke in our pet?
What should we do if our animal is suffering from heatstroke?
First of all, it is important to know that you cannot lower their temperature suddenly, because this will cause hypothermia. The temperature must be lowered gradually and the animal must be rehydrated and replenished with the sugar and salts it has lost.
1. Take your pet to a veterinary clinic immediately. During the journey, you should:
- Moisten (without wrapping or covering) the neck and head first with cloths dipped in lukewarm water or a water spray bottle.- NEVER cover them with wet towels. - Place an ice cube on the bridge of the nose, groin, and armpits. - Moisten their mouth, without forcing them to drink or letting them drink too much.
2. If the animal cannot be taken to a veterinary clinic immediately, take it to a cool place and follow these steps:
- Immerse it in water at around 20°C or spray it with water at that temperature until its breathing returns to normal.- Moisten (without wrapping or covering) primarily the neck and head using cloths dipped in lukewarm water or a water spray.- NEVER cover them with wet towels. If possible, use a fan to help. - Place an ice cube on the bridge of the nose, in the groin, and in the armpits.- Moisten their mouth, without forcing them to drink, and without letting them drink too much. - When their breathing is normal, keep them on a damp towel. - Take them to the vet as soon as possible and explain everything you have done. It is essential that a veterinarian monitors and observes the animal to see how it progresses. Normal breathing does not eliminate brain damage and other sequelae of this severe shock, so we insist that you take the animal to the veterinarian as soon as possible.
