Hot Weather Dangerous for Pets ─ How to Keep Them Safe

July 16, 2025

Don’t leave your pet in a hot vehicle, even for a few minutes. The inside temperature of the car can quickly reach 120 degrees even with the windows cracked open.

Summer’s extremely hot weather has arrived, a situation that can be dangerous for your family pets. The American Red Cross has steps you can take to help ensure your four-legged friends stay safe this summer.

HEAT STROKE Animals can suffer heat stroke, a common problem for pets in warmer weather. Dogs with short noses or snouts, like the boxer or bulldog, are especially prone to heat stroke, along with overweight pets, those with extremely thick fur coats or any pet with upper respiratory problems such as laryngeal paralysis or collapsing trachea.

Some signs of heat stroke in your pet are:

Heavy panting and unable to calm down, even when lying down
Brick red gum color
Fast pulse rate
Unable to get up

If you suspect your pet has heat stroke, take their temperature rectally. If the temperature is above 104 degrees, cool the animal down. The easiest way to do this is by using the water hose. Stop cooling the animal when the temperature reaches 103 degrees. Bring your pet to the veterinarian as soon as possible as heat stroke can lead to severe organ dysfunction and damage.

STEPS TO KEEP YOUR PET AT THEIR BEST:

Give your pet plenty of exercise.
Make sure your pet has plenty of fresh, cool water and shade.
Make sure your pet has yearly checkups and is up to date on vaccines, especially mandated rabies vaccines.
Keep dogs on leashes outside – another animal may be too much temptation.
Know how to perform CPR and provide basic first aid until veterinary care is available.
