As temperatures rise, so does the risk of heatstroke — a dangerous and potentially life-threatening condition that can severely impact the health of our pets. Unlike humans, dogs and cats have limited ways of regulating their body temperature and are far more vulnerable to overheating.
Below, we explain how to recognize heatstroke, the critical first steps in treatment, and what you can do to prevent it.
What Is Heatstroke?
Heatstroke (also known as hyperthermia) occurs when the body temperature rises to dangerously high levels, typically above 40–41°C (104–105.8°F). If not treated immediately, it can lead to organ failure and death.
Which Pets Are Most at Risk?
Although any animal can suffer from heatstroke, certain groups are more vulnerable:
- Dogs and cats with long or thick coats
- Brachycephalic breeds (e.g., French Bulldogs, Pekingese, Persian cats)
- Senior pets, puppies, and kittens
- Animals with heart, respiratory problems, or obesity
- Pets exposed to enclosed, hot environments (such as cars)
Signs of Heatstroke
Early recognition of symptoms can save lives. Watch for the following:
In dogs:
- Rapid, heavy panting
- Excessive drooling
- Severe weakness or inability to stand
- Red or purple gums and tongue
- Vomiting or diarrhea (possibly with blood)
- Loss of consciousness or seizures
In cats:
- Loss of appetite, weakness, lethargy
- Open-mouth breathing with rapid respiration
- Excessive grooming or growling
- High body temperature (if measured)
- Reduced responsiveness or fainting
First Aid for Heatstroke
If you suspect heatstroke, act quickly:
- Move the animal to a cool, shaded area.
- Cool the body with lukewarm — not cold — water using cloths or a gentle shower.
- Use a fan or allow air to circulate around the pet.
- Do not cover them with towels, as this can trap heat.
- Offer small amounts of water if the pet is able to drink.
Call your veterinarian immediately or go to the clinic — heatstroke is an emergency, and professional care is critical.
Prevention: The Key to Protecting Your Pet
- Never leave your pet in a car, not even for a few minutes.
- Limit physical activity during peak heat hours (12:00–18:00).
- Ensure constant access to fresh water and shade.
- Opt for walks early in the morning or late in the evening.
- Use a fan or air conditioning, especially in poorly ventilated indoor spaces.
- Talk to your veterinarian about grooming or other tailored recommendations if your pet has a long coat.
In Summary
Heatstroke is a serious but entirely preventable condition. Awareness and proper information are the most powerful tools to protect your four-legged friend. If you have even the slightest suspicion, don’t hesitate — act immediately and contact your veterinarian.
