Heatstroke in dogs and cats: symptoms, prevention, and treatment
Heatstroke is a serious and potentially life-threatening condition that affects both dogs and cats. It occurs when their body temperature rises to dangerous levels, usually as a result of prolonged exposure to high temperatures, humidity, or inadequate ventilation. Unlike humans, pets cannot cool themselves effectively through sweating, making them more susceptible to overheating. At Animal Mama Hospital, we are committed to educating pet owners about heatstroke and providing the best care for pets in need.

What is heatstroke in pets?
Heatstroke, also known as hyperthermia, happens when a pet’s body temperature exceeds the normal range and cannot regulate itself. In dogs, this typically means a temperature above 39.5°C (103°F), and in cats, above 39°C (102.5°F). Severe heat stroke can lead to organ damage, seizures, or even death.
Causes of heatstroke
Hot Weather & Direct Sun Exposure: High temperatures, especially during summer, pose a significant risk.
Poor Ventilation: Leaving pets in parked cars or small enclosed spaces without ventilation is a common cause.
Excessive Exercise: Overexertion, especially during hot weather, can trigger heatstroke.
Underlying Conditions: Pets with obesity, heart disease, or respiratory issues are more vulnerable.
Brachycephalic Breeds: Breeds like Bulldogs, Pugs, and Persians are more prone to heatstroke due to their short noses, which make breathing less efficient.
Symptoms of heatstroke in dogs and cats
Recognizing the early signs of heatstroke is crucial to saving your pet’s life:
In Dogs:
- Excessive panting or difficulty breathing
- Drooling
- Bright red or pale gums
- Vomiting or diarrhea (sometimes with blood)
- Weakness, collapse, or seizures
- Elevated heart rate
In Cats:
- Rapid breathing or open-mouth breathing
- Lethargy or inability to move
- Restlessness or distress
- Bright red tongue or gums
- Vomiting or drooling
- Tremors or seizures
What to do if you suspect heatstroke
If you notice signs of heatstroke, act immediately:
- Move your pet to a cool area: Get them out of direct sunlight or hot areas.
- Cool them down gradually: Use cool (never iced or cold) water to wet their body, focusing on the neck, belly, and paw pads. Avoid ice water, as it can cause shock.
- Provide water: Offer small amounts of cool water to drink but do not force it.
- Seek veterinary care: Heatstroke is a medical emergency. You can always contact your veterinarian or bring your pet to Animal Mama Hospital immediately.
Preventing heatstroke
- Keep pets indoors: During the hottest parts of the day, ensure your pets stay in a cool, shaded area.
- Hydration is key: Always provide access to fresh, cool water.
- Limit exercise: Avoid walks or playtime during peak heat hours. Opt for early morning or late evening outings.
- Never leave pets in cars: Temperatures can rise dangerously high in minutes, even with windows cracked.
- Grooming: Regular grooming helps remove excess fur and keeps pets cooler, especially for long-haired breeds. Do NOT shave the dogs, as the fur helps dog regulate their body temperature.

FAQ about heatstroke in pets
- Can cats get heatstroke, or is it just a dog problem?
Yes, cats can also suffer from heatstroke, though it’s less common. Cats tend to hide their discomfort, making it harder to recognize the signs.
- What temperature is dangerous for pets?
For dogs, a temperature above 39.5°C (103°F) is dangerous, while for cats, it’s above 39°C (102.5°F).
- Can I use ice water to cool my pet during heatstroke?
No! Avoid using ice water as it can cause blood vessels to constrict, slowing the cooling process and causing shock. Use cool, tap water instead.
- Are some pets more prone to heatstroke?
Yes, brachycephalic breeds, elderly pets, overweight animals, and those with underlying health issues are more susceptible.
- How long does it take for a pet to recover from heatstroke?
Recovery time varies based on the severity of the heatstroke and the pet’s overall health. Some may recover in a few days, while others may need weeks of care.
- Can heatstroke cause long-term damage?
Yes, severe cases of heatstroke can lead to organ damage, especially to the brain, heart, and kidneys, which may have lasting effects.
