Heat Stroke in Pets: What Every Owner Needs to Know This Summer

As temperatures soar during the warmer months, our pets are at a greater risk for heat stroke — a potentially life-threatening condition that can escalate quickly without immediate action. Unlike humans, dogs and cats don’t sweat to cool themselves. They rely primarily on panting, which makes them far more vulnerable to overheating. At Vets to Pets Mobile Veterinary Care, we believe prevention and early recognition are the keys to protecting your pets from heat-related emergencies.

What Is Heat Stroke?

Heat stroke, or hyperthermia, occurs when a pet’s body temperature rises above a safe range and they can no longer cool themselves efficiently. For dogs and cats, a body temperature over 104°F (40°C) is considered abnormal. At 106°F (41°C) or higher, organ damage and even death can occur without urgent care.

Pets Most at Risk

While any pet can suffer from heat stroke, some are more susceptible:

Brachycephalic breeds (like Bulldogs, Pugs, and Persians)
Older pets
Overweight animals
Pets with heart or respiratory issues
Thick-coated or long-haired breeds

Common Causes of Heat Stroke

Being left in a parked car, even for a few minutes
Excessive exercise during peak heat hours
Lack of access to shade or fresh water
Being kept in poorly ventilated spaces
Hot asphalt or pavement walks (compounds heat exposure)

Warning Signs of Heat Stroke in Pets

Act fast if you notice any of the following symptoms:

Excessive or rapid panting
Drooling or thick, sticky saliva
Bright red or pale gums and tongue
Vomiting or diarrhea (possibly with blood)
Weakness, staggering, or collapse
Rapid heartbeat
Glazed eyes
Seizures or unconsciousness (in severe cases)

What to Do If You Suspect Heat Stroke

Move your pet to a shaded, cool area immediately.
Cool them gradually: Use cool (not cold) water on their body or apply cool, wet towels to their neck, belly, and paws.
Offer small amounts of cool water, but don’t force them to drink.
Do NOT use ice — it can cause shock or constrict blood vessels.
Call your veterinarian or emergency clinic right away. Even if your pet seems to improve, internal damage may still occur.

How to Prevent Heat Stroke

Never leave pets in parked cars — even with the windows cracked.
Walk dogs early in the morning or after sunset.
Provide plenty of fresh, cool water at all times.
Make sure your pet has access to shade or air conditioning.
Limit exercise on hot or humid days.
Consider a cooling vest or mat for extra relief during heat waves.

Heat stroke can be sudden, severe, and deadly — but it’s almost always preventable. Knowing the signs and acting quickly can save your pet’s life. This summer, prioritize shade, hydration, and safe temperatures during all your outdoor adventures.
