Keep Your Cool: How to Prevent and Treat Heat Stroke in Pets

Summer fun is best shared with our furry friends—but rising temperatures, especially in Florida, can quickly turn dangerous for pets. Heat stroke is a life-threatening emergency that can affect dogs and cats when their body temperature soars above safe levels.
 
As veterinarians, we see far too many cases that could have been prevented with a little awareness and planning. Here’s what every pet owner needs to know about heat stroke: how to prevent it, spot the warning signs, and take action fast.

What Is Heat Stroke in Pets?

 
Heat stroke (or hyperthermia) occurs when a pet’s body overheats, typically reaching a core temperature above 104°F (40°C). Pets in Florida are especially vulnerable to heat stroke due to our hot, humid climate.
 
Unlike humans, dogs and cats don’t sweat to cool off; they rely on panting and limited sweat glands in their paws, which makes them more vulnerable in hot, humid weather.

Risk Factors

 
Any pet can suffer from heat stroke, but some are at higher risk:
 
  • Brachycephalic breeds (like Bulldogs, Pugs, and Persians)
  • Overweight pets
  • Senior animals
  • Pets with heart or respiratory conditions
  • Thick-coated or dark-colored breeds
  • Pets left in hot cars or poorly ventilated areas

Warning Signs of Heat Stroke in Pets

 
Early detection can save lives. Watch for these signs:
 
  • Excessive panting or drooling
  • Bright red or pale gums
  • Weakness or collapse
  • Vomiting or diarrhea (sometimes with blood)
  • Glazed eyes or confusion
  • Seizures or unconsciousness in severe cases

What to Do If You Suspect Your Pet Has Heat Stroke

 

Act fast and stay calm:

 

  1. Move your pet to a cooler area—preferably indoors or in the shade.
  2. Apply a cool, damp cloth to your pet’s belly or dampen their coat with cool (not ice-cold) water, especially on the neck, armpits, and paw pads. This can help lower their body temperature and buy precious time.
  3. Use a fan or air conditioning to aid cooling.
  4. Offer small amounts of cool water to drink, but don’t force it.
  5. Take your pet to the nearest veterinary clinic immediately. Time is critical, and even if your pet appears better, internal damage can still be occurring.
  6. Call the clinic on your way in so the veterinary team can be ready and waiting when you arrive.

Prevention Tips: Keeping Pets Safe in the Heat

 

  • Never leave pets in a parked car, even for a minute—temperatures can soar to deadly levels in moments.
  • Walk dogs early in the morning or late in the evening to avoid the hottest parts of the day.
  • Keep pets well-hydrated and provide access to shade.
  • Avoid hot pavement, which can burn paw pads.
  • Use cooling mats, fans, or kiddie pools for enrichment and relief.
  • Know your pet’s limits. If they’re panting heavily or slowing down, take a break.

Heat Stroke in Pets: Final Thoughts

 
Heat stroke is preventable—but it can become fatal in a matter of minutes. As a pet parent, your awareness and quick action are the best defenses. If you suspect heat stroke, apply a cool, damp cloth to your pet’s belly or wet their coat with cool water while you head immediately to the vet—and be sure to call ahead so our veterinary team can prepare.
