Heatstroke in Dogs: Warning Signs, Prevention, and What to Do in an Emergency

Unlike humans, dogs can't sweat to cool themselves down — they rely almost entirely on panting and, to a lesser degree, releasing heat through their paw pads. That makes them far more vulnerable to heatstroke than most owners realize, and it can escalate from mild discomfort to a life-threatening emergency in a matter of minutes.

• Flat-faced (brachycephalic) breeds like Bulldogs, Pugs, and Boxers
• Senior dogs and puppies
• Overweight dogs
• Dogs with thick or dark coats
• Dogs with heart or respiratory conditions

• Heavy, rapid panting that doesn't slow down
• Excessive drooling
• Bright red or pale gums
• Lethargy or reluctance to move
• Stumbling or loss of coordination

• Vomiting or diarrhea
• Seizures
• Collapse
• Body temperature above 104°F

If you see any of these signs, this is a medical emergency — head to the nearest vet immediately, even while beginning cooling steps in the car.

1. Never leave a dog in a parked car. Even with windows cracked, car interiors can reach dangerous temperatures within minutes, even on mild days.
2. Walk during cooler hours. Early morning or evening walks avoid peak heat and hot pavement, which can burn paw pads.
3. Always provide access to fresh water and shade, whether at home, in the yard, or on outings.
4. Know your dog's limits. High-energy breeds may want to keep playing past the point of safety — you have to make the call to stop.
5. Watch humidity, not just temperature. High humidity makes it harder for panting to cool a dog down effectively, even at moderate temperatures.

1. Move your dog to shade or air conditioning immediately.
2. Apply cool (not ice-cold) water to their body, focusing on the belly, paws, and neck.
3. Offer small amounts of water if they're able to drink.
4. Get to a veterinarian right away — even dogs who seem to recover can have serious internal damage that isn't visible.

Heat safety isn't just a summer issue — it's a year-round awareness that can genuinely save your dog's life.
