Preventing Heatstroke in Dogs: What to Do When It's Hot

Heatstroke is one of the most common — and most preventable — summer emergencies in dogs. It can happen faster than you think, and knowing what to look for could save your dog’s life.

What is heatstroke?

Heatstroke occurs when a dog’s body temperature rises above 104 °F and they can no longer cool themselves down. A normal dog temperature is around 101–102.5 °F. Once it climbs past 106 °F, organ damage can begin within minutes.

What to do if you suspect heatstroke

1. Move your dog to a shaded or air-conditioned area immediately.
2. Apply cool (not ice-cold) water to their neck, armpits, and belly. Wet towels work, but replace them often — they trap heat quickly.
3. Offer small sips of water — don’t force them to drink.
4. Point a fan at them if one is available.
5. Get to a vet as soon as possible, even if your dog seems to be recovering. Internal damage isn’t always visible.

Prevention is everything

• • Exercise in the early morning or evening — skip midday outings on hot days.
• • Always provide access to shade and fresh water.
• • Never leave your dog in a parked car.
• • Watch brachycephalic (short-nosed) breeds and overweight dogs extra closely — they’re at higher risk.
• • Know your dog. If they’re slowing down, panting hard, or seeking shade, it’s time to stop.

A note about puppies

Young puppies are especially vulnerable because their bodies don’t regulate temperature as efficiently as adults. Keep play sessions short, provide plenty of water breaks, and trust your instincts — if it feels too hot for you, it’s definitely too hot for your pup. 🐾
