Heatstroke Warning 2025: How Hot Is Too Hot for Your Dog?
With forecasters predicting an earlier-than-usual heatwave, veterinarians are sounding the alarm: heatstroke in dogs can start at just 19 °C / 66 °F—well before the pavement feels scorching.
Why Dogs Overheat Faster Than We Do
Dogs cool themselves mainly by panting and a little through the pads of their feet. High humidity or restricted airflow makes panting less effective, quickly pushing a dog’s internal temperature past the danger zone. Brachycephalic breeds (Pugs, Bulldogs), seniors, overweight dogs, and those with heart or respiratory disease are at highest risk.
Know the “Too-Hot-to-Trot” Temperature
Experts recommend:
- Below 68 °F / 20 °C: Generally safe for most dogs.
- 68 – 77 °F / 20 – 25 °C: Use caution and monitor brachycephalic or at-risk dogs.
- Above 77 °F / 25 °C: Walk only at dawn/dusk and stick to shade.
- Above 86 °F / 30 °C: Skip the walk—indoor enrichment is safer.
Early Signs of Heatstroke
Watch for heavy panting, thick drool, bright-red or pale gums, wobbliness, vomiting, or sudden collapse. At a rectal temperature of 105 °F (40.5 °C) or higher, heatstroke becomes life-threatening and your dog needs immediate vet care.
Emergency Cool-Down Steps
If you suspect heatstroke:
- Move your dog into shade or air-conditioning.
- Wet the coat with cool, not cold water—focus on belly, paws, and armpits.
- Set a fan blowing over the damp fur.
- Offer small sips of water.
- Head to the nearest emergency vet—heatstroke can cause organ failure within minutes.
Pro Tips for Staying Cool All Summer
- Walk before 9 a.m. or after sunset.
- Stick to grass trails; asphalt can reach 140 °F when air temps hit 95 °F.
- Pack a collapsible water bowl on every outing.
- Use cooling vests or bandanas on brachycephalic breeds.
- Never leave a dog in a parked car—even with windows cracked.
Bottom Line
Skipping a walk beats risking a dog’s life. Check the forecast, touch the pavement, and keep a close eye on any signs of overheating. A few simple precautions can turn a scorching day into safe summer fun.
