How Hot Is Too Hot for My Dog?
When summer temperatures soar, pet parents often ask, “How hot is too hot for my dog?” Dogs rely on us to make safe choices in extreme weather, and what feels warm to us can be dangerously hot for them. With no way to sweat like humans, dogs primarily cool down through panting and paw pads, putting them at a higher risk of heat exhaustion, dehydration, and heatstroke.

How Heat Affects Dogs
Some dogs are more heat-sensitive than others:
- Brachycephalic breeds (like French Bulldogs, Pugs, and Boxers)
- Senior dogs and puppies
- Overweight dogs
- Dogs with underlying medical conditions
They can overheat quickly, even in what feels like mild weather.
Temperature Guide: When Is It Too Hot?
Use this temperature chart as a general guide for safe outdoor time:
- 15°C (59°F) – No risk. Enjoy the outdoors!
- 18-21°C (64-70°F) – Still safe. Monitor hydration.
- 23°C (73°F) – Risk begins to develop for sensitive dogs.
- 26-29°C (79-84°F) – Avoid long walks or play; risk of heatstroke increases.
- 32°C (90°F) – Dangerous for overweight dogs.
- 35°C (95°F) – Dangerous for flat-faced breeds.
- 37°C (98.6°F) – Dangerous for puppies and elderly dogs.
- 40-43°C+ (104-109°F) – Life-threatening heat even with shade or water.
To test pavement temperature, press the back of your hand to the ground for 7 seconds. If it’s too hot for you, it’s too hot for your dog’s paws.









Hydration Matters
Dogs lose moisture quickly in hot weather, and without proper hydration, they are at higher risk of overheating. Help them stay cool by:
- Offering constant access to clean, cool water
- Providing hydration-boosting snacks like cucumbers, watermelon, and bone broth ice cubes
- Using a lick mat with plain Greek yogurt as a cooling treat

Signs of Heatstroke in Dogs
Recognizing heatstroke early can save your dog’s life. Watch for:
- Heavy or rapid panting that doesn’t subside
- Thick, sticky drool
- Red or pale gums
- Vomiting or diarrhea
- Glazed eyes or confusion
- Weakness, collapsing, or seizures

If you notice these symptoms:
- Move your dog to shade or a cool room
- Offer small amounts of cool water
- Contact your vet or an emergency clinic immediately
Keep Walks and Playtime Safe
- Avoid mid-day walks. Choose early morning or late evening.
- Stick to grass and shaded areas
- Shorten play sessions in high temps
- Never leave your dog in a parked car. Even with windows cracked, it can become deadly within 10 minutes.
