How Hot Is Too Hot for Dogs to Be Outside This Summer?
Summer brings longer days, sunny skies, and more opportunities to explore the outdoors with your dog. But as temperatures rise, so do the risks. Knowing how hot is too hot for dogs to be outside is essential to keeping your pup safe and healthy during warm-weather adventures.
Whether you're hiking, camping, or just spending time in the backyard, understanding heat safety for dogs could save their life.
What Temperature Is Too Hot for Dogs?
While each dog has different heat tolerance based on breed, size, and health, here are some general guidelines:
- 85°F (29°C) or higher is when dogs start to experience heat-related stress, especially with physical activity.
- 90°F (32°C) is when risk levels increase significantly, even for healthy, active dogs.
- 100°F (38°C) and above is dangerous for nearly all dogs, regardless of breed or condition.
Humidity makes the heat even more dangerous because it reduces your dog’s ability to cool down through panting.
Breeds Most at Risk in Hot Weather
Some dogs are more susceptible to heat exhaustion and heatstroke, including:
- Brachycephalic breeds (Bulldogs, Pugs, Boxers)
- Double-coated breeds (Huskies, Malamutes, Newfoundlands)
- Senior dogs and puppies
- Overweight dogs
- Dogs with existing respiratory or heart conditions
Even breeds that thrive outdoors, like Retrievers or Shepherds, can overheat in extreme heat if not properly cooled and hydrated.
Tips to Keep Your Dog Safe in Hot Weather
If you're heading outside with your dog this summer, take these precautions to keep them cool and comfortable:
-
Avoid mid-day walks between 10 a.m. and 4 p.m.
-
Stick to shaded trails or areas with tree cover.
-
Bring plenty of fresh water and offer frequent breaks.
-
Use cooling gear such as vests, bandanas, or mats.
-
Avoid pavement or hot sand—use the “5-second rule” for paw safety.
-
Limit strenuous exercise and play.
-
Never leave your dog in a parked car, even with the windows cracked.
-
Offer frozen treats or ice cubes as a refreshing snack.
-
Use a misting fan or portable cooling device if staying out longer.
-
Know the signs of heat exhaustion and take immediate action if needed.
Signs of Overheating and Heatstroke in Dogs
Your dog can't tell you they're overheating, so it's important to know the warning signs:
- Excessive panting or drooling
- Bright red or pale gums
- Lethargy or stumbling
- Vomiting or diarrhea
- Collapse or unresponsiveness
If your dog shows any of these signs, move them to a cool place, provide water (don’t force it), wet their body with cool—not cold—water, and contact a veterinarian immediately.
Best Times and Places to Exercise Dogs in Summer
To enjoy the outdoors safely with your dog:
- Go out early in the morning or after sunset when it’s cooler.
- Choose higher elevation hikes or shaded forest trails.
- Plan water activities like swimming or paddleboarding.
- Keep outings short and watch for signs of fatigue.
Recommended Summer Gear for Dogs
Investing in a few quality gear items can make summer outings safer for your dog:
- Cooling vests and bandanas
- Collapsible water bowls or hydration packs
- Dog-safe sunscreen (especially for light-colored or thin-coated dogs)
- Lightweight, breathable harnesses
- Booties or paw wax to protect from hot surfaces
