As the temperature climbs, we all want to enjoy outdoor fun with our furry friends. But dogs don’t sweat like we do, so it’s crucial to know when it’s too hot for them and how to spot signs of overheating early.

Why Heat Is Risky for Dogs

Dogs regulate heat mainly by panting and through their paw pads, but they’re more vulnerable than humans to heat stress. High temperatures can quickly lead to heat exhaustion or heat stroke, which can be life-threatening.

According to the American Veterinary Medical Association (AVMA), dogs exposed to hot weather without proper care risk dehydration, heat stroke, organ damage, and even death. Understanding the signs can save your pup’s life.

What Temperature Is Too Hot for Dogs?

While every dog is different, temperatures above 85°F (29°C) are generally considered risky, especially with high humidity. Small breeds, brachycephalic dogs (like French Bulldogs, English Bulldogs, Pugs, Boston Terriers, Boxers, and Shih Tzus), older dogs, puppies, and overweight dogs are even more sensitive.

Even 70°F (21°C) with high humidity can be dangerous during vigorous activity.

How to Tell If Your Dog Is Overheating: Key Signs to Watch For

1. Excessive Panting or Difficulty Breathing
Panting is normal, but if it’s relentless, labored, or your dog’s gums turn bright red, that’s a warning sign. Research from the Journal of Veterinary Emergency and Critical Care highlights that abnormal respiratory effort is a critical early indicator of heat distress.

2. Drooling More Than Usual
Heat can cause increased saliva production. If the drool is excessive and thick, it can signal overheating.

3. Bright Red or Pale Gums and Tongue
Healthy gums are usually pink. Red, pale, or bluish gums can mean poor oxygen circulation due to heat stress.

4. Weakness, Dizziness, or Staggering
If your dog seems unsteady or weak, they may be suffering from heat exhaustion or heat stroke.

5. Vomiting or Diarrhea
Digestive upset can happen as the body struggles with overheating.

6. High Body Temperature
A dog’s normal temperature ranges from 101°F to 102.5°F. Temperatures above 104°F are dangerous. Use a rectal thermometer if you suspect overheating.

What To Do If You Think Your Dog Is Overheating

• Move them to a cool, shaded area immediately
• Offer small amounts of water, but don’t force it
• Use cool (not ice-cold) water to wet their body or apply cool, damp towels
• Avoid ice baths; rapid cooling can cause shock
• Contact your vet immediately if symptoms worsen or don’t improve quickly

Prevention Tips to Keep Your Dog Safe and Cool in Hot Weather

1. Schedule Walks During Cooler Hours
Avoid walks and playtime between 10 a.m. and 4 p.m., when the sun is strongest. Early mornings and evenings are much safer for your dog to be active.

2. Test the Pavement Before You Walk
Place the back of your hand on the pavement for 7 seconds. If it’s too hot for your hand, it’s too hot for your dog’s paws. Opt for grassy areas or shaded sidewalks whenever possible.

3. Hydrate, Hydrate, Hydrate
Carry a portable water bottle and collapsible bowl on walks and outings. Offer water frequently, especially after any activity, to prevent dehydration.

4. Create a Cool Resting Spot
Set up a shady spot with a cooling mat or damp towel where your dog can lie down and lower their body temperature.

5. Use Cooling Gear
Try breathable harnesses, cooling bandanas soaked in cold water, or even a spray bottle with water to mist your dog during breaks.

6. Never Leave Your Dog in a Parked Car
Even with windows cracked, temperatures inside a car can soar within minutes, putting your dog at serious risk of heat stroke.

7. Keep Grooming Regular
Regular brushing helps remove excess fur that can trap heat. But don’t shave your dog down to the skin—it can actually increase sunburn risk!

8. Know Your Dog’s Limits
If your dog belongs to a brachycephalic breed like a French Bulldog or Pug, limit exertion and watch for early signs of heat stress. These breeds don’t handle heat well because of their shorter airways.
