How to Keep Your Dog Cool in Summer — and Spot Signs of Heat Stroke
As temperatures rise, our canine companions face the same risks from heat that we do—sometimes even more so. As a dog trainer, I see far too many well-meaning owners underestimate how quickly dogs can overheat.
Here’s how to keep your dog safe, cool, and happy during the hot months—plus how to recognize and respond to the early signs of heat stroke.
Smart Ways to Keep Your Dog Cool
Walk early or late
Avoid midday walks when the sun is at its peak. Aim for early mornings or evenings when the pavement is cooler, and the air is gentler on your dog's body.
Watch the pavement
Always do the 7-second test: place your hand on the pavement. If it’s too hot for your hand, it’s too hot for your dog’s paws. Opt for grassy areas or shaded paths whenever possible.
Hydrate often
Bring water on every walk, hike, or outing. Offer frequent sips and make sure your dog’s bowl at home is always full of fresh, cool water.Bring water on every walk, hike, or outing. Offer frequent sips and make sure your dog’s bowl at home is always full of fresh, cool water.
Skip the shave
Surprisingly, shaving your dog’s coat can actually make them hotter. Their fur protects them from sunburn and helps regulate temperature. Instead, brush out the undercoat to improve air circulation.
Provide shade and air
Whether your dog is indoors or outside, make sure they have access to shade or a breezy area. Fans, open windows, a small pool of water to get into, or even a cooling mat can help bring down their body temperature.
Use cooling gear
There are great products like cooling vests, bandanas, and mats designed to keep dogs comfortable on hot days. Wetting a towel for your dog to lie on works too!
Never leave your dog in a car
Even with windows cracked, a parked car can turn into an oven in minutes. Heat stroke can begin quickly—even in the shade.
Know the Signs of Heat Stroke
Dogs don’t always show clear signs of distress until it’s serious.
Excessive panting or drooling
Bright red gums or tongue
Weakness or collapse
Rapid heart rate
Disorientation or glassy eyes
Vomiting or diarrhea
Seizures in extreme cases
If your dog shows any of these signs, act fast.
What to Do If You Suspect Heat Stroke
Move your dog to a cool, shaded area immediately.
Wet their body with cool (not cold) water, especially their belly, paws, and underarms.
Use a fan to help evaporate the water and lower their temperature.
Use a thermometer to monitor body temperature.
Offer them drinks of cool water.
Call your vet or emergency clinic as soon as possible—heat stroke can be deadly.
Final Trainer Tips
During training in the summer, keep the sessions short, shady, and offer water breaks.
Keep an eye on flat-faced breeds (like Bulldogs, Pugs, or Boxers)—they’re more vulnerable to overheating.
Obese dogs or seniors are also at higher risk.
With a few smart choices and vigilance, you can enjoy summer safely together. Remember, when in doubt, stay indoors and enjoy some training games in the A/C.
Stay cool and happy tails!
