How to Prevent Dog Heat Stroke and Keep Them Safe This Summer

Myth #1: “If I’m comfortable, my dog is too.”

Reality: Dogs don’t regulate heat the same way humans do.

 While we can sweat to cool off, dogs rely mostly on panting and limited sweat through their paws. Even if you’re feeling fine in warm weather, your dog might already be struggling. Dogs overheat much faster, especially in humid environments where panting becomes less effective.

👉 What to do instead: Always assess your dog’s behavior, not your own comfort level. Heavy panting, slowing down, or lying on cool surfaces are red flags even if it feels mild outside.

Myth #2: “Dogs will stop playing or running when they’re too hot.”

Reality: Dogs often don’t know when to quit.

Many dogs, especially high-energy breeds, will push themselves to keep up with you or continue playing, even while overheating. Their drive can override their physical limits especially during fetch or running with other dogs.

👉 What to do instead: You’re responsible for setting limits. Keep play sessions short and offer breaks in the shade every 10–15 minutes. If you notice glassy eyes or excessive drooling, stop immediately and help them cool down.

Myth #3: “Heat stroke only happens in extreme temperatures.”

Reality: Dogs can suffer heat stroke in 70–80°F weather, especially in humid conditions or poorly ventilated spaces.

 Heat stroke isn’t about numbers on a thermometer alone. It’s about how your dog’s body handles internal heat buildup, which can happen surprisingly fast, especially in enclosed or shaded spaces with poor airflow.

👉 What to do instead: Don’t wait for 90-degree forecasts to change your routine. Be cautious anytime it’s warm, especially if your dog is brachycephalic (short-nosed), overweight, or has a thick coat.

Myth #4: “If there’s water and shade, they’ll be fine.”

Reality: While helpful, water and shade aren’t always enough, especially if your dog has already started to overheat.

 Heat stroke can develop even when water is present if the dog isn’t actively drinking or if they’re in a high-stress or high-activity state.

👉 What to do instead: Encourage frequent hydration (offer water every 20 minutes during activity), use cooling methods like damp towels or cooling vests, and keep your dog’s environment as low-stimulation as possible during peak heat hours.

Myth #5: “Cracking the windows is enough to leave a dog in the car.”

Reality: A cracked window barely changes the internal temperature of a parked car.

 The inside of a car can reach deadly temperatures in under 10 minutes even on a mild day. Shade doesn’t help much either once the heat builds up.

👉 What to do instead: Never leave your dog in a car unattended. Even “just a few minutes” can be fatal. Plan ahead to ensure you’re never in a position to make that choice.

Myth #6: “Panting is normal. It means they’re just hot.”

Reality: Panting is how dogs cool down but excessive or heavy panting, especially when paired with drooling, restlessness, or uncoordinated movement, is a warning sign.

 Waiting until your dog shows more obvious signs could mean it’s already too late.

👉 What to do instead: Learn to spot early signs of heat distress and take them seriously. If you see exaggerated panting, bright red gums, or unusual behavior, move your dog to a cooler place, offer water, and call your vet.
