Sunny days mean longer walks, fun adventures, and more time outside with your pup. But when the temperature rises, dogs are at risk of overheating, and unlike us, they can’t sweat to cool down. Instead, dogs regulate their body temperature mostly through panting, which doesn’t always keep them safe in hot weather.
Knowing when a dog is overheating and how to respond quickly can make all the difference. In this guide, we’ll cover the symptoms to watch for, what to do if it happens, and how to prevent it in the first place.
Why Dogs Overheat
Overheating can happen faster than you think. A few minutes of running on a hot day or even lounging in a poorly ventilated area may be enough to put your pup at risk. Certain dogs are especially vulnerable:
- Flat-faced breeds like pugs, bulldogs, and boxers
- Puppies and senior dogs whose bodies can’t regulate temperature as well
- Overweight dogs that may struggle more in the heat
- Dogs with health issues such as heart or respiratory conditions
- Dogs with dense double coats such as Siberian Huskies, Golden Retrievers, and German Shepherds
Even healthy, active pups can overheat if they play too hard during the hottest parts of the day.
Signs of Dog Overheating
The key to protecting your pup is catching the signs early. Watch for:
- Heavy, rapid, or noisy panting that doesn’t stop
- Excessive drooling or foamy saliva
- Bright red gums and tongue, or gums that look pale or gray
- Lethargy, weakness, or seeming “out of it”
- Vomiting or diarrhea
- Stumbling, collapse, or unresponsiveness
These symptoms may start mild but can progress quickly. If your dog shows more than one, treat it seriously and act right away.
What To Do if Your Dog Overheats
If you think your pup is overheating, don’t wait, it’s an emergency. Here’s what to do:
- Get to a cooler spot immediately: Move your dog into the shade, indoors with a fan, or an air-conditioned room.
- Offer small sips of cool (not ice-cold) water: Too much cold water at once can make things worse.
- Cool the body gradually: Wet a towel with cool water and place it on their paws, belly, or armpits, or lightly spray with room-temperature water.
- Call your vet right away: Overheating can lead to heatstroke, which is life-threatening without medical care.
According to the American Kennel Club, heatstroke in dogs requires immediate veterinary attention, even if your pup seems to recover.
How to Prevent Overheating in Dogs
The best way to protect your pup is prevention. Small adjustments to your summer routine can make a big difference:
- Avoid peak heat hours: Go for walks early in the morning or late in the evening.
- Keep fresh water available: Always bring a water bottle and collapsible bowl on outings.
- Provide shade and rest: Give your pup plenty of breaks in cool, shaded areas.
- Skip strenuous activity: On especially hot days, keep playtime indoors or low-key.
- Check the ground: Hot pavement can burn paws and contribute to overheating. Learn more in our guide on how to protect dog paws from hot pavement.
- Know your dog’s limits: Every dog handles heat differently, what’s safe for one may be too much for another.
