7 Key Signs of Heatstroke in Dogs — and What to Do

We all love sunny days, but for our furry friends, heat can be a real threat. Dogs don’t sweat like us, and with their fur coats, they can overheat in no time. Heatstroke can sneak up quickly, so being vigilant is crucial.

When your dog starts showing signs of heatstroke, it’s time to act fast. By recognizing these signs early, you can prevent a dangerous situation from turning into an emergency. Here’s what to watch for when the temperature rises.

Excessive Panting

Panting is normal when dogs are hot, but excessive panting is a big red flag. If your dog is panting heavily and struggling to catch their breath, they’re likely overheating. Offer water and move them to a cool spot immediately.

Bright Red or Pale Gums

Healthy dog gums are pink, but if they’re bright red or pale, something’s wrong. Red gums indicate heat stress, while pale gums are a sign of poor circulation. Either way, it’s time to get your pup cooled down quickly.

Lethargy or Disorientation

If your dog seems unusually tired, weak, or confused, they might be suffering from heatstroke. Dogs usually get a little sluggish in the heat, but a drastic change in behavior is a major sign they need attention—now.

Excessive Drooling

Drooling is normal for some dogs, but when heatstroke hits, drool can become excessive. If your dog’s slobbering more than usual and can’t seem to stop, it’s time to get them indoors and cool them off with water or a fan.

Vomiting or Diarrhea

Heatstroke can wreak havoc on your dog’s digestive system, leading to vomiting or diarrhea. These symptoms, coupled with other signs of heat stress, mean your dog’s body is struggling to cope with the extreme heat. Hydration and cool-down time are essential.

Uncoordinated Movements

If your dog’s legs start to wobble, they’re unsteady, or they appear to be stumbling, it’s a serious sign of heatstroke. Their body is in distress, and it’s crucial to move them to a cool place and offer water to prevent further complications.

Seizures

Seizures are a sign of severe heatstroke and require immediate veterinary attention. If your dog starts shaking uncontrollably, twitching, or convulsing, it’s time to call the vet. This is an emergency situation—don’t wait to act.

Act Fast, Cool Them Down

If you notice any signs of heatstroke, get your dog to a cool area immediately. Offer them cool (not cold) water and use a damp towel to help bring their body temperature down. If symptoms persist, head to the vet right away.

Keep Cool and Be Prepared

Preventing heatstroke is much easier than treating it. Keep your dog in shaded areas, offer plenty of fresh water, and avoid walks during peak heat hours. With a little preparation, you and your dog can enjoy the sunny days safely and comfortably.
