6 Signs of Heatstroke in Dogs Every Pet Owner Must Know

A Summer Day Gone Wrong

It was a scorching summer afternoon when Lisa took her Labrador, Buddy, for a short walk. Within minutes, his breathing became rapid, his tongue hung out excessively, and he slowed down. When they got home, Buddy collapsed on the floor, panting heavily. Lisa panicked, not knowing what was wrong. She had no idea that Buddy was suffering from heatstroke—a condition that could take his life within minutes.

Heatstroke in dogs is a medical emergency. Dogs can’t cool down like humans, and once their body temperature rises too high, it can lead to organ failure, brain damage, and even death. Recognizing the warning signs early and taking immediate action can mean the difference between life and death.

6 Signs of Heatstroke in Dogs

Dogs don’t sweat like humans; they rely on panting to regulate their temperature. When exposed to excessive heat, their bodies can quickly reach dangerous temperatures. Here are the 6 crucial signs of heatstroke in dogs:

1. Heavy Panting

If your dog is panting excessively and struggling to catch their breath, it’s a clear sign of overheating. This is usually the first warning of heatstroke.

2. Excessive Drooling

Drooling is normal for some breeds, but if your dog is producing thicker, stickier saliva or drooling excessively, it could be a sign of dehydration due to heatstroke.

3. Drowsiness and Lack of Coordination

A dog suffering from heatstroke may appear weak, sluggish, or disoriented. If they stumble, seem confused, or struggle to walk, immediate action is needed.

4. Diarrhea

Heatstroke can affect a dog’s digestive system, leading to diarrhea. In severe cases, you may notice bloody diarrhea, which is a sign of internal distress.

5. Vomiting

An overheated dog may begin vomiting as their body struggles to cope with rising temperatures. If vomiting is accompanied by other symptoms, seek emergency care immediately.

6. Collapsing

If your dog collapses, becomes unresponsive, or struggles to stand, this is a life-threatening emergency. Their organs may be failing, and they need immediate veterinary attention.

What to Do If Your Dog Shows Signs of Heatstroke

Heatstroke is deadly, but acting fast can save your dog’s life. Here’s what you should do:

🔴 Contact a Vet Immediately – Call your vet or the nearest emergency clinic. Heatstroke can cause irreversible damage within minutes.

🟢 Move Your Dog to a Shaded or Cool Area – Get them out of the sun and into an air-conditioned or shaded spot.

🟠 Cool Them Down Gradually – Pour small amounts of tepid (not cold!) water over their body, especially on the belly, armpits, and paws. Never use ice-cold water, as it can shock their system.

🔵 Offer Small Sips of Water – Gently let your dog drink small amounts of lukewarm water, and avoid overwhelming them with too much at once. For a thoughtful and easy way to keep your furry friend hydrated, consider this portable water bottle — designed with love for dogs on the go.

⚠️ DO NOT: Use ice packs, force water into their mouth, or submerge them in ice-cold water. These can make the situation worse.

Why Heatstroke Is So Dangerous

A dog’s normal body temperature is 101-102.5°F (38-39°C). If their temperature rises above 105°F (40.5°C), organs begin to fail, and death can occur within minutes. Even if they seem to recover, the internal damage could be severe. This is why immediate action is crucial.

How to Prevent Heatstroke in Dogs

The best way to protect your dog is prevention. Follow these essential tips to keep your furry friend safe:

✅ Never Leave Your Dog in a Parked Car – Even with the windows down, a car can turn into an oven in minutes.

✅ Avoid Midday Walks – Walk your dog early in the morning or late in the evening when temperatures are lower.

✅ Check the Pavement – If the ground is too hot for your hand, it’s too hot for your dog’s paws.

✅ Provide Shade and Water – Always have fresh, cool water available and ensure they have a shaded area.

✅ Use Cooling Mats and Fans – Cooling products can help regulate your dog’s body temperature.

✅ Know Your Dog’s Risk Level – Flat-faced breeds like pugs, bulldogs, and boxers are at higher risk due to breathing difficulties.

Buddy’s Second Chance

Lisa didn’t hesitate. She moved Buddy to a cool spot, poured tepid water over him, and called the vet. She acted fast, and it saved his life. The vet later told her that Buddy had been minutes away from organ failure.

From that day on, Lisa changed how she cared for Buddy in the summer. No more midday walks, always fresh water, and lots of shade. She couldn’t imagine losing him. Could you imagine losing yours?
