Heat Stroke in Dogs

Summer is a time for long walks, trips to the park, and backyard play—but when temperatures rise, so does the risk of heat stroke in dogs. Unlike humans, dogs can’t sweat to cool off. Instead, they rely on evaporative cooling which happens when air moves over the moist surfaces of their mouth during panting. With fur coats and lacking the ability to sweat, dogs are especially vulnerable to overheating, especially during hot days.

In this post, we'll cover what heat stroke is, how to recognize the signs, and how to keep your dog safe.

What Is Heat Stroke in Dogs?

Heat stroke occurs when a dog’s body temperature rises dangerously high (typically over 104°F or 40°C) and the body cannot cool itself effectively. If not treated immediately, heat stroke can lead to organ failure or even death.

Signs and Symptoms

• Excessive, uncontrollable panting

• Bright red gums

• Actively seeking shade, water or other spots to cool off

• Losing interest in activity such as hiking or chasing a ball

• Distress and anxiety

• Vomiting or diarrhea

• Lethargy or uncoordinated movement

• Collapse or seizures

If your dog exhibits any of these symptoms, begin cooling them off right away and identify the nearest open veterinary clinic.

Dogs at Higher Risk

While any dog can suffer from heat stroke, certain dogs are more vulnerable:

• Brachycephalic breeds (like Bulldogs, Pugs, Boxers) due to short snouts which make it more difficult to get adequate airflow

• Older dogs or those with heart or respiratory conditions

• Overweight dogs

• Dogs with long, thick or double coats

Prevention Tips

1. Never leave your dog in a parked car! Temperatures can rise to fatal levels within minutes. Dark or black colored cars can heat up twice as fast as white/light colored cars.

2. Avoid midday walks. Go out during early morning or late evening when it's cooler.

3. Provide plenty of fresh, cool water at all times.

4. Use shade or cooling mats when outdoors.

5. Avoid hot asphalt and pavement to prevent burns on their paws.

What to Do If You Suspect Heat Stroke

1. Move your dog to a cool, shaded area immediately.

2. Apply cool water to their body, especially on the belly, paws, and head.

3. Use ice/cold packs wrapped in cloth on their belly, neck and armpits.

4. Offer cool water to drink. You may need to offer this in small quantities given over 10-40 minutes to prevent them from chugging it then vomiting.

5. Use a fan to help with evaporative cooling.

6. Go to the vet right away if your pet vomits, has diarrhea, collapses or has a seizure. Also take your pet into the vet if they can’t seem to be cooled off or if they show symptoms later in the day, after being cooled off.

Heat stroke in dogs is a serious and fast-moving condition, but it’s also highly preventable. By staying alert to the risks and responding quickly to warning signs, you can keep your furry friend safe all summer long.

Remember: if you’re hot, your dog is probably hotter. When in doubt, take a break in the shade, grab some water, and save the high-energy play for cooler days.
