Heatstroke in Dogs: What Every Owner Should Know

Your Essential Guide to Keeping Dogs Safe in the Summer Heat

As summer arrives in full swing, so does the risk of heatstroke—a potentially life-threatening condition for dogs. While we may enjoy the warmer weather, our canine companions are far more sensitive to heat than we are. Knowing how to spot the signs of heatstroke and how to prevent it can make all the difference.

🔥 What Is Heatstroke in Dogs?

Heatstroke (also known as heat exhaustion or hyperthermia) occurs when a dog’s body temperature rises to dangerous levels—typically above 40°C (104°F)—and they are unable to cool themselves down. Unlike humans, dogs can’t sweat through their skin. They primarily cool down by panting and through the pads of their feet, which makes them more vulnerable in hot, humid, or poorly ventilated environments.

If not treated immediately, heatstroke can lead to organ failure, brain damage, and even death.

🚨 Warning Signs of Heatstroke

Recognising the signs early is crucial. Be alert for the following symptoms:

• Excessive panting or drooling

• Lethargy or weakness

• Vomiting or diarrhoea

• Bright red or pale gums

• Incoordination or collapse

• Glazed eyes or signs of confusion

• Seizures in severe cases

If your dog displays any of these symptoms during warm weather, act quickly and seek veterinary attention immediately.

🧊 First Aid for Suspected Heatstroke

While you contact your vet or prepare for transport, here’s what you can do:

• Move your dog to a shaded, cool area.

• Offer small sips of cool (not cold) water.

• Use cool, damp towels on their paws, neck, and belly.

• Use a fan if available to increase airflow.

• Avoid ice or freezing water, as it can cause shock.

These steps do not replace veterinary care—your dog will still need to be assessed by a professional.

🌞 Top Prevention Tips: How to Keep Your Dog Cool

🕗 1. Avoid Peak Heat

Walk your dog during the early morning or late evening when temperatures are cooler. Midday heat is the most dangerous, especially on humid days or when the sun is strong.

💦 2. Provide Shade and Fresh Water

Whether at home or on the go, ensure your dog always has access to cool, shaded areas and clean drinking water. Consider using a cooling mat or vest for extra support on hot days.

🚗 3. Never Leave Your Dog in a Car

Even on a mild day, car interiors can reach deadly temperatures within minutes. Leaving a window cracked is not enough. A dog left in a hot car can die within 15 minutes.

🦮 4. Adjust Exercise

Skip intense games like fetch or running during warm spells. Choose enrichment activities like sniffing games or gentle walks in shaded areas to avoid overheating.

🧼 5. Be Aware of Breed

Some breeds—especially flat-faced breeds (e.g. French Bulldogs, Pugs), older dogs, puppies, and overweight dogs—are at higher risk. Dogs with thick coats may benefit from professional grooming to help reduce heat retention.

🧠 Know Your Dog’s Limits

Every dog is different. Some may tolerate warm weather better than others, but no dog is immune to the effects of extreme heat. Trust your instincts—if the ground is too hot for your hand, it’s too hot for their paws. If you're feeling the heat, your dog is feeling it more.

❤️ Final Thoughts: Summer Fun, Done Safely

Summer should be a time of adventure, connection, and fun with your dog—but it must be approached with care. Understanding how heat affects dogs and taking steps to avoid heatstroke ensures your dog stays happy, healthy, and safe.

Stay cool, stay aware, and never underestimate the power of a shady spot and a bowl of fresh water.
