How to Keep Your Dog Cool in Summer: 9 Vet-Approved Tips

Summer is supposed to be fun. Long evening walks, trips to the lake, lazy afternoons on the porch. But if you have a dog, summer also demands extra vigilance. Dogs regulate heat far less efficiently than people do, they cannot sweat through their skin the way humans can, and heatstroke can turn fatal in under fifteen minutes.

Heatstroke cases in veterinary clinics are overwhelmingly preventable, and the majority could have been avoided entirely. Here are nine strategies that actually work to keep your dog safe when the mercury rises.

1. Shift Your Walk Schedule

This is the single most impactful change you can make. During heat waves, walk your dog before 8 a.m. and after 7 p.m. The midday and early afternoon hours are when pavement temperatures peak, asphalt can reach 60°C (140°F) when the air temperature is only 30°C (86°F). That is hot enough to cause serious paw pad burns within seconds.

A simple test: place the back of your hand flat on the pavement and hold it for seven seconds. If it is too hot for your hand, it is too hot for your dog's paws.

2. Provide Constant Access to Fresh Water

This sounds obvious, but many owners underestimate how much more water their dog needs in summer. A 25-kilogram dog may need double their usual water intake on a hot day. Place multiple bowls around the house and garden. If you are heading out, bring a collapsible travel bowl and a bottle of water specifically for your dog.

Adding a few ice cubes to their bowl can make the water more appealing and keep it cooler for longer.

3. Create Cool Resting Spots

Not every dog has access to air conditioning, and that is fine. A few inexpensive adjustments can make a big difference:

• Cooling mats: Pressure-activated gel mats that stay several degrees below room temperature. No electricity needed.
• Damp towels: Lay a damp (not soaking) towel on the floor for your dog to lie on.
• Fans and tile floors: Dogs instinctively seek cool surfaces. Make sure they can access tiled areas, and position a fan to create airflow at their level.

4. Never Leave Your Dog in a Parked Car

Even with windows cracked. Even for five minutes. Even on a cloudy day. The interior of a parked car can reach lethal temperatures in under ten minutes. This is non-negotiable. If you cannot bring your dog inside the shop or restaurant, leave them at home.

5. Adjust Exercise Intensity

Your border collie may want to chase a ball for forty minutes straight, but in 32°C weather, that level of exertion can push their core temperature into dangerous territory. On hot days, replace vigorous fetch sessions with shorter games, puzzle toys, or gentle swimming. Mental enrichment tires dogs out without the heat risk.

6. Try Frozen Treats

Frozen enrichment is a summer lifesaver. Fill a Kong or similar toy with plain yogurt and banana, then freeze it overnight. You can also freeze low-sodium chicken broth in ice cube trays for quick snacks. These keep your dog occupied, hydrated, and cool at the same time.

7. Watch for Early Warning Signs

Heatstroke does not always announce itself dramatically. Learn the early signals so you can intervene before things escalate:

• Excessive panting that does not slow down after resting in shade
• Thick, ropy drool
• Red or purple gums
• Glazed eyes or a dazed expression
• Reluctance to move or sudden wobbliness
• Vomiting or diarrhea

If you spot any combination of these, act immediately. Cool water on the belly and inner thighs, airflow from a fan, and a call to your vet.

8. Protect Their Paws

Beyond timing your walks, you can protect paw pads with dog-specific booties or paw wax. If your dog refuses booties (and many will), stick to grassy paths and shaded sidewalks during warmer hours. After every walk, check the paw pads for redness, blistering, or roughness.

9. Consider a Summer Trim, But Do Not Shave

A light trim can help long-coated breeds stay cooler, but resist the urge to shave your dog down to the skin. A dog's coat actually provides insulation against both heat and cold, and it protects against sunburn. Shaving a double-coated breed like a Husky or Golden Retriever can damage the coat permanently and may make them hotter, not cooler.

A professional groomer can advise on an appropriate summer length for your dog's specific coat type.

When Summer Gets Dangerous

Most summer heat situations are manageable with a bit of planning. But certain dogs are at higher risk and need you to be especially attentive: puppies under six months, senior dogs, overweight dogs, and any breed with a flat face. If your dog falls into any of these categories, consider keeping them indoors during peak heat hours entirely.

Summer should be a season you and your dog enjoy together, just with a little extra preparation. Keep those water bowls full, stick to shaded paths, and trust your instincts if something seems off. Your dog is counting on you to be their thermostat.
