How to Keep Your Dog Cool in a Heatwave

When the UK is gripped by a heatwave, it's not just us who feel the heat. Our four-legged friends can really struggle too. Dogs can easily overheat, especially breeds with thick coats or flat faces. In fact, the British Veterinary Association warns that brachycephalic breeds such as pugs and bulldogs are at much higher risk of heatstroke due to their restricted airways and inability to regulate temperature effectively.

Whether you're out on a summer adventure or relaxing at home, here are our top tips for keeping your dog cool during hot weather.

1. Walk Early or Late

Avoid walking your dog during the hottest part of the day. Early mornings and late evenings are much cooler and far safer for exercise. Always check the pavement with the back of your hand. If it’s too hot for you, it’s too hot for their paws. It goes without saying, but keep walks shorter and choose shade routes where possible

2. Provide Plenty of Fresh Water

Hydration is everything. Make sure your dog has constant access to clean, cool water both at home and when you’re out and about. Portable dog water bottles or collapsible bowls are a game changer for walks, car trips or days out.

3. Create Cool Resting Spots

Indoors, close blinds or curtains and keep fans running to create a breezy, shaded space. Outdoors, set up a parasol or create a shaded corner with access to a cool surface. Dogs love lying on cool tiles or even a damp towel.

4. Use a Dog Cooling Vest or Bandana

Cooling vests and bandanas are soaked in water and help regulate your dog’s body temperature through evaporation. They’re lightweight, reusable and especially handy if your dog is active during the day.

5. Never Leave Dogs in Cars

We don't think this is something we need to say... but it’s worth repeating: never leave your dog alone in a car, even with the windows slightly open. Temperatures inside can rise to dangerous levels within minutes, which can be fatal.

6. Make Treat Time Chilled

Frozen dog-friendly treats are a fun way to help keep them cool. Stuff a toy with wet food and freeze it, or make simple pupsicles with dog-safe ingredients like peanut butter, banana and water. 

7. Keep an Eye Out for Heatstroke

Dogs regulate heat less efficiently than humans, and their body temperature can rise quickly during a heatwave. A normal dog’s internal temperature should sit between 38°C and 39°C. If it climbs above 40°C, it becomes dangerous. At over 41°C, heatstroke is likely and can become life-threatening.

Signs of heatstroke include:

• Heavy or rapid panting
• Excessive drooling
  
• Vomiting or diarrhoea
• Lethargy, confusion or unsteady movement
• Collapse or seizures in severe cases

If you suspect heatstroke, act fast. Move your dog to a shaded or cooler spot, offer small amounts of water, and gently cool them with lukewarm (not ice-cold) water or damp towels. Contact your vet immediately. Fast intervention is critical.

Stay Cool, Stay Safe

Summer can still be packed with fun, even during a heatwave. It just takes a little extra care. By planning ahead and tuning into your dog’s needs, you’ll both enjoy the sunshine safely.
