How to Keep Your Dog Cool and Safe in a Heatwave


With the UK experiencing record-breaking temperatures this summer, keeping your dog safe in the heat has never been more important. This guide covers everything you need to know — from spotting the early signs of heatstroke to the best cooling products recommended by vets and dog welfare organisations.

Why Hot Weather Is Dangerous for Dogs

Unlike humans, dogs can only cool themselves by panting and through limited sweating via their paw pads. In extreme heat, this simply isn't enough. The RSPCA and the British Veterinary Association (BVA) both warn that heatstroke can develop rapidly — sometimes within minutes — and can be fatal if not treated immediately.

Flat-faced (brachycephalic) breeds such as Bulldogs, Pugs, and French Bulldogs are at highest risk, as are elderly dogs, overweight dogs, and those with underlying health conditions. But any dog can overheat in a UK heatwave.

Recognising the Signs of Heatstroke

Act quickly if you notice any of the following:

  • Heavy, excessive panting
  • Drooling more than usual
  • Bright red or pale gums
  • Lethargy, weakness, or stumbling
  • Vomiting or diarrhoea
  • Glazed eyes or confusion
  • Collapse or loss of consciousness

If you suspect heatstroke, move your dog to a cool, shaded area immediately, apply cool (not cold) water to their body, and call your vet without delay. Do not use ice-cold water, as this can cause shock.

Walk Timing: The Golden Rule

The BVA advises the simple five-second pavement test: press the back of your hand to the pavement for five seconds. If it's too hot for your hand, it's too hot for your dog's paws.

During a heatwave, restructure your walks around the coolest parts of the day:

  • Early morning — before 8am is ideal
  • Evening — after 7pm once the ground has cooled
  • Avoid midday entirely — 11am–3pm is peak heat

Keep walks shorter than usual, stick to shaded routes, and always carry water. Grass and woodland paths are far kinder on paws than tarmac or concrete.

Hydration: Keep Water Flowing

Dogs need constant access to fresh, cool water in hot weather. Practical tips:

  • Refresh water bowls frequently throughout the day
  • Place multiple bowls around the house and garden
  • Carry a portable water bottle and collapsible bowl on every walk
  • Add ice cubes to water bowls to keep them cool longer
  • Offer dog-safe frozen treats (plain frozen broth or frozen carrot sticks work well)

Creating a Cool Environment at Home

Your home can quickly become a heat trap. Help your dog stay comfortable:

  • Keep curtains and blinds closed during the hottest part of the day
  • Ensure good airflow — open windows on opposite sides of the house to create a through-breeze
  • Provide a cool, tiled floor area for your dog to lie on
  • Never leave your dog in a parked car, conservatory, or caravan — temperatures can reach lethal levels within minutes
  • Use a paddling pool in the garden for dogs that enjoy water

Cooling Products That Actually Work

The right gear makes a significant difference during a heatwave. Here are four products we stock that are trusted by dog owners and recommended by welfare professionals:

George Barclay ClimaCOOL Self Cooling Dog Mat

A pressure-activated cooling mat that requires no water, refrigeration, or electricity — it simply activates when your dog lies on it and recharges itself when not in use. Ideal for use indoors, in the car, or in the garden. Shop the George Barclay ClimaCOOL Self Cooling Dog Mat.

George Barclay ClimaCOOL Dog Cooling Jacket

Soak, wring, and wear — this evaporative cooling jacket keeps your dog's core temperature down during walks and outdoor activities. Lightweight and reflective, it's designed for active dogs in warm conditions. Shop the George Barclay ClimaCOOL Dog Cooling Jacket.

Ruffwear Swamp Cooler Zip™ Cooling Dog Vest

A premium evaporative cooling vest from one of the world's leading outdoor dog gear brands. The Swamp Cooler uses a three-layer design to maximise cooling efficiency — wet the outer layer, and evaporation draws heat away from your dog's body. Reflective trim adds visibility on early morning or evening walks. Explore the Ruffwear Swamp Cooler Zip™.

Engineered for working and active dogs, the Non-stop dogwear Cooling Vest uses evaporative cooling technology to regulate body temperature during exercise and warm-weather adventures. Lightweight, close-fitting, and easy to wet and wring out before use. Shop the Non-stop dogwear Cooling Vest.

Garden Safety

The garden can be just as hazardous as the street in a heatwave:

  • Always provide a shaded area — a garden parasol or shade sail works well
  • Never leave your dog outside unsupervised in high temperatures
  • Check that garden water features are accessible and safe
  • Keep grass trimmed to reduce grass seed risk in summer

Grooming in Hot Weather

It's a common misconception that shaving a double-coated dog will keep them cooler. In fact, a dog's coat acts as insulation against both cold and heat. Instead:

  • Brush regularly to remove dead undercoat and improve airflow
  • Consult a professional groomer before making any significant coat changes
  • Keep paw pads moisturised — cracked pads are more vulnerable to hot surfaces
