Know When It’s Too Hot to Walk Your Dog
June 22, 2026
With the heatwave forecast to bring temperatures of 28 – 36°C this week in Surrey, we wanted to re-share some of our top advice articles on how to avoid heatstroke in pets. As always, we’re here if you need us in an emergency or for general advice and pet care – call 01372 460107.
We all know dogs love their walkies in Surrey but when the weather heats up, it’s important to pause and check the temperature before heading out. Even on warm days that feel fine to us, your dog could be at risk of heatstroke.
As a general guide, 24°C (75°F) and above is considered too hot for a safe walk for many dogs. In fact, heat-related problems can start to creep in even from 20°C (68°F), depending on your dog’s breed, age, and health. Here’s a quick breakdown to help you decide:
- Below 20°C (68°F): Usually safe, though you should still consider your dog’s individual needs – full sun at lower temperatures can still be problematic for some dogs.
- 20–23°C (68–74°F): Getting warmer – there’s a moderate risk of overheating, especially during energetic play.
- 24–27°C (75–81°F): High risk of heatstroke for lots of dogs. It’s safer to skip the walk or keep it very short and gentle.
- 28°C (82°F) and up: Danger zone! It’s best to stay indoors or stick to shady garden time.

Why do dogs struggle in the heat?
Claygate Vets’ team advise that unlike humans, dogs can’t cool down by sweating.
Dogs lose very little heat through their paw pads and depend mainly on panting to keep cool. Because of this, they can become dangerously hot far quicker than many owners realise – particularly when they’re exercising. The RSPCA reports that dogs are up to ten times more likely to develop heatstroke during a walk than when left in a hot car. Both situations are extremely risky and can escalate into life-threatening emergencies within minutes..
Common symptoms of heatstroke in dogs
Claygate Vets’ team share signs your dog may be overheating:
- Heavy panting
- Difficulty breathing
- Excessive drooling
- Lethargy or confusion
- Vomiting or even collapse
If your dog shows any of these symptoms, move them to a shaded, cool place right away. Our vets in Claygate advise pouring cool (not ice-cold) water over your dog’s body, avoiding the head, and seeking veterinary help immediately. Never lay a damp towel over your dog as this can trap the heat in.
Claygate Vets’ emergency number is 01372 460107.

Other factors that affect dogs in the heat
Breed and health matters: Some dogs feel the heat more than others. Brachycephalic (flat-faced) breeds like pugs and bulldogs, along with puppies, senior dogs and pets with medical conditions, are more prone to overheating.
What they’re doing: A slow wander might be manageable, but chasing a ball or walking briskly can raise your dog’s body temperature quickly on warm days in Surrey.
Surface temperature: Pavements can be scorching even if the air feels comfortable. Use the ‘hand test’ – if you can’t hold your hand on the ground for a few seconds, it’s too hot for your dog’s paws.
Weather extras: Don’t forget how much sun, humidity or breeze can affect how the temperature feels. Still, muggy days can be especially tough for dogs.
Social stop-ins: Out on a walk and bump into a friend? Time flies mid-chat – but take a moment to check if your dog needs a water break or a move into the shade.
Claygate Vets’ top tips for safe summer dog walks
- Early morning or late evening will be the coolest times to walk your dog.
- Pick shady routes and avoid long stretches in direct sun.
- Carry water for both you and your dog.
- Watch for signs of overheating like panting, drooling, slowing down or seeming confused.
- Keep walks short and sweet – or give them a miss altogether if it’s sweltering.
- Skip the walk entirely and enjoy a relaxed indoor play session or a shaded potter in the garden
- When in doubt, it’s always better to be cautious.
