What temperature is too hot to walk a dog in the UK?

Many vets advise avoiding walks in the hottest part of the day when temperatures exceed roughly 20°C for sensitive breeds, or when pavement is too hot to hold your hand on for five seconds. Flat-faced breeds need extra caution at lower temperatures.

How do I test if pavement is too hot?

Place the back of your hand on the tarmac for five seconds. If it is uncomfortable for you, it can burn paw pads. Walk on grass where possible, or exercise at dawn and dusk.

Can I walk my dog if they still want to go?

Dogs may not stop themselves overheating. Short toilet breaks on grass in shade are safer than full walks in midday heat. Prioritise cooling and hydration over exercise.

Exercise in hot weather dogs

Quick answer

In a UK heatwave, **walk dogs at dawn or dusk**, skip walks when pavement burns your hand, and never rely on midday exercise. Flat-faced breeds (Bulldogs, Pugs, French Bulldogs) overheat faster. Check the air temperature with our too-hot-to-walk checker. If your dog is panting heavily, lethargic or vomiting after heat — treat as heatstroke and call a vet immediately.

Key takeaways

Many UK vets cut exercise for sensitive dogs from around 20°C, and skip normal walks in the mid-20s — pavement can be far hotter than the air.
Do the five-second hand test on tarmac. If you would pull away, it can burn paw pads.
Heatstroke is an emergency: heavy panting, bright-red gums, vomiting or collapse need tepid cooling and a vet, not an ice bath.
