Walking Dogs in Hot Weather: How to Keep Your Dog Safe This Summer

As the temperatures rise and the Hampshire countryside bursts into summer bloom, it’s only natural to want to head outside with your dog. But walking dogs in hot weather can pose serious health risks, from burnt paws to deadly heatstroke. In this blog, we’ll look at everything you need to know to walk your dog safely when the weather warms up – including signs of overheating, safe times to walk, and practical tips to keep your dog cool and comfortable.

Why Hot Weather Is Dangerous for Dogs

Dogs are more vulnerable to heat than we are. Unlike humans, who cool down by sweating, dogs regulate their temperature primarily by panting. This isn’t always efficient, especially in humid conditions or when they’re exercising. Flat-faced (brachycephalic) breeds like Bulldogs and Pugs are particularly at risk, as are puppies, older dogs, and those with health conditions or thick coats.

The Main Risks:

• Heatstroke: A potentially fatal condition where the dog’s body temperature rises dangerously high.

• Burnt paw pads: Pavements, sand, and even artificial grass can become scorchingly hot.

• Dehydration: Even mild fluid loss can lead to fatigue and overheating.

• Overexertion: Dogs don’t always know their limits—especially energetic breeds who love a run.

When Is It Too Hot to Walk Your Dog?

The general rule of thumb is that anything over 20°C (68°F) could be risky depending on humidity, breed, and time of day. Once it hits 24°C+, it's best to avoid walks altogether unless you're out very early or late.

The Tarmac Test

Place the back of your hand on the pavement for 7 seconds. If it’s too hot for your hand, it’s too hot for your dog’s paws.

Early Mornings and Late Evenings: Your Best Bet

In the summer months, aim to walk your dog:

• Before 8am (ideally around sunrise)

• After 8pm, once the sun has dipped and the ground has cooled

Shady woodland paths, such as those in Waggoners Wells or Hogmoor Inclosure, are ideal as they stay cooler throughout the day. If you can find somewhere that has safe water en route for your dog to have a swim or a paddle, even better.

How to Tell If Your Dog Is Too Hot

Spotting the early signs of overheating is crucial. Symptoms of heat stress or heatstroke include:

• Excessive panting

• Drooling

• Lethargy or collapse

• Bright red gums or tongue

• Vomiting or diarrhoea

• Confusion or unresponsiveness

Immediate action is vital. Move your dog into the shade, cool them with tepid water (not ice-cold), offer small sips of water, and call your vet.

10 Tips for Safe Summer Dog Walks

1. Walk in Natural Shade

Stick to shady areas like forests, parks with tree cover, or shaded footpaths. Avoid exposed downland and fields during the heat of the day.

2. Carry Water – for You and Your Dog

A collapsible bowl and fresh water are must-haves. Offer water frequently and never assume your dog will drink enough by themselves.

3. Use a Cooling Vest or Bandana

Cooling gear can help regulate your dog’s temperature. Wet the bandana or vest with cool water before setting out.

4. Avoid Pavement and Sand

Grass and natural surfaces are best. Even if the air temperature feels bearable, pavements can reach up to 50–60°C in the sun.

5. Cut Down the Intensity

Walks should be shorter and slower in hot weather. Swap the 5k run for a gentle sniffari (sniff-based walk) to engage your dog’s brain without overheating their body.

6. Check the UV and Heat Index

Apps like Weather & Radar or the Met Office app will show you the real-feel temperature and sun intensity. Both affect how safe it is for your dog to be outdoors.

7. Use Doggy Sun Cream

Yes, it’s a thing! Dogs with pink noses, sparse fur, or white coats can get sunburnt. Choose a dog-safe sunscreen and apply to ears, nose, and belly if exposed.

8. Brush Out the Undercoat

For double-coated breeds, regular grooming removes trapped fur that can hold in heat. Never shave your dog unless recommended by a vet—it can interfere with natural temperature regulation.

9. Offer Enrichment Instead

If it’s too hot to walk, don’t feel guilty. Use frozen KONGs, lick mats, puzzle toys, or shaded garden freework to mentally tire your dog without physical exertion.

10. Know Your Dog’s Limits

Some dogs simply don’t cope well in heat. Observe how your dog responds to rising temperatures and adjust your plans accordingly.

Alternatives to Hot Weather Walks

When walking is out of the question, here are a few ways to keep your dog cool, stimulated, and happy:

• Paddling pools: Supervised splashing is a great low-impact activity.

• Indoor scent games: Hide treats around the house or under cups for your dog to find.

• Frozen enrichment: Stuffed frozen KONGs or trays with broth and treats can keep them occupied for ages.

• Training sessions: Practise trick training or short recall games indoors or in shaded areas.

What to Do If You Suspect Heatstroke

Heatstroke is an emergency. Even a delay of a few minutes can be fatal.

First Aid Steps:

1. Move your dog to a cool, shaded place immediately.

2. Offer small amounts of water – do not force them to drink.

3. Drape cool (not ice-cold) wet towels over their body.

4. Direct a fan on them if possible.

5. Call your vet and head to the clinic right away.

A Note on Leaving Dogs in Cars

Never leave a dog in a parked car, even for a few minutes. Temperatures can soar to fatal levels within 10 minutes, even with windows cracked open. It’s simply not worth the risk.

Final Thoughts

Hot weather doesn’t have to mean boredom for your dog—but it does mean rethinking your usual routine. Early or late walks, shady woodland paths, cooling gear, and enrichment at home can all help you strike the right balance. Above all, trust your instincts and prioritise your dog’s wellbeing over daily exercise quotas.

If in doubt, skip the walk and try a frozen lick mat or a cool garden activity instead. Your dog will thank you!
