How Hot Is Too Hot for Dogs?


We all love soaking up the sun, and chances are your dog enjoys basking in it too. But as a loving dog parent, it's important to know: how hot is too hot for dogs? While dogs enjoy a warm day, high temperatures can be dangerous if you're not careful. From understanding the safe temperature for dogs to spotting dog overheating symptoms, this guide has you covered with all the dog summer safety tips you need to enjoy sunny days without putting your pup at risk.

Whether you're heading to the park, beach, or just chilling in the garden, understanding how to keep dogs cool in hot weather is essential. Heatstroke in dogs is more common than many people think, and even a short walk during the wrong time of day can be too much. That’s why knowing the best temperature for walking dogs can help keep tails wagging safely.

Dog Heat Tolerance by Breed


Not all dogs handle the heat in the same way. Dog heat tolerance by breed varies massively. For example:

  • Short-nosed (brachycephalic) breeds like Bulldogs, Pugs, and Boxers struggle more in hot weather.

  • Thick-coated breeds like Huskies and Newfoundlands also find it tough to regulate their temperature.

  • Small or toy breeds can sometimes tolerate heat better due to their size, but they’re still at risk.

No matter the breed, it’s crucial to understand the signs of heat exhaustion in dogs so you can take action quickly.

Dog Overheating Symptoms


Spotting dog overheating symptoms early can be life-saving. Look out for:

  • Excessive panting or difficulty breathing

  • Bright red or pale gums

  • Vomiting or diarrhoea

  • Weakness or collapsing

If you notice these signs, move your dog to a shaded area, offer cool water, and contact your vet immediately. Quick action is critical to preventing long-term damage or even death from heatstroke in dogs .

Best Temperature for Walking Dogs


So, what’s the best temperature for walking dogs ? Generally, if it’s over 20°C (68°F), be cautious. Anything over 25°C (77°F) can be dangerous, especially for flat-faced breeds, seniors, or puppies. Try walking early in the morning or later in the evening when it's cooler. And always check the pavement with your hand – if it’s too hot for you, it’s too hot for your dog’s paws!

Brachycephalic Dogs in Hot Weather


Brachycephalic dogs in hot weather face unique risks. Their short noses make it harder to pant efficiently, which is a dog's primary way of cooling down. Keep these breeds indoors during peak heat, and make sure they always have access to fresh water and fans or air conditioning if possible.

These breeds are especially prone to heatstroke in dogs , so even short periods outside during the heat can be dangerous . Avoid unnecessary walks and stick to shaded areas.

Senior Dogs and Heat Safety


Older dogs may have existing health conditions that make regulating temperature more difficult. Senior dogs and heat safety require special attention:

  • Keep walks short and avoid midday heat

  • Provide a cooling mat or damp towel for them to lie on

  • Ensure they drink plenty of water

Senior dogs may also be slower to show dog overheating symptoms , so keep a close eye on their behaviour in hot weather.

Puppies in Summer Heat


Puppies are curious and full of energy, but they’re also more susceptible to extreme temperatures. When it comes to puppies in summer heat , be extra cautious:

  • Play in shaded areas only

  • Keep outdoor time brief

  • Provide plenty of cool, fresh water

Because they’re still developing, puppies can experience heatstroke in dogs more rapidly than adults. Keep your little one safe by prioritising rest and shade.

Dog Car Safety in Summer


One of the most critical rules of dog ownership: NEVER leave your dog in a car on a warm day. Even with windows cracked, the temperature inside a vehicle can soar dangerously high in minutes.

Here are some stats that might surprise you:

  • On a 22°C (72°F) day, the inside of a car can reach 47°C (117°F) within an hour

  • Dogs can die from heatstroke in dogs within 15 minutes

  • Leaving the air con running is not a safe option either – if it fails, the consequences could be deadly

If you see a dog left in a hot car, call emergency services immediately. Their life may depend on it.

Can Dogs Get Sunburn?


Yes, they can! While their fur provides some protection, certain breeds and areas (like the nose, ears, and belly) are vulnerable. Can dogs get sunburn? Absolutely – especially those with light-coloured or thin coats.

Use pet-safe sunscreen on exposed areas and avoid peak sun times. Prolonged exposure not only risks sunburn but can increase the chances of skin cancer in dogs. Ouch!

How to Keep Dogs Cool in Hot Weather


Looking for ways on how to keep dogs cool in hot weather ? Here are some easy, effective ideas :

  • Provide a shady spot or cooling mat for rest

  • Set up a paddling pool or sprinkler for play

  • Freeze treats or fill toys with frozen peanut butter or broth

Staying cool can be fun for your pup when you get creative!

Can Dogs Stay Outside in the Heat?


You might wonder: can dogs stay outside in the heat ? The short answer is: not for long. Even in shaded areas, outdoor temps can be risky during a heatwave.

If your dog must be outside:

  • Ensure constant access to shade and fresh, cool water

  • Use cooling gear like vests or mats

  • Limit activity and bring them indoors frequently

Dogs can't sweat like we do, and they overheat quickly. When in doubt, keep them in.
