6 hot tips for how to keep dogs cool in summer

Did you know that dogs don’t sweat through their skin like humans? Instead, dogs cool down by panting and releasing heat through their paw pads and nose—which is trickier for some breeds than others. And that's why, as a pet parent or pet sitter, it's vital you know how to keep dogs cool in summer.

Unfortunately, our dog's go-to cool down tricks aren't the most effective methods of regulating body temperature—so it’s up to us humans to know how to keep dogs cool in hot weather. Without further ado, bring on the tips!

How to keep dogs cool in summer

• Never leave dogs in cars
• Make your dog walks cool
• Pack plenty of water
• Try different ways to keep them hydrated
• Let them paddle or take a dip somewhere
• Keep grooming

1. Never leave dogs in cars

Rule 101 of keeping dogs cool: never leave a dog in a car — not even for a few minutes. An open window or a shaded parking spot isn’t enough to keep a car cool and, according to the RSPCA, the temperature of a car can quickly double that of outside. Knowing that a dog struggles to regulate their temperature even when outdoors, it’s not worth the risk. Dogs can quickly overheat in a matter of minutes and develop heat stroke, a life-threatening condition.

Similarly, be mindful not to leave your dog in a glass sunroom or an RV. These can become greenhouses in the sunshine and it’s just as dangerous as leaving them in the car.

2. Make your dog walks cool

When looking for how to keep dogs cool in hot weather, you don't need to research the trendiest treks to take your dog on (but if you do, here’s a helpful list of the top 100 pet-friendly places). We mean timing your dog walk for when it’s cooler, so early in the morning or late in the evening. It’s also a good idea to plan a shorter walk than usual, preferably one with plenty of shaded spots. 

Don’t forget that your dog’s paw pads can burn on hot pavement, concrete or a sandy beach, so we’d recommend walking them on the grass if possible. Our top tip is to place your hand on the surface you want to walk your dog for five seconds. If you can't keep your hand on the surface because it's too hot, it's also too hot for your dog to walk on the surface too!

Just like protecting your own skin, we recommend applying pet-safe sunscreen on the nose, ears, and other exposed areas of your dog. Apply the sunscreen at least half an hour before leaving the home for maximum effect.

3. Pack plenty of water

It's one of the bread-and-butter ways for how to keep dogs cool in summer, and every pet parent should know to make sure their pup's drinking enough water, especially when the sun’s out.

Walking in the heat is thirsty work and so water stops will be needed to keep your dog cool. Alongside your keys and poop bags, pick up a bottle of water if the sun’s out.

And if your dog won’t drink straight from the bottle, then we’d recommend investing in one of the many handy portable dog water bottles on the market — you can find them online and in almost all pet shops. 

Add ice cubes to your water bottle to help keep the water cooler for longer, and always keep an emergency backup water bottle in your car in case you lose or spill your regular water bottle.

4. Try these creative ways to keep them hydrated

Still worried your dog’s not drinking enough? Maybe you can’t keep track of their intake or their lower levels of exercise mean they’re just not as thirsty. Either way, knowing how to keep dogs cool in summer is almost synonymous with knowing how to get those liquid levels up.  

You could try making some tasty homemade dog ice cream or giving them a refreshing fruity snack that’s fun to make, like dog-safe pupsicles.

5. Remember water isn’t just for drinking

Wondering how to keep dogs cool outside? If possible, we recommend treating your dog to a paddling pool. It doesn’t have to be big or expensive, just somewhere your dog can jump in and out of for quick relief from the heat. 

We’d recommend putting the pool in the shade so that the water doesn’t heat up in the sun. It’s also a good idea to encourage dogs to dry off inside or in the shade so that they don’t heat back up quickly in the sunshine.

And if you're looking for something portable to keep your dog cool, check out these dog cooling mats. Dog cooling mats allow your dog to choose when they need some extra help cooling off. Keep your cool mats in the shade and place them on a flat surface.

6. Give your dog a good groom

It’s important that you give your dog a regular groom, as it assists in shedding that extra fur so they feel more comfortable in the sun. For dogs with particularly thick coats, it’s also important to have the coat professionally trimmed or thinned. 

If you're clipping your own dog’s coat, it may be tempting to shave them close to the skin to keep them cool — but it’s not recommended. Remember, a dog’s skin can burn like ours, and their fur actually plays an important role in protecting them from the sun. Using clippers at home also risks painful accidents like cuts to the skin.
