The first proper heatwave hits and the house turns into an oven. Your dog’s flopped on the kitchen floor, panting away, and you’re stood there with a fan wondering if you’re doing enough. Sound familiar?
Keeping a dog cool in hot weather is one of those things we barely think about in Britain, right up until the week we really need to. Most of our homes have no air con. Our dogs are built for a good drizzle, not a Mediterranean summer. And the older ones feel it more. Poppy’s 11 now, and she slows right down the moment it warms up.
Here’s the good news. You don’t need to spend a fortune to sort this. A few cheap bits and a couple of small changes to your day make a real difference. Let’s go through what actually works.

First, How to Spot a Dog That’s Too Hot
Before any of the kit, learn the signs. Dogs cool themselves mostly by panting, not by sweating the way we do, so they overheat a lot quicker than people expect.
Keep an eye out for heavy, frantic panting, more drooling than usual, very red gums, a wobbly or unsteady walk, or a dog that just seems off and can’t settle. Flat-faced breeds, older dogs, puppies, and overweight dogs feel the heat worst of all. But any dog can overheat on a hot day, so it’s worth knowing what you’re looking for.
When to Ring the Vet
If your dog is staggering, being sick, collapsing, or seems confused, treat it as an emergency. Move them somewhere cool, offer small sips of water, wet their coat with cool water (not ice-cold, more on that in a second), and ring your vet straight away.
Heatstroke can turn serious fast, so don’t sit and wait to see if it passes. When in doubt, phone them. There’s more on when to get professional help in my vet tips for dogs post.
Keep the Water Cold and Always There
Warm water in a bowl is about as tempting to your dog as a lukewarm cuppa is to you. On hot days they need cold water, and plenty of it.

Drop a few ice cubes in the bowl, or freeze a small water bottle and stand it in the middle so it melts slowly through the day. Put out more than one bowl too. One inside, one in the shade outside, so there’s always a fresh drink going. If you’re heading out, an insulated travel bottle means you can offer a drink wherever you are.
Quick myth to clear up, since it worries a lot of owners: cold water and a few ice cubes are perfectly fine for a healthy dog. The old story about ice water being dangerous has been largely debunked. Just use common sense and don’t let a hot, thirsty dog gulp a huge amount all at once.
Give Them a Cool Spot to Lie On
Dogs will hunt out the coolest bit of floor they can find, usually the tiles, and usually right where you need to walk. A cooling mat gives them a proper spot to stretch out instead.

The gel-filled ones are the easy option. No electricity, no freezer, no faff. Your dog lies on it, the gel draws the heat away, and that’s it. The trick is picking one your dog will actually use. Pop it where they already like to sleep rather than somewhere brand new, and give them a day or two to trust it. Some dogs take to it straight away, others need a little coaxing.
Cooling Coats and Bandanas
Putting a coat on in the heat sounds backwards, I know. But a cooling coat works like a wet towel that stays damp for hours. You soak it, wring it out, pop it on, and as the water evaporates it pulls heat away from your dog.
They’re handy for walks, car journeys, or a warm room where your dog’s really feeling it. If a full coat feels like overkill, a soaked cooling bandana is the cheaper, lighter version and does a similar job around the neck.
Frozen Treats and Lick Mats
A frozen treat cools a dog from the inside and keeps them busy for a good half hour, which is a lovely bonus on a day they can’t have a proper walk. Smear a little dog-safe peanut butter or some wet food onto a lick mat and freeze it. Cheap, simple, and they adore it.

You can freeze plain natural yoghurt into cubes too, or make your own frozen treats with just a few ingredients. I’ve got a quick recipe over on my 3-ingredient dog treats post if you fancy it. Just double-check anything you use is safe for dogs, and keep the portions sensible.
Change Your Walk Times (and Mind the Pavement)
On a hot day, the midday walk is the one to skip. Early morning and later in the evening are cooler and much kinder, for their paws and for you.

Before you set off, do the seven-second test. Press the back of your hand flat to the pavement and hold it there for seven seconds. If it’s too hot for your hand, it’s too hot for their paws. A paw balm helps protect the pads on rougher, warmer ground.
And on the days when it’s just too hot for a walk at all, don’t feel guilty about it. There’s loads you can do to keep them happy and busy indoors instead, from puzzle games to a bit of gentle training. I’ve rounded up my favourites in my summer activities for dogs at home post.
Cool the House and Garden Without Air Con
You don’t need air con to take the edge off a warm house. Draw the curtains on the sunny side through the day to keep those rooms cooler. A fan helps, and a damp towel hung in front of it cools the moving air a touch more.
Out in the garden, the main thing is proper shade in the afternoon. A parasol or a bit of shade cloth does the job nicely. And a cheap paddling pool with a few inches of water is a real summer winner for dogs that like a splash. Do stay with them around water though, even a shallow pool, just to be safe.
The Golden Rule: Never Leave Them in a Hot Car
This one never changes. A car heats up frighteningly fast, even with the windows cracked, even parked in the shade, even “just for five minutes”. It simply isn’t worth the risk. If your dog can’t come in with you when you arrive, leave them at home where it’s cool.
A Cool, Happy Dog All Summer
None of this is complicated or dear. Cold water, a cooling mat, a frozen lick mat, cooler walk times, and a bit of shade will see most dogs through a British summer perfectly comfortably. Just keep a closer eye on the older ones and the flat-faced ones, since they feel it most.
