How to Keep Your Dog Cool in Summer (Without the Stress)

Dogs don't sweat the way we do. They pant, they seek shade, they press themselves against cool tiles — and if we're not paying attention, the heat can catch them off guard faster than we expect.

Summer with a dog is genuinely wonderful. Early morning walks, evenings in the garden, road trips with the windows down. But it comes with real responsibility, and the difference between a dog who thrives in the heat and one who struggles often comes down to a few consistent habits.

Here's what actually helps.

Know the Signs Before They Become a Problem

Most dogs won't tell you they're overheating until they really are. By the time you notice heavy panting, glazed eyes, or unusual lethargy, their body is already working hard to compensate.

The early signs are subtler: slower movement on walks, reluctance to play, seeking shade more than usual, or drinking more water than normal. These aren't dramatic, but they're worth noticing.

Flat-faced breeds like French Bulldogs, Pugs, and Bulldogs are particularly vulnerable because their airways are shorter, making it harder to cool down through panting. Older dogs, overweight dogs, and very young puppies also feel the heat more acutely. If your dog falls into any of these categories, summer requires a little extra thought.

Rethink Your Walk Schedule

This is the single most impactful change most dog owners can make, and it costs nothing.

Pavements absorb heat throughout the day and stay hot well into the evening. A surface that feels warm to your hand can be genuinely painful on a dog's paws — and if it's uncomfortable to hold your palm flat against the ground for five seconds, it's too hot for your dog to walk on.

Shift walks to early morning or after sunset. Not just slightly earlier — genuinely early, before 8am if possible during a heatwave. The difference in temperature between 7am and 11am on a hot day can be significant, and your dog will move more freely, sniff more enthusiastically, and enjoy the walk far more.

If your schedule doesn't allow for early walks, shorter and more frequent outings in shaded areas are better than one long walk in the midday heat.

Water: More Than Just a Bowl

Most dogs drink when they're thirsty, but thirst is already a sign of mild dehydration. Keeping water consistently available — and making it appealing — matters more in summer than any other time of year.

A few things that help:

Fresh water, changed regularly. Dogs are more likely to drink from a clean bowl than one that's been sitting in the sun all afternoon.

Multiple water points around the house. One bowl in the kitchen is fine in winter. In summer, having water in the garden, near their bed, and in any room they spend time in encourages more frequent drinking.

Ice cubes. Simple, but effective. Most dogs find them interesting to investigate and lick, which slows down drinking and keeps them hydrated over a longer period.

For walks, a portable water bottle designed for dogs makes a real difference. It removes the friction of finding water on the go and means you're never caught out on a longer route.

Create a Cool Space at Home

Dogs are good at finding the coolest spot in a room, but they can only work with what's available. A few small adjustments make a meaningful difference.

Keep curtains or blinds closed on south-facing windows during the hottest part of the day. It sounds minor, but rooms stay noticeably cooler when direct sunlight is blocked.

Cooling mats are worth considering for dogs who spend a lot of time indoors. They work through pressure-activated gel that absorbs body heat, and most dogs take to them quickly once they realise how good they feel.

Tiled floors are naturally cooler than carpet, so if your dog gravitates toward the bathroom or kitchen in summer, let them. They're self-regulating.

A fan positioned to circulate air rather than blow directly at your dog helps keep the room temperature manageable without causing discomfort.

Grooming Matters More Than You Think

A well-groomed coat actually insulates dogs from heat as well as cold — but only when it's clean, brushed, and free of matting. A tangled, dirty coat traps heat and makes it harder for air to circulate close to the skin.

Regular brushing during summer removes dead undercoat, which is one of the main culprits for overheating in double-coated breeds. A good grooming brush used a few times a week makes a noticeable difference, particularly for dogs who shed heavily.

Resist the urge to shave double-coated breeds like Huskies, Golden Retrievers, or German Shepherds. Their coat structure is designed to regulate temperature in both directions, and shaving can actually disrupt that process and increase sun sensitivity.

For short-coated breeds, a light wipe-down with a cool damp cloth after walks helps bring body temperature down quickly and removes any salt or grime from hot pavements.

Paw Care on Hot Days

Paws take a lot of punishment in summer. Hot pavements, dry ground, and rough surfaces can cause cracking, soreness, and in more serious cases, burns.

Checking your dog's paws after walks takes thirty seconds and tells you a lot. Redness, tenderness, or any reluctance to put weight on a paw are signs that the surface was too hot or too rough.

Dog boots are a practical solution for dogs who walk regularly on urban surfaces in summer. They look a little unusual at first, and most dogs need a short adjustment period, but they provide genuine protection on hot pavements and rough terrain. Our Waterproof Anti-Slip Dog Boots work particularly well because they handle both the heat and any unexpected wet surfaces.

Paw balm applied before and after walks helps maintain the integrity of the pad and prevents cracking from dry heat.

Never Leave a Dog in a Parked Car

This needs saying plainly: a car parked in direct sunlight on a warm day reaches dangerous temperatures within minutes, even with windows cracked. It doesn't need to be a heatwave. A mild, sunny day is enough.

If you're running errands, leave your dog at home. If you're travelling, plan stops where your dog can come with you or where someone can stay with them in the car with the engine and air conditioning running.

Travel and Outings in Summer

Summer often means more time out and about, and dogs generally love being included. A few adjustments make outings safer and more comfortable.

Carry water on every outing, regardless of how short it seems. Heat and excitement together increase dehydration faster than either alone.

If you're using a carrier or backpack for smaller dogs, make sure it has proper ventilation. Our Breathable Pet Carrier Backpack has mesh panels on multiple sides that allow air to move freely, which makes a significant difference on warm days.

Plan routes with shade. Parks with tree cover, coastal paths, and woodland trails are far more comfortable for dogs in summer than open urban routes with no shelter.

A Note on Heatstroke

Heatstroke in dogs is a genuine emergency. If your dog is panting extremely heavily, drooling excessively, vomiting, stumbling, or becomes unresponsive, move them to a cool area immediately, apply cool (not cold) water to their body, and contact a vet without delay.

Do not use ice-cold water or ice packs directly on the skin, as this can cause blood vessels to constrict and slow the cooling process. Cool, damp towels applied to the neck, armpits, and groin area are more effective.

Prevention is always better, but knowing what to do if it happens is equally important.

The Bigger Picture

Keeping a dog comfortable in summer isn't complicated, but it does require consistency. The habits that matter most — earlier walks, constant water access, a cool resting space, regular grooming — are all simple in isolation. Together, they make a real difference to how your dog experiences the warmer months.

Dogs are adaptable, and most of them genuinely enjoy summer when the conditions are right. A little preparation on your part means they can enjoy it safely.

Frequently Asked Questions

How do I know if my dog is too hot?

Watch for heavy, rapid panting, excessive drooling, lethargy, or reluctance to move. More serious signs include vomiting, stumbling, or glazed eyes. If you notice any of these, move your dog to a cool area and offer water. Contact your vet if symptoms don't improve quickly.

Can I walk my dog in summer?

Yes, but timing matters. Early morning and late evening are the safest times. Avoid walking on hot pavements during midday or early afternoon. The seven-second rule is a useful guide: if you can't hold your palm flat on the pavement for seven seconds, it's too hot for your dog's paws.

Do dogs need sunscreen?

Some dogs, particularly those with light-coloured or thin coats, can be susceptible to sunburn on exposed areas like the nose, ears, and belly. Pet-safe sunscreen is available and worth considering for dogs who spend extended time in direct sunlight. Never use human sunscreen on dogs, as some ingredients are toxic to them.

How much water should a dog drink in summer?

There's no single answer, as it varies by size, activity level, and temperature. A general guide is around 30–50ml per kilogram of body weight per day, but this increases significantly with heat and exercise. The most reliable indicator is consistent access to fresh water and monitoring whether your dog is drinking regularly.

Are cooling mats safe for dogs?

Most cooling mats designed specifically for pets are safe and non-toxic. Look for mats that activate through pressure rather than requiring refrigeration, as these are more practical for everyday use. Introduce the mat gradually if your dog is hesitant — most come around once they feel the difference.

What breeds struggle most in the heat?

Flat-faced (brachycephalic) breeds like French Bulldogs, Pugs, Bulldogs, and Shih Tzus are most vulnerable due to their restricted airways. Older dogs, overweight dogs, and very young puppies also need extra care. That said, any dog can overheat in extreme conditions, regardless of breed.
