Hot weather can be dangerous for dogs. In many cases, heatstroke starts as something very ordinary: a walk, a short car journey, a game in the garden, or a “they seemed fine” moment.
The tricky part is that dogs do not always show early warning signs clearly, and many will keep running, playing, chasing, or retrieving long after their body should have stopped.
Knowing how to keep dogs cool in hot weather is not just about comfort. It is about prevention.
This complete hot-weather safety guide covers heatstroke risk, safe walking temperatures, breed vulnerabilities, hydration, home cooling, cooling enrichment, useful products, and hot-weather car travel.
Quick Answer: To keep dogs cool in hot weather, avoid exercising during the hottest parts of the day, provide constant access to fresh water and shade, use cooling mats or damp towels, swap high-energy games for calm enrichment, avoid hot pavements, and never leave dogs in cars.
Why Dogs Overheat Faster Than Humans
Unlike us, dogs cannot sweat efficiently through their skin. They mainly regulate temperature by panting and releasing small amounts of heat through their paw pads.
Panting works by evaporating moisture from the tongue and airways. When the air is hot or humid, this cooling system becomes less effective, which is why weather that feels “warm but manageable” to us can become dangerous for dogs.
Body fat also acts as insulation, meaning overweight dogs retain more heat. If you are unsure about your dog’s body condition, see Is Your Dog the Optimum Weight?.
Many hot-weather emergencies happen during everyday routines rather than extreme situations. A normal walk, a quick game of fetch, or a journey in a warm car can become risky much faster than people expect.
How Hot Is Too Hot to Walk a Dog?
Owners often search: “Is it too hot to walk my dog?” There is no single perfect number because risk depends on humidity, shade, wind, breed, coat type, fitness, weight, age, health, and how intense the activity is.
As a practical guide:
- Warm weather: use caution, especially with puppies, older dogs, flat-faced breeds, overweight dogs, and high-drive dogs.
- Hot weather: avoid strenuous exercise and stick to shade, calm enrichment, and short toilet breaks where needed.
- High humidity: increases risk because panting becomes less effective.
- Hot pavements: can burn paws even when the air temperature does not seem extreme.
Always perform the pavement test: place the back of your hand flat on the ground for five seconds. If it is uncomfortable for you, it is unsafe for paws.
Cloud cover does not remove risk. Hard surfaces can hold heat long after air temperatures peak, and artificial grass, patios, roads, and pavements can become much hotter than the surrounding air.
Dogs Often Do Not Stop Themselves
This is one of the biggest hot-weather risks. Many dogs will not simply stop when they are getting too hot.
High-drive breeds such as Labradors, Spaniels, Collies and many working-line dogs may continue chasing, retrieving, training, or playing even when overheating has already started. Their motivation can override sensible self-preservation.
Ball throwing, high-arousal recall games, fast running, and intense play can quickly become risky in hot weather. If your dog loves to work, retrieve, chase, or keep going, it is your job to be the sensible one. Slightly rude, I know, but someone has to be the adult.
Hot weather can also make dogs more irritable, more tired, and less tolerant. If your dog seems unusually snappy, restless, reactive, or unable to settle, heat may be one part of the picture. You may also find Trigger Stacking in Dogs and Ladder of Aggression in Dogs useful companion reads.
In hot weather, replace intensity with calm enrichment. A frozen LickiMat, Toppl, frozen feeder, or simple scatter feeding can help your dog settle without adding more heat and arousal. For more ideas, see 3 Frozen Toppl Ideas Dogs Love and How to Calm a Hyper Dog.
Dogs Most at Risk in Hot Weather
Any dog can overheat, but some dogs need extra support in hot weather.
- Flat-faced breeds, such as French Bulldogs, Pugs, Bulldogs and Shih Tzus
- Double-coated breeds, such as Huskies, Golden Retrievers and German Shepherds
- Working and high-drive dogs, especially those who keep going through discomfort
- Puppies and senior dogs
- Overweight dogs
- Dogs with heart, breathing, mobility, or underlying health conditions
- Dark-coated dogs who may absorb more heat in direct sun
None of this is about judgement. It is about recognising who needs extra support so we can prevent problems before they start.
Breed traits matter too. If you are unsure what your dog’s breed or type may be more vulnerable to, our Breed Guides can help you understand typical needs, risks, and behaviour patterns.
Signs of Heatstroke in Dogs
Heatstroke is a medical emergency. Early recognition matters.
- Excessive, frantic, or noisy panting
- Drooling or thick saliva
- Bright red, pale, purple, or tacky gums
- Vomiting or diarrhoea
- Weakness, wobbling, or disorientation
- Restlessness or distress
- Collapse
- Seizures
If you suspect heatstroke, start cooling your dog immediately and contact your vet straight away. Do not wait to see if they “settle”.
Current welfare advice is often summarised as cool first, transport second. Start cooling immediately, then seek veterinary advice as soon as possible. The RSPCA heatstroke guide explains this in more detail.
For more detail, our full guide on Heatstroke in Dogs: Signs, Symptoms & What To Do explains warning signs and when to seek urgent veterinary help.
How to Cool a Dog Down Quickly
Quick Answer: If your dog is too hot, stop activity immediately, move them into shade or a cool indoor space, offer small amounts of drinking water, cool them with water, increase airflow, and contact your vet if there are any signs of heatstroke.
If your dog is overheating, act calmly but quickly:
- Stop exercise, play, training, or stimulation immediately.
- Move your dog into shade, a cool indoor room, or an air-conditioned space.
- Offer small amounts of cool drinking water.
- Apply cool water to the body, especially the underside, paws, belly, and groin area.
- Use a fan or airflow to help heat leave the body.
- Contact your vet urgently if symptoms are significant or do not improve quickly.
A damp microfibre towel can be useful for cooling paws, the belly, and the underside during travel or after a short toilet break. Use it as a short cooling aid rather than wrapping your dog up for long periods, as trapped heat is the last thing we want.
Do not delay cooling while trying to find the “perfect” water temperature. If your dog is showing signs of heatstroke, cooling and veterinary advice are urgent.
Hydration and Hot-Weather Support
Hydration is one of the simplest ways to reduce hot-weather risk. Provide fresh water at all times, and bring water on walks, days out, and car journeys.
For everyday travel, the Road Refresher Non-Drip Bowl helps prevent spills while still giving your dog access to water.
If you are out and about, a Travel Water Bottle is one of the simplest hot-weather essentials to keep in your bag or car.
For longer journeys, warm days, or mild dehydration support, Oralade can provide electrolyte support designed specifically for dogs.
Frozen moisture-rich enrichment can also support fluid intake safely. Try Frozen Dog Treats for Hot Weather: Bone Broth Ice Cubes made with Bone Broth for Dogs, a frozen LickiMat, a stuffed Toppl, or the Frozen Enrichment for Dogs: LickiMat Yoggie Pot.
One more practical point: shared public water bowls can spread germs. See Why I Avoid Sharing Dog Water Bowls.

Keeping Your Home Cool for Dogs
Dogs can overheat indoors too, especially in poorly ventilated rooms, conservatories, cars, crates in direct sunlight, or upstairs spaces that trap heat.
Small changes at home make a big difference:
- Provide shaded resting areas indoors and outdoors.
- Allow access to tiled floors or cooler rooms.
- Use fans safely, making sure your dog can move away if they choose.
- Close curtains or blinds in rooms that heat up quickly.
- Offer multiple water stations.
- Use a Cooling Mat to help your dog rest comfortably.
- Use damp towels for short cooling sessions.
- Keep grooming consistent to remove loose undercoat and improve airflow through the coat.
A cooling mat can also become a calm “settle spot”. If your dog is unsure, scatter a few treats on it while they lie down so it becomes a positive place to relax.
Night-Time Hot Weather Tips for Dogs
Hot nights can be difficult for dogs, especially if the house has held heat throughout the day. Some dogs become restless, pant more, move around frequently, or struggle to settle.
Where possible, give your dog the choice to sleep in the coolest safe room. This might mean access to tiled flooring, a downstairs space, a safely placed fan, or a Cooling Mat. Keep fresh water nearby and avoid shutting dogs into warm rooms or crates where they cannot move to a cooler spot.
A small frozen LickiMat or calm chew before bed can help some dogs settle without adding more activity and heat.
Hot-Weather Enrichment Ideas
Hot weather is not the time for high-energy training drills or frantic fetch sessions. Dogs still need things to do, but the aim is to lower arousal rather than increase it.
Try:
- Frozen LickiMats
- Stuffed and frozen Toppls
- Frozen Kong Classics
- Frozen Dog Treats for Hot Weather: Bone Broth Ice Cubes made with Bone Broth for Dogs
- Scatter feeding in the shade
- Gentle sniffing games indoors
- Calm chewing with suitable natural chews
- Short dog paddling pool sessions under supervision
If your dog finds it hard to switch off, enrichment should be simple and calming. The goal is not to keep them busy for the sake of it. The goal is to help them rest, regulate, and stay safe.
Helpful enrichment products: LickiMat, Toppl, Kong Classic, Bone Broth for Dogs, Dog Paddling Pool, and natural chews.
Dogs in Hot Cars and Hot-Weather Travel Safety
Car temperatures can rise quickly, even if it does not feel scorching outside. Dogs should never be left unattended in a parked car, even with windows open.
For secure travel set-ups, car sickness tips and general travel essentials, see our Dog Car Travel Safety Guide.
Hot-weather car travel checklist:
- Never leave your dog unattended in a parked car. Not “just two minutes”. Not “windows cracked”.
- Cool the car before your dog gets in. Run air conditioning first, then load your dog once the cabin temperature drops.
- Check airflow reaches your dog. If your dog travels in the boot, make sure cool air reaches that area, not just the front seats.
- Avoid peak heat. Travel early morning or later evening where possible.
- Offer water little and often. A non-spill option like the Road Refresher Non-Drip Bowl helps.
- Carry water with you. A Travel Water Bottle is a simple hot-weather essential.
- Support hydration on longer travel days. Oralade can be useful if your dog is panting more than usual.
- Pack a cooling towel. A damp microfibre towel can help cool paws and the underside during breaks.
- Use chilled enrichment for calm. If transporting frozen enrichment, use an Insulated Lunch Box for LickiMats.
- Avoid heavy meals before travel. They can worsen nausea and add extra digestive load.
If your dog is panting hard, drooling heavily, seems unsteady, vomits, collapses, or is not recovering quickly after a stop, treat it as urgent. Start cooling and contact your vet.
Common Hot-Weather Mistakes
Most owners are trying to do the right thing. The problem is that hot-weather risk is easy to underestimate.
- Thinking “they’ll stop if they get too hot”
- Throwing balls or doing high-speed recall games in warm weather
- Walking on hot pavements, patios, roads, or artificial grass
- Leaving dogs in parked cars
- Assuming shade makes intense exercise safe
- Using heavy meals before travel or exercise
- Shaving double-coated dogs without professional advice
- Forgetting that indoor rooms can overheat too
Hot weather does not mean your dog needs to be bored. It just means we need to swap intensity for calm, cooling, low-arousal activities.

FAQ
How do I keep my dog cool in hot weather?
Keep your dog cool by avoiding exercise during the hottest parts of the day, providing shade and fresh water, using cooling mats or damp towels, choosing calm enrichment instead of intense play, avoiding hot pavements, and never leaving your dog in a parked car.
What temperature is too hot to walk a dog?
There is no single safe number for every dog because risk depends on humidity, shade, breed, weight, age, health, coat type, and exercise intensity. If the weather is hot or humid, stick to very short toilet breaks, avoid strenuous exercise, and check pavements before walking.
How do I cool a dog down quickly?
Stop activity immediately, move your dog into shade or a cool indoor space, offer small amounts of drinking water, cool their body with water, increase airflow, and contact your vet if there are signs of heatstroke such as collapse, vomiting, weakness, confusion, or frantic panting.
Are cooling mats safe for dogs?
Cooling mats are generally safe when used correctly. Choose non-toxic materials, supervise dogs who may chew them, and make sure your dog can move away if they choose. A cooling mat should be an option, not something the dog is forced to use.
Should I shave my dog in hot weather?
Usually no, especially for double-coated breeds. Regular grooming to remove loose undercoat is often safer than shaving because the coat can help protect the skin and support temperature regulation. Speak to a qualified groomer or vet if you are unsure.
Can dogs overheat indoors?
Yes. Dogs can overheat indoors, especially in conservatories, upstairs rooms, poorly ventilated spaces, crates in direct sun, or warm cars. Provide shade, airflow, fresh water, cool resting areas, and the choice to move to a cooler place.
What products help keep dogs cool in hot weather?
The most useful products are usually simple ones: a cooling mat, travel water bottle, non-drip water bowl, microfibre towel, bone broth for frozen enrichment, frozen enrichment toys, and a supervised paddling pool. Products help, but they should support good management rather than replace shade, rest, water, and avoiding intense exercise.
