When a UK heatwave hits, our dogs feel it just as much as we do, and unlike us they cannot strip off a layer or reach for a cold drink whenever they like. Older dogs, flat-faced breeds and thick-coated dogs in particular can really struggle once the temperature climbs, and a hot, restless dog is a miserable dog. A good cooling mat gives them a simple, low-effort spot to lie down and take the edge off the heat, whether that is in the lounge, the kitchen, the car or the garden.
In this guide we round up the best dog cooling mats you can buy in the UK in 2026, from self-cooling gel pads that need no water or electricity to evaporative mats for serious summer heat. We cover budget, mid-range and premium options, explain how the different types work, and help you choose the right size for your dog so everyone can ride out the warm weather in comfort.

Individual Product Reviews
The Green Pet Shop Cool Pet Pad
Best for: owners who want a fuss-free mat with no water, no fridge and no plugging in.
The Green Pet Shop Cool Pet Pad is one of the best-known cooling mats around, and for good reason. It uses a pressure-activated gel that starts working when your dog lies on it, drawing heat away from their body. There is nothing to fill, freeze or charge, which makes it about as low-effort as cooling mats get.
Once your dog steps off, the pad recharges itself after a short while, ready for the next nap. It comes in several sizes from small up to extra large, so it suits everything from a Dachshund to a Labrador. The wipe-clean surface is practical for muddy paws and the odd accident.
What we like: no water or electricity needed, pressure-activated gel, recharges itself, wide range of sizes, wipe-clean surface.
Worth knowing: the firmer gel feel is not to every dog’s taste, and determined chewers should be supervised as with any gel mat.
Specifications:
- Type: pressure-activated gel mat
- Sizes: small, medium, large, extra large
- Power: none required (no water or freezing)
- Surface: wipe-clean
- Available on Amazon UK and pet retailers
Scruffs Self-Cooling Mat
Best for: owners who want a trusted UK high-street brand that is easy to find.
Scruffs is a familiar name in UK pet bedding, and its Self-Cooling Mat brings that reliability to summer cooling. Like most gel mats it is pressure-activated, so it cools as soon as your dog settles on it without any preparation on your part.
It is a good middle-ground choice: comfortable enough to lie on, simple to use and widely stocked at Pets at Home and other retailers. Several sizes are available, and the slim design slips neatly inside a crate, a car boot or an existing dog bed.
What we like: trusted UK brand, easy to buy on the high street, slim design fits crates and beds, range of sizes.
Worth knowing: the gel layer is thin, so it is more of a cooling surface than a cushioned bed, and very large dogs will need the biggest size.
Specifications:
- Type: self-cooling gel mat
- Sizes: small to extra large depending on range
- Power: none required
- Use: floor, crate, car or on top of a bed
- Available at Pets at Home and Amazon UK
Trixie Cooling Mat
Best for: owners after a dependable all-rounder at a sensible price.
Trixie products turn up across most UK pet shops, and its cooling mat is a solid value pick. The self-cooling gel needs no water or power, and the soft-touch surface tends to feel a little more comfortable underfoot than some firmer pads.
With several sizes on offer it works for small and large dogs alike, and the price keeps it accessible if you want to buy more than one for different rooms. It is a sensible default if you are not sure where to start.
What we like: good value, soft-touch surface, no preparation needed, plenty of sizes, widely available.
Worth knowing: as with all gel mats it offers cooling rather than deep cushioning, and the surface can mark if dragged across rough ground.
Specifications:
- Type: self-cooling gel mat
- Sizes: multiple, small through to extra large
- Power: none required
- Surface: soft-touch, wipe-clean
- Available on Amazon UK and pet retailers
Pecute Cooling Mat
Best for: owners on a budget who still want a decent-sized gel pad.
The Pecute Cooling Mat is a long-time Amazon UK favourite thanks to its low price and generous sizing. It uses the same pressure-activated gel as pricier rivals, cooling as soon as your dog lies down and recharging on its own afterwards.
It is a great way to try a cooling mat without spending much, and the larger sizes are well suited to medium and big dogs. The folding design also makes it easy to take to the park, pop in the car or tuck away when summer is over.
What we like: very affordable, good range of sizes, foldable for travel, no water or power needed.
Worth knowing: build quality is not as premium as the leading brands, so it may not last as many seasons with heavy use.
Specifications:
- Type: gel cooling mat
- Sizes: small to extra large
- Power: none required
- Design: foldable for travel and storage
- Available on Amazon UK
Aqua Coolkeeper Cooling Mat
Best for: serious summer heat and dogs that really struggle in warm weather.
The Aqua Coolkeeper takes a different approach to the gel mats above. Rather than a pressure-activated gel, it is an evaporative mat: you soak it in water, wring it out and lay it down, and it cools as the moisture evaporates. This can deliver a noticeably cooler surface, which makes it a strong choice on the hottest days.
It is a premium option with a smart, durable finish and a good spread of sizes. Because it relies on evaporation it works best in a ventilated spot, and you simply re-wet it once it dries out. For owners of heat-sensitive dogs it is well worth the extra outlay.
What we like: effective evaporative cooling, durable premium build, good for very hot days, range of sizes and patterns.
Worth knowing: needs soaking and occasional re-wetting, works best with airflow, and costs more than a basic gel pad.
Specifications:
- Type: evaporative (water-activated) cooling mat
- Sizes: small to extra large
- Power: none, uses water and evaporation
- Best use: ventilated indoor or shaded outdoor spot
- Available on Amazon UK and specialist pet shops
K&H Coolin’ Bed
Best for: owners who want a cooling surface with a little more cushioning.
The K&H Coolin’ Bed is a water-filled cooling pad that sits somewhere between a thin gel mat and a proper bed. You fill it with cold water once, and the body of water helps draw heat away while giving a slightly softer place to rest than a flat gel pad.
It is a tidy option for a regular sleeping spot rather than something to carry about, and the sturdy outer is built to handle everyday use. Older dogs and those who like a bit of give underneath them often take to it well.
What we like: water-filled for a softer feel, good for a fixed sleeping spot, sturdy hard-wearing outer, no electricity needed.
Worth knowing: heavier and less portable once filled, and you will want to check the seal and empty it carefully at the end of the season.
Specifications:
- Type: water-filled cooling pad
- Sizes: medium and large options
- Power: none, fill once with cold water
- Best use: a settled indoor sleeping spot
- Available on Amazon UK
Buying Guide: How to Choose the Best Dog Cooling Mat
What to Look For
Start with how the mat cools. Self-cooling gel pads are the easiest to live with because they need no water or power, while evaporative and water-filled mats can feel cooler but ask for a little more effort. After that, think about size, durability and how easy the mat is to wipe clean, since summer means muddy paws and the occasional spill.
Cooling Mat Types Explained
Gel mats use a pressure-activated gel that cools when your dog lies on them and recharges once they get up, with nothing to fill or freeze. Evaporative mats are soaked in water and cool as the moisture evaporates, which can give a cooler surface on very hot days. Water-filled pads are filled once with cold water and offer a slightly cushioned, longer-lasting cool spot for a fixed sleeping area.
Size Guide
Pick a mat your dog can lie on fully without hanging off the edges. As a rough guide:
- Small (toy and small breeds, up to around 10kg): a small mat suits a Chihuahua, Dachshund or Yorkshire Terrier.
- Medium (around 10–25kg): a medium mat fits most Spaniels, Border Collies and similar.
- Large (around 25–40kg): a large mat suits Labradors, Golden Retrievers and German Shepherds.
- Extra large (40kg and above): go for the biggest size for breeds such as Newfoundlands and Great Danes.
If in doubt, size up. A mat that is slightly too big is far better than one your dog cannot fully settle on.
How Much Should You Spend?
- Budget (under £15): Pecute and similar gel pads — a fine way to try a cooling mat without spending much.
- Mid-range (£15–£30): Scruffs, Trixie and the smaller Green Pet Shop pads — better build and a good size choice.
- Premium (£30+): Aqua Coolkeeper and larger evaporative or water-filled mats — the most effective cooling for heat-sensitive dogs.
Frequently Asked Questions
How does a dog cooling mat work?
Most cooling mats use a pressure-activated gel that draws heat away from your dog when they lie on it, then recharges on its own once they get up. Evaporative mats are soaked in water and cool as the moisture evaporates, while water-filled pads use a body of cold water to stay cool.
Do cooling mats need to go in the fridge or freezer?
No. Gel cooling mats are self-cooling and work at room temperature, so there is no need to chill them. Some owners do pop a gel mat somewhere cool before very hot days, but it is not required. Evaporative mats simply need re-wetting with water.
Are cooling mats safe if my dog chews them?
Cooling mats are designed for dogs to lie on rather than chew, and the gel is meant to stay sealed inside. If your dog is a keen chewer, supervise them on the mat and choose a tougher model, removing it if they start to bite at it so the filling stays intact.
Where should I put the cooling mat?
Place it somewhere shaded and out of direct sun, such as a cool floor, inside a crate, in the car footwell or boot, or in a shaded spot in the garden. Many dogs will choose to use it themselves once they realise it is cooler, so it helps to let them come and go as they please.
When should I see a vet?
A cooling mat is a comfort aid, not a substitute for proper care in the heat. If your dog seems unwell in hot weather — for example heavy panting that does not settle, drooling, wobbliness or collapse — treat it as urgent and contact your vet straight away. Always make sure your dog has shade and fresh water available.
Final Verdict
For most UK owners the Green Pet Shop Cool Pet Pad is the best all-rounder: it needs no water or electricity, recharges itself and comes in sizes to suit any dog, making it about as simple as summer cooling gets. If your dog really feels the heat, the Aqua Coolkeeper and its evaporative cooling is the stronger pick for the hottest days, while the Pecute mat is a great low-cost way to give a cooling mat a try.
