A cooling mat gives your dog a cooler surface to lie on in warm weather. This guide covers the main types (gel, water, frozen insert and raised cots), the chewing risk that matters most when you choose, the mats we list, and the heatstroke signs that mean you need a vet, not a mat.

The short answer: the CoolerDog Hydro Cooling Mat stayed cold longest in Business Insider’s temperature test but needs its ice sheet frozen first. The Green Pet Shop Cool Pet Pad needs nothing at all, but it is gel filled, so skip it if your dog chews. For chewers, look at a water bed such as the K&H Cool Bed III under supervision, or a raised cot like the Coolaroo. No mat replaces shade, water and a cool room.

How we wrote this: the heat safety advice comes from the AKC (quoting its chief veterinarian), VCA Animal Hospitals, PetMD articles by veterinarians, the ASPCA, the RSPCA, PDSA, Dogs Trust and Humane World for Animals, all linked where they are used and checked on 30 October 2026. Product notes come from the makers’ pages, from Business Insider’s hands-on test (it measured mat temperatures with an infrared thermometer) and from NBC Select’s expert interviews. We did not test the mats ourselves, and we do not show prices or ratings.

Does your dog need a cooling mat?

A mat is one comfort aid among several. The AKC says cooling mats should not be used as a substitute for adequate hydration, sun protection or frequent breaks, and Dogs Trust says to make sure your dog has shade and plenty of fresh water all day. Humane World for Animals lists a cooling wrap, vest or mat as one way to keep a pet from overheating, and PDSA says cooling mats can be useful when travelling on warm days.

Some dogs need more care in the heat. PDSA says flat-faced, overweight, giant-breed, thick-coated, very old and very young dogs are most at risk. The ASPCA says flat-faced pets, along with the elderly, the overweight and those with heart or lung disease, should be kept in air-conditioned rooms as much as possible.

Types of cooling mat

• Pressure-activated gel. Cools when your dog lies on it and recharges when not in use, with no water, freezer or power. Makers say they are for indoor use, out of direct sun.
• Water-filled. You fill it with water, which draws body heat toward room temperature. No gel, but claws and teeth can puncture it.
• Frozen insert. A sheet or pack you freeze first. The AKC notes this is an alternative to chemical gels that an overactive dog could chew.
• Raised cot. A mesh bed on a frame that lets air flow underneath and keeps your dog off hot ground. It does not chill, but there is no fill to leak.
• Fabric mats. Thin cooling fabrics with no fill. In Business Insider’s test they warmed up more than gel or water mats.

Chewers and gel mats

This is the most important choice. In October 2026 the ASPCA published research on 45 dogs with suspected acrylamide poisoning from hydrogel cooling products, including dog beds. It warns that products described as nontoxic or medical grade may still contain very high levels of acrylamide, and says that if your pet uses a cooling pad, you should monitor its use, especially if your dog chews things it should not. The ASPCA did not name brands. PetMD‘s veterinarian author also says the gel in ice packs can be toxic to dogs or cause an intestinal blockage.

So if your dog chews bedding, or you have a teething puppy, avoid gel mats; a trainer quoted by NBC Select says the same. Business Insider’s vet adds that for dogs that chew or eat bedding, any mat can be a choking or blockage risk, so supervise. If your dog chews or swallows part of a mat, call your vet or ASPCA Animal Poison Control at (888) 426-4435, and if your dog shows neurologic signs such as muscle tremors or unsteadiness, the ASPCA says to go to the nearest vet immediately.

Our picks

CoolerDog Hydro Cooling Mat: stays cold longest

A water cushion and a frozen ice sheet over a thin foam insert, 18 by 23 inches per mat; mats snap together for bigger dogs, and the cover is machine washable. Business Insider named it the best overall after leaving it in a 95 degree sunroom, where it stayed cold for 7 hours. The catch: you must freeze the ice sheet first, and assembly is required.

The Green Pet Shop Cool Pet Pad: easiest to use

A pressure-activated gel pad that the maker says cools for up to 3 hours and recharges after 15 to 20 minutes off. Business Insider measured only 2.8 degrees of heat transfer and named it the best budget pick, but it is for indoor use, has no nonslip bottom, and the maker says not to leave a dog that chews alone with it. Not for chewers.

K&H Cool Bed III: water instead of gel

A water-filled bed in three sizes up to 32 by 44 inches, for indoors or shade, under 100 F. Business Insider measured just a 3.6 degree rise after a 30 minute lie-down, though it holds coolness less well than gel. K&H says to keep nails trimmed to avoid punctures, never to use it in direct sun, and that it is not intended to be a life saving device.

Coolaroo Original Elevated Bed: raised cot for outdoors

A knitted mesh bed on a steel frame that lifts your dog about 8 inches off the ground and hoses clean. NBC Select’s tester found it kept their dog off warm surfaces. It does not chill like a mat, but there is no gel or water to leak, which makes it a sensible choice for shaded patios. Assembly is required.

How to use a cooling mat

• Keep it out of the sun. The Green Pet Shop and K&H both say not to use their mats in direct sunlight.
• Put it where your dog already rests, in a shaded or air-conditioned spot, with water nearby.
• Watch the first few uses, especially with a young dog, to see whether they try to chew or dig at it.
• Check for damage before each use and stop using a mat that is torn or leaking.

Heatstroke: when a mat is not enough

Heatstroke is an emergency. VCA calls it an immediate medical emergency, and PetMD‘s veterinarian author says to take your dog to an emergency vet straight away if you suspect it. The AKC lists early signs such as heavy panting, rapid breathing, excessive drooling, bright red gums and tongue, and skin hot to the touch; Dogs Trust adds lethargy, wobbliness, vomiting, collapse and seizures. If you see these, move your dog somewhere cool, start cooling them with water as your vet or the sources above describe, and call your vet on the way. The AKC says that even if your dog seems to recover, a vet visit is essential. Do not cover your dog with wet towels, which VCA and the RSPCA both advise against, and do not rely on a cooling mat to treat it.

FAQ

Are gel cooling mats safe for dogs?

For dogs that do not chew, used as the maker says, many owners use them. But the ASPCA’s October 2026 research found some hydrogel cooling products labelled nontoxic contained high levels of acrylamide, so supervise use and choose a non-gel mat for chewers.

Do cooling mats prevent heatstroke?

No mat can promise that. The AKC says mats are not a substitute for water, shade and breaks. Keep your dog out of the heat, and treat heatstroke signs as an emergency.

Should I put a cooling mat in the freezer?

Only if the maker says so. CoolerDog’s ice sheet is meant to be frozen; K&H says never to freeze the Cool Bed III. Check your mat’s instructions.

Can I use a cooling mat in the car?

PDSA says cooling mats can be useful when travelling on warm days, but never leave a dog in a parked car, and The Green Pet Shop says not to leave its pad in a hot car. For car safety, see how to travel with a dog in the car.
