Summer heat is one of the most underestimated dangers for adventure dogs. Surfaces in a parked car or at a sun-exposed campsite run far hotter than the air, and dogs shed heat much less efficiently than humans. A cooling mat is the lowest-effort piece of gear that helps during long drives, camp setups and after-hike recovery. Below are six options, compared strictly on what their manufacturers publish.

How we chose these cooling mats
- Cooling mechanism that works without refrigeration: pressure-activated gel or phase-change material, no water-fill chambers that leak
- Chew resistance: a punctured gel mat leaks, and no manufacturer here sells one as chew-proof. Treat every mat as supervised-use gear
- Sizing matched to actual dog body length: too-small mats cool only part of the dog and provide no relief
- Travel-friendly form factor: rolls or folds for car, crate, or pack transport

1. The Green Pet Shop Cool Pet Pad: Best overall
The Green Pet Shop Cool Pet Pad is our overall pick. It uses a gel that activates under the dog’s body weight, and the manufacturer states it needs no water, refrigeration or electricity, stays cool for up to 3 hours, and automatically recharges after 15 to 20 minutes of non-use. The Green Pet Shop covers it with a 12-month warranty and does not publish a lifespan figure beyond that.
Sizing matters here. The Green Pet Shop publishes five sizes with weight guidance: Extra Small 11.8 x 15.7 in (0-8 lbs), Small 15.7 x 19.7 in (9-20 lbs), Medium 20 x 30 in (21-45 lbs), Large 23.6 x 35 in (46-80 lbs) and Extra Large 27.5 x 43.3 in (80 lbs and up). Size up if your dog is between sizes, because a mat that is too small cools only part of the body.
Pros: no water, power or refrigeration needed, lightweight for travel, wipes clean
Cons: premium price, and not chew-resistant, so remove it from teething or destructive chewers
2. Arf Pets Self Cooling Mat: Best budget
If you need cooling on a budget, the Arf Pets mat uses the same style of pressure-activated gel as The Green Pet Shop at a lower price. We could not reach an Arf Pets specification page to verify a lifespan or cooling-duration figure, so we are not publishing one. Owners generally report budget gel mats developing uneven cooling sooner than premium ones. For occasional use on road trips and hot days, it is a reasonable buy.
Check the current listing for available sizes, since the range has changed between production runs. Like every gel mat here, it will leak if punctured.
Pros: affordable, works without refrigeration
Cons: no manufacturer specification we could verify, and gel mats at this price commonly develop uneven cooling zones over time
3. K&H Pet Products Coolin’ Pet Pad: Best for large dogs
For big dogs, gel mats often run too small. The K&H Coolin’ Pet Pad is water-filled and comes in four sizes: Small 11 x 15 in, Medium 15 x 20 in, Large 20 x 36 in and X-Large 27 x 38 in. The X-Large gives large breeds like Labradors, German Shepherds and Bernese Mountain Dogs a full-body surface.
The water-fill design has trade-offs. Filled with water the mat is heavy, which makes it less travel-friendly than a gel pad. For stationary cooling at home or base camp, the size range and easy-clean surface are what make it the big-dog pick.
Cooling is most effective when the pad sits on a hard floor or in a crate rather than on carpet or grass, which insulate. Note K&H’s own framing: because the pad needs no refrigeration, they state there is no time limit on how long it stays cool in use, and that it works by wicking heat away and settling at ambient air temperature. It is not a chilled surface.
Pros: scales to large breeds, easy to clean, no time limit on use
Cons: heavy once filled, and cooling depends heavily on the surface underneath
4. Ruffwear Swamp Cooler: the one that is not a mat
A correction worth stating plainly: Ruffwear does not sell a cooling mat, and does not sell a vest-and-mat combination. The Swamp Cooler is a vest. We are keeping it in this guide because it solves the problem a mat cannot, cooling a dog that is moving, but it does not belong in a mat comparison without that label.
Ruffwear specifies a three-layer construction: a bluesign approved polyester air mesh outer, a polyester felt middle layer, and a bluesign approved dry-weave polyester mesh lining, with ITW Nexus Waveloc side-release buckles and YKK Vislon zippers. The light-coloured fabric reflects solar radiation, and soaking the vest activates the evaporative cooling.
On re-wetting, Ruffwear’s own instruction is simply to soak it, put it on the dog, and re-soak it when it dries. They publish no fixed interval, and the honest reason is that evaporation rate depends on humidity, airflow and temperature, so any specific hourly figure would be invented.
It comes in six sizes, XXSmall through XLarge, covering 13 to 42 inch girth.
For complementary safety gear when your dog is in the water during summer travel, see our best dog life jackets guide.
Pros: works while the dog is moving, which no static mat does, with reflective trim and a well-documented build
Cons: it is a vest, not a mat, so it does not replace a resting surface. It is also the most expensive item here, and evaporative cooling does far less in humid air
5. Petmate Aspen Pet Cooling Bed: Best for crates and carriers
If most of your cooling needs are inside a crate, carrier, or kennel (during car travel, at vet visits, or while crated at home), the Petmate Aspen cooling bed is sized specifically for these enclosed spaces. The contoured edge prevents the mat from bunching against crate walls (a common problem with flat mats that leads to gel pooling and uneven cooling).
We could not reach a Petmate specification page to confirm the gel formulation, the sizes or the dimensions, so we are not stating that it matches our top pick’s mechanism or publishing measurements for it. What is consistent across listings is a bed-shaped cooling pad with a low bolster edge, which suits dogs that circle and settle rather than sprawl. Check the listing dimensions against your crate before buying.
For travel crate compatibility, see our best collapsible dog travel crates guide for crates that pair well with cooling beds.
Pros: crate-friendly shape with a bolster edge
Cons: smaller usable surface for dogs that sprawl, and no manufacturer specification we could verify
6. Chillz Cooling Mat by Hugs Pet Products: Best for chewers
No cooling mat here is chew-safe, and none is sold as chew-proof. The Chillz is the one most often described as having a tougher outer shell, but we could not verify a manufacturer puncture-resistance specification, so treat that as owner reporting rather than a tested claim.
This makes it the better choice for puppies, teething dogs, or dogs who fidget when bored. Adult destructive chewers can still ruin it, so for known chewers we still recommend supervised use only.
Pros: owners commonly report it standing up to mouthing better than thinner mats
Cons: not chew-proof, and no manufacturer specification we could verify
How to use a cooling mat safely
A cooling mat is a supplement, not a substitute for proper hot-weather safety. Even with the best mat, you still need to:
- Watch for overheating signs: excessive panting, drooling, lethargy, glazed eyes, vomiting. Heatstroke can kill a dog in under an hour.
- Provide cool water alongside the mat: see our guide to collapsible dog water bowls for portable hydration on the road
- Place the mat on a hard surface: never on carpet, grass, or thick bedding (these insulate and prevent cooling)
- Keep the mat out of direct sun: a gel mat left in direct sun absorbs heat and stops helping
- Check the mat surface temperature first: if you can’t comfortably keep your hand on it, it’s not ready for your dog
When NOT to use a cooling mat
Cooling mats are designed for healthy adult dogs. Avoid them for:
- Puppies under 12 weeks: they regulate temperature poorly and can become too cold on gel mats
- Senior dogs with circulation issues: consult your vet first, as cold mats can affect blood flow
- Dogs with hairless or thin-coated breeds: need monitoring; some breeds chill too easily on cooling mats
- Dogs recovering from surgery: follow your vet’s heating/cooling instructions exactly
What about DIY alternatives?
Frozen water bottles wrapped in a towel work in a pinch but cool unevenly and risk cold injury on direct skin contact. A wet towel laid flat under the dog works briefly and warms quickly. Both are fine as improvised measures and neither is a substitute for shade, water and stopping the activity.
FAQ
Do cooling mats actually work?
They help, but manage your expectations. None of these manufacturers publishes a verified temperature drop, and K&H is explicit that its water-filled pad works by drawing heat away and sitting at ambient air temperature rather than chilling below it. A cooling mat gives a dog a surface that does not trap body heat the way bedding does. It is not air conditioning and it is not a treatment for overheating.
How long does a cooling mat stay cool?
The Green Pet Shop states its Cool Pet Pad stays cool for up to 3 hours and then recharges automatically after 15 to 20 minutes of non-use. K&H states its water-filled pad has no time limit in use because it requires no refrigeration. Figures vary by manufacturer, so check the specific product rather than assuming a category norm.
Can I put a cooling mat in the freezer?
No, not for most gel mats. Freezing can damage the gel structure and cause uneven cooling or ruptures. Read your specific mat’s instructions, but generally gel mats work best at room temperature without pre-cooling.
Will my dog actually use a cooling mat?
Most dogs adapt within 1-2 introductions. Place the mat in a familiar resting area and let your dog approach it. Don’t force a dog onto the mat; if they’re not interested, try a different texture (some dogs dislike the rubbery feel) or move it to a cooler location.
Are cooling mats safe for crate use during car travel?
Yes, with the right form factor. A crate-shaped pad suits smaller crates and a flat gel mat suits larger ones. Make sure the dog has water, the crate is well ventilated, and the car itself is climate controlled. A cooling mat does not make a hot parked car safe, and never leave a dog in one.
