Cooling Mat Review: A Full Summer of Use with a Chow Chow

Bruno is seven, sixty-four pounds, and built like an ottoman with opinions. He is a cinnamon red rough-coat Chow Chow, and once the thermometer in Fort Collins pushes past about eighty degrees he starts panting like he has been asked to jog. By this past May I was tired of watching him lie on the tile with his legs splayed out like a bear rug, and I decided to try an actual cooling mat instead of hoping the floor was doing enough.

In May 2026 I bought the MARUNDA cooling mat in the 36 by 24 inch size. It lived on the kitchen tile by the patio door from June through September, then went into the garage in October with the rest of the summer gear. This is what a full summer with it actually looked like, including the parts that were not great.

How I've Used It

I want to be clear about what I am and what I am not. I am a retired school office administrator who has owned exactly one Chow Chow. I am not a veterinarian and not a professional groomer. Everything below is one dog, one house, one Colorado summer. Dr. Amara Nwosu is Bruno's vet and she makes the medical calls, not me.

The mat is the simplest piece of gear I have bought for this dog in years, which is part of why I liked it. No gel bladder to puncture, no water to fill, nothing to put in the freezer, no cord. It is nylon fabric with a soft filling inside, and it feels cool rather than cold when you put your hand on it. I unrolled it on the kitchen tile in May, and it stayed there until October.

Washing was about once a month, gentle cycle, air dried. It came out of the machine looking the same as it went in, and it air dried quickly on the patio rail. The rest of the time I wiped it down or shook it out. That is the whole maintenance routine. For a household where the dog's coat work already eats a Sunday morning, I appreciated that the mat asked nothing of me.

I should add how I set it up, because I think placement did as much work as the mat itself. The kitchen tile runs about eight feet from the patio slider to the island, and there is a spot about three feet in from the door that catches the cross breeze when both the slider and the laundry room window are open. That is where the mat went. Not in the corner, not under the table, not in front of the fridge where I would step over it forty times a day. In the draft. The first two weeks I did nothing but leave it there and let him find it on his own schedule, which for a Chow means the day he decided it was his idea. He decided on day one.

What the 36 by 24 Inch Size Really Means for a Big Dog

Here is the honest part about sizing. Bruno is 64 pounds with a heavy ruff and thick pants on his back legs. Curled up in his preferred donut position, he fits on the 36 by 24 inch mat with room to spare. Stretched out flat, which he does when it is genuinely hot, his back legs hang off the end and one front paw ends up on the tile.

I measured him properly in June, because I wanted a number instead of an impression. Nose to the base of his tail, flat out and relaxed, he is right about 38 inches. The mat is 36 long. So the overhang is real and it is about two inches of dog on bare floor before you count the paws he tucks. Curled, he occupies maybe 26 by 20 of the surface and the rest of the mat is spare. There is no version of this where a 64-pound Chow uses the full rectangle comfortably at once.

He did not seem to mind. He would shift, replant, and go back to sleep. But if you have a dog who insists on full sprawl, know that a mat this size is a suggestion rather than a boundary. The listing says large and lists a breed recommendation of large, and I would call that fair for a dog that curls. For a dog that sprawls and is over about seventy pounds, I would think hard about whether one mat is enough floor coverage. My neighbor has a hundred-pound shepherd mix and asked to borrow it for an afternoon; that dog had a third of himself on the tile and got up twice.

The mat itself is thin, listed at 0.6 inches thick and 1.5 pounds, so it is not a padded bed. It is a cool surface. If your Chow is used to a soft bolster bed, this is a different category of thing and he may need a few days to decide it counts as a bed. Bruno split his time all summer between the mat in the afternoon and his regular bed at night, and I never tried to make the mat replace the bed. They do different jobs.

How It Held Up Through June, July and August

June was the test. The first genuinely hot afternoon, I think it was June 9 and I remember because I had the sprinkler running, I put the mat down and walked away without saying anything. Bruno came in from the patio, sniffed it once, circled twice, and lay down. He did not get up for an hour and a half. That is the entire review, really. He chose it over the tile, and he kept choosing it.

Through July and August it became part of the afternoon routine. Patio in the morning while it was still cool, inside on the mat from about noon to four, out again in the evening once the shade moved. He would sometimes drag a back leg across it while getting up, which bunched the fabric, and I would smooth it back out. No tears, no seam separation, no flattened spots that stayed flat. I checked the seams at the end of August with my reading glasses on because I half expected the corners to give, and they were intact.

The one thing I noticed by late August was that the cool feeling is strongest when the mat has been somewhere air can move over it. On the tile by the patio door with the slider cracked, it stayed noticeably cool through the afternoon. When I moved it into the carpeted living room for a week because we had company, it was less convincing. That is the fabric doing its job, not a defect, but it is worth knowing where you plan to put it.

For a fair comparison, I did test the cheap alternative first. In the summer of 2025 I bought one of those basic elevated cots, the mesh kind on a metal frame, thinking the airflow underneath would be the answer. Bruno used it about four times all season and then went back to the floor. The mesh was fine, the frame was fine, he simply did not want to be up off the ground. That is an eighty dollar lesson I would like back, and it is why I did not bother with a second cot this year. Some dogs want elevation. Mine wants contact.

He sniffed it once, circled twice, and lay down. He did not get up for an hour and a half. That is the entire review, really.

What the Mat Cannot Do

A cooling mat is not air conditioning and it will not save a heavy-coated dog from a bad decision. I still walked Bruno before seven in the morning and after eight at night in July. I still kept two water bowls, one in the kitchen and one on the shaded patio. I still brought him in when he was panting hard and would not settle. The MARUNDA mat gave him a better place to land during the worst hours. It did not give me permission to be careless. On the worst days, the ones that hit 97 and stayed there, he was inside with the ceiling fan on and the mat under him, and that combination is the honest version of how we got through it.

It also does nothing for the coat itself. A Chow's undercoat traps heat, and no mat on the market changes that. What changed Bruno's summers was doing the coat work consistently, not buying a mat. The mat came after the grooming, not instead of it.

For context, the coat work in this house is a rake and a slicker brush and a dryer on bath day. Sunday mornings on the patio with the rake, twenty to thirty minutes, twice a week in April and May when the coat blows. Five minutes in the evening with the slicker on the ruff, behind the ears, and the pants. Baths about every six weeks in the garage, and a high velocity dryer because three hours of towels and air drying in a damp ruff is how Bruno ended up with a hot spot on his neck in August 2025. That hot spot is the only one he has ever had, and I intend to keep it that way.

I will say the quiet part plainly, because a lot of people buying a mat are hoping it is the whole answer. It is not. If you brought a Chow home in April and did nothing else, the mat would not carry you through August. Bruno's undercoat in May looks like a second dog, and until it is raked out he is carrying a winter coat in ninety degree weather no matter what he lies on. The mat is what he lies on after the raking. That order matters.

If you are looking at a mat as a substitute for any of that, it will disappoint you. If you are looking at it as one more place for a heat-sensitive dog to get comfortable between eleven and four, it earns its spot on the floor.

The Parts I Would Change

The size chart is the main one. The listing calls the 36 by 24 a large and recommends it for large breeds, and for a curling dog it is fine. For a sprawler it is short. I measured Bruno nose to tail base at about 38 inches when he stretches out, and the mat is 36 long. That arithmetic is not hidden, but it is not obvious from the listing either. If I were buying again for a dog this size I would probably buy two and lay them end to end, or buy this one knowing full well that half the dog is off it by August.

Second, the mat slides. On tile it stays put reasonably well, but on the carpet it wandered a few inches every time he got up. Not a dealbreaker, just something to know if your dog does a dramatic exit. The tile in my kitchen has a slight slope toward the laundry room drain and the mat drifted that direction maybe an inch a week, which I only noticed because I was mopping anyway.

Third, and this is on me rather than the product, I should have started it in May instead of waiting for the first hot week. He took to it immediately, but a dog who is suspicious of new things on the floor might need a few days of leaving it out before it becomes normal. A friend of mine has a rescue who will not step on anything that was not there when she moved in, and that dog would need a week of the mat just existing in the room before anyone expected her to use it.

Who This Is For

This mat makes sense for a Chow owner whose dog already seeks out hard cool surfaces in summer. If your dog flops on tile, on concrete, or against the bathroom door in July, he is telling you what he wants and this gives him a better version of it. That was exactly Bruno. He had been using the kitchen floor as a bed since he was three, and the mat did not have to convince him of anything.

It also suits a household that does not want another appliance. No cord, no water reservoir, no freezer space, no gel pack to lose. Wash it once a month and put it back down. If you already do a full coat routine and you are looking for the comfort piece that goes alongside it, this is a reasonable place to spend. And it suits a dog who curls. Bruno sleeps in a donut. He fits. If yours does too, the sizing complaint above does not apply to you.

Who Should Skip It

Skip it if your dog is a dedicated sprawler over about seventy pounds and you want one mat to cover him. You will be buying a second mat or fielding a dog with his feet on the floor, and you should know that going in rather than after.

Skip it if what you are really hoping for is a solution to the coat. A Chow in a Fort Collins summer needs the undercoat managed, water available, walks moved to the cool ends of the day, and shade. A mat is fourth or fifth on that list. Buying it first and hoping is how people end up disappointed in a product that is actually doing what it claims. I did the coat work for about four months before I bought this, and I think that order is why it worked for us.

And skip it if your dog is a chewer. This is fabric with filling. It is not a chew toy and it will not survive being treated as one. Bruno has never chewed a bed in his life, so this was not a concern in my house, but I would not leave it unattended with a dog who destroys things. Same goes for a dog who digs at bedding before lying down, because that front paw work will find the seam eventually.
