If you live where it gets hot, this mat is highly recommended. This squishy mat is much more comfy for an old dog than cooling off on the kitchen tile, and it can be moved anywhere you want to give your dog a bit of cooling comfort.

Summer of 2021, I bought the large mat for my 30lb, 11yo, diabetic spaniel setter mix. We needed something to help keep her comfortable/cool while in the bedroom at night. She has gotten older, and it seemed after getting diabetes, she has become more sensitive to the heat. My dog liked this mat from the get-go, and laid down on it the moment I unwrapped it and set it on the floor. If it is in the room where we are, like the bedroom or the living room, then that is pretty much the only place she will lay.

Please note, the large 20x36 mat is the perfect size to allow my medium-sized dog to stretch out fully on her side or tummy. Getting a larger size means there is more cooling surface, which I consider a plus worth the additional cost.

PROS:
-Can be popped in the freezer to get super-chilled (my dog *loves* it when I do this and rushes over to lay on the mat when I set it down for her). I definitely recommend this for a fast cooling--- just don't leave it in there for a long time and freeze it into a brick of ice. Treat it more like a beer you pop in the freezer to chill fast, but remove before it solidifies. Think 15 minutes and done. On a scalding summer day this gets the mat back to your dog ASAP. This little extra bit of attention and effort is worth it to me to help keep my dog cool.
-Comfortable, soft and squishy under the dog's joints (especially when compared to tile they lay on when they are hot and don't have this mat). This is good for any dog, but great for older dogs.
-Wipes clean easily, good for dog messes like dirt, hair and potty accidents. Mine has endured them all.
-Light and portable, just fold it up and it can travel or just be moved around the house where it is most useful
-Durable! (Disclaimer: No, my dog doesn't chew on things that aren't chew toys. I guess I am lucky.) This mat is still going strong, and still has only the slightest of fraying at the edges. It still cleans easily, which is good because my diabetic dog occasionally "leaks" a bit when sleeping at night. It has traveled well cross country, been in her travel space and at hotels, which provided her a lot of physical and emotional comfort. The mat has not leaked after heavy use over a long, hot summer and fall; nor has the mat leaked after a lot of travel.

CONS:
-Not really a con, but... Be super careful if YOU step on it. It doesn't cause any traction issues for the dog, but I nearly slipped once while navigating on it in a tight area. The gel filling makes this an unstable surface for us humans to step on, without extreme caution.

Love these mats, we buy them every year. The cooling function works as advertised. When it gets warm the dogs just move and it recharges...no mess, sturdy, so worth the price!

I have small dogs that love there space so I got the XL and it was great, dogs loved it.

I like the coolness. I just didn’t like the seam down the middle. Not comfortable for the dog If not for this it could get a 5 star

I'm very impressed with this pad, it fits my dog perfectly as far as size. He's getting used to it. I think I would like to have one for my bed as it seems to really keep cool. I would recommend this item for pet lovers. I live on a boat in San Diego, and it's been a hot and humid summer. I do have A/C, but my dog does enjoy sleeping on it.
