This multi-use mat is trimmable, machine washable, and proudly made in the USA from recycled materials.

Features & Benefits

Easy To Clean
This mat is easy to clean and is vacuum and machine-washer friendly (see washing instructions below in the "Please Note" section).

Please Note
1) The mat may initially have some wrinkles/creases from being folded and packaged. Over time these will relax out of the material as the product rebounds from being packaged.
2) For best washing results: Hose off or powerwash with a mild detergent, then hang to dry. If machine washing, use a machine without an agitator and wash separately with a mild detergent, then hang to dry (DO NOT BLEACH OR PUT IN DRYER).

- Reviewed in the United States on June 14, 2025Size: 48" x 50"Verified PurchaseI use this as an added layer of protection in the area I use puppy pads for my chihuahua. I don’t wash them, I just change them out every month. Each time I change them out, no break through to the floor. This is my 4th purchase. Worth the money to protect my flooring. They also would be great where water and food dishes as kept as well.

I have purchased two different sizes one size for the whelping box and one size for the playpen. I keep several on hand so they can be changed and the others can be washed.

- Reviewed in the United States on April 11, 2025Size: 48" x 100"Verified PurchaseWorked good. I got the longest one so we could cut it in half and have two mats for our 4x4 whelping box. Our lab had all 11 of her pups on it and no moisture got through it. I haven’t washed one yet, so not sure how it’ll hold up to that. I do wish they had an option for a wider one since it was 4 feet wide, the same as the box. It would have been nice to have an extra inch or two to tuck under the box sides.

- Reviewed in the United States on January 18, 2025Size: 48" x 50"Verified PurchaseThe quality was pretty thick. It was soft. The dark color help to hide puppy urine. I was able to wash them pretty easily and I hung dry them. The texture on the material made it easier for the puppies to grip the floor and walk around a little as they were building their strength and their legs. It fit perfectly on the bottoms of my whelping box. It was great puppy protection from my floors. The appearance is kind of a black gray textured surface. I would definitely recommend this to anyone that is having a litter of kittens or puppies or any kind of animals that are small.
- Reviewed in the United States on August 14, 2024Size: 48" x 50"Verified PurchaseI recently purchased the Drymate Whelping Box Liner Mat, and I couldn't be happier with it! The mat is incredibly absorbent and does an excellent job of keeping the area dry, which is essential when dealing with puppies. The material feels durable yet soft, providing a comfortable surface for the pups.
One of the best features is that it's washable and reusable, making cleanup a breeze. After each use, I just toss it in the washing machine, and it comes out looking as good as new. It's also much more environmentally friendly than disposable pads, which is a big plus for me.
The mat fits perfectly in our whelping box and stays in place, thanks to its non-slip backing. I've noticed that it helps control odors better than other pads I've tried, which is a huge relief.
Overall, the Drymate Whelping Box Liner Mat has been a lifesaver during this busy time with our new litter of puppies. I highly recommend it to any breeder or pet owner looking for a reliable, high-quality solution for keeping their whelping area clean and dry.
- Reviewed in the United States on January 8, 2025Size: 48" x 50"Verified PurchaseI cut this up into a couple of pieces to fit inside a kennel I use for my house rabbit - I used to use newspaper, but who has enough of that anymore! It works great, washes great, dries pretty quickly for rotations, and still seems like new after using it for weeks. The remainder piece I stuck under my cat's litter box for those few times she pokes her butt over the edge and wets the floor - dang her. Great product!!
- Reviewed in the United States on December 7, 2024Size: 48" x 50"Verified PurchaseLove the size and waterproof aspect but its does not stay put. This seems to be an issue for dry mate brand, the back is not very grippy on carpet or hard floor.

5.0 out of 5 stars AMAZING!!
Size: 48" x 100"Verified PurchaseBought to protect my floors against harsh Canadian winters, dogs, a husband and kids. I cut them easily with scissors to fit perfectly to the entry area and then used double sided tape to keep it perfectly in place (just a extra step, this mat lays flat and does not slid) Vacuums easily, and used the Bissell crosswave to wash it as needed. I have now bought 6 of these. One for each entry, two as gifts and two more to line the dog room (yes our dogs have they own room (office space) when we aren't home) These protect the laminate floor and are super easy to clean. I have bought 11 other dog pad/mats type things and these by far are the best!! Wish I found them sooner!! Also the dog hair comes right off with a light vacuum!!!
