  • Waterproof dog bed liner works perfectly.

    By on

    I had ordered 2 of the waterproof dog bed liners. One was regular like this and the other was quilted and a little more expensive. I loved both of them so much, I ordered 3 more larges, 2 XL, and 1 medium. I received one that was not stitched correctly, but Chewy immediately sent me out a replacement. This is the best waterproof bed liner for dogs I have found. It actually works. But best of all, Chewy is probably the best company I have dealt with. Chewy's customer service people are unbeatable. They are courteous, helpful, friendly and do what they say they are going to do. Thank you.

  • Well made product.

    By on

    Purchased this liner to complement the therapudic dog bed for my dog recovering from knee surgery. The dog bed I recently purchased has a bed cover that is not waterproof so I wanted protection for the dog mattress from accidents. I'm please to say that this 4Knines cover is 100 percent waterproof; and best of all, it is a soft and quiet material in a neutral color. The size I ordered is bigger than the mattress, but I roll in the excess and it neatly tucks into the outer cover. Easy to take off and put back on. The liner has been machine washed and dried twice, once before use and once to freshen up. It came out perfectly fine each time. I definitely recommend this product.

  • Terrible dog bed liner

    By on

    I purchased one of these for my 15 year old male who's been dealing with a pretty severe case of urinary incontinence. This is one of the worst bed liners I've ever purchased. While not as bad as others on the market with interior linings that starts to flake off on the inside - this liner is NOT waterproof and the zipper fell off after it was washed twice. Do not waste your $ on this horrible product.

  • Nice bed liner

    By on

    Very nice line, more like fabric than plastic. Nice enough to use as cover!
