I purchased 2 of these for my standard poodle's bolter beds. Roxy had random episodes of vomiting, not necessarily a lot, but bile reeks after a short while. Machine washing the beds was a real pain, grit everywhere to clean afterwards. I purchased 2 of these liners, and bought 2 new bolster beds. I've had these since 2022, and they are still like brand new. *OF NOTE - Roxy gets very excited and does this crazy digging thing every evening. I mean she could dig to China. When she's done this on my bed, she's damaged the sheets. But these covers...like I said, they look brand new, No signs of even a snag! The bolster beds I bought at the same time as these covers (separately) in 2022 also look brand new. No exaggeration. The liners have retained their waterproofing properties, 100% Pro tip - because they are waterproof, when you wash them (they machine wash beautifully!), the liner inside stays wet, like the liner on a mattress cover does. After I take them out of the washer, I turn them inside out and dry the inside liner with a hand towel as much as possible. If the weather cooperates, I take them outside and drape over a chair. If not, I put them in the dryer on low after wiping off the excess water, and I turn them back and forth, right side out, inside out, etc. It sounds like it would take forever, it really doesn't. But it does take a few hours overall, so if you don't want to chance it for even that time (I don't!), I would buy a second liner for backup. I do this with my mattress protectors, too. Roxy doesn't vomit much after going to a hypoallergenic diet, but Murphy's Law says she will if there is no liner on her bed. Plus, I love it that her beds still look new, I don't want any dirt on them. Short story long, I love these, they last forever, but if you have a dog who chews, teeth are far sharper than claws, and they go in both directions at the same time, so who knows on that. They fit perfectly, are a smooth texture, so Roxy occasionally kicks her blanket off and likes to lie on it as is. So does the cat. Of course.

My one dog has an incontenance issue at night and wets her bed. Putting this cover on the bed has made a world of difference. It traps the urine from leaking into the foam under it. I recently ordered another cover, but got one size too large, but am making use of it anyway. I highly recommend this cover if you have a need to waterproof your dogs bed.

Looks sturdy but dogs chewed a hole through the cover and the dog bed. Disappointing.

One of our fur babies has always had some bladder issues which comes and goes. This has been perfect for her beds. I got multiple sizes for all the beds and I highly recommend this product. It keeps the cushioning in good shape and makes things easier when it comes to washing the bed and the cover!!!

My cat peed on this a day after I purchased. I suspect between the "waterproof" blanket on top of the cover (purchased at the same time), it blocked most of the wetness, but enough seeped through that I had to wash the blanket, waterproof cover and the brand new dog bed too. One of my dogs likes to scratch and nest in the dog bed, so it won't be long before I find out just how durable the cover is. On the bright side, it was a perfect fit for the dog bed I purchased. In hind sight, I should have just bought just 1 to try it out before buying a second.

Durable

It has held up to many, many washings so far. No scratches. No damage to the liner. No leak through. I would buy again if needed.
