Great option!

We got a new puppy who pees in her crate sometimes. I was looking for a waterproof bed and found this! I put it on over the bed itself, but inside the fluffy cover, so for our puppy she still has the same bed. She peed in her crate this week and I just had to wash the cover of the bedding and not the entire thing. It is soft enough if she peed on her bed late and we didn’t have time to wash and dry it before bed to just take the our cover off and use this cover instead. Really nice quality. Soft and doesn’t feel like plastic.

Waterproof liner for dog bed

This is a great item. It protects the inner part of the dog bed. If there is an accident of sorts, the inner guts of the bed are not penetrated. I wish I would have gotten this sooner. I wouldn't have to have thrown so many beds out.

I misread what I was buying and thought it was an actual bed. But I made it work by buying 4 large bed pillows and stuff them in there. It's perfect for our 100+ pound dog. He laid on it the first night and didn't move to morning. Even though I had to make it into a bed because of my own mistake it's perfect for him

Great Liner

Purchased this along with a dog bed to prevent stains and smells from seeping into the mattress/bed. Have laundered it once and it's working good so far. No stains. No leaks.

Works well

I bought this to protect a new bed from an old dog with accidents. Works pretty good. Liner gets wet thru to internal surface but does not saturate to the foam within. Additionally, if the product had a zipper around two sides instead of one it would be much easier to install on my large 36 x 46 x 6" bed.

This product is NOT waterproof

I used this liner to go around a memory foam med for my Great Dane. She has been having some incontinence issues and while waiting for a new medication to arrive in the mail, we purchased this to protect her bed. She laid on it for one evening after receipt and urine soaked right through to memory foam and ruined the memory foam. I was so disappointed and frustrated. We had spent $30 on the liner and even more on the memory foam.

Waterproof dog bed liner

I purchased an extra Large bed and a extra large liner. But the liner looks twice a big as the bed. It’s ok, better big than too small.

Definitely Waterproof

This has saved my dog beds from my spiteful cat that wants to pee on their beds. I highly recommend this cover it is true to size fit with some stretch to it. Now if they just made them to deter cats from wanting to pee on them they would be golden.
