My dogs use the Amazon Basics Donut Pet Bolster Faux Fur Bed every night, and I only wash it every other month. Even with that kind of regular use, it’s holding up very well. It doesn’t look quite as fresh as when it was new, but it’s still decent and comfy for my pets. The bed is soft and cozy, and my dogs love curling up in it. For the price, it’s a great, durable option if you want a comfortable pet bed that lasts.

My pets love it.

I bought this as a replacement to another donut bed that I had had for my dog. He is a 20 pound Jack Russell Terrier. This bed is in his crate. He loves his bed. Not only does the dog, but I also have several cats and during the day when Riggs is loose my cats will go in his dog crate and sleep in the bed. I have had the bed for almost a year now and it’s holding up great. Actually over the weekend I did have to wash it because it looks like he got sick and spit up in his crate. Came out of the washer and dryer great.
