Soft and loved by dog. However after 2 years of washing every other month, it exploded in washer clogging drains and making mess.

Great, comfy bed - so good I bought 2!
Size: 23 in, Size: 23 in
My dog loves this bed, I have one at home for him and one in my office at work (in pic). He sleeps so soundly on it. He’s about 7 lbs and it’s a great size for him, he likes to stretch out when he sleeps. It’s a simple, comfy bed good for dogs about 5-12 lbs. You may want to go one size bigger if your dog is 13-22 lbs.
