I bought one of the dog beds from Costco and the other one from Dr. Fosters I believe. I bought both beds for my previous GSD so they are probably 5-7 yrs old. When my current dog was a puppy...she did chew a little on the Costco bed...so I put it away and now that she is older...she love it and the other one. I believe they both are large (costco bed) and XL for the other bed.
