I bought a large Organic Bumper Bed for my Golden/Chow mix adoptee. After having a huge tumor removed from his side, he's doing very well on chemo and loves his new nest. The only problem is that my other dogs (two Chihuahuas) and cats think it's pretty great, too. Since Flanagan is too polite to chase them out of his bed, I have to remove them for him. I think the bed should come with paw-print recognition feature that would only allow the authorized user into the bed. (Oh well...)
