He wasn't thin in those pictures, they are old ones, because I'm the worst when it comes to taking pictures. It's still hard to tell by looking at him, because he has a thick coat, but when I pick him up, it's obvious he has lost weight.

Yes, I tried the thin, foam beds for old or injured dogs. He glared at me.

Well, it's nice to know, in a way, that other people's dogs have done the same thing. Guess I'll just let him be, nothing I can do about it anyway. Weird old dog.

Thanks for the input.
