I'm not sure what's wrong with this dog

I have two dogs. In the South, they say that one dog is family, two dogs is dogs. I think that might be right. Sadie the Auxiliary Back-up Dog, is small and likes her bed:

Jeb The Wonder Dog, on the other hand, has no bed and sleeps where he likes. On occasion, though, he likes to take over Sadie the Auxiliary Back-up Dog's bed:

Obviously, the bed is too small for him. It can't even be comfortable. I don't know why he does this. But he does.
