My dogs were bred to sleep on their dog beds, of which they have many.
A friend of mine had two rescue greyhounds. He lived in a relatively large house and his living room had three couches. I went to sit on a couch and he says, "not that one." so I move to a second couch and he says, "not that one, either." After sitting on the third couch, the two greyhounds came in and each took one of the other two couches.
BTW, these were the laziest two dogs that I've ever seen. Another friend of ours has a rescue greyhound, too, and it's also slow and lethargic acting. Either greyhounds are lazy by nature or they've set aside the running after retirement.
