I couldn't vote because all of my dogs have different sleeping preferences.

Nanook usually sleeps (night time & long naps) on the floor and takes shorter naps on his beds. (He's too old to jump up on furniture and I don't want to lift him up in case he tries to jump off while I am sleeping & injures himself)

Raustyk's sleeping spot is the couch, theres no doubts about that one. lol Of course she will fall asleep with me on the bed but she's on the couch when I wake up. And if she sleeps when I am not sleeping it is always on the couch.

Kaige.... he sleeps all over the place. lol For naps he usually sleeps on the floor. Longer naps & bed time he moves around all night, my bed, his beds, the floor, his crate. He can never stay still for long. He even moves a LOT when he is sleeping.
