Lucy is definitely, definitely a cuddle bug. She sleeps with me at night and doesn't notice if I roll on her, or roll her into a completely pretzel position, if she's upside down, if I'm on top of her, or if she's under mounds of blankets. She loves the spot on the back of my knees when my legs are folded, too.
Millie is a velcro dog but doesn't like when I move a lot. I pick her up and cuddle her and we lie down together cuddling and completely relaxes and/or falls asleep, but she doesn't stay up on my bed all night or on the couch with me if I move or the bed moves.
