My Papillon LOVES to sleep perched on top of things like a cat. Everything form the back of the sofa to the highest pillow on the bed to his dog bed which is sitting on TOP of a dog crate--the list goes on and on! I don't personally mind, but I did hear that letting them be up high can spur a dominance issues between you and the dog or give the dog some sort of alpha complex. What are your thoughts on this? Do your dogs do this??
