Dogs are all about dominance and hierarchy. Sleeping on higher ground is something that a more dominant dog would do and you don't want to give your dog the wrong impression. You're always better off by putting down your dog to make it the beta in your "flock". No violence/beating necessary, just small everyday things like making sure it never sleeps on couches/chairs, always eat before it does, walk in front of it in doorways etc. There's more to it but by assuring that the dog consider you the leader you usually get rid of some annoying behaviors and also makes it easier to train.
yeh, i see your point
but im not really about establishing dominance over my dog, i dont even like that word
i consider her more of like a friend, maybe a retarded friend........i cant tell that with my dog ( i dont even like saying MY dog ) that her sleeping on the bed is more about affection......you can tell by the way she cuddles into my girlfriend or my stomech like she is being protected
but i understand that with some dogs, if you dont establish dominance, they will start doind destructive shit and walkin gall over you
i just dont really witness it much, because there is just an implied dominance, she knows i am a male and knows she is weaker then me........she fucks with my GF (who is the true owner of the dog) a LOT more, casue she is a girl
