Ours are allowed to sleep wherever they want (well, S'mores...Livi's 8 week old puppy sleeps in his kennel next to our bed). Harley normally sleeps in the living room and the other three used to always sleep with me and my husband. But in the past couple of months, Huckleberry has become very close to my 6 year old daughter and he now only wants to sleep with her. Livi and Izzy still want with mommy and daddy, though.
We do not have any aggression or dominant issues with any of them.
