I have a 7 year old male black and tan long-hair dachshund (Corky), a 5 year old female red long-hair dachshund (Cyndar Ellah), a 2 year old male Yorkie (Zed), and my roommate's 15 year old cataract-blind male min-pin (Pistol). All but the min-pin sleep with me. I have to lock the bathroom door to have privacy, otherwise they're all supervising.
