I know, most people don't agree with this AT ALL, but Maggie always sleeps outside unless it is really cold out. Boo boo sleeps in the house, in the living room in his dog bed. Autumn usually sleeps inside in the late fall/winter/early spring, and outside all summer. Autumn and Maggie hate being in the house unless it is freezing. I'm not sure why they don't like to be in here, but they beg to go out constantly, so if that's what makes them happy, I guess I'm going to give it to them. They have HUGE dog houses. They are about four feet tall and about 5 feet long. They have two rooms, the front room is glass and they have food in there, and then the back room is supposed to be where they sleep. They usually end up sleeping together in one dog house though.
