When I was away at college, i lived with 2 guys and one had a dog called Rudy. He was a sweet big brown dog, but he loved to come into my room if the door wasn't closed and chew up my unmentionables. He'd also hump my llama poncho if i wasn't careful.

I learned to keep my door shut -- maybe the baby gate to the kitchen is a cheaper idea than a crate since bear is such a big dog? Its likely easier than trying to get chad to keep the door closed
