You don't say what part of Tenn you live in. I live in north Georgia and my two boxers are inside dogs. When I am not home they are in the house, we let them out into a large fenced in back yard (about half an acre) and after about twenty minutes of running an jumping and playing back there they are at the door knocking to come in. Kiki the male will go out and lie on th eporch for a while, but he doesn't like to stay out very long. Foremost in this conversation is that boxers are very social dogs who need and crave human companionship.
