Major's collar is always on him. In my situation, it has to be. Alot of people think its safer to have a collar on a dog 24/7, and some people don't. The hazard with keeping it on him while you're not home is it could get caught in a crate or something around the house. You could give your house a good check for things it could get caught on, because you never know. But I still think its safer to keep one on him as much as possible.
