Besides all the good ideas presented: (lock your bedroom, let the cops search the house, have a good dog, and of course a gun) One thing I would do whether I had a dog or not, is to post at the beginning of your driveway or somewhere where it can be seen when someone drives up is a “Beware of Dog†sign. BG’s just don’t like dogs and will usually look for easier pickings. I like to psych the potential BG’s out.
