I once read that when Jennifer Aniston started dating John Mayer, her dog took an instant dislike to him. As anyone who's kept up with the Aniston drama knows, John Mayer ended up being a disappointment to her. After she broke up with Mayer, she supposedly said that she would begin judging her boyfriends by her dog's reaction to them. Do you think that dogs are good judges of people and perhaps have instincts that many humans don't in these situations?
