Dear Dog Lady: I've been with my current boyfriend for six years, and we've lived together for two. At my parents’ house, I have a wonderful black lab named Buddy. He was very understanding when I had to pick up and go to college. I know Buddy is happier at home with the other dogs than he ever would be in the city with me, but I would like to get another dog.My concern is how to convince my boyfriend this is a good idea.
