I just went through this same thing. I got my first one (Lady) and around six months found myself looking for another one. I got mine both as adults. They were retired breeding dogs from what I consider to be a responsible breeder. The nice thing is that she knew the personality of both dogs. Lady is a diva and the dominant one, Prince is easy going. They got along great right from the start which was really nice. I find two no more work than one and they are different in so many ways it keeps things interesting. Lady has a playmate which is nice.
