I'm in the early stages of starting to look for a puppy, or more importantly a good breeder in Maryland or PA. I know a little about GSDs but nothing about buying a puppy or the differences between show line and working line. I live on a large farm and am a very active person. The dog would not be left to roam on it's own under no circumstances unsupervised. My ideal dog would be one with a medium/more relaxed energy level with an affectionate and playful temperament. I am around the farm most of the time and if I'm not my husband is so the dog won't be left alone often. We have lots of different people and dogs constantly coming and going on the farm so it would have to be a friendly confident dog. We wouldn't be doing any kind of protection training, showing, or things of that nature but I would like to possibly train it to shed hunt so tracking ability would be a plus. I absolutely love the GSD I have now and I believe she is a working line dog but she was adopted so I do not know for sure. Any advice or information is very much appreciated
