We have a nice puppy from MI. He is West German Working Lines.
He is an active dog and a great house companion. We train him in SchH & he is a certified ADC (accelerant detection canine) but just a big marshmallow around the house. I would recommend you talk with his breeder Lisa Clark
Zu Treuen Händen Working German Shepherd Dogs in southern MI. I think she may be planning a litter for this coming spring.
I don't think there is any problem with a working line dog being in a family home as long as it's an active home (probably good for most GSDs). When you talk to a breeder, be realistic as to what kind of activity you can offer and what plans you have. This helps them decide if their dogs are a good fit. Honesty is the best policy. Remember it's a 12-15 year commitment.
