Welcome! You came to the right place.
I love all lines of German Shepherds, as long as they are a good example of the breed.
Watch out for backyard breeders, also known for creating the American "pet-lines." Not saying pet quality GSDs are bad, just be careful.
I got my first GSD from a BYB, and though I love him, he developed extreme Fear Aggression. I got him at four months old, the breeder failed to socialize him before this point.
My more recent GSD is from DDR and West German show lines. He is a fantastic example of the breed. It also has a lot to do with the breeder, she's great and truly cares for her dogs.
