Working Line

Hello dear ones, I would like to know something from the pack knowledge.🐕‍🦺🐕🐩🐶 I am the owner of a beautiful German shepherd dog from the working line. She is my first dog - and I love not having a standard family dog - even though I like all dogs, the challenge that comes with a working breed line is exactly what I was looking for. So I enjoy giving her a fair share of her breeding. Now to my question - Is there near Neukölln a club that is specified with working lines? The little one comes from a breeding line for protection dogs. Here video of her father: https://youtu.be/DX9EaVw5SPw I would also be very happy to get in touch with one or the other dog owner who knows about working dogs. Kind regards Julian
