My wife and I were looking into maybe adopting Jax. He's 2 years old. In the pics he looks like a dark sable GSD to me. My wife pointed out the white on his chest and is not sure if he's full blooded, or a mix. To me he looks full blooded. Do shepherds sometimes have a patch of white???? Here's some pics of him. Looks like an awesome dog to me. He's house trained, and leash trained. Neutered and all up to date on shots, ect.
