Again, not quite sure, just throwing out a theory.
From what I could tell, the parents had no mix in them but I'm always questioning. However, my coworker has my dogs sister and she looks like a full blooded GSD with no white anywhere! It was only my pup, so I'm not sure where it came from. I'll try and get more information out of the guy I got him from. Thanks!
