I met a GSD a couple of weeks ago that was an adult “black” shepherd. She was solid black, but had the lower half of her legs patterned like a sable, but positioned like a bi. It was very interesting to see. I didn’t ask any questions, because that means I would have to actually talk to someone, but I was very curious how that happened. I know nothing of pedigrees, and my head spins trying to figure it out, so I leave it to the professionals! If I had to guess, I’d say dark sable.
