I always thought my GSD was Black and Tan, the breeder also told me he was. I'm not 100% sure now. I saw some pictures of Patterned Sables and it made me think that maybe Harley was that; You can't tell if you look at a picture of him, but he has tan hairs underneath the black, and black hairs underneath the tan. I don't know if this is typical for Black and Tans? I was just curious.
