I get that ALL THE TIME, lol. I've had a few people know that he was a GSD though. One guy at a pet store was surprised when I said he was a GSD, he said but he has so much black on him...
A lot of people seem to get thrown off because he's so dark and because he's a long coat... I've been getting asked more and more if he's a Belgian Shepherd.
One lady thought he was a Rottweiler mix, really??
