I get the question of whether or not my boy is a shepherd all the time. I think a lot of it has to do with his color. He is a sable like your guy. I think that is what throws everyone off.
As far as breeding him goes I personally wouldn't do it unless I planned on becoming a breeder and dedicating a lot of time and energy to it. There is just so much involved. He is very stunning though. Makes me think of my Ammo.
