One of my male wolf shepherds was our "wolf in shepherd's clothing"--red and black, thick, thick coat, tho not really long coated, ears nearly normal GSD size, lots of bone, taller than most GSDs, and did I mention beautiful? Definite wolfy temperament, though. And did I mention beautiful? Anyway, some guy walking his female GSD down the highway once stopped and asked me if he could breed her to my boy and said she was in heat. I told him no, that we don't breed, never have, never will... He got so angry, shouting, throwing his arms around, that I just took my boy inside and shut the door. He was so adamant about breeding to my wolfdog (that he thought was all GSD), that I was afraid he would toss his female over the fence. None of my guys were ever outside without me, but I still decided to keep them in the back--we had the front fenced also but could close it from the back.
