Excuse my stupidity, I can't imagine how you'd get a wild wolf to mate with a "domesticated' GSD in the first place. I visited friends in rural Minnesota ages ago who had a wolf hybrid. The biggest, meanest dog I ever saw. The test whether or not the dog stayed in the house, while I was there, was his first reaction to me. Great. Loving dogs, and never being afraid, I walked right in and was greeted with a whine, circles, and lots of licks. I had never had a dog sleep on my bed before, and I remember kicking it all night without any reaction. It started growling and barking when a neighbor came home late and I clearly remember yelling "shut up" and it laid right back down next to me. Looking back, I can't believe I took that chance.
