I dont think a wolf hybrid is any more dangerous than a rott, dobe, or pit or many other breeds....if they are not trained properly they will kill a baby or bite anyone.
But as any domestic dog, if they are trained properly there is nothing wrong with them. I have seen my BEAGLE snap before I have EVER seen Kenzie (zero's wolf hybrid) snap. My dog has snapped at kenzie for getting to close to her food or chewy and he does nothing. I dont think I have ever seen him bear his teeth once. He is like a big baby.
