The females will not allow the male near her in her den from the time she goes into labor throughout the birthing process. She will growl and he will stay away. Let me say, I do not breed wolves or wolf dogs. It is incredibly hard to find excellent homes to place them in. He keeps a good 20-30' distance between himself and any strangers that come to my property.
Wolves have a high prey drive.
Thus, they are not adaptable to most people's situations. Dogs have the 3 strikes rule before euthanization, but wolves or wolf dogs do not. My wolves howl, but do not bark. If I could fence my entire property for the wolves, when a stranger would come, they would never even know they are here, as they would hide and watch. Granted, my wolf-dog does bark, but these animals will not protect anyone or anything, except themselves, their offspring, and possibly their mates.
