The Sault Star has for years offered a reward for a confirmed report of an unprovoked attack by a healthy wolf on a human being. Never had to pay it out. Of course, every year we hear a few stories of dogs attacking and even killing children or adults. Dog packs are the thing to fear, not wolf packs.
You're absolutely right, FF, when you get a dog, you've got a pack, and you'd better be the alpha. Keeper, our late lamented sod, once growled at our niece, a toddler at the time. David (my husband) pounced on Keeper, hauled him up off the ground, holding him by the skin on the sides of his neck, shook him and growled, then threw him down. This took about three seconds. The next time my niece came into the room, Keeper got up and left. He wouldn't even look at her thereafter for the remainder of the visit.
