Up here over the last few years there was a very active wolf pack on the military bases next to Anchorage. For years the wolves did not mess with people and their dogs. However, after years of being left to do as they please the wolves learned that they had nothing to fear from the dog walkers on the back roads of the bases.
One wolf would come out to "play" with the off leash dog. As the wolf would run back into the brush the dog would follow its new buddy. Waiting for the dog was usually two to three other wolves. A light afternoon meal was made of the pet in just a few minutes. Once they didn't even wait for the dog to get out of site of its people before killing it.
Last winter they treed a woman out running on the back roads. The wolves were not interested in the dog sitting at the base of the tree. When other runners showed up the wolf moved out of site and the lady got out of there. During this same period wolves were also seen around the new housing areas while kids were outside.
The base told the State that they didn't care to have the State's wolves scaring folks and the pack was killed off as much as possible.
So, for you folks in wolf territory, if they do not out right kill your dog and look to be playing with it, you might want to get your dog to return to you. None of the dog walkers that lost their dogs had any kind of control over the dog. If they had a quality recall trained into the dog they might still have the dog.
Also, if you are faced with an agressive wolf do not run, it will just run you down, hamstring you, and eat you alive. Fight it face to face.
