As to the Canaidian ; "Carnegie died as the result of a violent predatory attack, either by wolves (Canis lupus) or an American black bear (Ursus americanus)" seems they just dont know...
Same for the attack in Alaska;
"The autopsy concluded that Candice Berner was killed by animals, the Alaska State Troopers said. The agency's chief said the autopsy could not determine for sure if wolves were responsible but it ruled out other causes of death. "
Im a Wolfer here in a Game unit the size if Indiana. I know fellow Wolf hunters and keep up on the latest among us, in our various doings in each village, as to Hunt Wolves, we follow Caribou herds and work out of the villages that are closest to the Herds. (Gas, parts, repair)
The last person Killed up in NorthWest Alaska was my Father in Laws first Father in law, Panekok Sampson. He died of the Rabies that the Wolf had that attacked him in his Dog lot and that was about 1943 or so.....
My father in law grew up in dogteam.Hunting days, born 1903, and that was the only Wolf attack he had ever heard of. Those men hunted hunted hunted, and would have at least had a story or two.....
In Days of Old here in the Arctic, Ferral Dogs were the "Ultimate Disaster", especcilly in packs or loosed teams.....as they knew where the camps were, didnt fear people and if hungrey enough, would tear you apart and eat you. Little children were grown up with such storys
