While living in Anchorage, we were blessed with a great video rental place just down the road. There was one scene where the camera crew follwed a native hunter and his dog team going for a Polar Bear. The narrator made a comment about the small caliber 222 rifle the hunter used to avoid damaging the pelt. After spotting the bear, he un-harnessed his dogs and they harassed the bear while leading it back closer to the hunter. Probably around 30 or 40 FEET away he shot it one time through the spine, near the shoulder. The Polar Bear staggered in a half circle and fell down dead!---This film was taken during the 1960's or early 70's. Maybe even before that.
Regardless, that's some nerve. The guy obviously placed much trust in his dogs. Maybe they knew if they didn't do their job right, they would starve, or become the bear's next meal.
