My wife shot a small buck several years back at last light on a cold October evening. We got him gutted and strung him up by his back legs about 6 feet off the ground on our meat pole just outside of camp. Skinned him and covered him in a full body game bag, with our plan being to take care of butchering him in the morning when we had better light.
When we were walking back to him early the next morning, something looked odd about the game bag from a distance. It looked tattered and was blowing in the wind toward the portion of the deer nearest the ground. As we got closer, it became clear that both front legs had been ripped off and were nowhere to be found. You could also see scratch marks on the torso and head where something had been trying to pull the rest of it down. We were able to salvage the back half of the deer.
A week later, something savagly mauled my neighbor's St. Bernard and he had to be put down.
This was between Springdale and Chewelah, probably 7 years ago.
