More likely the bear's after the sled dogs food. I killed one in my feed shed. Have shot 3 in my yard, the farthest about 20 yards. Yeah they're there and if they learn you provide chow you have a problem. We had a large grizzly that regularly patrolled the tree line 50 yards from our cabin but he never gave us a problem. I reiterate, only once have I felt endangered by a bear, and then I was between her and her cub. Two friends of mine were charged by grizzlies, if George hadn't had his rifle in his hand he'd have been dead, Larry made it to his truck and grabbed his pistol. Yes things happen, but not all that often. Walk loudly and carry a big gun, but you needn't obsess.
