Questions about animals likely to be encountered outdoors, whether from the perspective of food (hunting, preparing, eating), shelter (skinning), for avoidance (bears, lions, other dangerous animals), or enjoyment (bird and other animal watching, care, understanding of behavior).
Wild dogs appear to be dangerous. Should I be running if I come across one, or should I stand fast and defend myself? They are a social animal, so they will be in a pack almost all the times.
Some animals are big and dangerous and, when hungry, may realise that humans contain a pretty decent amount of meat. I've never hiked in such areas, but they do exist. Photo from Wikipedia, CC-BY-...
