When you're out in the wild, there's always the risk of encountering dangerous animals. Whether it's a omnivore like a bear, a carnivore like a wolf, or even an herbivore like a moose, wild animal encounters are always a potential threat on the homestead, wilderness bug-out, or even just a run of the mill hike or camping trip.
Thankfully, even predators generally want nothing to do with humans and would much rather avoid us altogether. However, if they are especially hungry, agitated, diseased, or have learned to associate humans with food, they are more likely to engage you. Sometimes, of course, we don't know exactly why an animal became aggressive in any given case, so it's important to learn the basics.
