When Hailey Morinico observed a giant bear fighting with her family dogs from the top of a wall in their backyard in southern California, she didn't hesitate.

When a bear feels threatened, it may 'act' aggressively in response to the perceived threat. A mother bears with cubs, a bear guarding a food supply, or an unexpected encounter are examples of this. When a bear becomes aware of you, the closer you approach it, the more likely it is to respond defensively: it may snap its jaws or slap the ground with its front paw while blowing and snorting, and/or lunge or "bluff charge" toward you in an attempt to persuade you to go.
