Here is a scenario:
You are a licensed carrier out for a walk on your own, maybe in a neighborhood park or on a hiking trail. You come across a huge, vicious dog (such as a pit bull) without a leash on, and running at you, obviously wanting to take a chunk out of you. You pull your weapon, fire a shot into the dog, it goes down.
Can the owner of the dog sue you for damages regardless of whether the dog dies or not?
