When that moose attacked the sled dogs, I read quite a bit about the story. And the details about why the woman on the dogsled had a .380 are useful to anyone who tries to be prepared.
The incident with the moose happened pretty close to a populated area, and there was an attempted assault or sexual assault in the area shortly before the moose incident. So the dogsled driver was carrying a small pistol as a response to the most recent threat. Apparently, moose were not a big concern so close to human population.
However, in hindsight, people who knew the area were aware that moose were a potential threat in the area. And people in Alaska are aware that moose can be very ornery, and that moose attacks are more common than bear attacks. That may be because there are a lot more moose than bears in Alaska, but it is still the case that moose are a known threat.
So she was carrying a .380 as a response to the most recent threat, instead of thinking about the overall picture of her operating environment.
