Moose are dangerous, at least that's what I read in the literature. Fortunately, I've never run into one. Here's a summary of important points related to being around them.
1. Moose can run at 30-35 mph.
2. Moose react to dogs as if they were wolves, their natural enemies. It's best not to camp with dogs in moose country.
3. If you are charged by a moose, run, and try to climb a tree before it reaches you. If the moose catches you , it will knock you to the ground. It may run off or it might stomp and kick with all four feet. In this case curl up in a ball and try to protect your head. Lie still.
4. Cow moose are extremely protective of their calves, and will charge any threats.
5. In Alaska, moose injure more people than grizzlies and black bear combined.
6. Fed moose quickly habituate to people, then approach stangers expecting a snack and get angry when they aren't fed.
7. Your first sign that a moose is aware of your presence is often that it simply stops what it's doing and looks at you. That is your warning that something is wrong.
