When we hike we carry a marine airhorn... its great for stopping moose and dogs... not sure out brownies though. The times I've used it, it causes dogs to about do a back flip... moose immediately turn and run. Before you call me a moron, we also hike with a firearm. Only been in AK 3 years, but other states have moose and bears... just incase you've never been out of AK.
