Not an American are you? Americans don't need permits to carry firearms on public range, either in forests or non-forested land. Yes, carrying a firearm is "allowed" on BLM land. I believe DesertRhino was saying if the dog attacked him he would shoot it. A simple case of self defense.
Thank you. And to be clear,, i wouldn’t want to hurt one of those fine dogs. It would be a last resort. But bites to my own corpus delecti must ALWAYS be prevented.
