Jeremy and Angela were camped on public land, but the dog was theirs. And, an argument can be made that as citizens, they were on “their” land - the state is the steward of the land, which is different from private citizen ownership of land.
Well, used to be, anyway.
Hunters in Idaho often grab a mountain lion tag just to cover the off chance that a big kitty shows up uninvited when hunting something entirely different. I just grabbed a copy of the big game hunt information from Idaho Fish & Game. I've missed all the deer seasons. There is a Spring black bear season.
