Revisiting this thread since it was revived.
This seems to be the pattern. Here in Idaho, one of our more famous (or notorious) individuals got into some legal trouble after shooting a wolf that was after his dog. The dog was, of course, running for its life - back to its master. Claim was personal defense, and maybe it was legit. But it was probably the presence of the dog that triggered the event.
A good dog will keep camp raiding bears away, but who of us have had that problem away from the popular camping places? I love dogs more than most people (read that either way) but I prefer to leave mine home when heading for the wilderness.
Idaho has had a healthy population of wolves for over 25 years now and as others have said, they don't worry me. I have seen exactly one up close and acting naturally, and that is one of my most precious memories. I have heard many. I was surrounded by them singing for most of one night, but they didn't enter my camp as far as I could tell - and I didn't have a fire going. I see their spoor often. I'm more cautious about angry moose than any other animal. My son, who encounters moose while fishing far more often and closer than he likes does carry a large handgun just in case. He has wolves and grizzlies around him too, but it's the moose that concern him most.
Back to dogs....
If I find a dog that will help portage my gear, set up my tent and filet my fish, maybe I'll let it come along. Otherwise, I'm fine without one.
