Come on. Worried about being attacked by wolves, even in Idaho where they are doing quite well? 825 wolves in an 83,642 square mile state?
Pack a camera instead and get a real shot of a lifetime.
When I lived in Alaska (Healy, to be exact, then out in the Chugach range area, south) and locals there will tell you, wolves won't bother a human, a human with dogs, or any such. Too smart. Not interested--you're not their prey. Shot at by hunters/poachers. Etc etc. Bears are another story. You damn well do carry a gun for the bears, though--I had a S&W .44 Magnum. But people up there don't carry for wolves--bears are what they are worried about.
Maybe Idaho wolves are different. I doubt it.
You'd be lucky as hell to ever see one. Maybe, if you're EXTREMELY lucky, on the ridge across the valley.
Waste of energy to carry a gun, worried about wolves fer gosh sakes.
I grew up in La Grande, Oregon, so this interested me:

If someone was recently kidnapped and murdered in your hiking area, I'd carry a piece. Worried about wolves, never. And I own a Colt M4, Steyr 9mm, Walther .22, first year Ruger 10-22, etc etc. I'm no anti-gun nut. YMMV!
