"What could have been a tense encounter recently with two wolves during a hike in North Idaho turned out to be a pleasant experience for me and my Brittany, Ranger, for several reasons:
The dog was close by when I ran into wolves along the trail.
Ranger came to my call immediately when I spotted a wolf off the trail.
I had a leash to keep Ranger close as the wolves approached to investigate.
I had bear spray handy for peace of mind even though I didn't need to use it to defend my dog."
