I also had my first dog bring a bear back to me, but nowhere as scary as your experience. She was a very alpha female lab who wasn't afraid of anything. We were walking down an old road one day when I spied a bear feeding on clover about a hundred yards ahead. Meanwhile my dog was at my side minding her own business (for a change) so I looked down and said "You be good." What I should have done was grabbed her collar because those 3 words got her looking around to see what she was missing; she then tore off and ran PAST the bear. She sniffed the ground for a few seconds then ran back past the bear, returning to my side while the bear ran off. "At least it didn't have cubs" I thought.I also learned after the fact that a dog WILL bring the bear that’s chasing it back to you, it’s just a matter of when.
Wrong!!! The next thing I knew the bear was standing with her front paws on the shoulder of the road, 15 feet away. I started clapping my tree calipers together making as much noise as I could. She may get me but I'm going down hard. We stared at each other for a few seconds, then she took off into the woods.
I yelled at my dog "GTF away from me!!!!" I DON'T WANT YOU anymore!!! It was a couple of hours before I even acknowledged her, I was so mad.
We only have black bears here. They are just miniature versions of a real bear.
