A few years ago, just two days before Christmas in Fort Nelson, British Columbia, a dog named Shadow saw something that his human family didn’t: two hungry wolves. The family headed out to go tobogganing in the late afternoon, and the three young children were towed out to a hill by their dad in an all-terrain vehicle while mom waited for them at the top. The mom started shrieking when she suddenly saw Shadow spring into action as the wolves moved toward the children. Shadow, a Rottweiler mix, intercepted the lead wolf, which in turn hit Shadow in the side and grabbed his shoulder. The dad began swatting at the wolves with a shovel but they didn’t budge. Shadow kept growling at them and ultimately the dad chased them off into the woods. Shadow survived with some bumps and bruises.
