Grizzly Bears vs Wolves or Mountain Lion

Grizzlies may have encounters with cougars, wolverines, wolves, black bears or coyotes, but these smaller animals will give way quickly, abandoning kills, dens and resting spots unless, in the case of a wolf or coyote pack, they have serious numbers on the grizzly, and even then, the risk is too great. A grizzly can kill a wolf or mountain lion with one swipe of its paw.
