Bears, no . . . but calves, ducks & geese . . yes. Many years ago, I got my first horse because of herding. She was a race bred QH that had been retired from racing because of an injury before she was 3 yrs. The owner had her in a pasture with calves that were supposed to be fattening up for slaughter. She kept them in all four corners of the pasture and then would round them up and redistribute them to different parts of the pasture. She also would not let them eat. After I got her, she turned her herding on the local ducks and geese. Good thing they could fly, otherwise they wouldn't have gotten to eat either.
Her herding instincts were very strong. This race mare just had way too much cow pony in her.
