Culling
There is a point when it's time to get out of the way. Standing down a sheep may work, but give her an edge or agitation and then you are just in her path to freedom and jumping over or into you becomes the most viable path. I probably should have reiterated this to Kate a little more as we were chasing down an errant ewe with a halter still around her face, the lead yanked out of my hands as we wrestled her from a pen to her future groupie group with the ram.
