break gruff ankle

I don't know much about goats, but I do know a little about horses, having taken care of my second mentor Ebenezar McCoy's riding horses on his little farm in Missouri. Their feet are awfully vulnerable, especially considering how much weight they're putting on such a relatively small area. Any one of a hundred little things can go wrong. One of them is the possibility that some of the surprisingly frail little bones just above the back of the hoof could be fractured or broken. A pastern or fetlock injury like that can lame a horse for weeks, even permanently.
So as I passed the staggered gruff, I swung my heavy staff like a baseball bat, aiming at the back of one of his hooves. I felt the impact in my hands and heard a sharp crack. The gruff let out a high-pitched and utterly bestial scream of surprise and pain, and tumbled to the snow. I all but flew on by, lengthening my stride, crossing the street and heading for the nearest corner, before his buddies could get a clear shot at me.
When you drive game, you'd damn well better be sure that the one you're driving the prey toward is ready and able to handle it.
