Y'all are lucky. I have yet to see how a hog stops. Hada guy tell me that his dog grabbed nut to stop hogs. Asked him how many times he saw a running hog. Never. Just that his dog was always on the nuts when he got to the catch.
Hell , my old dog must be a super star , she hits the leg after the bulldog gets there.

Run the hog until he can't anymore or catch the hog drum the start. Only two solutions I see.
