Yep, we had a bad ass farm dog. That dog was a woodchuck hunter among the best. He would sneak up on a woodchuck and the woodchuck would sit up on his hind legs when it spotted the dog. Our dog would see that and then start running circles around the woodchuck. The woodchuck would pivot around on his hind legs at the speed the dog was circling him. The woodchuck would get all dizzy and fall over and our dog would go in for the kill grabbing the woodchuck by the neck and breaking it.
Woodchucks are bad if they took up residence in the cow pasture. Woodchucks dig and entry hole on an angle and an exit hole vertically. A cow could step into the hole and break a leg and it would be all over for the cow. Best to see the woodchuck meet their demise rather than a valuable cow.
