i wouldnt say lucky,,,its down to circumstances! how often is the dog doing it? if your bull/whip is actually catching foxes its only doing it in and around cover! and not in the open field and it would prob need a hand to finnish matters,,a good fox will out preforme a bull/whip in the open field,, good foxdogs out preforme foxes in the open field not just round obstacles that slow em down! or like you say you may just have a one off........!! any preban pics of this dog.why would you think they wouldnt catch on open fields
because iv never seen one do it! and iv seen a couple day/night,
