 The purpose of this is to teach inexperienced hounds to hunt and kill and to cull weaker young foxes; which are full size by autumn, although not yet sexually mature.Another goal of cub hunting is to teach the young foxhounds to restrict their hunting to foxes.The activity sometimes incorporates the practice of 'holding up', which consists of hunt supporters surrounding a covert, with riders and foot followers to drive back foxes attempting to escape, and then "drawing" the covert with the puppies and some more experienced hounds, allowing them to find and catch foxes within the surrounded wood.
