 The hunts claim to provide and maintain a good habitat for foxes and other game, and, in the US, have fostered conservation legislation and put land into conservation easements.Anti-hunting campaigners cite the widespread existence of artificial earths and the historic practice by hunts of introducing foxes, as indicating that hunts do not believe foxes to be pests.It is also argued that hunting with dogs has the advantage of weeding out old, sick, and weak animals because the strongest and healthiest foxes are those most likely to escape.
