A hunting dog, particularly a hound that was traditionally used to hunt deer or other game.
From Middle English 'buck' (male deer) combined with 'hound' (hunting dog). The term emerged in medieval English sporting vocabulary to describe dogs specifically bred and trained for pursuing male deer during hunts.
Medieval nobles were so obsessed with deer hunting that they created specialized dogs just for bucks—different from other hunting hounds! This shows how precision breeding goes back centuries before modern dog breeds were officially registered.
