The American Foxhound is a breed of dog that is a cousin of the English Foxhound.
 They are scent hounds, bred to hunt foxes by scent.
The Stephens Cur (a.k.a. Stephens' Stock Cur), is a scent hound that belongs to the Cur dog breed.
 They were originally bred by the Stephens family in southeastern Kentucky.
 The dogs known as "Little black dog" were bred by generations of that family for over a century.
 In 1970, they were recognized as separate and distinct breed of Cur.
 The dog is mostly black with white markings, but more than a third white is not permissible.
 It is good for hunting raccoon and squirrel, but can also be used to bay wild boar.
 They are registered with the United Kennel Club
Fox hunting is an activity involving the tracking, chase and, if caught, the killing of a fox, traditionally a red fox, by trained foxhounds or other scent hounds, and a group of unarmed followers led by a "master of foxhounds" ("master of hounds"), who follow the hounds on foot or on horseback.
The English Foxhound is one of the four foxhound breeds of dog.
 It is a cousin of the American Foxhound.
 They are scent hounds, bred to hunt foxes by scent.
Sighthounds, also called "gazehounds", primarily hunt by sight and speed, rather than by scent and endurance as scent hounds do.
Scent hounds (or scenthounds) are a type of hound that primarily hunts by scent rather than sight.
 These breeds are hunting dogs and are generally regarded as having some of the most sensitive noses among canines.
The Billy is a large scenthound originating from central western France.
The Porcelaine ] is a breed of dog originating from France.
 It is believed to be the oldest of the French scent hounds. Its alternate name is the Chien de Franche-Comté, named after a French region bordering Switzerland.
 This caused some debate over the dog's origin, but it has been decided that it is a French dog.
Paper Chase (also known as Hare and Hounds or Chalk Chase) is a racing game played outdoors (best played within a wood or even a shrubbery maze) with any number of players.
 At the start of the game, one person is designated the 'hare' and everyone else in the group are the 'hounds'.
 The 'hare' starts off ahead of everyone else leaving behind themselves a trail of paper shreds (or chalk marks in an urban environment) which represents the scent of the hare.
 Just as scent is carried on the wind, so too are the bits of paper, sometimes making for a difficult game.
 After some designated time, the hounds must chase after the hare and attempt to catch them before they reach the ending point of the race.
 It is generally done over a long distance, but shorter courses can be set.
 If the hare makes it to the finish line, they get to choose the next hare, or to be the hare themselves.
 Similarly, the person who catches the hare gets to choose the next hare.
Mink hunting is a country sport involving the hunting of American mink with scent hounds along the waterways which make up their habitat, in a manner similar to fox hunting.
 Mink hunting took place in the countryside in the UK and Ireland, but since 2005 traditional mink hunting has been banned in England and Wales.
