Curs are a member of the Hound group, and the Mountain Cur is one of several varieties of cur.  It can also be used as a water dog.  Mainly bred in Ohio, Kentucky, Virginia, and Tennessee, it has been registered with the United Kennel Club since 1998.  The Mountain Cur Breeder's Association was formed in 1957. The Treeing Cur is a breed of dog that originated in the mid-west and was first recognized by United Kennel Club on November 1, 1998, due to the efforts of Alex and Ray Kovac.  "Most Cur breeders were not well off and so they required a dog that could serve multiple purposes: hunter, guardian, and stock dog.  The result was the Treeing Cur, "which is the most varied in size and colors of the Cur breeds", according to United Kennel Club.They are primarily used to tree squirrels, raccoons, opossums, wild boars, bears, mountain lions and bobcats as well as to hunt big game. The Bloodhound is a large scent hound, originally bred for hunting deer, wild boar, and since the Middle Ages for tracking people.  Believed to be descended from hounds once kept at the Abbey of Saint-Hubert, Belgium, it is known to French speakers as the "Chien de Saint-Hubert". 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 The Catahoula bulldog is a crossbreed dog created by crossing the Catahoula Cur and the American Bulldog. Vulnerable Native Breeds are a group of dog breeds originating in the United Kingdom and Ireland, and identified by The Kennel Club (KC) as having annual registration numbers of 300 puppies or fewer.  The need for such a list was first identified in June 2003, with research conducted by the KC to identify the extent of the vulnerability and viability of each breed.  It was a joint project, with the KC working with the British and Irish Native Breeds Trust, later to be known simply as the Native Dog Breeds Trust.  The breeds on the list have been promoted at events such as Discover Dogs and Crufts, and by asking that owners of these breeds mate their dogs rather than having them spayed. The Basset Hound is a short-legged breed of dog of the hound family.  The Basset is a scent hound that was originally bred for the purpose of hunting hare.  Their sense of smell and ability to ground-scent is second only to that of the Bloodhound.  Basset Hounds are one of 6 recognised basset-type breeds in France.

The Catahoula Cur is an American dog breed named after Catahoula Parish, Louisiana, United States.  Also known as the Catahoula Leopard Dog, it became the state dog of Louisiana in 1979.  The breed is sometimes referred to as the "Catahoula Hound" or "Catahoula Leopard Hound" because of its spots, although it is not a true hound but a cur.  It is also called the "Catahoula Hog Dog", reflecting its traditional use in hunting wild boar. Wolf hunting with dogs is a method of wolf hunting which relies on the use of hunting dogs.
