American Leopard Hounds are one of the oldest of the tree dog breeds in the Americas. The exact origins of the American Leopard are unknown.
The early settlers of America were a farming people and would often keep hundreds of cows, pigs and chickens on their settlements. It was quite common for the settlers to build a wooden fence around their homes and to let their animals roam freely around the perimeter of this fence. It is believed that the Leopard Hound was charged with rounding up this livestock and herding back any that escaped.
By the early 18th century, American Leopard Hounds had become established in eastern North Carolina. From there, it made its way west into Tennessee and Kentucky and, later, south into Texas and Oklahoma.
During the early 20th century, the breed began to decline and was allowed to cross with other breeds, so much so that by the 1950s, few purebred examples could be found.
Realizing this, three individuals, J. Richard McDuffie, Leroy E. Smith, and A.W. Carter, began to independently search for any examples of the breed. Meeting in 1960, these three men established the American Leopard Cur Breeders Association (ALCBA) to establish and promote the breed.
