The Catahoula Leopard Dog is an American dog breed named after Catahoula Parish, Louisiana. It became the state dog of Louisiana in 1979. It is recognized by the United Kennel Club under the name Louisiana Catahoula Leopard Dog, while the American Kennel Club Foundation Stock Service calls it Catahoula Leopard Dog. Both registries have assigned the breed a herding designation, although it has traditionally been used in hunting feral boars.
