The Catahoula Leopard Dog is an American dog breed named after Catahoula Parish, Louisiana. It became the state dog of Louisiana in 1979. It has traditionally been used in hunting feral boars. Native Americans tended to use the dog for hunting large game. European settlers used the dog for hunting and herding livestock. The first white settlers in Louisiana are believed to have used the dog to hunt feral pigs in the swamps of Louisiana. Herding instincts and trainability can be measured at noncompetitive herding tests. Catahoulas exhibiting basic herding instincts can be trained to compete in cow/hog dog trials. Toy Fox Terrier.
