The Catahoula Leopard Dog is an American dog breed named after Catahoula Parish, Louisiana. Both registries have assigned the breed a herding group designation. 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. 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.
