The Catahoula Leopard Dog comes from Catahoula Parish in Louisiana, where it was developed to find and hold feral hogs and to gather semi-wild cattle. Ability mattered more than looks, so size and build vary a lot. Many have a merle or leopard coat and glass-blue or mismatched eyes, but brindle and solid colors are common too.
Catahoulas tend to be intelligent, independent and fiercely loyal, with a protective streak and a strong work drive. They often bond closely with family and stay wary of strangers. Plenty of shelter dogs labeled Catahoula are mixes, so each dog's own personality and energy level tell you more than the label does. Daily exercise, firm but kind training and early socialization go a long way.
