Named for Catahoula Parish in Louisiana, this working dog was developed in the swamps and woods of the Gulf South to find and hold feral hogs and gather semi-wild cattle. Selection favored ability over looks, so size varies widely, roughly 50 to 95 pounds. The short coat often shows a merle "leopard" pattern, with eyes that can be blue, cracked or mismatched, though brindle and solid colors are common too.
Catahoulas tend to be intelligent, independent and loyal, with a protective streak and a strong work drive. They often stay wary of strangers, and some are selective with other dogs or small animals. Many shelter dogs labeled Catahoula are mixes, so each dog's own personality matters more than the label. Plan on daily vigorous exercise, firm but kind training and early socialization.
