Named for Catahoula Parish in Louisiana, this athletic working dog was developed in the swamps and woods of the Gulf South to find and hold feral hogs and gather semi-wild cattle. Because ability mattered more than looks, size and build vary a lot. Many have a merle "leopard" coat, sometimes with glass-blue or mismatched eyes, though brindle and solid colors are common too.
Catahoulas tend to be intelligent, independent and intensely loyal, with a protective streak. Many are wary of strangers, and some are selective with other dogs or small animals. Daily vigorous exercise, early socialization and firm but kind training all matter. Many dogs labeled Catahoula are mixes, so the dog in front of you matters more than the label.
