The Catahoula Leopard Dog comes from Louisiana's Catahoula Parish, where it was developed to find and hold feral hogs and gather semi-wild cattle. Ability mattered more than looks, so size and build vary widely, from about 50 to 95 pounds. The coat is short and smooth, often merle with glass-blue or mismatched eyes, though brindle and solid dogs are common.
Catahoulas tend to be smart, independent and loyal, with a protective streak and some wariness of strangers. Some are choosy about other dogs or chase small animals. They need hard daily exercise, firm but kind training and early socialization. Many shelter dogs labeled Catahoula are mixes, so a dog's own personality tells you more than the label, which is worth remembering when you meet one in San Francisco.
