Southern farmers and hunters developed the Black Mouth Cur as an all-purpose working dog that could tree squirrels and raccoons, bay hogs, move cattle and watch over the homestead. Most have a short yellow, red, fawn or brindle coat and the dark muzzle that gives the breed its name. The breed is often linked with the dog in the novel Old Yeller.
These are muscular, athletic dogs with plenty of stamina, and many are devoted to their families while staying wary of strangers. They tend to be sensitive to harsh handling and do best with calm, consistent, reward-based training. Cur-type dogs are common in Southern shelters, and they can thrive with active adopters who offer daily exercise, a job to do and secure fencing.
