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. Its exact roots in Tennessee or Mississippi are debated, and it's often linked with the dog in the novel Old Yeller. Most have a short yellow, red, fawn or brindle coat and the dark muzzle that gives the breed its name.
These are muscular, athletic dogs with real stamina, usually 40 to 95 pounds. Many are deeply loyal and protective with family, sensitive to harsh handling and wary of strangers. They tend to thrive with daily exercise, a job to do, secure fencing and calm, consistent training. Each dog is different, so energy and prey drive vary from one cur to the next.
