The Black Mouth Cur is a medium-to-large American working dog of cur type, developed in the Southern United States as an all-purpose farm, hunting, and homestead dog. Known in different lines as the Southern Cur, Southern Black Mouth Cur, or Yellow Black Mouth Cur, the breed takes its name from the dark mask and pigmented lips and gums that most dogs carry. This is one of America's true working breeds: a fast, agile, weather-hardened dog bred for results rather than looks, and it remains a favorite of hunters, ranchers, and active rural families across the South.
The breed has one of the great claims to fame in American dog culture: the title character of Fred Gipson's classic novel Old Yeller is widely claimed to have been a Black Mouth Cur. The United Kennel Club recognized the breed in 1998, though it is not recognized by the American Kennel Club. For experienced, active owners who can give this dog a genuine job, the Black Mouth Cur is a devoted, courageous, and remarkably healthy companion.
