In any event, these dogs were widely used by early American settlers as all-round working dogs. As Americans moved west, the Blackmouth Curs moved with them, serving as a hunting dog and family guardian. The Blackmouth Cur was recognized by U.K.C. on November 1, 1998. The Blackmouth Cur is a powerful, agile tree dog of medium size. The body is square or just slightly longer than tall.
Legs are long enough to allow the dog to move quickly and with agility in rough terrain.
The head is broad with a moderate stop and a moderately broad muzzle. Ears are set high and drop. The tail is straight, set low, and may be any length. The coat is short and close fitting. The Blackmouth Cur should be evaluated as a working dog, and exaggerations or faults should be penalized in proportion to how much they interfere with the dog's ability to work.
