The Black Mouth 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. Scars should neither be penalized nor regarded as proof of a dog’s working abilities.

The Black Mouth Cur is a fast, hard hunter that finds game using its eyes, ears and nose. Silent trailers are preferred, although slightly semi-open on a very hot track is allowed. Never open like a hound. A loud, deep chop on bay or tree, ringing cry or slight yodel allowed. Never full-blown bawl mouthed. The Blackmouth Cur combines tenacity and courage with a strong desire to work. They are very loyal and protective of their owner and family.
