The AKC breed standard states that the correct coat color is either a black saddle, with a tan head, ears and legs; or a dark grizzle saddle (black mixed with gray and white). Grizzle that is a mix of red hair in the black, often on the area of back before the tail are often the best and harshest coats. Terriers were often the sporting dog of choice for the common man. Early sporting terriers needed to be big enough to tackle the quarry, but not so big as to prevent them from maneuvering through the quarry's underground lair. As a result, these terriers had to have a very high degree of courage and pluck to face the foe in a tight, dark underground den without the help of human handlers.
