The Bedlington terrier is unmistakable for its striking resemblance to a lamb.
Its most distinguishing features are its pear-shaped, tufted head, curly coat, arched back, lithe stature, and graceful, springy gait. The head is narrow, deep and rounded, the jaw longer than the skull. The slender muzzle has a distinctive Roman arch. The triangular ears, which hang flat against the cheeks, have whimsical, 'cotton-puff' tips. The long, tapering neck stands high atop a muscular and flexible body. The chest is deep, the tail set low and tapering, and the front legs straight with hare-like feet. Females measure 15 1/2 inches at the withers, and males measure 16 1/2 (males) inches at the withers, and the dog weighs 17 to 23 pounds (eight to 10 kilograms).
The pliant, curly coat is a unique mixture of hard and soft hair that conceals the bone structure on the muzzle and front legs, where it thickens. The coat colors are blue, sandy, liver, tan, blue and tan, and sandy and tan. Today, the blue color is fashionable and more prevalent than the others.
