The Norwich Terrier is a small, sturdy dog with an average weight of 11 to 12 pounds. Its body can be described as slightly longer than it is tall, standing 24 to 25 centimetres. It looks very similar to the Norfolk Terrier with the difference being that the Norwich Terrier has pricked ears. The Norwich Terrier has a slightly dome-shaped head, wedge-shaped muzzle and well-defined stop. The eyes are small, oval-shaped and dark in colour showing a bright and curious expression. Norwich Terriers have strong and muscular back legs and powerful front legs that are quite short. They carry their tails straight.
Norwich Terriers boast of a harsh and wiry topcoat that lies close to the body, whereas the undercoat is comprised of dense coat that is soft to touch. They also wear a ruff around the neck and hair on their heads, ears, eyebrows and whiskers. Accepted breed colours include wheaten, black, tan, grizzle and all shades of red.
Grooming a Norwich Terrier is a bit difficult since the wiry coat needs to be brushed several times daily to prevent matting. Often it is important to hire a professional groomer to perform hand stripping which is done at least 2 to 3 times a year. Norwich Terriers also shed throughout the year, most especially during autumn and spring, which means frequent grooming is required. Other than coat care, basic dog grooming is needed to keep them in top condition. This includes brushing the dog's teeth, cleaning its ears and trimming the nails.
