The breed originally had two varieties, one with drop ears and one with prick ears, which were interbred and shown together. The Norwich Terrier was recognized by the United Kennel Club in 1979. It has a natural, weatherproof coat and is sturdy, with good bone and substance. Honorable scars from fair wear and tear are acceptable and never to be penalized in the show ring.
All faults are to be penalized in relation to the degree of deviation from the ideal.
It has sensitive prick ears and a slightly foxy expression. Spirited and stocky, they are one of the smallest working Terriers. The broad, slightly rounded skull has good width between the ears. Lip pigment is black. The small, dark, oval-shaped eyes are placed well apart.
