The Norfolk Terrier is a British breed of dog. Prior to gaining recognition as an independent breed in 1964, it was a variety of the Norwich Terrier, distinguished from the "prick eared" Norwich by its "drop ears". Together, the Norfolk and Norwich Terriers are the smallest of the working terriers.
The Norfolk Terrier has a wire-haired coat which, according to the various national kennel clubs' breed standards, can be "all shades of red, wheaten, black and tan, or grizzle." They are the smallest of the working terriers. They are active and compact, free moving, with good substance and bone. Good substance means good spring of rib and bone that matches the body such that the dog can be a very agile ratter or earth-dog.
Norfolk terriers are moderately proportioned dogs. A too heavy dog would not be agile. A too refined dog would make it a toy breed. Norfolks generally have more reach and drive and a stronger rear angulation, hence covers more ground than their Norwich cousins. Norfolk has good side gait owed to their balanced angulation front and rear and their slightly longer length of back.
