The Norfolk Terrier is the smallest of the working Terriers. Prior to 1960, when it gained recognition as an independent breed, it was a variety of the Norwich Terrier, distinguished from the Norwich by its "drop", or folded ears.

Appearance
The Norfolk Terrier has a wire-haired coat which, according to the various national kennel club 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, the function for which it was bred.

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 cover more ground than their Norwich cousins. Norfolk have good side gait owed to their balanced angulation front and rear, not their perceived slightly longer length of back as is often cited.

The ideal height is 10 to 12 inches (25-30 cm) at the withers and weight is about 12 pounds (5 Kg).

Temperament
Norfolks are described as fearless, but should not be aggressive despite being capable of defending themselves if need be. They along with Norwich Terriers and Border Terriers, have the softest temperaments of the Terrier Group. Norfolks work in packs and must get along with other dogs. As companions in the home they love people and children and do make good pets. Their activity level is generally reflective of the pace of their environment. This breed should not be kept or live outside since they thrive on human contact. Generally Norfolks are not given to unnecessary barking or digging but, like any dog, will do either out of boredom when left alone for too long a period. They generally cohabitate well with other household pets when introduced as a puppy. Though, in the outdoors they are natural hunters with a strong prey drive for small vermin.

Norfolks are self confident and carry themselves with presence and importance, holding their heads and tails erect. A Norfolk that is shy, or carries its tail between its legs is untypical as is a dog that is hot tempered and aggressive with other dogs; these are not the standard. A Norfolk's typical breed temperament is happy, spirited and self confident. The greatest punishment to a Norfolk is his human companion ignoring him.

They were first called the Cantab Terrier when they became fashionable for students to keep in their rooms at Cambridge University in England. Later, they were called the Trumpington Terrier, after a street in the area where the breed was first developed. Then, just prior to World War I, a Norwich huntsman helped introduce the short-legged terriers to the USA, calling them the Jones Terrier.

In 1932, the Norwich was granted acceptance into the English Kennel Club and the first written standard was created. The American Kennel Club registered the first Norwich Terrier in 1936. In 1964, The Kennel Club reclassified the drop-ear variety as it its own breed, the Norfolk Terrier, and the prick-eared variety retained the name Norwich Terrier. The American Kennel Club and Canadian Kennel Club both recognized the division of the Norwich Terrier breed in 1979. The Norfolk Terrier was recognized by the United Kennel Club in 1979. After many generations, these two breeds have developed as two distinct breeds both in physical looks and in temperament. Of note, there is literature that suggests that the Norfolk and Norwich were always two distinct breeds and the original mistake was classifying them as one.

Working style
Norfolks were originally bred as barn dogs to rid the barn of vermin. Some literature suggest that they were also occasionally used on the hunt to bolt animals of equal size from their den. However their short legs do not make them an endurance dog to keep up with a horse. So there is some debate as to their use on a hunt. Norfolks are pack animals and hence expected to get along with other dogs while working or in the home. As a pack dog they take turns working their prey. They are fearless and their courage is incredible. Today of course they are household companions and must have an agreeable disposition for living with people.

Health
The life expectantcy of a Norfolk Terrier is 12 to 16 years, with some growing as old as 19 years. They are generally considered as a healthy breed but there are incidences of health issues that Responsible Breeders consider worthy to do preventative testing. Norfolks have incidences of mitral valve disease, hip dysplasia, luxating patellas, and incorrect bites (where the teeth do not align with the breed standard, i.e. overshot or undershot).

Norfolks generally have small litters averaging two puppies. Responsible Breeders only breed healthy dogs that have been genetically tested for known ailments of the breed, are of good temperament, champion pedigree lineage and best reflect the written national kennel club standard. The demand for Norfolk is far greater than the supply. The environment in which they are raised directly impacts the temperament of the puppy for its lifetime. Norfolks do not thrive in kennel environments.

Grooming
These breeds have a double coat - a harsh, wiry topcoat and a soft, warm undercoat. Ideally the coat is combed daily with a steel "greyhound " comb, but all that is really necessary for grooming a companion dog is a good combing once a week to remove the loose, dead hairs and prevent matting. As a minimum, the coat should be hand stripped once in the Fall and once in the Spring. Clipping or cutting ruins the coat's colours and harsh texture. You can wash this coat with a dog shampoo any time it is desirable.
