Question: Which dog breed is more rare, The Stabyhoun or The Norwich Terrier?
Context: The Stabyhoun or Stabij is one of the top five rarest dog breeds in the world.  It is from Friesland and in particular from the Frisian forest area, a region in the southeast and east of Friesland.  The breed has been mentioned in Dutch literature going back to the early 1800s, but has only extended its range from the 1960s outside of Friesland and not until the 2000s did the range officially extend beyond the Netherlands.  The name Stabij translates roughly as "stand by me" with the last part simply Frisian, meaning dog, which is pronounced "hoon".  The dog is considered a Dutch national treasure.  There are only a few thousand Stabyhouns in existence today worldwide. The Rat Terrier is an American dog breed with a background as a farm dog and hunting companion.  Traditionally more of a type than a breed, they share much ancestry with the small hunting dogs known as feists. Common throughout family farms in the 1920s and 1930s, they are now recognized by the United and American Kennel Clubs and are considered a rare breed.  Today's Rat Terrier is an intelligent and active small dog that is kept both for pest control and as a family pet. Rare breed (dog) is any breed of dog that is small in number and is used to refer to both old established breeds such as the Stabyhoun and Glen of Imaal Terrier or newer creations.  Since dogs have greater genetic variability than other domesticated animals the number of possible breeds is vast with new crosses constantly occurring, from these both selected and random crosses may come new breeds should offspring reliably breed true to type.  New breeds from the wild such as the Carolina Dog are quite rare compared to attempts at breed creation from man as found in the American Hairless Terrier which sought to exploit a mutation. The Telomian is a breed of dog native to Malaysia.  Though rare, it remains the only known Malaysian dog breed to live outside its homeland.  Malaysian are used to called this dog breed Anjing Kampung which means Village dog in Malay.  This dog breed is still remained rarest in the world. 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" (or folded ears).  Together, the Norfolk and Norwich Terriers are the smallest of the working terriers. The Airedale Terrier (often shortened to "Airedale"), also called Bingley Terrier and Waterside Terrier, is a dog breed of the terrier type that originated in the valley ("dale") of the River Aire, in the West Riding of Yorkshire, England.  It is traditionally called the "King of Terriers" because it is the largest of the terrier breeds.  The Airedale was bred from the Old English Black and Tan Terrier (now extinct), the Bull Terrier, the Otterhound and probably some other Terrier breeds, originally to serve as an all around working farm dog.  In Britain this breed has also been used as a war dog, guide dog and police dog.  In the United States, this breed has been used to hunt big game, upland birds, and water fowl, and serve in many other working capacities. The American Russell Terrier Club (formerly named the English Jack Russell Terrier Club), founded by JoAnn Stoll in 1995, was the first registry in the United States to maintain the Russell Terrier as a separate breed from the Parson Russell Terrier.  The American Jack Russell Terrier Club is affiliated with both the United Kennel Club and the American Kennel Club.  The purpose of the early founders was to establish a registry for the perpetuation and development of the Russell Terrier as a pure strain of working Jack Russell Terrier keeping their blood and type pure within the registry to works towards Kennel Club recognition as an official breed in the US.  On January 1, 2001, the United Kennel Club recognized the Russell Terrier as an official breed, designating only the stock from the American Russell Terrier Club as Foundation stock for the UKC Russell Terrier.  In 2004 the American Russell Terrier Club submitted an official request to include the American Russell Terrier Club stock into the AKC FSS Program to work towards becoming an official breed under the perimeters.  On December 8, 2004, the AKC officially accepted the Russell Terrier. The Norwich Terrier is a breed of dog originating in the United Kingdom, and was bred to hunt small vermin or rodents.  With a friendly personality, Norwich Terriers are today mostly a companion dog breed.  One of the smallest terriers, these dogs are generally healthy, but are relatively rare, due in part to their low litter size and the common need for caesarian sections.  Their drop-eared variety is the Norfolk Terrier. The Yorkshire Terrier is a small dog breed of terrier type, developed during the 19th century in Yorkshire, England, to catch rats in clothing mills.  The defining feature of the breed is its maximum size of 7 lb , although some may exceed this and grow up to 15 lb .  It is placed in the Toy Terrier section of the Terrier Group by the Fédération Cynologique Internationale and in the Toy Group or Companion Group by other kennel clubs, including the American Kennel Club.  A popular companion dog, the Yorkshire Terrier has also been part of the development of other breeds, such as the Australian Silky Terrier.  It has a grey, black, and tan coat, and the breed's nickname is "Yorkie". The Teddy Roosevelt Terrier is a small to medium-sized American hunting terrier.  Lower-set with shorter legs, more muscular, and heavier bone density than its cousin the American Rat Terrier.  There is much diversity in the history of the Teddy Roosevelt Terrier breed and it shares a common early history with the American Rat Terrier, Fox Paulistinha and Tenterfield Terrier.  It is said the Rat Terrier background stems from the terriers or other dogs that were brought over by early English and other working class immigrants.  Since the breed was a farm, hunting and utility dog there was little to no planned breeding other than breeding dogs with agreeable traits to each other in order to produce the desired work ethic in the dog.  It is assumed that the Feist (dog), Bull Terrier, Smooth Fox Terrier, Manchester Terrier, Whippet, Italian Greyhound, the now extinct English White Terrier, Turnspit dog and or Wry Legged Terrier all share in the Teddy Roosevelt Terrier's ancestry.  These early Ratting Terriers were then most likely bred to the Beagle or Beagle cross bred dogs (for increased scenting ability) and other dogs.  Maximizing the influences from these various breeds provides the modern Teddy Roosevelt Terrier with a keen sense of awareness and prey drive, an acute sense of smell and a very high intellect.  Although they tend to be aloof with strangers they are devoted companion dogs with a strong desire to please and be near their owners side at all times.
