Fox Terriers are two different breeds of the terrier dog type: the Smooth Fox Terrier and the Wire Fox Terrier.
 Both of these breeds originated in the 19th century from a handful of dogs who are descended from earlier varieties of British terriers, and are related to other modern white terrier breeds.
 In addition, a number of breeds have diverged from these two main types of fox terrier and have been recognised separately, including the Jack Russell Terrier, Miniature Fox Terrier and Rat Terrier.
 The Wire and Smooth Fox Terriers share similar characteristics, the main differences being in the coat and markings.
 They have been successful in conformation shows, more prominently in America than their homeland.
Rya, also known as Ryafår or Swedish Carpet Wool Sheep, is a breed of sheep that is native to Sweden.
 The breed originated from the Swedish and Norwegian landrace breeds.
 This double-coated breed of Swedish Landrace origin also contains some Norwegian Spælsau heritage.
 The purpose of the sheep was to use the long, wavy, and shiny wool to produce rya-wool, which is often used to make carpets.
 In the early twentieth century, few long wool sheep remained in the province of Dalarna, leading to the restoration of the rya sheep breed.
 In 2000, there was a stable population of about two thousand rya sheep.
 They can be found in northern and central Sweden.
 Most of herds are located in Dalarna.
 They are usually kept in small flocks.
The Russian Toy (also known as the Russian Toy Terrier, and in Russia as the Russkiy Toy, Toychik,Russian: Русский той, Тойчик ) is a very small breed of dog originally bred in Russia from the English Toy Terrier which is known today as the Manchester Terrier.
 There are two types of coats in the breed: smooth coat and long coat.
 The smooth-coated variety was previously known as the Russian Toy Terrier and long-coated as the Moscow Long Haired Toy Terrier.
 Both were brought together under the same Russian Toy Terrier name in 1988 and the "Terrier" was dropped from the name when the breed was added in 2006 to the official list of breeds registered with the Fédération Cynologique Internationale and has been registered in the Foundation Stock Service of the American Kennel Club since 2008, allowed to compete in AKC companion events since 2010.
 The first official breed standard of the two varieties was written in 1966 in Russia.
The Belgian Landrace, also known as the Improved Belgian, Belgian Improved Landrace, and the Belgian Lop-eared, is a breed of domestic pig from northern Belgium.
 It was created from importing English breeds and improving them until they were "graded up" to the German Improved Landrace from 1930 to 1945 and then breeding them with the Dutch Landrace in 1945.
 Other breeds were also incorporated into the bloodline to strengthen it, such as with ones from Luxembourg in 1955, Germany in 1971, and the Czech Republic in 1974.
 Used in many different countries, the Belgian Landrace is also one of the "four major commercial breeds" in France.
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.
The Cantabrian Water Dog (Spanish: perro de agua cantábrico ) is a landrace breed of dog developed in the coast of Cantabria, northern Spain, as an assistant to fishermen.
 The breed was classified and recognized by the Breeds Committee of the Spanish Ministry of Environment on 22 March 2011.
The Toy Manchester Terrier is a breed of dog, categorized as a terrier.
 The breed was bred down in size in North America from the Manchester Terrier, and is placed in the Toy Group by the American Kennel Club and the Canadian Kennel Club (the Manchester Terrier is placed in the Terrier Group.)
 Neither the Fédération Cynologique Internationale nor The Kennel Club recognize a Toy variety of the Manchester Terrier.
The term Landrace pig or Landrace swine refers to any of a group of standardized breeds of domestic pig, and in this context the word "Landrace" is typically capitalized.
 The original breed by this name was the Danish Landrace pig, from which the others were derived through development and crossbreeding.
 The breed was so-named because the foundation stock of the Danish Landrace were specimens from the local, free-breeding, non-pedigreed stock of swine, i.e. the regional landrace native to Denmark.
 The modern breeds are not themselves landraces, since they are formal breeds maintained through selective breeding rather than natural selection.
 The establishment and spread of the Danish breed gave the word "landrace" to the English language (it had already existed in Danish, German, Dutch and some other Germanic languages).
 Sources from the mid-20th century often mean the Danish Landrace swine in particular when referring to "Landrace" pigs, as most of the others had not been developed yet.
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 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".
