Context paragraphs:
Alaunt: The Alaunt is an extinct breed of dog, with the original breed having existed in central Asia and Europe from ancient times through the 17th century.  The Alaunt breed had three distinct phenotypes: Alaunt Veantre, Alaunt Boucherie and the Alaunt Gentile.  They all were large, short coated dogs of varying head-types.  The former two resembled the molosser type dogs much like the present-day Dogo Argentino or like the Caucasian Shepherd Dog except with short hair and a mesocephalic head which made them excellent large-game hunters.  The Alaunt was originally bred by the Alani tribes, the nomads of Indo-European Sarmatian ancestry who spoke an Iranian language.  The Alans were known as superb warriors, herdsmen, and breeders of horses and dogs.  The Alans bred their dogs for work and developed different strains within the breed for specific duties.  The breed was further developed in Spain, France, Germany, England, and in Italy.

Jafrak Philippe Olivier: Ch.  Jafrak Philippe Olivier, also known as Philip, was a male Giant Schnauzer who won the title of Best In Show at Crufts in 2008.  He had previously won the Working Group in 2004 and 2005.

Perro de Presa Canario: The Perro de Presa Canario, A.K.A. the Canary Mastiff, is a large Molosser-type dog breed originally bred for working livestock.  The name of the breed is Spanish, means "Canarian catch dog", and is often shortened to "Presa Canario" or simply "Presa".  The breed is sometimes also called Dogo Canario, meaning "Canarian Molosser".  It is the animal symbol of the island of Gran Canaria.

Nonius horse: The Nonius (Hungarian: "Nóniusz" ) is a Hungarian horse breed named after its Anglo-Norman foundation sire.  Generally dark in color, it is a muscular and heavy-boned breed, similar in type to other light draft and driving horses.  The breed was developed at the Imperial Stud at Mezőhegyes, Hungary by careful linebreeding.  Originally bred to serve as a light draft and utility horse for Hungary's military, the breed became a useful agricultural horse during the 20th century.  The depredations of World War II significantly reduced the Nonius' population, and in the decades after the war, a downturn in the usage of horses in Hungary sent many members of the breed to slaughter.  Today the breed is bred by preservationists and is used in agriculture, leisure riding, and competitive driving sports.  The largest numbers of Nonius horses are still found at Mezőhegyes, with representatives in other eastern European nations as well.

Shargleam Blackcap: Ch.  Shargleam Blackcap, (born 26 June 1977), also known as Brett is a Flat-Coated Retriever show dog bred and handled by Mrs Pat Chapman who won Best in Show at Crufts in 1980.  He is one of the ancestors of 2011 Crufts Best in Show Sh Ch.  Vbos The Kentuckian.

Kerry Blue Terrier: The Kerry Blue Terrier (also known as the Irish Blue Terrier) () is a breed of dog.  Originally bred to control "vermin" including rats, rabbits, badgers, foxes, otters and hares, over time the Kerry became a general working dog used for a variety of jobs including herding cattle and sheep, and as a guard dog.  Today the Kerry has spread around the world as a companion and working dog.  Despite a Kerry Blue winning Crufts (the most important UK dog show) in 2000, it remains an "unfashionable" breed, and is distinctly uncommon; however, it not as threatened as some of the other terrier breeds such as Skye Terrier, Sealyham Terrier, and Dandie Dinmont Terrier.

Blanc de Hotot: The Blanc de Hotot is a medium-sized rabbit breed originally developed in France.  It is a compact, thickset white rabbit with spectacle-like black rings around each dark eye.  First bred in Hotot-en-Auge, Normandy, France in the early 1900s, the breed spread throughout Europe and into North America by the 1920s.  Initially unpopular in the United States, it died out there, and suffered population decline in World War II-era Europe.  It began to spread again in the 1960s and 1970s, and was re-imported to the US in 1978.  Today it is recognized by the British Rabbit Council and the American Rabbit Breeders Association, but is considered globally endangered, with a listing of "threatened" status by the American Livestock Breeds Conservancy.

Giant Schnauzer: The Giant Schnauzer is a working breed of dog developed in the 17th century in Germany.  It is the largest of the three breeds of Schnauzerthe other two breeds being the Standard Schnauzer and the Miniature Schnauzer.  Numerous breeds were used in its development, including the black Great Dane, the Bouvier des Flandres, and the German Pinscher.  Originally bred to assist on farms by driving livestock to market and guarding the farmer's property, the breed eventually moved into the city, where it worked guarding breweries, butchers' shops, stockyards and factories.  It was unknown outside of Bavaria until it became popular as a military dog during World War I and World War II.

List of Best in Show winners of Crufts: The title Best in Show is awarded annually to the dog chosen as winner of the Crufts dog show, according to conformation show rules.  This title was first awarded in 1928, the initial winner being Primley Sceptre, a fawn Greyhound.  Previously, Crufts had used the title "Best Champion", sponsored by the "Illustrated Kennel News", which was awarded from 1905 to 1914.  The first winner of Best Champion was Ch.  The Sable Mite, a Pomeranian.  According to "Crufts: The Official History" the first winner of that award was the first dog to be considered the "best" at a Crufts show, although it only lists winners between 1906 and 1912.

Pit bull: Pit bull is the common name for a type of dog.  Formal breeds often considered in North America to be of the pit bull type include the American Pit Bull Terrier, American Staffordshire Terrier, American Bully, and Staffordshire Bull Terrier.  The American Bulldog is also sometimes included.  Many of these breeds were originally developed as fighting dogs from cross breeding bull-baiting dogs (used to hold the faces and heads of larger animals such as bulls) and terriers.  After the use of dogs in blood sports was banned, such dogs were used as catch dogs in the United States for semi-wild cattle and hogs, to hunt and drive livestock, and as family companions.  Despite dog fighting now being illegal in the United States, it still exists as an underground activity, and pit bulls are a common breed of choice.
