Context paragraphs:
Cockapoo: A Cockapoo (also known as a spoodle) is a mixed-breed dog that is the cross between either Cocker Spaniel breeds (American Cocker Spaniel or English Cocker Spaniel) and a poodle (in most cases a miniature poodle or toy poodle).

American Russell Terrier Club: 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.

Russell Terrier: The Russell Terrier is a predominantly white working terrier with an instinct to hunt prey underground.  The breed was derived from the Reverend John Russell's working terrier strains that were used in the 19th century for fox hunting.  The Reverend's fox working strains were much smaller than the Show Fox Terrier and remained working terriers.  The size of the Russell Terrier (10″ to 12″) combined with a small flexible, spannable chest makes it an ideal size to work efficiently underground.  Their unique rectangular body shape with the body being of slightly longer length than the leg makes them distinctly different from the Parson Russell Terrier and the JRTCA Jack Russell Terrier.

American Cocker Spaniel: The American Cocker Spaniel is a breed of sporting dog.  It is a spaniel type dog that is closely related to the English Cocker Spaniel; the two breeds diverged during the 20th century due to differing breed standards in America and the UK.  In the United States, the breed is usually called the Cocker Spaniel, while elsewhere in the world, it is called the American Cocker Spaniel in order to differentiate between it and its English cousin, which was already known as "Cocker Spaniel" before the American variety was created.  The word "cocker" is commonly held to stem from their use to hunt woodcock in England, while "spaniel" is thought to be derived from the type's origins in Spain.

Canigou Cambrai: Ch.  Canigou Cambrai, also known as Albert (1992–2008), an English Cocker Spaniel, is the most recent of his breed to win best-in-show at Crufts in 1996, the seventh occasion it was awarded to a Cocker Spaniel and the first time for forty six years.  For a while he was the most successful black male Cocker Spaniel of all time in the UK, and his descendants continue to be multi-show winning champions around the world.

Cocker Spaniel: Cocker Spaniels are dogs belonging to two breeds of the spaniel dog type: the American Cocker Spaniel and the English Cocker Spaniel, both of which are commonly called simply "Cocker Spaniel" in their countries of origin.  In the early 20th century, Cocker Spaniels also included small hunting Spaniels.

Parson Russell Terrier: The Parson Russell Terrier is a breed of small white terrier that was the original Fox Terrier of the 18th century.  The breed is named after the person credited with the creation of this type of dog, the Reverend John "Jack" Russell.  It is the recognised conformation show variety of the Jack Russell Terrier and was first recognised in 1990 in the United Kingdom as the Parson Jack Russell Terrier.  In America, it was first recognised as the Jack Russell Terrier in 1997.  The name was changed to its current form in 1999 in the UK and by 2008 all international kennel clubs recognised it under the new name.

English Cocker Spaniel: The English Cocker Spaniel is a breed of gun dog.  The English Cocker Spaniel is an active, good-natured, sporting dog standing well up at the withers and compactly built.  There are "field" or "working" cockers and "show" cockers.  It is one of several varieties of spaniel and somewhat resembles its American cousin, the American Cocker Spaniel, although it is closer to the working-dog form of the Field Spaniel and the English Springer Spaniel.

Jack Russell Terrier: The Jack Russell Terrier is a small terrier that has its origins in fox hunting.  It is principally white-bodied and smooth, rough or broken-coated but can be any colour.

Jack Russell Terrier Club of America: The Jack Russell Terrier Club of America (JRTCA) is the largest Jack Russell Terrier club and registry in the world, and is the National Breed Club and Registry for the Jack Russell Terrier in the United States.
