Question: Are the English Cocker Spaniel and Jack Russell Terrier large dog breeds?

full_context: Document 1: 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.
Document 2: English Springer Spaniel: The English Springer Spaniel is a breed of gun dog in the Spaniel family traditionally used for flushing and retrieving game. It is an affectionate, excitable breed with a typical lifespan of twelve to fourteen years. They are very similar to the Welsh Springer Spaniel and are descended from the Norfolk or Shropshire Spaniels of the mid-19th century; the breed has diverged into separate show and working lines. The breed suffers from average health complaints. The show-bred version of the breed has been linked to "rage syndrome", although the disorder is very rare. It is closely related to the Welsh Springer Spaniel and very closely to the English Cocker Spaniel; less than a century ago, springers and cockers would come from the same litter. The smaller "cockers" hunted woodcock while the larger littermates were used to flush, or "spring," game. In 1902, The Kennel Club recognized the English Springer Spaniel as a distinct breed. They are used as sniffer dogs on a widespread basis. The term "Springer" comes from the historic hunting role, where the dog would flush (spring) birds into the air.
Document 3: Spaniel: A spaniel is a type of gun dog. Spaniels were especially bred to flush game out of denser brush. By the late 17th century spaniels had been specialized into water and land breeds. The extinct English Water Spaniel was used to retrieve water fowl shot down with arrows. Land spaniels were setting spaniels—those that crept forward and pointed their game, allowing hunters to ensnare them with nets, and springing spaniels—those that sprang pheasants and partridges for hunting with falcons, and rabbits for hunting with greyhounds. During the 17th century, the role of the spaniel dramatically changed as Englishmen began hunting with flintlocks for wing shooting. Charles Goodall and Julia Gasow (1984) write that spaniels were "transformed from untrained, wild beaters, to smooth, polished gun dogs."
Document 4: 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.
Document 5: Smooth Fox Terrier: The Smooth Fox Terrier is a breed of dog, one of many terrier breeds. It was the first breed in the fox terrier family to be given official recognition by The Kennel Club (circa 1875; breed standard 1876). It is well known, and although not a widely popular breed today outside of hunting and show circles, it is extremely significant due to the large number of terriers believed descended from it.
Document 6: 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.
Document 7: 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.
Document 8: Border Terrier: The Border Terrier is a small, rough-coated breed of dog in the terrier group. Bred as a fox and vermin hunter, the Border Terrier shares ancestry with the Dandie Dinmont Terrier and the Bedlington Terrier.
Document 9: Fox Terrier: 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.
Document 10: 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.
Document 11: Welsh Springer Spaniel: The Welsh Springer Spaniel is a breed of dog and a member of the spaniel family. Thought to be comparable to the old Land Spaniel, they are similar to the English Springer Spaniel and historically have been referred to as both the Welsh Spaniel and the Welsh Cocker Spaniel. They were relatively unknown until a succession of victories in dog trials by the breed increased its popularity. Following recognition by The Kennel Club in 1902, the breed gained the modern name of Welsh Springer Spaniel. The breed's coat only comes in a single colour combination of white with red markings, usually in a piebald pattern. Loyal and affectionate, they can become very attached to family members and are wary of strangers. Health conditions are limited to those common among many breeds of dog, although they are affected more than average by hip dysplasia and some eye conditions. They are a working dog, bred for hunting, and while not as rare as some varieties of spaniel, they are rarer than the more widely known English Springer Spaniel with which they are sometimes confused.
Document 12: Cavalier King Charles Spaniel: The Cavalier King Charles Spaniel is a small spaniel classed as a toy dog by The Kennel Club and the American Kennel Club. It originated in the United Kingdom and is one of the more popular breeds in many countries. Since 2000, it has grown in popularity in the United States and ranks as the 18th most popular pure-breed in the United States (2013 Registration Statistics). It has a silky, smooth coat and commonly a smooth undocked tail. The breed standard recognizes four colours: Blenheim (chestnut and white), Tricolor (black/white/tan), Black and Tan, and Ruby. The breed is generally friendly, affectionate and good with both children and other animals; however, they require a lot of human interaction. Since they are a family dog, it is recommended to not leave them alone for long periods at a time. The expected average lifespan of a Cavalier King Charles Spaniel is under ten years.
Document 13: Miniature Fox Terrier: The Miniature Fox Terrier is a small, fine, lightweight working terrier developed as a hunting dog and vermin router. It is known colloquially in its native Australia as the “Mini Foxie”.
Document 14: English White Terrier: The English white terrier (also known as the White English terrier or Old English terrier) is an extinct breed of dog. The English White terrier is the failed show ring name of a pricked-ear version of the white fox-working terriers that have existed in Great Britain since the late 18th Century.
Document 15: 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.
