This week’s dog is a well-known breed that we see everywhere. They are cute, loyal and loving: the 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.
Cocker Spaniels were originally bred as hunting dogs in the United Kingdom, with the term cocker deriving from their use to hunt the Eurasian woodcock. When the breed was brought to the United States, it was bred to a different standard, which enabled it to specialize in hunting the American woodcock. Further physical changes were bred into the cocker in the United States during the early part of the 20th century.
Spaniels were first mentioned in the 14th century by Gaston III of Foix-Béarn in his work the Livre de Chasse. The “cocking” or “cocker spaniel” was a type of field or land spaniel in the 19th century. Prior to 1901, Cocker Spaniels were only separated from Field Spaniels and Springer Spaniels by weight. Two dogs are considered to be the foundation sires of both modern breeds, the English variety are descended from Ch. Obo, while the American breed descends from Obo’s son, Ch. Obo II. In the United States, the English Cocker was recognized as separate from the native breed in 1946; in the UK, the American type was recognized as a separate breed in 1970. In addition, there is a second strain of English Cocker Spaniel, a working strain which is not bred to a standard but to working ability. Both breeds share similar coat colors and health issues with a few exceptions.

Description
There are two modern breeds of cocker spaniel, the English Cocker Spaniel and the American Cocker Spaniel. They were bred as gun dogs; to use their sense of smell to cover low areas near the handler in order to flush birds into the air to be shot, and to use their eyes and nose to locate the bird once downed, and then to retrieve the bird with a soft mouth. The major differences between the English and American varieties is that the American is smaller with a shorter back, a domed head and a shorter muzzle, while the English variety is taller with a narrower head and chest.
Cocker spaniel coats come in a variety of colors including black, liver, red and golden in solids. There are also black and tan, and sometimes liver and tan, as well as a variety of color mixtures of those solid colors including roans, roan and tans, tricolors and those solid colors with additional white markings.
Rare colours can appear unexpectedly in certain lines, for instance while an all-white cocker is usually bred by selective breeding of very light golden strains, they can still appear very uncommonly to parents who are dark colored. A noted occurrence of this happened in 1943, when a grandson of My Own Brucie, Best in Show at the Westminster Kennel Club Dog Show in 1940 and 1941, was born all-white.
In its native United States, the American Cocker Spaniel was ranked the 23rd most popular breed according to registration statistics of the AKC in 2009, a decrease in popularity since 1999 when it was ranked 13th. For twenty five years the American Cocker Spaniel was the most popular dog in America. It was ranked number one first in 1936 prior to the English Cocker Spaniel being recognized as a separate breed, and held onto the spot until 1952 when Beagles became the most popular dog. It regained the spot in 1983 and held on at number one until 1990. In the UK, the American Cocker Spaniel is far less popular than its English cousin with 322 registrations compared to the English Cocker’s 22,211 in 2009.
History
While their origins are unknown, “spaynels” are mentioned in 14th century writings. It is commonly assumed that they originated in Spain, and Edward of Norwich, 2nd Duke of York in his 15th century work The Master of Game introduces them as “Another kind of hound there is that be called hounds for the hawk and spaniels, for their kind cometh from Spain, notwithstanding that there are many in other countries.” The Master of Game was mostly an English translation of an earlier 14th century Old French work by Gaston III of Foix-Béarn entitled Livre de Chasse.
In 1801, Sydenham Edwards wrote in Cynographia Britannica that the “Land Spaniel” is divided into two types: the hawking, springing/springer and the cocking/cocker spaniel. The term cocker came from the dog’s use in hunting woodcocks. During the 19th century a “cocker spaniel” was a type of small Field Spaniel; at the time, this term referred to a number of different spaniel hunting breeds, including the Norfolk Spaniel, Sussex Spaniel, and Clumber Spaniel. While there were no Sussex Cockers or Clumber Cockers, there were dogs known as Welsh Cockers and Devonshire Cockers. The Welsh or Devonshire were considered cockers until 1903 when they were recognized by The Kennel Club as the Welsh Springer Spaniel.
Prior to the 1870s, the only requirement for a dog to be classed as a Cocker Spaniel was that it needed to weigh less than 25 pounds (11 kg), although breeders separated the cocker from the King Charles Spaniel which remains a smaller breed of spaniel. This maximum weight limit remained on the Cocker Spaniel until 1900, with larger dogs being classed as Springer Spaniels. The colors of the Devonshire and Welsh Cockers were described by John Henry Walsh under the pseudonym Stonehenge in his book The Dog in Health and Disease as being a deeper shade of liver than that of the Sussex Spaniel. Following the formation of The Kennel Club in the UK in 1873, efforts were made by breeders to record the pedigrees of cockers and springers. In 1892, English Cocker Spaniels and English Springer Spaniels were recognized as separate breeds by The Kennel Club.
There are two dogs which are thought to be the foundation sires of both modern breeds of cocker spaniels. Ch. Obo is considered by breed enthusiasts to be the father of the modern English Cocker Spaniel, while his son, Ch. Obo II, is considered to be the progenitor of the American Cocker Spaniel. Obo was born in 1879, at which point registration as a cocker was still only by size and not by ancestry. He was the son of a Sussex Spaniel and a Field Spaniel. Although Obo was an English dog, Obo II was born on American shores – his mother was shipped to the United States while pregnant. During his lifetime, it was claimed in advertisements that Obo II was the sire or grandsire of nearly every prize winning cocker in America.
