While their origins are unknown, "spaynels" are mentioned in 14th-century writings. They are commonly assumed to have originated in
Spain, and
Edward, 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 no Sussex Cockers or Clumber Cockers existed, some dogs were 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. This maximum weight limit remained on the Cocker Spaniel until 1900; larger larger dogs were then 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. Two dogs are considered 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. During his lifetime, Obo II was claimed in advertisements to be the sire or grandsire of nearly every prize-winning cocker in America. ==Modern breeds==
