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.
The Toy Trawler Spaniel is an extinct breed of Spaniel which physically was similar to the King Charles Spaniel of the 16th century.
 It is considered to have descended from the original King Charles Spaniel, and the older variety of Sussex Spaniel.
 It was originally used as a sporting dog, but became used as a toy and show dog.
 It was considered to be on the verge of extinction by 1920.
 A preserved specimen is kept in Tring at the Natural History Museum.
The Alpine Spaniel is an extinct breed of dog which was used in mountain rescues by the Augustinian Canons, who run hospices in the region around the Great St. Bernard Pass.
 The spaniel was a large dog notable for its thick curly coat.
 One of the most famous specimens of the Alpine Spaniel is Barry, however his preserved body has been modified on more than one occasion to fit with descriptions of the extinct breed from earlier time periods.
 Due to the conditions in the Alps, and a series of accidents, extinction was discussed as a possibility by authors during the 1830s, and at some point prior to 1847 the entire breed was reduced to a single example due to disease.
 Evidence held at the Natural History Museum in Bern show that two distinct breeds of dog were being used in the area during this time period.
 The breed is thought to be the predecessor to the modern St. Bernard and the Clumber Spaniel.
The Taigan (Kyrgyz: Тайган ) also known as Kyrgyzdyn Taighany (Kyrgyzskaya Borzaya Taigan in Russian) is a sighthound breed from Kyrgyzstan, which is not yet recognized by the FCI, but is recognized by a number of kennel clubs on national level.
The King Charles Spaniel (also known as the English Toy Spaniel) is a small dog breed of the spaniel type.
 In 1903, the Kennel Club combined four separate toy spaniel breeds under this single title.
 The other varieties merged into this breed were the Blenheim, Ruby and Prince Charles Spaniels, each of which contributed one of the four colours available in the breed.
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).
The Picardy Spaniel is a breed of dog developed in France for use as a gundog.
 It is related to the Blue Picardy Spaniel, and still has many similarities, but the Picardy Spaniel is the older of the two breeds.
 It is thought to be one of the two oldest continental spaniel breeds and was favoured by the French nobility, remaining popular for hunting after the French Revolution due to its weather resistant coat that enabled it to hunt in a variety of conditions and terrain.
 However its popularity waned following the influx of English hunting breeds in the early 20th century.
 Slightly smaller than an English Setter but larger than most of its spaniel cousins, it has no major health issues although as with many breeds with pendulous ears, it can be prone to ear infections.
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.
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.
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."
