King Charles Spaniel

Dog breed

Overview

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 coat colours now seen in the breed.

Thought to have originated in East Asia, and possibly acquired by European traders via the Spice Road, early toy spaniels were first seen in Europe during the 16th century. They became linked with English royalty during the rule of Queen Mary I (from 1553 to 1558), eventually earning their name after being made famous by their association with King Charles II. Ruling from 1660 to 1685, Charles II owned many small dogs which accompanied him and his entourage about their daily business. Members of the breed were also owned by Queen Victoria (Dash) and her great-granddaughter Grand Duchess Anastasia Nikolaevna of Russia.

The modern King Charles Spaniel, and the other types of toy spaniels, are likely the result of crossbreeding historic spaniels with other East Asian breeds (such as the Japanese Chin, Pekingese, and the Pug) in the early 19th century. This was done mainly to reduce the size of the nose and snout, as was the style of the day. The 20th century saw attempts to restore lines of King Charles Spaniels to the breed of Charles II's time. These included the unsuccessful Toy Trawler Spaniel and the now pop

Temperament

Temperament: The King Charles is a friendly breed, to the extent that it is not typically as suitable as a watchdog as some breeds, though it may still bark to warn its owners of an approaching visitor. It is not a high energy breed, and enjoys the company of family members, being primarily a lapdog. Although able to bond well with children and tolerant of them, it will not accept rough handling. It prefers not to be left alone for long periods. Known as one of the quietest toy breeds, it is suitable for apartment living.

The breed can tolerate other pets well, although the King Charles still has the hunting instincts of its ancestors and may not always be friendly towards smaller animals. It is intelligent enough to be used for obedience work and, due to its stable temperament, it can be a successful therapy dog for hospitals and nursing homes.

Appearance

Description: The King Charles has large dark eyes, a short nose, a high domed head and a line of black skin around the mouth. On average, it stands 9 to 11 inches (23 to 28 cm) at the withers, with a small but compact body. The breed has a traditionally docked tail, except in the UK and some other European Countries where docking and cropping has been illegal since 2006. Cropping of ears has been illegal in the UK for over 100 years. It has the long pendulous ears typical of a spaniel and its coat comes in four varieties, trait it shares with its offshoot, the Cavalier King Charles Spaniel.

The four sets of markings reflect the four former breeds from which the modern breed was derived. Black and tan markings are known as "King Charles", while "Prince Charles" is tricoloured, "Blenheim" is red and white, and "Ruby" is a single-coloured solid rich red. The "King Charles" black and tan markings typically consist of a black coat with mahogany/tan markings on the face, legs and chest and under the tail. The tricoloured "Prince Charles" is mostly white with black patches and mahogany/tan markings in similar locations to the "King Charles". The "Blenheim" has a white coat with red patches, and should have a distinctive red spot in the center of the skull.

King Charles Spaniels are often mistaken for Cavalier King Charles Spaniels. There are several significant differences between the two breeds, the principal being the size. While the Cavalier weighs on average between 13 and 18 pounds (5.9 and [dose — ask your vet]), the King Charles is smaller at 8 to 14 pounds (3.6 to [dose — ask your vet]). In addition, their facial features, while similar, are distinguishable: the Cavalier's ears are set higher and its skull is flat, while the King Charles' is domed. Finally, the muzzle length of the King Charles tends to be shorter than the typical muzzle on a Cavalier.

The American Kennel Club has two classes, English Toy Spaniel (B/PC) (Blenheim and Prince Charles) and English Toy Spaniel (R/KC), while in the UK, the Kennel Club places the breed in a single class. Under the Fédération Cynologique Internationale groups, the King Charles is placed in the English Toy Spaniel section within the Companion and Toy Dog Group, along with the Cavalier King Charles Spaniel.

Health

Health: A natural bobtail can be found in some members of the breed, which is not a mutation of the T-box gene, and so is allowed under conformation show rules. Health-related research on the breed has been limited, with no major studies conducted in Britain. However, it has been included in studies outside the UK, including by the Orthopedic Foundation for Animals (OFA) in the United States. The King Charles Spaniel has a number of eye and respiratory system disorders common to brachycephalic dogs, and endocrine and metabolic diseases common to small breeds, as well as specific breed-associated health conditions. The average lifespan is 10 to 12 years, and the breed should be able to reproduce naturally.

History

History: The King Charles Spaniel may share a common ancestry with the Pekingese and Japanese Chin.

The red and white variety of toy spaniel was first seen in paintings by Titian, including the Venus of Urbino (1538), where a small dog is used as a symbol of female seductiveness. Further paintings featuring these toy spaniels were created by Palma Vecchio and Paolo Veronese during the 16th century. These dogs already had high domed heads with short noses, although the muzzles were more pointed than they are today. These Italian toy spaniels may have been crossed with local small dogs such as the Maltese and also with imported Chinese dogs. The Papillon is the continental descendant of similar toy-sized spaniels.

The earliest recorded appearance of a toy spaniel in England was in a painting of Queen Mary I and King Philip. Mary, Queen of Scots, was also fond of small toy dogs, including spaniels, showing the fondness of the British royalty for these types of dogs before Charles II.

Every pet is one of a kind.
