Origin and Development

The King Charles Spaniel, known as the English Toy Spaniel in the USA, originated in England and was developed by combining four separate toy spaniel breeds in 1903 under the single title. These breeds included the Blenheim, Ruby, Prince Charles Spaniels, each contributing one of the four coat colours seen in the breed today.

Thought to have originated in East Asia, the early toy spaniels first appeared in Europe during the 16th century, likely brought by European traders via the Spice Road. They were linked with English royalty during the rule of Queen Mary I from 1553 to 1558, and their name was ultimately associated with King Charles II, who was very fond of the breed.

King Charles II, reigning from 1660 to 1685, owned many small dogs that accompanied him and his entourage, which increased the breed's popularity during his time. The modern King Charles Spaniel is 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 to reduce the size of the nose and snout, a style popular at the time.

Physical Characteristics

The King Charles Spaniel is a small, compact toy spaniel with distinctive features. It has a domed head, flat face, short nose, large dark eyes, long ears, and a silky coat available in four color varieties: Blenheim, Tricolour, Ruby, and Black and Tan.

The breed stands at an average height of 23 to 28 cm at the withers and weighs between 3.6 to 6.3 kg. It has long pendulous ears typical of a spaniel and a traditionally docked tail, except in the UK and some other European countries where docking and cropping have been illegal since 2006.

The King Charles Spaniel has a naturally bobtail, which is not a mutation of the T-box gene and is allowed under conformation show rules. The breed is known for its large dark eyes, a short nose, and a high domed head, with a line of black skin around the mouth.

Temperament and Personality

The King Charles Spaniel is known for its gentle, affectionate, intelligent, friendly, happy, and playful temperament. It is a small dog with a high energy level and high friendliness, making it an excellent choice for families or individuals looking for a loyal companion.

Despite its hunting instincts, the King Charles Spaniel is not well suited for field sports due to its small stature. Instead, it is better suited to being a lapdog, which is a role it has fulfilled throughout history, including being referred to as "Comforters" in the 16th century, dogs believed to have healing properties.

The breed's intelligence and trainability are high, making them easy to train and a good fit for owners willing to invest time in training and socialization.

Health Considerations

Despite its charm, the King Charles Spaniel is prone to several health problems, including cardiac conditions and a range of eye problems common in brachycephalic dogs, such as cataracts, corneal dystrophy, distichia, entropion, microphthalmia, optic disc drusen, and keratitis. The breed also has an increased risk of distichia, where extra eyelashes or hairs cause irritation to the eye.

Heart conditions associated with the King Charles Spaniel include mitral valve disease, where the mitral valve degrades, causing blood to flow backward through the heart chambers and leading to congestive heart failure, and patent ductus arteriosus, a condition where the vessel connecting the aorta to the pulmonary artery remains open after birth.

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.

History of the Breed

The King Charles Spaniel's history is intertwined with that of English royalty. Queen Mary I was an early enthusiast of the breed, and King Charles II, who ruled from 1660 to 1685, was particularly fond of them. His ownership and association with the breed increased its popularity.

During the 17th century, the breed began to feature in paintings by Dutch and Spanish artists, depicting the dogs in tricolour, black and white, or entirely white. King Charles II's fondness for the breed was documented by Samuel Pepys in his diary, detailing how the spaniels were allowed to roam freely in Whitehall Palace, even during state occasions.

Following the Glorious Revolution in 1688, the Pug was introduced into Britain, which led to significant physical changes in the King Charles Spaniel. The breed continued to be popular throughout the 18th and 19th centuries, often featured in literature and art, and remained a favorite among the upper classes.

Conformation Showing and the 20th Century

In 1903, the Kennel Club attempted to amalgamate the various toy spaniel breeds into a single breed called the Toy Spaniel. However, the Toy Spaniel Club strongly objected, and the name "King Charles Spaniel" was eventually chosen, in part due to King Edward VII's preference.

Throughout the 20th century, the breed continued to be popular with royalty, including Princess Margaret, Countess of Snowdon, who attended her daughter's birthday party with her dog Rolly in 1960. The Cavalier King Charles Spaniel, a larger and slightly different breed, originated from a competition held by American Roswell Eldridge in 1926 and was recognized by the Kennel Club in 1945.

Attempts to restore the breed to its original appearance, as seen in the portraits of King Charles II, have been documented by breeders and enthusiasts, though challenges remain due to the breed's historical changes and mixed ancestry.
