A brief introduction to Cavalier King Charles Spaniel
The descendants of Cavalier King Charles Spaniel were thought to have been brought to Scotland from continental Europe in 1500s.
The 1st Duke of Marlborough, John Churchill, had a number of red and white King Charles type spaniels for hunting. Churchill named his estate Blenheim in honour of his victory at the Battle of Blenheim, which in turn led to the red and white members of the Cavalier King Charles Spaniel getting the name Blenheim.
The dog breed was in vogue with the royals and noble as a lap dog and some claim that they were allowed to sleep with their masters in the bed to attract fleas and prevent the monarchs catching diseases.
King Charles II was particularly fond of these affectionate dogs, especially the black and tan variety, which have gone on to be named after him. It is believed that King Charles II usually had two or three of these pooches by his side.
Indeed, Samuel Pepys, who was Chief Secretary to King Charles II, remarked that the monarch seemed more concerned about breeding his spaniels rather than ruling the country. Pepys went on to describe how King Charles II allowed his spaniels to roam around Whitehall Palace even during state occasions.
When King Charles II died in 1685, their popularity suffered. The breed was mixed with Asian toy breeds from the reign of Queen Victoria onwards to slightly alter the appearance of these dogs that King Charles II was so fond of.
However, American Roswell Eldridge helped to rekindle the old features of the Cavalier King Charles Spaniel when the wealthy businessman offered a cash prize to British breeders who could revive the breed’s old style. It was at this juncture a distinction between the King Charles Spaniel and Cavalier King Charles Spaniel was made.
While Eldridge died before seeing the return of the old style, he inspired a group to set up the first Cavalier club which led to the Kennel Club outlining the breed’s standard. World War II hampered the breed’s development and they nearly went extinct but a few survived and are believed to be the descendants of modern day Cavalier King Charles Spaniels.
Remarkably, the first Cavalier King Charles Spaniel didn’t make it to the United States until 1956. W. Lyon Brown was the first American to own a member of the breed in USA and she was one of the founding members of the Cavalier King Charles Club USA. The breed received recognition by the United Kennel Club in 1995.
What breeds make Cavalier King Charles Spaniel?

The King Charles also goes by the name black and tan and these were the favourite variety of King Charles II. They usually have some tan markings on their face set against a black background.
Ruby or rich mahogany Cavalier King Charles Spaniels should have ruby or red coats in their entiriety. Some may have splashes of white but the AKC views this as a fault in the breed.
