History of the Cavalier King Charles Spaniel
Toy spaniels were favourites of the British aristocracy for centuries and were associated with King Charles II. Over time, the breed’s muzzle became shorter, giving rise to the King Charles Spaniel.
In the 1920s, an American named Roswell Eldridge offered a prize at Crufts for spaniels resembling those in old royal portraits, with longer noses and flatter heads. Breeders responded, and the Cavalier King Charles Spaniel was recognised as a separate breed in 1945.
Fun fact
The breed is named after King Charles II of England, who was famously devoted to his small spaniels.
