The Cavalier King Charles Spaniel as we know it today was not given official Kennel Club recognition until 1945. The King Charles Spaniel whose history has been documented since the 15th Century has its origins in the courts of Europe. In 2000 only 185 King Charles Spaniel puppies were registered with the U.K. Kennel Club while the registrations for Cavalier King Charles Spaniel puppies exceeded 11,400.
