The Cavalier King Charles Spaniel is a small spaniel classed as a toy dog by The Kennel Club and the American Kennel Club, that originated in the United Kingdom. The breed has four recognized colors. This color is referred to as 'Prince Charles' in the King Charles Spaniel. As such, dogs of the breed are good with children and other dogs. Cavaliers are not shy about socializing with much larger dogs. They will adapt quickly to almost any environment, family, and location and suit city and country life. Their ability to bond with larger and smaller dogs makes them ideal in houses with more than one breed of dog as long as the other dog is trained.
