Cavalier King Charles Spaniel

The Cavalier King Charles Spaniel is a small breed of Spaniel-type dog, and is classed as a Toy dog
by most Kennel Clubs. It is one of the most popular breeds in the United Kingdom.
Since 2000, it has been growing in popularity in the United States. It is a smaller breed of Spaniel, and  Cavalier adults are often the same size as adolescent dogs of other spaniel breeds. It has a silky coat and commonly an undocked tail. The breed standard recognizes four colours (Blenheim, Tricolour [black/white/tan], Black and Tan, and Ruby). The breed is generally friendly, affectionate and good with both children and other animals.
The King Charles had changed drastically in the late 1600s, when it was interbred with flat-nosed breeds. Until the 1920s, the Cavalier shared the same history as the smaller King Charles Spaniel. Breeders  attempted to recreate what they considered to be the original configuration of the breed, a dog resembling
Charles II's King Charles Spaniel of the Restoration.
Various health issues affect this particular breed, most notably mitral valve disease, which leads to heart
failure. This will appear in most Cavaliers at some point in their lives and is the most common cause of death. The breed may also suffer from Syringomyelia, a malformation of the skull that reduces the space available for the brain. Cavaliers are also affected by ear problems, a common health problem among spaniels of
various types, and they can suffer from such other general maladies as hip dysplasia, which are common  across many types of dog breeds.
