Cavalier King Charles Spaniel overview
The AKC places the Cavalier King Charles Spaniel in the Toy Group and lists England as its origin. VCA Animal Hospitals describes Cavaliers as small companion dogs with a gentle temperament and a strong attachment to people.
Where does the Cavalier come from?
The United Kennel Club says small toy spaniels were known in Europe and Great Britain from the 16th century and were often ladies' pets. During the reign of King Charles II these dogs received the royal title King Charles Spaniel, and the Cavalier descends from them. Shorter-faced show lines became the English Toy Spaniel, while dogs closer to the old paintings became known as the Cavalier, after a prize offered by an American named Roswell Eldridge.
