If the spaniels are built for royalty, that means the Cavalier King Charles Spaniel is king. This regal toy spaniel dates back to the Renaissance, where King Charles I and his son Charles II were particularly fond of the breed. Eventually, the cavalier was dubbed after their namesake. Well into the 19th century, cavaliers were a favorite among British aristocrats, and they bred different varieties of this special toy breed.
Known for their distinctive coloring, the cavalier has four main color patterns: Tricolor (with black markings on white) Blenheim (chestnut markings on white) black and tan, and ruby (a deep orangy-red.) Historically, these colors signify what royal family your particular cavalier may have come from.
