The Cavalier King Charles Spaniel is a small toy spaniel from England, revived in the 1920s to match the longer-nosed lap dogs seen in portraits from King Charles II's era. The AKC recognized the breed in 1995. Cavaliers have large dark eyes, long feathered ears and a silky coat in Blenheim, tricolor, ruby or black and tan.
Most are gentle, affectionate and adaptable, and many get along with children, other dogs and cats. Their sweetness comes with serious health risks: nearly all develop mitral valve heart disease eventually, and many carry a skull malformation linked to syringomyelia. In a hot place like Scottsdale, that heart risk is one more reason to watch how a Cavalier handles warm weather, and to budget for veterinary care from the start.
