Cavalier King Charles Spaniel
About the Cavalier King Charles Spaniel
Cavalier King Charles Spaniels were developed in England as refined toy spaniels, named after King Charles II who was so devoted to the breed that matters of state were neglected. These gentle, affectionate dogs combine the sporting spaniel heritage with a tractable, love-seeking temperament. They represent the quintessential gentle companion.
Temperament
Cavaliers are affectionate, gentle, and trusting companions who live to be near their people. They're eager to please, adaptable, and good with children and other pets, though somewhat sensitive souls.
Care Guide
Gentle daily exercise (30-45 minutes) keeps them healthy; they adapt well to apartment living. Regular brushing of their silky coat prevents matting, especially on feathering. They're prone to serious heart disease; regular vet checks including heart auscultation are essential.
