Quick Answer: Cavalier King Charles Spaniels are among the most gentle, loving, and easy-going breeds available — perfect for families, seniors, and apartment living. They're also a breed with a serious inherited cardiac concern: Mitral Valve Disease (MVD) affects nearly all Cavaliers to some degree by age 10, and is the leading cause of death in the breed. Annual cardiac screening is essential from age 5.
The Heart Reality
MVD (Mitral Valve Disease) is so prevalent in the breed that cardiac testing protocols exist specifically for Cavaliers. The Cavalier Health Organization's Breeding Protocol recommends that breeding dogs be clear of MVD at specific ages before producing offspring. As a pet owner, annual cardiac checks (listening to the heart for the characteristic murmur) from age 5 allow early detection and appropriate management.
What They Need Daily
45-60 minutes of gentle exercise. They're not a high-intensity breed — they're companion dogs who walk happily, play quietly, and are equally content cuddling on a calming bed. Their exercise needs make them one of the best breeds for seniors, apartment dwellers, and people with more moderate activity levels. Mental enrichment through a lick mat or snuffle mat keeps their gentle intelligence satisfied.
Separation Anxiety
Cavaliers were bred to be with their person constantly. They can develop significant separation anxiety if not taught independence from puppyhood. A frozen lick mat at departure and gradual alone-time building prevents this from becoming a serious issue.
