As a breeder of registered Cavaliers with many years of experience, the Cavalier KC Spaniels average life span is 12 to 14 years. Just because the parents are Certified in no way eliminates a baby of hereditary disease. There are four generations that come into play. It does give some reassurance however that the PARENTS were healthy. How YOU care for your baby will make a huge difference in your Cavaliers lifespan.
