What Vets Say About Cavalier King Charles Spaniels

Cavaliers are the most expensive small breed to keep healthy. The heart disease is practically guaranteed — the question is when, not if. Syringomyelia is the second gut-punch: their skull is literally too small for their brain. Insurance with cardiac and neurological coverage is non-negotiable. Despite all this, they're one of the most popular breeds because the temperament is that good.
