Mitral Valve Disease (MVD) is one of the most important health concerns in Cavalier King Charles Spaniels. This breed is known for their loving personalities, beautiful companionship, and gentle nature, but they can be genetically predisposed to developing heart murmurs caused by changes in the mitral valve. Responsible breeders work hard to protect the future of the breed by making heart health a top priority.
Before breeding, Cavaliers should receive proper health testing, including a heart evaluation by a veterinarian and ideally a board-certified veterinary cardiologist. Breeding dogs should have their hearts checked regularly, with results documented through recommended health registries such as the Orthopedic Foundation for Animals (OFA). Responsible breeders also consider the age of the dog, family history, and breeding guidelines designed to reduce the risk of passing early-onset MVD to future generations.
At Tule Creek Cavaliers, we believe that every puppy deserves the healthiest start possible. Testing our dogs before breeding is not just a recommendation—it is a commitment to the puppies we bring into the world, the families who love them, and the future of this wonderful breed.
