Mitral Valve Disease- MVD is a condition of the heart affecting virtually 100% of all Cavs. The disease is characterized by a murmur that worsens over time and eventually leads to heart failure. It is possible to reduce the early onset of this disease by selective breeding, but needless to say, puppymills and backyard breeders rarely follow these guidelines. Please learn all you can about puppymills, pet store puppies and backyard breeders before you begin a search for any pure breed dog. You can start by reading our FAQ page.

Syringomyelia- Cerebrospinal fluid transports waste products from around the brain and spinal cord and serves as a cushion for the brain. Any obstruction in the normal flow of this fluid is characterized as SM. It is believed that nearly half of all Cavaliers have or will acquire this condition. One leading cause is Occipital Hypoplasia (a skull bone malformation). Symptoms usually appear between 6 months and 3 years of age and include localized pain around the head, neck and shoulders, odd scratching behaviors and clumsiness and falling. There is currently no cure.

Hip Dysplasia is a developmental subluxation of the hip joints which can eventually lead to arthritis and/or lameness. It's causes are genetic as well as environmental. A secondary concern of this affliction is osteoarthritis.

The use of pet steps has been shown to significantly reduce the wear and tear on joints. Please consider them if you own or plan to own a Cavalier King Charles Spaniel.

Keratoconjunctivitis Sicca- A reduction in the natural production of tears. An easier term is "Dry Eye". This condition requires continual treatment to avoid blindness or partial blindness. This is another condition affecting Cavalier King Charles Spaniels all too commonly.
