«1.    HEART............................... Chronic, degenerative mitral valve disease.  The first indication is a murmur.  Other
                        heart defects include pulmonary and aortic stenoses and PDA.  Certification should be done by a
                        board certified veterinary cardiologist.    

«2.     EYES.................................. Juvenile cataracts and retinal dysplasia or folds.  Progressive retinal atrophy (PRA) has also occurred in Cavaliers.  A board certified veterinary ophthalmologist should give a final diagnosis.  

«3.     PATELLAR LUXATION........ Even quite bad patellar luxation may not cause much, if any, discomfort; especially while the Cavalier is young.  Surgery is an option if the Cavalier is in pain, his quality of life is impaired or to prevent irreversible joint deterioration.  

«4.     HIP DYSPLASIA.................. If hip problems are suspected or hip x-rays are taken for any reason, those x-rays must be submitted to the OFA for diagnostic and statistical reasons.  Final x-rays for hip dysplasia can be taken at 2 years of age or older if they are sent to the OFA.  Preliminary hip x-rays can be sent to the OFA at any age.  Because of the breed’s small size, obvious clinical symptoms usually don’t occur until the Cavalier is older and then mainly in severely affected dogs only.  

    5..     BACK................................. Degenerative disc disease, spondylosis.  

   6.     EPILEPSY........................... Gran mal seizures are possible but various forms of focal (i.e. - petit mal) seizures can also occur.  The most common focal seizure is called “Fly Catcher’s Syndrome”, where the dog snaps or lunges at imaginary flies.  There are many other types of focal seizures that can occur.  All types of seizures may be treated with phenobarbital and/or potassium bromide if necessary.

   7.     DEAFNESS......................... Total deafness is rarely congenital.  Cavalier deafness is usually of a partial and/or premature nature.  Some Cavaliers become totally deaf by 6-8 years.  

   8.     IMMUNE SYSTEM.............. These can include, but are not limited to, allergies, digestive or metabolic disorders, dry eye, cancer, fertility and/or breeding problems, muscle or nerve disorders, thyroid problems, blood problems (mainly autoimmune hemolytic anemia and/or thrombocytopenia), diabetes etc.  

    9.     SYRINGOMYELIA (“SM”)... A problem caused by an overly small occipital bone (part of the back of the skull), thus preventing cerebrospinal fluid from circulating freely.  The fluid is forced into the spinal cord creating a cavity called syringomyelia.  The most common sign of this condition is shoulder/neck/ear scratching (with no evidence of skin or ear disease), especially when excited or walking on a lead – typically to one side only but may become bilateral.  Affected dogs are also sensitive around the head, neck and forelimbs and often cry/yelp/scream for apparently no reason.  Pain may be related to head posture and some dogs prefer to sleep or eat with their heads up.  Some severely affected young dogs develop a neck scoliosis, i.e. – their neck is twisted.  Some dogs may develop a wobbling hind limb gait and/or a forelimb weakness.  Signs are usually recognised between 6 months and 3 year, however dogs of any age may begin showing symptoms.  The only definite way to diagnose syringomyelia and the associated skull malformation is by a MRI scan.  Unfortunately this expensive test is only available at specialist veterinary centers.

 «    Problems which are diagnosed through simple, non-invasive, inexpensive, readily available, painless tests.  A breeder should ANNUALLY test their adults’ heart, eyes and patellas.  Hip dysplasia can be definitively diagnosed by OFA with hip x-rays taken at a minimum of 24 months.  The other problems are diagnosed if/when symptoms appear.  

Almost none of these problems are congenital (i.e. - present at birth) but develop sometime later on with no upper age limit for age of onset.  Positive test results (pre-symptomatically) or actual symptoms generally show up between 2 and 6 years of age, although younger and older ages of onset are possible.

Breed-wide, the average lifespan of a Cavalier is about 9-10 years.  

For more detailed information about all aspects of your Cavalier, go to http://www.ckcsc.org.  Under Health Information, Diseases and Disorders, there is more detailed information about specific health issues in the Cavalier. 

Under Health Information, Health Registry, there is a VIEW BY menu to search Cavaliers by Name, by Breeder, by Owner and by those who are 5+ years old with a cardiologist's clear heart certificate.  Look up the breeder or parents of your puppy!  Many breeders and/or owners have submitted their dogs to this Open Health Registry hoping that the CKCSC's FREE service will help promote longer lived and healthier dogs by making health records openly available.  For the future of Cavaliers, it is important to have participation by all owners, breeders, and pet owners alike.
