Cavalier King Charles Spaniels typically live twelve to fifteen years when provided proper care, though the breed faces significant health challenges that affect both longevity and quality of life. Prospective owners must understand these health issues and choose breeders who conduct thorough health testing on breeding stock. The breed's history of descending from a small founding population has contributed to the prevalence of certain genetic conditions.
Mitral valve disease represents the most serious and common health problem affecting Cavalier King Charles Spaniels. This progressive heart condition involves degeneration of the mitral valve, which normally prevents blood from flowing backward in the heart. As the valve deteriorates, it leaks, causing the heart to work less efficiently. Studies suggest more than half of all Cavaliers develop a heart murmur by age five, with many progressing to congestive heart failure as they age. Mitral valve disease is the leading cause of death in this breed.
Early detection of mitral valve disease through regular cardiac examinations allows for intervention that may slow progression and extend quality life. Veterinary cardiologists can conduct echocardiograms and other tests to assess heart function and guide treatment decisions. Medications including ACE inhibitors and other cardiac drugs help manage symptoms and slow disease progression. Responsible breeders have their breeding dogs examined annually by board-certified cardiologists and only breed dogs remaining clear of heart murmurs past certain ages.
Syringomyelia represents another serious neurological condition affecting Cavaliers more than most other breeds. This painful disorder occurs when the skull is too small for the brain, causing cerebrospinal fluid to be forced into the spinal cord, creating fluid-filled cavities called syrinxes. Affected dogs may show sensitivity around the head and neck, phantom scratching near the head without making contact with skin, whining or crying when touched, and in severe cases, paralysis. MRI scans can diagnose syringomyelia, though not all affected dogs show clinical signs.
Treatment for syringomyelia focuses primarily on managing pain through medications, though severe cases may require surgical intervention to improve cerebrospinal fluid flow. The condition can significantly impact quality of life, and prospective owners should seek breeders who MRI scan their breeding stock to identify affected dogs and make informed breeding decisions. While complete elimination of the condition remains challenging given its prevalence, responsible breeding practices help reduce severity and incidence.
Hip dysplasia affects Cavaliers despite their small size, causing malformation of the hip joint that can lead to arthritis and mobility problems. The Orthopedic Foundation for Animals ranks Cavaliers in the middle range for hip dysplasia prevalence among dog breeds. X-rays can detect hip dysplasia, allowing breeders to make informed decisions about breeding stock. Maintaining healthy weight throughout life reduces stress on dysplastic hips, while moderate exercise helps maintain muscle support around joints.
Eye problems including cataracts, retinal dysplasia, and dry eye can affect Cavaliers. Regular eye examinations by veterinary ophthalmologists detect developing conditions early, allowing treatment to preserve vision. Cherry eye, a condition where the gland of the third eyelid prolapses, occasionally occurs in young Cavaliers and requires surgical correction. Responsible breeders have their breeding dogs examined annually by board-certified ophthalmologists.
Luxating patella, where the kneecap dislocates from its normal position, affects many small breeds including Cavaliers. Mild cases may cause occasional skipping or hopping but resolve quickly, while severe cases require surgical correction. Maintaining healthy weight reduces stress on the knee joints, while appropriate exercise builds supporting muscles.
Regular veterinary care throughout life allows early detection of health problems before they become severe. Annual wellness examinations should include cardiac auscultation to detect heart murmurs, physical assessment of joints and overall condition, and discussion of any behavioral or health changes. Blood work helps monitor organ function, particularly as dogs age. Dental care through professional cleanings and home tooth brushing prevents periodontal disease that can affect overall health.
Proper nutrition supports the Cavalier's health throughout life stages. High-quality dog food appropriate for the dog's age provides necessary nutrients without excessive calories. Cavaliers can easily become overweight if overfed, and obesity exacerbates many health problems including heart disease, hip dysplasia, and diabetes. Measuring food portions and limiting treats to no more than ten percent of daily calories helps maintain healthy weight.
