Common Health Issues in Cavalier King Charles Spaniels

While Cavalier King Charles Spaniels are generally known for their friendly temperament and striking appearance, they, unfortunately, come with a predisposition to several health issues. Understanding these concerns is crucial for any owner or potential owner. Regular veterinary check-ups and a keen eye for early symptoms can make a significant difference in managing these conditions.

Mitral Valve Disease (MVD)

One of the most prevalent health issues in this breed is Mitral Valve Disease. This heart condition typically manifests in middle-aged to older dogs but can appear earlier. MVD involves the deterioration of the heart’s mitral valve, leading to a heart murmur and potentially progressing to heart failure. Early detection through regular veterinary check-ups is essential for managing this condition.

Syringomyelia (SM)

Syringomyelia is a severe neurological condition that is alarmingly common in Cavaliers. It involves the formation of cavities or cysts within the spinal cord near the brain. Dogs with SM may show signs of discomfort, such as sensitivity around the head and neck, whimpering, and scratching at the air. MRI scans are the most definitive way to diagnose this condition.

Hip Dysplasia

Hip Dysplasia, a malformation of the hip joint, is another concern for Cavalier King Charles Spaniels. This condition can lead to arthritis and mobility issues. Owners should watch for signs of discomfort during exercise or difficulty in standing up. Maintaining a healthy weight and regular exercise can help manage this condition.

Neurological Disorders (Syringomyelia)

Syringomyelia (SM) is a significant concern for the breed and a common cause of death. This neurological disorder is characterized by the formation of fluid-filled cavities in the spinal cord near the brain. It can cause severe pain and a range of neurological symptoms. Treatment options vary, but early detection and management can improve the quality of life for affected dogs.


Various forms of cancer also pose a significant threat to Cavaliers. Some of the most common types include lymphoma, mast cell tumors, and hemangiosarcoma. Cancer treatment may involve surgery, chemotherapy, or radiation, depending on the type and stage. Regular health screenings can aid in early detection, which is crucial for effective treatment.

Old Age-related Complications

Like many breeds, Cavaliers often pass away due to complications associated with old age. These may include organ failure, general body system deterioration, and decreased mobility leading to a lower quality of life. Providing a healthy diet, regular exercise, and ongoing veterinary care can help ensure that a Cavalier enjoys a full and healthy lifespan.
