Weighing between 13-18 pounds with a silky coat in colors like Blenheim (chestnut and white) or tricolor (black, white, and tan), Cavaliers are known for their large, expressive eyes and floppy ears 4. Their sociable and playful nature makes them ideal family pets, excelling as therapy dogs and companions for children and the elderly alike 6. However, their popularity has come at a cost.
A 2021 study revealed that Cavaliers carry more harmful genetic mutations than other breeds, particularly those linked to mitral valve disease (MMVD), a degenerative heart condition affecting nearly all Cavaliers by age 10 2. This, combined with syringomyelia—a painful spinal disorder affecting up to 70% of six-year-old dogs—has led countries like Norway to ban their breeding due to ethical concerns .

Despite these issues, responsible ownership can mitigate risks. Regular veterinary check-ups, a balanced diet, and daily exercise (30-60 minutes) are crucial 9. Grooming requires daily brushing to maintain their coat and weekly ear cleaning to prevent infections 7. Owners must also monitor weight to avoid exacerbating joint problems like hip dysplasia 4.
A poignant example of the breed’s resilience is "Billy," a Cavalier rescued from Gaza after 18 months in captivity. Found emaciated but alive, Billy’s return highlighted the breed’s adaptability and the deep bond between humans and dogs 1. However, such stories underscore the need for stricter breeding regulations to ensure Cavaliers’ health aligns with their royal legacy.
In conclusion, while the Cavalier King Charles Spaniel captivates hearts with its grace and loyalty, addressing its genetic vulnerabilities remains essential to safeguarding its future.
