Grooming is a regular part of their care.

Health and lifespan
Cavalier King Charles Spaniels typically live 12 to 15 years, with the senior stage beginning around age nine. This breed is prone to several health conditions that warrant regular veterinary attention. Heart disease is a significant concern and often develops earlier than in other dogs; specific conditions include mitral valve disease and congenital heart defects. Neurologic conditions such as syringomyelia can also affect quality of life. Other conditions seen in the breed include brachycephalic airway syndrome, patellar luxation, allergic dermatitis, progressive retinal atrophy, cataracts, and degenerative joint disease.
Regular veterinary exams, early screening, and close monitoring of behavior and comfort are especially important. Individual dogs may vary, and the conditions listed do not represent a comprehensive list of all health, genetic, or developmental conditions that may affect a Cavalier.
For a working household, the primary commitment is consistent veterinary care. Cavaliers do best in homes that provide companionship and a stable routine, and they have limited tolerance for being alone.

Challenges
The Cavalier King Charles Spaniel is a companion breed that thrives on closeness, and that closeness is where the practical challenges begin. These dogs have limited tolerance for being alone and prefer consistent companionship, which can be a strain for households where both partners work long hours away from home. Some individuals show mild separation anxiety when left alone too often, so consistent routines and regular companionship are important.
Health monitoring is a longer-term commitment. Heart disease is a significant concern in this breed and often develops earlier than in other dogs. Neurologic conditions such as syringomyelia can also affect quality of life. Regular veterinary exams and early screening are especially important. Other conditions to be aware of include mitral valve disease, patellar luxation, progressive retinal atrophy, and brachycephalic airway syndrome.
Grooming is moderate but consistent. The feathered areas on the ears, legs, and tail require extra attention to avoid matting, and regular brushing keeps the coat free of knots.

What to ask the rescue
Before bringing a Cavalier King Charles Spaniel home, ask the rescue about the dog's veterinary history, particularly any screening for heart conditions or neurologic issues. The breed is prone to mitral valve disease, congenital heart defects, and syringomyelia, so confirm whether echocardiograms or neurologic exams have been completed. Ask about the dog's current activity level and whether moderate daily walks and play sessions fit your schedule. Inquire about grooming needs: the medium-length, feathered coat requires regular brushing to prevent matting, especially on the ears, legs, and tail. Ask whether the dog has shown any signs of separation anxiety, since Cavaliers prefer close interaction with their family and have limited tolerance for being alone. Confirm the dog's comfort around children and other pets, as the breed is typically very social. Finally, ask what positive reinforcement training methods the rescue recommends, since Cavaliers respond well to gentle, consistent guidance.
