Temperament

Cavaliers are extremely affectionate, gentle and easy-going. They get on with children, older people and other pets, and dislike being left alone.

Daily exercise

45–60 minutes of walks and play a day. Their hunting instinct may make them chase birds in open areas.

Feeding

Prone to weight gain, and extra weight strains the heart.

Example: a neutered adult Cavalier King Charles Spaniel at an ideal weight of 7 kg (15 lb) needs roughly 480 kcal a day (RER × 1.6). Work out your own pet's needs with the calorie calculator and check ideal weight with the ideal weight calculator.

Common health problems

  • Mitral valve disease (MMVD): very common and early-onset; heart listened to every year
  • Syringomyelia (SM): skull–spinal cord problem; neck pain, air scratching
  • Eye disease
  • Patellar luxation
  • Ear infections
🚨Not every Cavalier King Charles Spaniel will have these problems; the list shows conditions seen more often in the breed. If you notice symptoms, or are getting a puppy or kitten, ask about the parents' health screening and plan regular check-ups with your vet.

Care tips

  • Always have the heart checked at the yearly visit
  • Brush 2–3 times a week, check ears
  • Count resting breaths: over 30 per minute at rest means call the vet
  • Keep an ideal weight
🪪Microchip your pet and keep your contact details up to date — in many countries it is required by law.
