Sweet, gentle and adaptable — the ultimate affectionate companion.

Ratings describe typical dogs of the breed on a 1–5 scale. Individual dogs vary with lines, upbringing and training.

Temperament

Cavaliers are friendly with everyone — family, strangers, children and other animals. They love laps and company and adapt their energy to their owners, happy to walk for miles or snooze on the sofa.

They are sensitive and do not cope well with isolation or harsh handling. Most retain some spaniel instinct and will chase birds or squirrels, so recall needs work.

Living with a Cavalier King Charles Spaniel

Exercise

About 30–60 minutes of walks and play daily. Adaptable to apartments and active homes alike.

Grooming

Brush several times a week, especially the ear and leg feathering. Clean ears regularly. Moderate shedding.

Training

Eager to please and responsive to gentle, reward-based training. Work on recall early.

Kids & other pets

Excellent with children, seniors and other pets, including cats. Their gentleness makes them a common choice for first-time and multi-pet homes.

Time alone

Companion dogs through and through; prone to separation distress if left for long hours.

Home fit

Adapts well to apartments and smaller homes when daily needs are met.

Health

With good breeding and care, a Cavalier King Charles Spaniel typically lives 12–15 years. These are the conditions most associated with the breed — not a prediction for any individual dog.

  • Mitral valve disease (MVD)

    Affects nearly all Cavaliers by age ten, often much earlier. Choose breeders who follow the MVD breeding protocol with annual cardiologist exams.

  • Syringomyelia and Chiari-like malformation

    Fluid-filled cavities in the spinal cord causing pain; MRI screening of breeding dogs reduces risk.

  • Episodic falling and dry eye / curly coat syndrome

    Inherited conditions with DNA tests.

  • Patellar luxation

    Loose kneecaps are common in toy breeds.

  • Hip dysplasia

    Occurs more than many expect in a small breed.

Ask a breeder for

  • Annual cardiac examination by a cardiologist
  • MRI screening for syringomyelia
  • Hip, patella and eye evaluation
  • DNA tests: episodic falling and dry eye / curly coat

History

Toy spaniels were favourites of the English court; King Charles II was famously devoted to them. Over time these dogs were bred with flatter faces, becoming the English Toy Spaniel.

In the 1920s American Roswell Eldridge offered prize money for spaniels resembling those in old paintings, with longer muzzles. Breeders responded, and the Cavalier was recognised by the Kennel Club in 1945 and the AKC in 1995.

Did you know?

  • The Blenheim colour is named after Blenheim Palace, home of the Dukes of Marlborough.
  • A legend says Charles II decreed that toy spaniels could enter any public building.
  • Many Blenheims have a thumbprint-shaped “Blenheim spot” on the head.
