Temperament & character

The Cavalier King Charles Spaniel is friendly, cuddly, and rarely aggressive toward people or other animals. He seeks constant closeness with his owner and generally gets along well with children. Wariness of strangers or pronounced territorial behavior is atypical for the breed.

Exercise & stimulation

Exercise needs are moderate; daily walks and play sessions in the garden are usually enough. As a descendant of spaniels, he still shows interest in scent games and light retrieving.

Grooming

The silky, medium-length coat tends to mat around the ears, legs, and tail and should be brushed several times a week. The floppy ears predispose the breed to ear infections, so regular checks are needed.

Suitable for beginners?

As an affectionate, easily led dog, the Cavalier is generally suitable for beginners. However, because of the breed's well-known heart problems, close, lifelong veterinary monitoring is important.

Health & common problems

The breed is strongly affected by mitral valve disease (MVD), which often appears by middle age and requires regular cardiac checkups. Syringomyelia related to the skull shape also occurs, as does patellar luxation.

Good with: Families, seniors, first-time owners
