Cavalier King Charles Spaniel: 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.

How much exercise does a Cavalier King Charles Spaniel need?

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.

Cavalier King Charles Spaniel: grooming & shedding

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.

Is the Cavalier King Charles Spaniel 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.

Cavalier King Charles Spaniel health 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.

The Cavalier King Charles Spaniel sheds moderately and is only conditionally suitable for allergy sufferers. What matters is a contact test of several hours before getting one — not the amount of coat. The trigger, Can f 1, sits in saliva and dander.
