Cavalier King Charles Spaniel

Small; 13–18 lbsModerate9–14 years lifespan

Who this breed is NOT for

Anyone gone long hours (they need company), or anyone unwilling to research a breeder's health testing and budget for possible heart care. Sweet temperament, real medical risks.

Bred to do

Companion and lapdog with a spaniel heritage — bred to be gentle, affectionate company for people.

Exercise needs

Moderate — daily walks and play. Adaptable: happy to hike or to cuddle, but they should not become couch potatoes.

Temperament

Gentle, affectionate, eager to please, sociable with everyone. One of the sweetest, most easygoing temperaments in dogdom. They bond closely and dislike being alone.

Trainability

High — soft, willing, and food-motivated. A good first-time breed temperamentally.

With kids & pets

Excellent with both — patient, friendly, rarely aggressive. A genuine family dog.

Living situation

Great for apartments or houses; adaptable. The main need is company — they struggle when left alone for long hours.

Grooming & shedding

Silky medium coat that needs regular brushing; moderate shedding. Keep ears and feathering clean.

Health & costs

This is the honest hard part. The breed has a high incidence of serious inherited conditions — mitral valve heart disease (very common, often early) and syringomyelia (a painful neurological condition), plus eye and ear issues. Vet costs can be significant. Buy ONLY from a breeder who does cardiac and other health screening; this matters more here than in almost any breed.

Best fit

People wanting a gentle, affectionate, adaptable companion who are home often and can commit to health-conscious sourcing and potential vet costs.

A note from Kerri

Temperament-wise, Cavaliers are as lovely as dogs get — I adore them. But I'd be failing you not to be blunt about the heart and neurological issues in this breed. If you want one, the single most important decision is the breeder: demand health-tested parents, and go in prepared for the possibility of cardiac care.
