The King Charles Spaniel typically weighs 4-8 kg, stands 23-28 cm, and lives 10-14 years.

Consider this breed if…

you want a gentle, affectionate lap dog with modest exercise needs,
someone is home most of the day - it bonds closely,
you can budget for heart and dental care over its life,
you can brush a silky coat and clean long ears regularly.

Do not consider this breed if…

the dog would be alone for long workdays,
you want an active dog for sport or long hikes,
you cannot commit to monitoring heart health as it ages,
you want a flat-faced breed without breathing or eye concerns.

Frequently asked questions

How much does a King Charles Spaniel cost?
Puppies from reputable breeders in the US commonly run $1,500-$3,000, and the breed is less common than the Cavalier so you may wait. The bigger concern is health: heart and dental issues can raise lifetime vet bills. Over a 10-14 year life, expect $12,000-$20,000 or more, and managing heart disease can add thousands.
Is a King Charles Spaniel the same as a Cavalier?
No. The King Charles Spaniel (English Toy Spaniel) is a separate, older breed - smaller, with a flatter face and a more domed head than the Cavalier King Charles Spaniel. They share ancestry but differ in build and are registered separately.
How much exercise does a King Charles Spaniel need?
Not much. Short daily walks plus indoor play are enough for this low-energy lap dog. Because of the flat face, avoid hard exercise in heat, since the breed can struggle to cool itself.
Are King Charles Spaniels healthy?
They are prone to some real issues, including heart disease such as mitral valve problems, plus dental disease and, in some, breathing or eye concerns from the flat face. Buy from breeders who screen, and budget for regular vet checks.
