Cavalier King Charles Spaniel
A small spaniel whose original job was simply to keep people company. Gentle and flat-friendly, but mitral valve disease runs through the breed, so a breeder's cardiac screening record is the first thing to ask about.

Weight and lifespan are reference ranges from the breed guide. They vary by sex, lineage and individual dog and do not predict your dog’s ideal weight or lifespan. Read the care descriptions alongside the individual dog’s history.
Background and characteristics
Cavaliers descend from the toy spaniels that sat in the laps of British nobility, and the modern breed was reconstructed in the early twentieth century to match the dogs shown in old portraits. Because companionship was the job rather than a side effect, these dogs are unusually open with strangers and easy with other dogs. The flip side is that they take being left alone badly; separation distress is one of the most common behavioural complaints in the breed, and a household that is empty from morning to evening is a poor fit no matter how nice the house is.
Exercise and play
Thirty to sixty minutes of walking a day, split in two, covers the exercise requirement. They are not an endurance breed, but enough spaniel remains that a squirrel or a bird can trigger a sudden bolt, so off-lead freedom in unfenced areas is a bad bet.
Coat and everyday care
The coat is silky and medium-length with feathering on the ears, legs and tail. Clipping is optional — most owners only tidy the feet — but brushing two or three times a week keeps mats from forming behind the ears and in the armpits, and shedding rises noticeably in spring and autumn.
Health considerations
Health should drive the decision more than anything else here. Mitral valve disease appears in Cavaliers earlier and more often than in almost any other breed, which is why the lifespan range starts as low as it does. Syringomyelia is also documented in the breed; persistent scratching at the neck or shoulder without contact, or yelping when picked up a certain way, warrants a proper neurological workup rather than reassurance.
In the UK, ask whether the breeder follows the Kennel Club and Cavalier club heart-testing protocols and get to see the certificates; in the US, be especially wary of volume sellers and online listings, and ask for cardiologist-issued results on both parents. Annual heart auscultation should be part of every routine check-up for the dog's whole life.
Home environment and care planning
Day to day this is an easy dog to live with in an apartment or a small house. It is not a nuisance barker and adapts to whatever the family is doing. The muzzle is short enough that hot, humid afternoons are best avoided, and any dog with a diagnosed heart murmur should be walked in the cool part of the day as a standing rule.
