The King Charles Spaniel is a small dog breed of the spaniel type. In 1903, The Kennel Club combined four separate toy spaniel breeds under this single title. The other varieties merged into this breed were the Blenheim, Ruby and Prince Charles Spaniels, each of which contributed one of the four coat colours now seen in the breed.

Questions people ask

Adult males usually weigh 3.6–6.4 kg and females 3.6–6.4 kg. Most are close to their full size by around 19 months, though the last little bit of filling out takes longer. Growth reference: Salt et al. 2017, WALTHAM (under 6.5 kg band).
No English Toy Spaniel cycle figures are published here yet, so this is general guidance rather than a breed number: most females have a first season somewhere between six and fifteen months, and cycles then settle to roughly every 180 days. Smaller breeds tend to start earlier and larger ones later.
10–12 y — the usual range. Uncited — a general reference figure, not a published one · no measured cohort for this breed. How the later years go comes down to weight, teeth, exercise and regular check-ups far more than to the breed.
