A Cavalier King Charles Spaniel stands 12 to 13 in (30 to 33 cm) at the shoulder.
Height is measured at the withers, the top of the shoulders. The head and ears extend above that line. The American Kennel Club breed profile gives 12-13 inches. The listing describes an adult dog, not a growth chart for puppies.
Ranked by the tallest height its standard names (13 in), the Cavalier King Charles Spaniel is the joint 45th smallest of the 297 dog breeds on this site. See the smallest dog breeds ranked.
Drawn at the same 12 in: Drever, American Hairless Terrier and Border Terrier. Same drawing, different listings: a Cavalier King Charles Spaniel’s, a Drever’s, an American Hairless Terrier’s and a Border Terrier’s figures are each the lower end of its range.
This is a published species or breed reference, not a prediction for an individual animal. Where a range is supplied, both ends appear with the reading. Shoulder height and head height are kept apart when comparing animals.
All 30 toy dogs by height, tallest first, or every dog breed. To compare your own dog, measure it at the withers.
