 Historically the Cavalier King Charles Spaniel was a lap dog and is small for a spaniel, with fully grown adults comparable in size to adolescents of other larger spaniel breeds. Breed standards state that height of a Cavalier should be between 12 to 13 inches (30 to 33 cm) with a proportionate weight between 10 to 18 pounds (4.5 to 8.2 kg). The tail is usually not docked, and the Cavalier should have a silky coat of moderate length. Standards state that it should be free from curl, although a slight wave is allowed. Feathering can grow on their ears, feet, legs and tail in adulthood. Standards require this be kept long, with the feathering on the feet a particularly important aspect of the breed's features.
