Cavalier vs Cocker Spaniel

Both are silky-coated spaniels with long feathered ears, so they get mixed up often. This page compares the Cavalier King Charles Spaniel with the American Cocker Spaniel, the one called simply Cocker Spaniel in the US. The English Cocker is a different breed with its own size and proportions.

The Cavalier is a companion dog of 12 to 18 pounds, while the Cocker is a gun dog of about 22 to 28 pounds. Health risks differ: Cavaliers are known for early heart disease and syringomyelia, and Cockers for eye problems, ear infections and epilepsy. Grooming is the other gap, since a Cocker's longer, thicker coat calls for daily brushing.

How this works

The quiz uses what you can see or look up: weight, ear set, coat color, height and registration group. Each answer points to Cavalier or Cocker Spaniel, and the cue line under each question explains how strong that clue is. Weight and ear set carry the most weight, and registration papers settle it.

This page covers the Cavalier King Charles Spaniel and the American Cocker Spaniel. English Cockers, King Charles Spaniels and crosses such as cavachons or cockapoos can give mixed results. For a pedigree answer, ask the owner or breeder for papers.
