Q. Is it possible to show a Cocker Spaniel that is black with a white muzzle, stripe between eyes, on chest, and front toes?
A. The American Kennel Club breed standard allows black Cockers to have a small amount of white on the chest and/or throat. White in any other location is a disqualification.
Parti-color Cockers are defined as dogs of two or more solid, well-broken colors, one of which must be white. “Primary color which is ninety percent (90%) or more shall disqualify,” per the AKC breed standard.
Therefore, your Cocker would be ineligible to compete in the conformation ring as either a black or a parti-color.
