Coat
Medium length; short, thick, weather- resistant undercoat with a coarser, longer outer coat. Over-all length varies, with slightly thicker and longer ruff around the neck, chest and on the shoulders. The body coat lies flat. Hair is slightly longer on back of forelegs and underparts and somewhat fuller and longer on rear of hindquarters. The coat is preferably straight, but some waviness is permitted. This breed has a shedding coat, and seasonal lack of undercoat should not be too severely penalized, providing the hair is glossy, healthy and well groomed. A wiry, tightly marcelled coat is very faulty, as is an overly short, smooth and thin coat. Very Serious Fault--Fluffies--a coat of extreme length with exaggerated feathering on ears, chest, legs and feet, underparts and hindquarters. Trimming such a coat does not make it any more acceptable. The Corgi should be shown in its natural condition, with no trimming permitted except to tidy the feet, and, if desired, remove the whiskers.
Color
The outer coat is to be of self colors in red, sable, fawn, black and tan with or without white markings. White is acceptable on legs, chest, neck (either in part or as a collar), muzzle, underparts and as a narrow blaze on head. Very Serious Faults: Whitelies--Body color white, with red or dark markings. Bluies--Colored portions of the coat have a distinct bluish or smoky cast. This coloring is associated with extremely light or blue eyes, liver or gray eye rims, nose and lip pigment. Mismarks--Self colors with any area of white on the back between withers and tail, on sides between elbows and back of hindquarters, or on ears. Black with white markings and no tan present.
