The Pug's appearance is characterized by a flat, wrinkled face, compact body, and curled tail. Pugs have four color variations: fawn with a black mask and ears, entirely black, silver, or apricot. The silver or apricot-fawn colors should be decided so as to make the contrast complete between the color and the trace and the mask. The breed generally stands between 10 and 11 inches (25–28 cm) tall at the withers with an ideal weight range of 14 to 18 lb (6.3 to 8.1 kg). However, current AKC judges indicate slightly larger Pugs as higher quality. "Fawn" is the most common Pug color, black is rare, and silver which is an almost white coat with no black guard hairs. Silver is often confused with "smutty" which is undesirable and is characterized by a dark head and sometimes chest and forelegs. Most fawn Pugs have black facial masks.
