Symmetry and general appearance are decidedly square and cobby. A lean, leggy Pug and a dog with short legs and a long body are equally objectionable.
Head: The head is large, massive, round - not apple-headed, with no indentation of the skull. The eyesare dark in color, very large, bold and prominent, globular in shape, soft and solicitous in expression, very lustrous, and, when excited, full of fire. The ears are thin, small, soft, like black velvet. There are two kinds - the "rose" and the "button." Preference is given to the latter. The wrinkles are large and deep. The muzzle is short, blunt, square, but not upfaced. Bite - A Pug's bite should be very slightly undershot.
Neck, Topline, Body: The neck is slightly arched. It is strong, thick, and with enough length to carry the head proudly. The short back is level from the withers to the high tail set. The body is short and cobby, wide in chest and well ribbed up. The tail is curled as tightly as possible over the hip. The double curl is perfection.
Forequarters: The legs are very strong, straight, of moderate length, and are set well under. The elbows should be directly under the withers when viewed from the side. The shoulders are moderately laid back. The pasterns are strong, neither steep nor down. The feet are neither so long as the foot of the hare, nor so round as that of the cat; well split-up toes, and the nails black. Dewclaws are generally removed.
The coat is fine, smooth, soft, short and glossy, neither hard nor woolly.
Hindquarters: The strong, powerful hindquarters have moderate bend of stifle and short hocks perpendicular to the ground. The legs are parallel when viewed from behind. The hindquarters are in balance with the forequarters. The thighs and buttocks are full and muscular. Feet as in front.
