General Appearance
A decidedly square and cobby dog. The pug should be 'multum in parvo" (a large amount in a small space), but this condensation should be shown by compactness of form, well-knit proportions, and hardness of developed muscle.

Head And Skull
Head large, massive, round; not apple-headed, with no indentation of the skull. Muzzle short, blunt, square but not up faced. Wrinkles large and very deep.

Eyes
Dark in colour, very large, bold and prominent, globular in shape, soft and solicitous in expression, very lustrous, and when excited, full of fire.

Ears
Thin, small, soft, like black velvet. There are two kinds: the 'rose' and the "button". Preference should be given to the latter. (Button ears are close, compact ears which fold over in front.)

Forequarters
Legs very strong, straight, of moderate length, and well under the body.

Body
Short and cobby, wide in chest and well ribbed.

Hindquarters
Legs very strong, straight, of moderate length, and well under.

Feet
Neither so long as the foot of the hare, nor so round as that of the cat; well split-up toes; the nails should be black.

Tail
(Twist). Curled as tightly as possible over the hip. The double curl is perfection.

Coat
Fine, smooth, soft, short and glossy, neither hard nor woolly.

Colour
Silver, apricot fawn or black. Each should be clearly decided, to make the contrast complete between the colour, the trace and the mask. Markings clearly defined. The muzzle or mask, ears, moles on cheeks, thumb mark or diamond on forehead. The back-trace should be as black as possible. Mask: the mask should be black, the more intense and well defined, the better. Trace: a black line extending from the occiput to the twist.

Weight And Size
Desirable weight from 14 to 18 ids (for a dog or a bitch).

Faults
Lean, leggy. Short legs and long body.
