The word "pug" may have come from the Old English pugg or "puge", which were affectionate terms for a playful little devil or monkey. Pug puppies are often called puglets.

                   

While most Pugs appearing in eighteenth century prints tended to be long and lean,the current breed standards call for a square, cobby body, a compact form, deep chest, and well-developed muscle.Their heads, carried on arched necks, should be substantial and round, the better to accentuate their large, bulging, dark eyes. The wrinkles on their foreheads should be distinct and deep, The ears should be smooth and soft, like black velvet and come in two varieties: "rose" (small, round and folded with the front edge angled toward the mask, giving the head a more rotund shape) and "button" (level with the top of forehead and folded at a sharp ninety degree angle). Breeding preference goes to "button" Pugs.The lower teeth should protrude farther than their upper, meeting in an under-bite.
