Clarification: The body should give a strong impression of thick-set squareness. The appearance of a short back is most desirable. Elbows should fit close to the body and should turn neither in nor out while the Pug is standing or moving. The topline should be level from withers to tail should be set high. The underline should continue the cobby appearance with no obvious tuck-up. A well ribbed-up Pug will have a broad chest with the sternum protruding forward of the front assembly; however, an abnormal projection of the breastbone (pigeon-breast) is undesirable. Moderate loose skin down the back is a matter of personal preference: the structure under the skin is the primary concern.
Undesirable: Low at the shoulders; roach or sway back; sloping croup; narrow chest; tuck-up; lean, rangey body; slabsides; pigeon breast; too fat or too soft; skin either too tight or overdone.
