A pug is a massive dog with a square and powerful body. It has a fairly compact body, a straight back, a deep-set chest and a strong lumbar. The tail is tightly twisted into a ringlet (often double) and is worn on the side. The head is wide, massive, the muzzle is shortened. The outer part of the muzzle is covered with deep wrinkles that stretch from the inner corners of the eyes to the outer part of the muzzle. Wrinkles on the forehead resemble a diadem. The eyes are dark, bulging, a good look, the ears are small and thin, velvet to the touch, set high and wrinkled, when worn, their shape resembles rose petals.
Of great importance is how the pug moves, the dog must move in a characteristic rolling step. Such a step is characteristic only for dogs with the correct body structure, a flat top line and straight hind limbs, well set under the body. A firm step and throwing when running the front limbs high forward, reduces the show class of the pug.
The pug’s coat is short, thick and smooth. It is soft to the touch, if it is stiff and wavy, this is considered incorrect. The color is silver, tan, apricot or black. If the wool has a multi-colored color, then the mask, ears and the so-called diadem on the forehead should be black, forming a contrast with the main color. Pugs molt throughout the year, so they need to be combed frequently.
