The Shih Tzu is a small, sturdy dog with a body that is slightly longer than it is tall. The head is round and broad, and wide between the eyes. The square muzzle is short, with an inch or less from the tip of the nose to the defined stop. The nose is broad, with well-open nostrils. Nose, lips and eye rims are liver on liver colored dogs, blue on blue dogs and black on all other colors. The teeth meet in a level or under bite. The large, round eyes are dark in color, but lighter on blue and liver dogs. The large, pendant, low-set ears hang down and are covered in abundant hair. The back is level. The muscular legs are straight and well-boned. The high-set tail is carried over the back and is covered in abundant hair. Dewclaws are sometimes removed. The double coat is dense and long, flowing down over the dog. The hair above the eyes is often tied in a topknot. There is a profuse beard and mustache and the hair on the muzzle is short. Coat comes in all colors.
