The Shih Tzu is a sturdy little dog with a short muzzle and large dark brown eyes. They have a soft and long double coat. Although sometimes long, a Shih Tzu will not always have extremely lengthy hair like the Pekingese (but with short legs). Some of them have more short, curly hair. This is purely a choice made by the owners. A Shih Tzu should stand no more than 26.7 cm at the withers and with an ideal weight of 4.5 to 7.3 kg.
