The Shih Tzu is a small, sturdy little dog with a short muzzle and large dark eyes. With a soft and long double coat, it stands no more than 26.7 cm (101â„2 in.) at the withers and with an ideal weight of 4.5 to 7.3 kg (10 to 16 lbs). Drop ears are covered with long fur, and the heavily furred tail is carried curled over the back. The coat may be of any color, though white and with blazes of white are frequently seen. The Shih Tzu is slightly longer than tall, and bigger dogs ideally should carry themselves "with distinctly arrogant carriage". A very noticeable feature is the under-bite, which is required in the breed standard.[1] The traditional long silky coat, which reaches the floor, requires daily brushing to avoid tangles. Because of their long coat and fast-growing hair, regular grooming is necessary, which may be costly and should be considered when looking forward to having this dog breed. Often the coat is clipped short to simplify care. For conformation showing, the coat must be left in its natural state, though trimming for neatness around the feet and anus is allowed.[2]
