Floppy 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 grey are frequently seen. For conformation showing, the coat must be left in its natural state, though trimming for neatness around the feet and anus is allowed. The shorter cut is typically called a 'puppy cut' or a 'teddy bear cut' when the puppy cut is accompanied by a fuller, rounder face, resembling a cute and cuddley stuffed animal. A number of health issues, some of them hereditary, have been found in individual Shih Tzu, and are listed below.
