Nothing could be further from the truth, however. Shih Tzus are beautiful, but they are also friendly, lively, devoted companions.
One unique characteristic of the Shih Tzu is their undershot bite. Their lower jaw is slightly wider than the upper, and the upper teeth bite inside the lower teeth, rather than outside, when their mouth is closed.
Legends regarding the Shih Tzu abound. One says that Buddha traveled with a little dog fitting the description of a Shih Tzu.
