Lifted from Wikipedia:  A Shih Tzu (play /ˈʃts/ sheet-soo; Mandarin: [ʂɨ́tsɨ]) is a breed of dog weighing 4–7.25 kilograms (8.8–16.0 lb) with long silky hair. The breed originated in China, and is the closest known descendant of the prehistoric Chinese wolf, the "Senji". Shih Tzu were officially recognized by the American Kennel Club in 1969. The name is both singular and plural. 

I have been fortunate to have taken care of a male and female shih tzu, and in this page, I will try to impart the lessons I have learned from the experience.
