I am constantly amazed at all the color combinations that are produced by the Shih Tzu. No two are ever the same! That is one of the things I like so much about this breed!
To determine what color a Shih Tzu is you must start with the nose.
The dilute colors Liver and Blue cannot have a black nose. Regardless of coat color, a Liver colored nose indicates a Liver Shih Tzu, and a blue nose indicates a Blue Shih Tzu. The colors of Liver and Blue can vary from light to dark.
