Question: do shih tzu change colors?
Answer: A good rule of thumb when choosing a Shih Tzu puppy is never to base your decision on color. That's because the breed is well known for changing coat colors as he enters adulthood. ... Fading: If a Shih Tzu carries the "G" gene, his coat will fade as he gets older. You will notice fading in puppies as young as a month old.
