If you are considering a Shih Tzu, I would strongly caution you to be sure and study, study, study!!! Shih Tzu can come plagued with a multitude of problems if not bred properly. Do your homework and get your hands on as much as you can. Study the breed standard, www.shihtzukisses.com/standard.htm
Many people come to me looking for a Shih Tzu, do not even know the way a proper Shih Tzu is supposed to look. Look at photos of people who show their dogs and compare the Shih Tzu you are thinking of purchasing with those. www.shihtzukisses.com is photo rich. Check it out
Be sure to read the true story of someone who did not do her homework and ended up getting more than she bargained for. See her story at www.shihtzukisses.com/bamboozled.htm
Remember "All puppies are cute" What are they going to look like when they grow up.
