Shih Tzu's are great little dogs. I've had a lot of fun with Shih Tzu puppies. If the one you are getting is only 6 weeks old, you will most likely have no problems with his temperment. I know how loving your home is and the only problem Shih Tzu's I have seen have come from rough living situations. A lot of Shih Tzu's can be yappy little things but it just comes down to the individual dog. If the puppy is showing no signs of behavioral problems, most likely none will ever arise since I'm sure your mom will bring him up in the best possible home with the most love.

Good luck with your new house. Its not too far from your mom and Cassie I hope. I was thinking of you and Graham today because there are a couple of dogs at the shelter who remind me of him (one has only three legs ).
