I don't know anything personally about the s**tzu .... however, we have a Westie in our family! My son-in-law bought Jackson for my daughter for her birthday a couple of years ago. He was a cute,intelligent, wild little pup but I have noticed the last couple of times I have seen him that he has really calmed down a lot! He is great with the children and
very energetic! I believe that he has matured a lot ... he is very loving and
sturdy!! I honestly think that you could carry him around all day by his tail & he wouldn't mind .... he always has a great big smile on his face.

That's about all I know about the breed .... sorry! Good luck ... let us know which you choose.
