Be sure to consider
craft's advice. We have (or I should say Mrs.
C has, a Bichon/Shih-Tzu cross (called a
Zuchon and I've neever seen a smarter dog nor one that requires the socialization that she needs (the dog, not Mrs.
C). The little dog wants only one thing from life... to be the center of the universe and (OK, two things) play incessantly..
We live on a cattle ranch in the western U.S. and have always had working dogs. Blue Heelers, primarily. They live in the barn and are only sociable enough to insist on riding in the back of the pick-up when headed out to check on things. So this took some getting used to for me.
This cross is an F1 between the Bichon and Shih-Tzu, meaning first generation. As such they are a great deal more genetically vigorous than either parent lineage. Be sure you are aware of the several potential health problems in the Bichon. Know your breeder and ask questions.
