Oh, and I have a one-year-old yorkie/shih-tzu mix that I just love (just because you mentioned both
)...see her pics in the gallery, her name is Ruby... I got her from a high-school aged girl who foolishly bought a puppy withought considering her own life changes and schedule (school all day, then she got an after-school job)... regardless of what you ultimately choose, be sure to do a lot of research before hand...good luck
