Growing up eons ago, my mom had three miniature poodles over time. Every one was smart as hell. They didn't bark at every little thing, but they didn't get caught off guard either. They don't shed, since they have fur instead of hair. Not much more I can say about 'em, and I don't know if that holds true for the toys.
Edit:
- Except Shi-Tzu's, I've never met a mean Shi-Tzu...
Holy crap, let me introduce you to my
sister-in-law's dog! I want to kill that little sh!t-zu :| She snaps at everybody including family members. God, I hate that dog and I can't believe they even keep it. Funny thing is, her offspring are great. Don't know WTF happened to her!
