My bichon came in third in a class of three. I never took our yorkie. He really listens very well. But the class I had the other in was just about walking on a leash and taking commands. Sit. Stay. Things like that.
They are very good now. (sheesh it's been a couple years)
Just remember to be consistent. One word commands. Praise when good *treats* It's difficult if there are more than one alpha giving commands tho. Good Luck. and Have fun.
