Trying to teach "shy"

The goal is to grab his nose with his paws and keep them there. Silvia suggested doing it with him lying down first so his paws are both free. Well, it is slow going, but we are gaining. I get stuck sometimes with tricks. We never did get penguin going very well. He just doesn't understand he needs to STAY in sit up position.

This "shy" has progressed lately with both paws. He SO wants to do his karate chop, so that is hard to get rid of, but we are getting somewhere. Just not practicing much, so maybe if I start practicing more we will progress faster.
