On the trading for treats thing - Not a Yorkie but I once had a poodle that would always get whatever we didn't want her to have in order to get a treat. Her favorite was coins. She'd come up to you with a coin in her mouth - sticking out so you could see it. If you ignored her, she would get closer and closer to "show" you the coin. Eventually she would climb up on you and stick the coin out right in your face. If you tried to take it from her without a trade, she would take your hand off. She was a crazy dog - I loved her but she's the reason that I started formal training with my dogs - she was a little out of control!
