ps...as far as teaching - you need GREAT eye contact and a yorkie that really REALLY likes to hear you laugh
What I did was show her MY smile and said to her - let me see YOUR smile - then I gently touched the corners of her mouth and in 2 days she was doing it on her own - Now ....if I ask to see her 'smile' - she smiles just like that picture
I tried it with Cheri and she just looked at me like I was nuts and wanted a treat
