hello, your baby is really cute!
i do know of a superstar yorkie. i met the doggie and her daddy last weekend.
she does commercials/print ads/tv stuff (and she travels around the world with her daddy to perform)
the main thing actually though is training. they want yorkies that can follow directions. so that the photo shoot can be done as quickly as possible.
so the doggie needs to listen really well, and hold still and stuff like that. but yea. you should definitely work with your baby if you are interested.
the superstar yorkie i met was actually adopted from shelter. she can do tricks and play poker as well LOL (oh and she can push a cart)
