What activity can my Yorkie participate in?

I would like for my Yorkie to participate in an activity that she would enjoy. Although, she is 4 lbs. doesn't like running, can't pull anything heavy, is afraid of water, likes people (I have considered therapy), is very smart, and isn't much of a digger. Like I said, I have considered therapy but I was hoping for more of a sport kind of thing. She is a beautiful dog, but not perfect to her standard so conformation is not quite the option.
