For the most part it is typical puppy behavior. When puppy starts nipping just let out a little yelp. They will learn they are hurting you and will stop. I do this when Duchess gets a little too rough when we are playing but it's my fault too. I have a bad habit of playing with Duchess with my hands like fake boxing and wrestling on the floor (which she loves highly recommended. get down on the floor and play with them, they love it.) and she tries to grab my hands with her mouth and will nip me occasionally. We get to playing and chasing each other and she will accidentally bite down. Most of the time her mouth is open like she is going to nip me but she doesn't do it except every now and then she will bite if she is really worked up.

As for running away, in her mind it's play time. No worries, you have a typically adorable yorkie puppy.
