I agree with the others. You don't have a MEAN Yorkie; you have a Yorkie puppy engaging in normal puppy behavior.

What you need to do is have toys/bones always close at hand in every room that puppy is allowed in. When puppy starts chewing on inappropriate objects (like people!), tell him no and substitute a toy or bone. You will have to do this millions of times but he'll eventually get it.

For harder bites, when it really hurts, either yelp loudly or yell "NO!" while breaking eye contact, turning around and walking away. Ignore pup for a minute or two and then start over. All is forgiven at this point (until he does it again). He needs to learn that hurting you = immediate loss of your attention.

Do NOT engage in play with Zoe that involves biting inappropriate objects and don't allow anyone else to, either! She can't understand that biting sometimes is okay and isn't okay at other times.
