  EvilSoma, you don't say how old your Yorkie is, but what you describe sounds like VERY normal puppy behavior.  Please understand that puppies are teething and they NEED to chew.
 When your puppy bites you, give him something appropirate to chew on.  When he bites you hard enough to hurt, yelp or say "Uh Uh" loudly.  Break eye contact and move away from him.  As soon as he stops trying to bite, all is forgiven; start over.  In this manner, besides teaching him not to bite, you teach him "bite inhibition".  (Here is what that means.  All dogs when sufficiently stressed will bite.  It is a fact of life.  Dogs who have been taught "bite inhibition" know that there are varying levels of biting - some less severe than others).
 
 The jury is still out on playing tug-of-war.  Some trainers say "no, never".  Some say it is fine.  Use your judgement depending on YOUR dog.
