 Just say NO!
Not to be rude but.......Just say NO! Stop playing or rough teasing w/your fingers & hands in any way. You are teaching and in essence "Training" your Puppy to bite and it can and will get worse as they get older. Apparently alot of people don't realize how serious this problem is. NO Dog Yorkie or any other Breed should be allowed to "Play" like that, just remember to you it's playing but for them it's "Reality" it's a behaviour that should NOT be Tolerated. If you do it correctly you can STOP him or her immediately. All it takes is consistency. It sounds like your Puppy has alot of pent up Energy?
You should try "Walking" them a few times daily to drain them. Believe me, you would be surprised at how much that helps. Yorkies need to be constantly stimulated mentally & physically. Claim your Fingers back!
Yorkies especially as Puppies are very cute it's very hard to be serious all the time about their "Training" since they are so irresistable. Good Luck!
