It is natural for puppies to bite. They don't have hands or fingers, so they explore their world with their mouths. A puppy's mother and siblings can help teach him not to bite. For that reason, puppies shouldn't be taken from their mother too early. If a puppy has already left his mother, you can help teach him not to bite yourself.
When playing with your puppy, if he gets too rough and nips or bites too hard, give out a shrill "YIP!" or "OUCH!". Even if it doesn't, pretend your puppy's bite really hurt and stop playing with him for a short time. Puppies are smart and learn quickly that the fun and games stop if he puts his mouth on you.
Then be careful not to encourage rough-housing with your pup. He needs to get very clear signals about what behavior is and isn't appropriate. Look for games to play with your pup that don't encourage wild, wacky, biting behavior.
If it is play biting, then try lightly spraying it with water from a spray bottle every time it bites. If it is an aggressive bite then it would really depend on if and why the dog is biting other dogs, stranger's, the owner etc..
they wont unless you tell them its bad(best done when a puppy)

All dogs bark at strangers, there alerting you that there is someone there, soft scolding should stop it but they do it for your safety.
Take your dog to your local groomer and ask them to give her/him a puppy cut. They should know what it is. You can also look online at pictures of yorkie puppy cuts and bring them a picture of what you are looking for.
Unfortunately, hounds in general tend to be chewers - ask anyone with a basset in particular. It tends to be a lifelong trait. As for biting you in particular, they ought to grow out of it. Scolding it IMMEDIATELY when it has nipped you with a firm "No!" is often effective. There is absolutely no need to punish such behaviour in a puppy by tugging/pulling on its lips, biting back, shouting or hitting - all this will do is teach the puppy to become defensive and possibly scared, which ultimately may make the biting worse.
yes it is
The puppy will stop bitting at around 2 years old. Although it may never stop if you continue to allow it to do so :)
My yorkie bites me every single day.
