You've got a dominance issue on your hands, Arnie. And probably a teething issue, too! Does puppy have plenty of things to chew on to alleviate the irritation of growing the adult teeth?
When puppy is chewing on you, at the first bite, give a sharp, loud, "No!!" and walk away, ending the "game" that puppy is playing. Do not allow her to follow, and if you have to, separate her from yourselves. Are you crate training? Whatever you do, do NOT use her crate, (if you're going that route) as a punishment.
Also, reinforce your dominanace over her by making her roll onto her back in your arms and submit to you messing with her belly, throat and feet. If she resists this, reinforce her by grabbing her scruff, gently, and forcing her to submit. Yes, it sounds harsh, but it's not. Puppy is learning where she falls in the heirarchy of her new "pack" and you need to get that message across to her clearly: that she is Omega dog and everyone else in the house ranks above her. Calm, assertive leadership!!
