How old is she?? Has she had any training?? How old was she when she came to you?
When she bites you, let out a high pitched yelp, like her siblings would do. When she does not bite, praise her and offer a tug/chew toy for her to sink her teeth into. Basically, until she has learned that no teeth on skin are ever acceptable, you need to always have an appropriate item in your hand/on your person for her to bite on.
Another reason I won't have a puppy - to be honest, I don't have the patience for teething and non-stop puppy energy! Youngest I'll go is 6-8 months
