How long have you had her? she is only 7 weeks old? I would be surprised if at this age she had stopped biting to be honest, you want a pup to be a biter because you can teach them not to bite and they learn control, usually at 7 weeks they are still with their litter mates and learn some bit inhibition through play fighting with their litter mates, as she is young you need to take their place, I normally use the yelp training, ie if the pup bites down I yelp and pull my hand to me with a hurt expression on my face and say NO I do not shout, I do not slap I just give a sharp yelp, if the pup was with its littermates, they would yelp if another pup was biting too hard, it will take a good few more weeks for your pup to get out of this and you need to be consistant and fair in your training, as mentioned she is still very young, try not to expect too much too soon.
