The best thing is you got her at 8 weeks old and not sooner, from about 4-5 weeks old pups start to play with each other, they learn mouthing inhibition from each other and they start to learn that when one bites to hard the one will "yip" in a HIGH pitch tone, like it is mortally wounded, then will leave the game for a short time. If puppy A wants to play with puppy B then they need to back off their bite. If they are biting you when you pet them then the next time you pet them get a toy and shove it in their mouth to redirect the teeth, then PRAISE them for chewing on it.. If you are grabbing at them or pushing them away some will think it's just your form of play. What needs to be done is you need to "YIP" in a high tone and stop all play, after about 20 seconds go back but with a toy to redirect them, and praise them for playing with it. Never rough house using your hands and feet, they don't understand and play can escalate quickly and your flesh will suffer.
They need to understand that biting makes play stop so keep teeth off flesh and we will play. This will not keep them from biting and playing with another dog, the other dog will tell them if they are too rough, but it does help with continuing to teach them about mouthing inhibition.
