Puppy love is the best love with a lot of responsibilities. Training your dog an early age is very important. Keep your eyes on your puppy and know when specifically your puppy is biting. Your puppy has alot of energy and needs to release this energy with little games. Make sure to have a lot of toys for biting around your puppy.
Try to teach dog obedience commands, keep sessions very short. Dog obedience training games help you to keep busy mentally and physically. keep your puppy busy all the time so she will not have time to think about biting anymore. She might be just teething, you may want to ask your vet if your puppy has physical problem that she is trying to tell.
I think it might be just teething and having toys around will help a lot at this early age.
Let me know how it goes :)
