You answered your own question. She needs correction. At this point the correction is going to be physical. I am NOT advocating abuse at all. Firm, physical correction. E-collars can be a great tool if used properly. Correction straight from "mom" is best however. There is a huge difference in being an animal lover and doing what is best for the dog and society. Some dogs need more correction than others, If she is biting "mom", how long til she bites someone else, possibly a child? "Mom" also has to be dominant. Lead the pup, do not let her lead. Make her wait for commands to do everything like eat, go out the door, get in the car, etc. My dog will stare at his dish forever until I tell him okay." Then he will eat.
I own a hunting dog with a very strong prey drive. He is a handful and tests his limits every day. You have to be the alpha dog full time. It is hard work and no one in the family can slack off.
