When is she biting and growling? If its during play time be stern and tell her no and then ignore her for a little bit- they hate that. Consistency is the key; don't let her get away with it even once.

For the food I think ProPlan is probably average to high for quality. You want to make sure theres meat and vegetables all for the first several ingredients but corn is not good. Theres probably other people who can tell you better about the food choices, also sometimes you can find sites online to help rate your food.

For the ear flopping, its a little late, but you still might be able to stand it up. Make sure to trim the hair so there isn't any extra weight on it and then put some tape around it to force it to stand up (may want to use a triangle piece of cardboard to help). Check and retape every few days until hopefully it stands up. But if not don't be too upset. Good luck with your baby!
