Some more information on the specifics of her behavior would probably help pinpoint the type of aggression your girl is displaying. As there are different methods for dealing with those types. You would probably already know if she had fearful tendencies, but maybe not, as fear aggression may not seem fearful at all. If she is displaying fear aggression, I would advise against the strong corrections, as that would only escalate her behavior.

Others are definately better qualified than me to give you advice on how to deal with this, but keep in mind the methods for dealing with this should be specific to the cause.
