Have your vet check her thyroid. An unbalanced thyroid can cause aggression issues.

Aggression
by: Deborah

The first question I would like to ask is the female fixed?
Female Jacks are unpredictable I own 2 boys and both of my boys are super dogs and no aggression at all I have never owned a female but they do say that they can change sometimes for the good or the bad it sounds like you may be need a trainer to help you with this issue..
Good Luck
