Are all of your dogs intact (not spayed and neutered)?  If they are not spayed do you notice that the aggression occurs as a result of any of them being in season (estrus), or in the hormonally elevated times before or after estrus?  This would be sexual aggression.  If this is the case spaying will probably help.

If they are already spayed than the problem is probably due to territorial aggression.  It is important for you to monitor times when the problem occurs and try to anticipate when it will happen again.  Than you will have to intercede, by separation, or when it begins to occur by correction. The best correction is one that will get the pit bull's attention and stop the aggression immediately.  Rattling a can of pennies, blowing a whistle, spraying water in her face, or using a loud air horn, etc.    If these methods don't work, please consult your veterinarian, who may be able to give you some medication for your pit bull which will help to control the aggression, or you may have to consult with a professional dog trainer.
