Because of the potential risk of injury to the your dogs and the humans that live with them, I urge the both of you to seek assistance from a trainer/behavior consultant. Go to APDT.com, there you can find someone close to you that may be able to do in-house consults. Be prepared to do a lot of training. Aggression really isn't something that advice on the internet can help.

I wish the both of you the best of luck

E-mail me if you have any questions.
