Ash, it is YOUR decision, but I found 2 more specialists in the state, who may be able to help:
Cranberry Townshib:
Lap Wolf Dog Training--owner Heather Houlahan
[email protected]
742-772-7837

and in Port Matilda (10 minutes from here)
Bell Hollow Dog Training Center
[email protected]
814-692-7241

I know these both say they are training centers, but both said they will take aggressive dogs--it could be worth an email.
