No you're right Ben it wouldn't be fair to her to have to sneak her in and out and break the rules there. If you want to keep her you're only option may be to move. If not, then perhaps a pitbull rescue can help with checking her for temperment issues and rehoming her. It's awful that as much as she might have been loved they allowed her to fight, so that's no love at all really. Poor dog. She sounds very loving in nature so I hope you can come to a good resolution with her needing a home either with you or some other responsible person.
