OMG. Was she picked up as a stray or an owner surrender? If the shelter has any way of knowing who owned her, I would assume animal cruelty charges are going to be pressed. I agree with publicising this. Sometimes a neighbor or accquaintance comes forward to report the owner.

Is she going to be rehabilitated and adopted? If I were you, I would contact a boxer rescue, and see if they will come get her. Does your shelter work with rescues? If you need help finding a rescue, I will be happy to help you. I have done a lot of work with breed rescues over the years.
