Need help with city ordinance deeming dog vicious without a crime, solely based on breed

I have taken all the steps, I have contacted the mayor, spoken in front of the board of aldermen and taken sufficient evidence in. They only deem Rottweilers, Pit Bulls, and Dobermans. They removed German Shepherds although there is substantial evidence of more attacks from that breed than dobermans. There has got to be something someone can do to help
