13. The owner of a potentially dangerous dog who is found by clear and convincing evidence to have violated this act, or any rule or regulation adopted pursuant thereto, or to have failed to comply with a court's order shall be subject to a fine of not more than $1,000 per day of the violation, and each day's continuance of the violation shall constitute a separate and distinct violation. The municipal court shall have jurisdiction to enforce this section. An animal control officer is authorized to seize and impound any potentially dangerous dog whose owner fails to comply with the provisions of P.L.1989, c.307 (C.4:19-17 et seq.), or any rule or regulation adopted pursuant thereto, or a court's order. The municipal court may order that the dog so seized and impounded be destroyed in an expeditious and humane manner.
