The Municipal Court shall declare a dog to be potentially dangerous if it finds by clear and convincing evidence that the dog caused bodily injury as defined by N.J.S.A. 2C:11-1(a) to a person during an unprovoked attack and poses a serious threat of bodily injury; severely injured or killed another domestic animal and poses a threat of serious bodily injury to a person or poses a threat of death to another domestic animal; or has been trained, tormented, badgered, baited, or encouraged to engage in unprovoked attacks upon persons or domestic animals. A dog shall not be declared potentially dangerous if having caused bodily injury as a result of being provoked or severely injuring or killing a domestic animal if the domestic animal was the aggressor. The municipality shall bear the burden of proof to demonstrate that the dog was not provoked.
