In counties having a population of eighty thousand or more inhabitants and cities of the first class contained in such counties, if upon final hearing the defendant is adjudged guilty of any violation of section 54-601 or 54-608, the court may, in addition to the penalty provided in section 54-613, order such disposition of the offending dog as may seem reasonable and proper. Disposition includes sterilization, seizure, permanent assignment of the dog to a court-approved animal shelter or animal rescue as such terms are defined in section 28-1018, or destruction of the dog in an expeditious and humane manner. Reasonable costs for such disposition are the responsibility of the defendant.
