A. 
In all cases it shall be the duty of the duly appointed Dog Officer to investigate any violation under this chapter either witnessed by the Dog Officer or reported to the Dog Officer in a written complaint by any citizen of the Town. The Dog Officer shall provide the dog owner with a written copy of the complaint and investigation report not more than three days after the conclusion of the investigation but, in any event, not more than 30 days after receiving the complaint.
B. 
If, after the Dog Officer's investigation of an alleged violation under this chapter, such officer has reason to believe that the described violation did in fact occur as set forth in said written complaint or as witnessed by the Dog Officer, it shall be the Dog Officer's duty to issue the owner, in writing, the appropriate order and/or to impose the appropriate fine, designed to prevent a recurrence or continuation of such violation. The period of time during which the order shall be in effect shall be on the order. If the complainant and the owner involved are in agreement with the order so issued, then the matter respecting that particular violation under this chapter shall be considered resolved.
