It is unlawful for any person to abandon or turn out at large any animal whether sick, diseased, disabled or otherwise. Animals, when rendered worthless by reason of sickness or other disability, shall be disposed of by the owner thereof as provided in Section 6.08.050 for the disposition of dead animals within the city. If after following a reasonable investigation a responsible owner cannot be identified, it shall be the duty of the animal control officer of the city to dispose of any animals found running at large within the city which are worthless from sickness, disease or other disability.
