The City may establish a dog pound and keep therein dogs seized under any of the provisions of this article. Any dog for which the head tax is delinquent, or any dog found running at large in the City, may be seized and impounded. The owner or keeper of any impounded dog may have such dog upon paying the delinquent tax, if any, thereon and the impounding fees. If not paid, such dog may be sold and there shall be deducted from the proceeds of such sale the delinquent tax, if any, and the impounding fees, and the residue, if any, shall be paid over to the owner of such dog. If such dog is not sold, it may be killed and its body disposed of by the City without liability to the owner.
