(a) The town clerk of any town may deputize employees of any dog pound in such town as agents for the issuance of dog licenses and tags, provided the town clerk shall be solely responsible for compliance with the provisions of the statutes relating to the duties of the town clerk in connection with such licenses and tags and the moneys received therefor.

(b) Any person acquiring an unlicensed dog from a dog pound shall be issued a temporary license by the town clerk, or his agent deputized pursuant to subsection (a) of this section, which shall expire thirty days after the issuance thereof. Prior to the expiration of a temporary license, the person holding the license shall apply for a license for the remainder of the license year, pay the appropriate license fee specified in § 22-338, and submit a certificate signed by a veterinarian, or a copy thereof, stating (1) that the dog has been vaccinated against rabies, (2) the date of the vaccination and (3) the duration of the immunity provided by the vaccine. No license shall be issued unless the certificate indicates that the immunity provided by the vaccine is effective at the time of licensing.
