(a) Each person complying with the provisions of § 22-338, 22-339 or 22-342 shall receive from the town clerk a license on a form prescribed by the commissioner, which license shall contain a description of the dog and the number under which such dog is licensed. The town clerk shall issue to such person a tag or plate of material prescribed by the commissioner, upon which shall be distinctly marked the name of the town in which such dog is licensed, the license number and the year of license. No town clerk shall issue such license or tag to any person for any neutered male or spayed female dog not previously licensed as such unless the person causing the dog to be licensed exhibits to the town clerk a certificate from a licensed veterinarian stating that such veterinarian has neutered or spayed the dog or that, after examining the dog, he finds that the dog has been neutered or spayed.

(b) The town clerk shall provide for the issuance and renewal through the mail of licenses issued under sections 22-338 and 22-339. The town clerk may make applications for such licenses available at such facilities as kennels, pet stores, veterinarian offices, humane society offices and pet grooming establishments.
