Any person who keeps or operates a kennel, may, in lieu of the license for each dog required by this chapter, obtain licenses under a kennel certificate. Upon information supplied by such person, the Commissioner shall prepare a certificate describing the premises where the kennel is located and the actual number of dogs, three months or older, which are to be kept within the kennel. Such certificates shall be issued by the Commissioner upon payment of a fee of $25. With each kennel certificate the Commissioner shall issue a number of metallic tags equal to the number of dogs to be kept in the kennel. All such tags shall bear the number of kennel certificate and shall be readily distinguishable from the individual license tags for the same year.
