With such kennel or cattery license, there shall be issued a number of appropriate metal tags equal to the number of dogs or cats authorized to be kept in the kennel or cattery. Such tags shall be made in a form so that they may be readily distinguishable from the individual dog registry license tags required for the same year. The licensee of a kennel or cattery shall at all times keep one of such tags attached to the collar of each dog or cat over six (6) months old kept by him under such license. Such tags may be transferred from one dog or cat to another in the kennel or cattery whenever any dog or cat is removed. (1965 Code § 9-7-59)
