It is unlawful for any person to use any identification tag for any other dog than for the one for which it was originally issued. The owner of a licensed dog shall preserve the license upon the premises wherein the registered dog is kept and shall, upon demand of the animal care services manager, or any health officer, or a police officer of the city, show to such animal care officer, health officer, or police officer the license to keep such dog. (Ord. 2007-018 § 7; prior code § 6.03.036)
