(a) No owner of a dog, except a dog constantly confined to a registered kennel, shall fail to require the dog to wear, at all times, a valid tag issued in connection with a certificate of registration. A dog's failure at any time to wear a valid tag shall be prima facie evidence of a lack of registration and shall subject any dog found not wearing the tag to impoundment, sale or destruction.
(R.C. § 955.10)
(b) Whoever violates this section is guilty of a minor misdemeanor.
