While on the property of its owner, an animal found to be a dangerous dog shall be confined indoors or in a securely enclosed and locked structure of sufficient height and design to prevent its escape or direct contact with or entry by minors, adults, or other animals. The structure shall be designed to provide the animal with shelter from the elements of nature. When off its owner's property, an animal found to be a dangerous dog shall be kept on a leash and muzzled in such a manner as not to cause injury to the animal or interfere with the animal's vision or respiration, but so as to prevent it from biting a person or another animal.
