§ 391.06 Dangerous Dogs, Requirements.
   Subd. 1.   Requirements. For any dog declared dangerous by operation of this section, state statute, court order, an ordinance or regulation from another jurisdiction, or by operation of a declaration by an Animal Control Authority, the owner, in addition to complying with all the registration requirements set forth under subsection 391.05, shall keep and maintain the dog pursuant to all requirements of this section.
   Subd. 2.   Restraint. An owner of a dangerous dog shall keep the dog, while on the owner’s property, in a proper enclosure as defined by subsection 391.02, Subd. 7. The dog shall, at all times, be kept in such proper enclosure unless the dog is, at any and all times the dog is outside a proper enclosure, muzzled and restrained by a substantial chain or leash not to exceed six feet in length and under the physical restraint of a responsible person 18 years of age or older. The muzzle, chain, and leash must all be of such a design, manufacture, and maintained in a condition that will prevent the dog from biting any person or animal, but that will not cause injury to the dog or interfere with its vision or respiration.
   Subd. 3.   Dog Sterilized. The owner of a dangerous dog shall have the dog sterilized within 30 days after the owner has received a notice of dangerous dog.
   Subd. 4.   Leased Premises. A person who owns a dangerous or potentially dangerous dog and who rents property from another where the dog will reside shall disclose to the property owner prior to when the dog begins to reside on the property, or prior to entering the lease agreement, and at the time of any lease renewal, that the person owns a dangerous dog that will reside at the property.
   Subd. 5.   Tag. A dangerous dog registered under this section shall have a standardized, easily identifiable tag identifying the dog as dangerous and containing the uniform dangerous dog symbol affixed to the dog’s collar at all times.
   Subd. 6.   Property Inspection. The owner of a dangerous dog shall permit the Animal Control Authority to enter the property where a dangerous dog is kept or located, at all hours reasonable under the circumstances to inspect to ensure compliance with the provisions of this section, applicable state statutes, order from a hearing officer, or directive from the Animal Control Authority. The failure of an owner to permit such inspection is, by itself, a ground to immediately seize the dog pursuant to subsection 391.10 and revoke the dangerous dog registration pursuant to subsection 391.05, Subd. 7.
   Subd. 7.   Review. If, in reviewing the conditions for keeping a dangerous dog there have been no ordinance violations for a period of two years, the Animal Control Authority or impartial hearing officer may use discretion in determining whether the conditions set forth above are still required.
