Mich. Comp. Laws § 287.270
For the purposes of this act, a kennel shall be construed as an establishment wherein or whereon 3 or more dogs are confined and kept for sale, boarding, breeding or training purposes, for remuneration, and a kennel facility shall be so constructed as to prevent the public or stray dogs from obtaining entrance thereto and gaining contact with dogs lodged in the kennel. Any person who keeps or operates a kennel may, in lieu of individual license required under this act, apply to the county treasurer for a kennel license entitling him to keep or operate a kennel. Proof of vaccination of dogs against rabies shall not be required with the application. The license shall be issued by the county treasurer on a form prepared and supplied by the director of the department of agriculture, and shall entitle the licensee to keep any number of dogs 6 months old or over not at any time exceeding a certain number to be specified in the license. The fee to be paid for a kennel license shall be $10.00 for 10 dogs or less, and $25.00 for more than 10 dogs. A fee of double the original license fee shall be charged for each previously licensed kennel, whose kennel license is applied for after June 1. With each kennel license the county treasurer shall issue a number of metal tags equal to the number of dogs authorized to be kept in the kennel. All the tags shall bear the name of the county issuing it, the number of the kennel license, and shall be readily distinguishable from the individual license tags for the same year.
The county treasurer or county animal control officer shall not issue a kennel license for a new kennel under the provisions of this act unless the applicant furnishes an inspection certificate signed by the director of the department of agriculture, or his authorized representative, stating that the kennel to be covered by the license complies with the reasonable sanitary requirements of the department of agriculture, and that the dogs therein are properly fed and protected from exposure commensurate with the breed of the dog. The director of the department of agriculture shall promulgate reasonable rules with respect to the inspections in the manner prescribed by law. The inspection shall be made not more than 30 days before filing the application for license. The provisions of this act shall not be effective in the counties of this state that are operating under the provisions of section 16 wherein the board of supervisors have appointed a county animal control officer with certain powers and duties, unless the counties by a resolution duly adopted by the board of supervisors accept the provisions of this act.
