If your dog barks, he better be licensed!!

Michigan Law:

287.277 Identification and location of unlicensed dogs; public nuisance; list; commencement of proceedings; duties of sheriff; nonfeasance in office.

Sec. 17. The county treasurer may, based on records of the dogs actually licensed in each city or township of the county and any report under section 16, identify and locate all unlicensed dogs. If a dog is required to be licensed under this act but is unlicensed, the dog is a public nuisance. The county treasurer shall immediately list all unlicensed dogs identified by this section and shall deliver copies of the list to the prosecuting attorney of the county and to the director of the department of agriculture. On receiving from the county treasurer the name of any owner of an unlicensed dog, the prosecuting attorney shall at once commence the necessary proceedings against the owner of the dog, as required by this act. The sheriff shall locate and kill, or cause to be killed, all such unlicensed dogs. Failure, refusal, or neglect on the part of a sheriff to carry out the provisions of this section constitutes nonfeasance in office.
