Michigan’s dog vaccination laws require every dog four months of age or older to be currently vaccinated against rabies by an accredited veterinarian, and you cannot obtain the county dog license Michigan also requires without showing proof of that vaccination. The two obligations are locked together under the Dog Law of 1919, so complying with one is how you comply with the other.
Who Must Vaccinate and When
Under MCL 287.266, any dog four months or older must be currently vaccinated against rabies by an accredited veterinarian using a vaccine licensed by the United States Department of Agriculture.1Michigan Legislature. MCL – Section 287.266 – Dog Law of 1919 (Excerpt) The vaccination certificate must state the month and year the vaccination expires, based on the veterinarian’s professional judgment. In practice, the initial dose is valid for one year and boosters are valid for three years afterward, but the expiration date printed on the certificate controls.
Rabies is the only vaccination Michigan law requires. Veterinarians commonly recommend other vaccines, and boarding facilities and groomers often require them, but those are not legal mandates.
How Licensing Ties to Vaccination
Michigan ties licensing directly to vaccination. When you apply for a dog license through your county treasurer or an authorized agent, you have to bring a valid rabies vaccination certificate.1Michigan Legislature. MCL – Section 287.266 – Dog Law of 1919 (Excerpt) No certificate, no license.
Each county board of commissioners sets its own licensing deadlines. Some counties require licenses by March 1, others by June 1, and some tie the deadline to the expiration month of the dog’s rabies vaccination. Fees vary widely too. In Kalamazoo County for 2026, a spayed or neutered dog costs $16 to license, while an unaltered dog over one year costs $46.2Kalamazoo County. 2026 Dog Licenses Officially on Sale In Kent County, a one-year license runs $17 for a spayed or neutered dog and $26 for an intact dog, with discounts for seniors 62 and older.3Kent County, MI.

Late penalties add up quickly. Otsego County charges a flat $30 late fee. Muskegon County adds $5 for the first month late plus $10 for each additional month.5Otsego County, MI. Dog Licenses Check your own county’s rules before the deadline hits.
The license tag has to stay on the dog’s collar at all times.
What Happens If You Don’t Comply
An unlicensed dog is treated as a public nuisance under Michigan law. Under MCL 287.277, the county treasurer is required to identify unlicensed dogs and forward the owners’ names to the county prosecuting attorney, who then initiates proceedings against those owners.6Michigan Legislature. MCL – Section 287.277 – Dog Law of 1919 (Excerpt) Because vaccination is a prerequisite for licensing, failing to vaccinate makes it impossible to comply with the licensing requirement, exposing you on both fronts at once.
The financial exposure gets much worse if an unvaccinated dog bites a person or another animal. The dog will likely be quarantined at the owner’s expense, and the owner is on the hook for civil liability under Michigan’s dog bite statute (below). Quarantine, veterinary observation, and legal proceedings can cost far more than a vaccination and license ever would.
Medical Exemptions Are Limited
Michigan does not have a clearly codified statutory exemption for dogs whose health conditions make rabies vaccination dangerous. A former provision, MCL 287.266a, was repealed in 1970. In practice, veterinarians may decline to vaccinate a dog with a serious medical condition and document that decision in writing. If your dog is in that situation, work with both your veterinarian and your county treasurer’s office to figure out whether a license can still be issued without a current vaccination certificate.
Michigan statute does not create a vaccination exemption for dogs used in research or educational programs.
Service Dogs Are Not Exempt
Service dogs must be vaccinated and licensed the same as any other dog. The U.S. Department of Justice has said the Americans with Disabilities Act does not override local animal control or public health laws, so a vaccination and licensing requirement applies equally to service animals.7U.S. Department of Justice. Frequently Asked Questions About Service Animals and the ADA Some counties waive the licensing fee for service dogs, but the vaccination itself is still mandatory.
Why the Vaccine Matters Beyond the Ticket
Michigan is a strict liability state for dog bites. Under MCL 287.351, if a dog bites a person without provocation while that person is on public property or lawfully on private property, the owner is liable for damages regardless of whether the dog has ever shown aggression before. A person is lawfully on private property if they are performing a duty imposed by state or federal law, or if they are an invitee or licensee of whoever lawfully possesses the property. Someone who entered for an unlawful purpose does not qualify.8Michigan Legislature. Michigan Compiled Laws Section 287.351 – Person Bitten by Dog; Liability of Owner
After a bite, the CDC’s standard protocol is a 10-day confinement and observation period, even for a dog with a current rabies vaccination. Veterinarians should not administer a rabies vaccine during that window, because adverse vaccine reactions could be confused with clinical signs of rabies. If the dog shows signs of illness during those 10 days, the local health department must be notified immediately.9Centers for Disease Control and Prevention. Information for Veterinarians – Rabies
Michigan’s Public Health Code gives the Michigan Department of Health and Human Services authority to establish procedures for controlling rabies, including rules for the disposition of potentially rabid animals.10Michigan Legislature. MCL – Section 333.5111 Local health departments coordinate with animal control and veterinarians to handle bite reports and decide whether the person bitten needs post-exposure treatment. A current, well-documented vaccination is your strongest defense against the worst-case version of that process.
What Compliance Actually Costs
A standard rabies vaccine typically runs between $35 and $75, depending on the veterinarian and location. Add a routine exam fee of $50 to $150, and first-year vaccination costs land in the $85 to $225 range. After that, you’re looking at a booster every three years plus your county’s annual license fee. Even at the high end, staying compliant costs a fraction of what an unvaccinated, unlicensed dog can cost you after a single bite or an animal control pickup.
