Under Michigan dog bite laws, the owner is strictly liable when their dog bites someone who was lawfully on public or private property and did not provoke the animal. That means a victim does not have to prove the owner was careless or knew the dog was dangerous. The bite itself, plus lawful presence and no provocation, is the case. Victims have three years to sue, and the owner is on the hook for the full range of damages that follow.
The Strict Liability Rule
MCL 287.351 sets a low bar for victims and a high one for owners. The statute makes the owner liable for “any damages” when a dog bites a person, so long as two conditions are met: the victim was lawfully on public or private property, and the victim did not provoke the dog. The dog’s history does not matter. An owner cannot defeat the claim by showing the dog had never bitten anyone, had never growled, or had passed every temperament test its breed offers.1Michigan Legislature. Michigan Code 287.351 – Person Bitten by Dog, Liability of Owner
“Lawfully present” has a specific meaning in the statute. You qualify if you were on the property to perform a duty required by state or federal law, which includes postal carriers and other government workers. You also qualify if you were an invited guest or someone the occupant otherwise permitted to be there. The one carve-out: a person who entered to commit an unlawful or criminal act is not lawfully present, even if they were invited in the first place.1Michigan Legislature. Michigan Code 287.351 – Person Bitten by Dog, Liability of Owner
One boundary worth knowing up front: the statute covers bites. If a dog knocks someone down, jumps on them, or causes injury without biting, strict liability does not apply. The victim in that situation would have to bring an ordinary negligence claim and prove the owner failed to use reasonable care.
What Victims Can Recover
Because the statute makes the owner liable for “any damages suffered,” Michigan courts read that broadly. Recoverable losses generally sort into two buckets.
Economic damages are the measurable financial hit. Emergency room bills, surgery, antibiotics, physical therapy, ambulance costs, lost wages, damaged clothing or personal property. If a bite leaves scarring that will need future revisions or ongoing treatment, projected future costs count too.
Non-economic damages compensate for harm without a receipt: pain and suffering, emotional distress, disfigurement, loss of enjoyment of life, physical impairment. In cases involving children or facial scarring, non-economic damages often outrun the medical bills by a wide margin.
Suits are filed in the circuit court where the bite happened. The victim still has to prove the bite occurred and that they were lawfully present, but because negligence is out of the picture, the burden is far lighter than in most personal injury cases.
How Long You Have to Sue
Michigan gives dog bite victims three years from the date of the injury to file suit. The same three-year window applies whether the claim is brought under MCL 287.351 or as an ordinary negligence action.2Michigan Legislature. Michigan Code 600.5805 – Statute of Limitations
Three years sounds long. It isn’t, in practice. Serious bites can require a year or more of treatment before the full extent of the injury is clear, and building a case takes time: documenting injuries, gathering witness accounts, and, in scarring cases, retaining medical experts. Filing near the deadline also hands the defense arguments about stale evidence and fading memories.
What the Owner Can Argue Back
Strict liability is not absolute. The statute builds in two defenses, and one more comes from case law.
Trespassing
If the person bitten was not lawfully on the property, the statute does not apply. That includes someone who entered to commit a crime, even if the occupant had let them in for another reason.1Michigan Legislature. Michigan Code 287.351 – Person Bitten by Dog, Liability of Owner
Provocation
The statute conditions liability on the bite occurring “without provocation.” Courts have had to work out whether accidental conduct can qualify. In Bradacs v. Jiacobone, the victim accidentally fell onto a dog. The trial court told the jury that even unintentional acts could be provocation. The Michigan Court of Appeals reversed, finding that the accidental contact was not enough.3Justia. Stephanie Bradacs v James Jiacobone
Practically, provocation usually means a deliberate act directed at the dog: hitting, kicking, cornering, or aggressive teasing. Being near the dog or making a startling movement is unlikely to count.
Assumption of Risk
Some professionals who handle dogs for a living may be found to have assumed the risk of being bitten. Veterinarians and their staff are the clearest example, and the same reasoning can extend to groomers, kennel workers, and trainers who voluntarily handle animals they know may be unpredictable.
When Criminal Charges Are Possible
A bite does not automatically produce criminal charges. Criminal exposure runs through a separate statute, the Dangerous Animals Act at MCL 287.321 through 287.323, not the civil strict liability rule.
When a Dog Is “Dangerous”
Under MCL 287.321, a “dangerous animal” is a dog that bites or attacks a person, or one that attacks and seriously injures or kills another dog while the other dog is on its owner’s property or under its owner’s control. A dog is not dangerous under the statute if the person bitten was trespassing, was provoking or tormenting it, or if the dog was defending someone from an assault.4Michigan Legislature. Michigan Code 287.321 – Definitions
Destruction Hearings
When someone files a sworn complaint that a dog is dangerous, a district court or magistrate issues a summons requiring the owner to appear and show cause why the dog should not be destroyed. After the hearing, the court must order the dog euthanized at the owner’s expense if it caused serious injury or death to a person or another dog. Even without serious injury, the court can order destruction if it finds the dog is likely to cause serious harm in the future or has already been declared dangerous.5Michigan State Bar. Michigan Court of Appeals Opinion – MCL 287.322
MCL 287.286a offers a parallel route: after a hearing on a complaint that a dog has bitten someone, destroyed property, shown vicious habits, or habitually trespassed, a court can order it killed or permanently confined to the owner’s premises, with costs charged to the owner.6Michigan State Bar. Michigan Court of Appeals Opinion – MCL 287.286a
Penalties for the Owner
Under MCL 287.323, the severity tracks the harm. If a dangerous dog kills someone, the owner faces involuntary manslaughter charges. If a dangerous dog causes serious injury short of death, the owner faces a felony. If an owner who had reason to know their dog was dangerous allows it to bite someone without causing serious injury, the charge is a misdemeanor.
Rabies Quarantine After a Bite
After any bite, the dog has to be confined for rabies observation for at least ten days. Confinement must be in an escape-proof structure, not a chain in the yard or a fenced area. Animal control can approve home confinement and may make unannounced checks during the observation period. If the dog dies for any reason during quarantine, the remains have to be sent to the Michigan Department of Health and Human Services for rabies testing.
The quarantine is not optional, and interfering with it exposes the owner to further legal trouble. For the victim, the outcome matters medically: signs of rabies in the dog mean post-exposure prophylaxis, which is expensive and adds to the damages picture.
Insurance and Breed Exclusions
Most homeowner’s and renter’s policies include liability coverage that reaches dog bite claims. That coverage typically pays the victim’s medical costs, the owner’s defense costs, and any settlement or judgment up to the policy limit. A serious bite that involves surgery and permanent scarring can easily produce a six-figure claim, so coverage is not a theoretical concern.
The catch is breed exclusions. Insurers routinely refuse to cover breeds they associate with higher bite risk, including pit bulls, Rottweilers, German shepherds, chow chows, Doberman pinschers, Akitas, mastiffs, and wolf-dog hybrids. The list varies by carrier. Some specialty insurers write standalone animal liability policies for excluded breeds, though premiums run higher.
An owner who finds out after a bite that the breed was excluded gets the worst of both outcomes: full personal liability for the victim’s damages, and no coverage to pay it.
Local Breed-Specific Ordinances
Michigan does not preempt local governments from passing breed-specific rules, and more than 30 municipalities have. These ordinances run from special permits, muzzle requirements, and stronger containment obligations to outright bans on ownership within city limits.7Michigan Humane. Bully Breeds and Breed-Specific Legislation
The most commonly targeted breeds are American Pit Bull Terriers, American Staffordshire Terriers, Staffordshire Bull Terriers, and Rottweilers, though some ordinances also sweep in Doberman Pinschers, Cane Corsos, and Chow Chows. “Pit bull” is a general label rather than a single breed, which makes enforcement uneven. Violating a local breed ordinance can also weaken an owner’s position in a civil bite case by showing they were already outside the law when the bite occurred.
Health Insurance Liens on Settlements
A settlement is not always what the victim keeps. If a health insurer paid for the bite treatment, it may have a legal right to recover that money from the settlement. This is subrogation, and it is standard in employer-sponsored plans governed by federal ERISA rules. The insurer places a lien on the settlement funds and gets repaid before the victim sees the remainder.
Medicare beneficiaries face a parallel rule. Medicare is a secondary payer by law, so when a third party is responsible for the injury, Medicare has a right to recover what it paid. The claim has to be reported to the Benefits Coordination and Recovery Center so Medicare can calculate its recovery amount.8Centers for Medicare and Medicaid Services. Reporting a Case
Ignoring these liens creates real problems. An attorney who distributes settlement money without satisfying a valid lien can be personally liable, and a victim who spends money Medicare is entitled to recover can end up owing funds they no longer have. Negotiating lien amounts down is routine work in personal injury practice and often materially changes what the victim actually takes home.
