What Happens If Your Dog Bites Someone in Michigan: Owner Liability, Legal Duties, and What’s at Stake
April 26, 2026
A dog bite can happen in seconds — a startled pet, an unexpected guest, a moment of poor timing — and suddenly you’re facing a situation with real legal weight. If your dog has bitten someone in Michigan, the consequences can reach far beyond a simple apology or a trip to urgent care.
Michigan is one of the strictest states in the country when it comes to dog bite liability. Michigan’s strict liability rule means an owner can’t escape liability by claiming they didn’t know their dog was dangerous, or by pointing out that they took reasonable precautions to protect people from their pet. That applies whether your dog has a spotless history or not.
This guide walks you through exactly what happens after a dog bite in Michigan — from the law that governs liability, to what your dog’s future looks like, to the financial and criminal exposure you may be facing. Understanding these rules clearly is the first step to handling the situation responsibly.
Important Note: This article is for general informational purposes only and does not constitute legal advice. If your dog has bitten someone, consult a qualified Michigan attorney to understand how the law applies to your specific situation.
Michigan’s Liability Standard: Strict Liability vs. the One-Bite Rule
In some states, a dog and its owner get a “free bite,” which releases the owner from liability if the dog has never bitten anyone before. However, Michigan dog bite laws fall under the heading of “strict liability,” meaning the owner is responsible when a dog bites and injures another person — even if it’s the first time the dog has ever bitten.
Under MCL 287.351, liability follows ownership, not the animal’s history. The core of the law is straightforward: “If a dog bites a person, without provocation while the person is on public property, or lawfully on private property, including the property of the owner of the dog, the owner of the dog shall be liable for any damages suffered by the person bitten, regardless of the former viciousness of the dog or the owner’s knowledge of such viciousness.”
The strict liability standard means that the dog’s history of behavior is irrelevant; the fact that the dog bit someone is enough to hold the owner responsible for damages, which can include medical expenses, lost wages, and pain and suffering. This is a meaningful distinction from negligence-based systems, where a victim must prove you did something wrong.
It’s also worth knowing what strict liability does not cover. The statute only addresses injuries caused by a dog bite. It does not apply to injuries caused by scratches, other physical contact, or injuries incurred while trying to protect oneself or escape a dog attack. For those situations, a victim may still pursue a negligence claim, but the strict liability statute itself won’t apply.
The Two Defenses Available to You
Owners who get sued under Michigan’s strict liability dog-bite statute can raise two defenses: if a dog bites someone because it was provoked, then the owner won’t be held strictly liable for medical bills and other damages stemming from the incident.
- Provocation: If the victim provoked the dog, the owner may be relieved of liability. Provocation includes actions like teasing, hitting, or otherwise antagonizing the dog in a way that would reasonably cause it to bite. Keep in mind that provocation usually requires intentional conduct that would reasonably cause a dog to bite, such as hitting, kicking, or severely tormenting the animal. Normal movements, petting, or playing are rarely enough.
- Trespassing: If a dog bites a trespasser — someone who wasn’t invited onto private property and has no legal reason to be there — then strict liability doesn’t apply. However, people making deliveries for the U.S. Postal Service or other companies (UPS, Amazon, FedEx, etc.), or those performing duties imposed by the laws of the state, as well as licensees of the property owner or individuals the owner has invited onto the property, also have a lawful right to be there — meaning they are protected under the statute.
Michigan’s approach to dog bites is notably stricter than many other states. Michigan has some of the strictest dog bite laws in the country. While some states require an injury victim to show the dog owner was negligent in restraining or controlling their dog, and other states give a break to owners whose dog has never acted out violently before, Michigan imposes statutory liability on dog owners for bites regardless of the dog’s past behavior or the owner’s conduct.

Your Immediate Legal Obligations After Your Dog Bites Someone in Michigan
The hours immediately following a dog bite are critical. What you do — and don’t do — in this window can significantly affect the legal and financial outcome of the situation.
Report the Bite
Under the Michigan Public Health Code, every bite must be reported to the local health department, typically within 24 hours. Owners, physicians, and veterinarians share this duty. Reporting initiates a rabies quarantine (usually ten days) and creates the official record victims need for insurance or litigation.
Michigan doctors are not required by law to report dog bite injuries to the police. However, they must report the bite to the public health agencies where the victim lives and where the bite occurred, if the two locations are different. The purpose of reporting dog bite cases to health agencies is to assess victims for rabies exposure.
Steps to Take Right Away
- Ensure the victim gets medical care. Make sure the victim receives prompt medical care. This is both the right thing to do and important for managing the legal record of the incident.
- Exchange insurance information. Exchange contact and homeowners or renters insurance information. Notify your carrier before speaking with the victim’s lawyer or posting on social media.
- Secure your dog. Confine your pet to prevent any further incidents. This also demonstrates responsible ownership to animal control and any investigating authorities.
- Document everything. Photograph the scene, note the circumstances of the bite, and collect witness contact information while details are fresh.
- Contact an attorney. What happens in the first few hours after a bite can determine whether the matter ends with an insurance payout or spirals into fines, criminal charges, or even euthanasia orders.
Pro Tip: Do not make statements admitting fault or speculating about what caused the bite before speaking with an attorney and your insurance carrier. Anything you say can be used in a subsequent civil or criminal proceeding.
It’s also worth knowing that once the victim is treated, they should file a dog bite claim with the police. The dog owner’s insurance company may balk at paying the claim if this step is neglected, even if there are serious injuries. In addition, if the victim plans on filing a dog bite lawsuit later, it’s crucial that a dog bite claim be in place. Understanding this process from both sides helps you anticipate what’s coming.
What Happens to Your Dog After a Bite in Michigan
One of the most pressing concerns for dog owners is what will happen to their pet. The answer depends heavily on the severity of the bite, your dog’s history, and how local authorities respond.
Quarantine
In most cases, your dog will be required to undergo a quarantine period following the bite. A dog may have to be quarantined for a certain time period after an attack is reported. This quarantine — typically ten days — is primarily a public health measure to monitor for signs of rabies. It may be served at home or at a veterinary or animal control facility, depending on local rules.
Euthanasia Orders
Owners are not typically required to euthanize a dog after an attack, unless a court decides it meets the legal definition of a “dangerous animal.” If so, a court may order the owner to euthanize a dog to prevent it from causing future harm.
Courts may order euthanasia when a dog causes death, maims a victim, or violates prior confinement orders. Owners receive notice and can contest the ruling, present vet testimony, or propose rehabilitation plans. This means you do have an opportunity to advocate for your dog’s life through the legal process.
Key Insight: Filing a civil insurance claim or lawsuit does not automatically trigger a euthanasia order. This decision falls under local animal control authorities, who consider the severity of the incident and the dog’s history.
In many cases, an owner may be allowed to keep the dog provided specific steps are taken to ensure the animal is no longer dangerous. These steps may include secure confinement, mandatory training, or muzzling requirements — all of which are addressed in more detail in the next section. If you’re interested in understanding more about responsible dog care practices, that knowledge can also support your case as a conscientious owner.
Dangerous Dog Designation and What It Means for You in Michigan
Beyond the immediate aftermath of a bite, Michigan law has a formal process for classifying dogs as “dangerous.” This designation carries lasting consequences for both you and your pet.
How a Dog Gets Designated as Dangerous
Animal-control officers may petition the district court to label a dog “dangerous” after a bite or aggressive attack. A quick hearing follows, and judges can order confinement, secure fencing, liability insurance, microchipping, or mandatory muzzling during walks.
Repeat incidents or serious injuries can escalate the designation to “vicious,” bringing steeper restrictions. The distinction matters: a “dangerous” designation brings significant obligations, but a “vicious” label can lead to more severe legal consequences, including potential euthanasia orders.
Michigan statutes 287.321 through 287.323 concern attacks by dogs and other dangerous animals. These statutes define a dangerous animal as one that attacks or bites a person or another dog — so long as that dog is on the property or under the control of its owner.
What the Designation Requires of You
| Requirement | Details |
|---|---|
| Secure Confinement | Fenced enclosure or locked structure that prevents the dog from escaping or people from entering |
| Microchipping & Registration | The dog must be tattooed and registered with the Michigan Department of Agriculture at your expense |
| Muzzling | Required during walks or any time outside secure confinement in many jurisdictions |
| Liability Insurance | Some courts and municipalities require owners of designated dangerous dogs to carry specific liability coverage |
| Signage | Cities such as Detroit, Warren, and Sterling Heights impose additional mandates — secure fencing, “Beware of Dog” signage, and microchipping for animals already deemed dangerous. |
Failing to comply with these requirements after a dangerous dog designation is not just a regulatory violation — it becomes powerful evidence against you if your dog bites again. Once a dog has been found dangerous by a court, the owner can be charged with a misdemeanor for a future bite that causes minor injuries to a person. The stakes escalate sharply from there.
It’s worth noting that a dangerous dog does not include an animal that attacks or bites a trespasser, a dog that bites a person who torments or provokes the animal, or a dog that responds as per its instinct when it senses danger from someone. These exceptions parallel the civil liability defenses discussed earlier.
Insurance Coverage and Financial Liability in Michigan
For most dog owners in Michigan, the financial fallout of a bite will flow through their insurance policy — but it’s important to understand exactly what that covers, what it doesn’t, and what happens if coverage falls short.
How Homeowners and Renters Insurance Works
Homeowner’s, renter’s, or umbrella policies typically cover dog attacks even when they happen off the insured property. This is an important point: if your dog bites someone at a park or a neighbor’s home, your policy may still respond.
Typical policies cover between $100,000 and $300,000, which can help pay for medical expenses (surgeries, rabies shots, physical therapy), lost wages if the victim was unable to work, and pain and suffering, including emotional distress and PTSD.
If a lawsuit is filed against you because of the attack, the homeowners’ insurance will supply you with a lawyer to defend the case. This means you don’t pay the lawyers yourself. Instead, the insurance carrier agrees to “defend and indemnify” the dog owner for the attack.
Common Mistake: Assuming your insurer already knows you own a dog. Almost all homeowners’ insurance policies cover dog attacks. However, if you own a home and have a dog, you should make sure the insurance company knows this. Failing to disclose your pet could create coverage complications after a bite.
When Insurance Has Limits or Exclusions
Once a dog has bitten someone, it poses an increased risk. In that instance, the insurance company may charge a higher premium, nonrenew the homeowner’s insurance policy, or exclude the dog from coverage.
Michigan does have some consumer protections in this area. Insurers cannot deny, cancel, or not renew a policy based on the insured’s dog’s breed alone. However, insurers can deny coverage or not renew a policy if, after receiving written notice from the insurer, the dog bites a person or attacks another animal and causes a claim to be paid under the policy.
The financial scale of these claims is significant. Liability claims related to dog bites and other dog-related injuries cost homeowners insurers $1,570 million in 2024, according to the Insurance Information Institute. The number of dog bite claims nationwide increased in 2024 to 22,658 — an 18.9 percent increase. The average cost per claim increased 18.3 percent in 2024 to $69,272.
If Coverage Is Insufficient
If the dog owner lacks insurance or has limited coverage, there are still ways to seek compensation. A victim may be able to pursue the owner’s personal assets, hold a landlord responsible if they knew about a dangerous dog, or determine whether a homeowners association was aware of previous incidents. In some cases, the victim’s own health insurance or homeowners policy may help cover medical expenses.
For renters who own dogs, it is important to have renters’ insurance if you are a renter and own a dog. Without it, you may have no financial buffer if your dog injures someone.

Criminal Charges for Dog Bites in Michigan
Civil liability and insurance claims are one thing — but Michigan law also opens the door to criminal prosecution in serious dog bite cases. This is an area many dog owners don’t consider until it’s too late.
When Criminal Charges Apply
You might be aware that you can be sued if your dog attacks someone, but in Michigan you may also be charged with a crime. If your dog mauls or attacks another person — or even another animal — you could face penalties ranging from a small fine to years in prison.
The severity of the criminal charge depends on the outcome of the attack and your prior knowledge of your dog’s dangerous tendencies:
- Minor injury (misdemeanor): When the dangerous animal attacks or bites a person and causes an injury that is not serious, you may be guilty of a misdemeanor punishable by any combination of 90 days in jail, a fine between $250.00 and $500.00, and 240 hours of community service work.
- Serious injury (felony): If your dangerous animal attacks and seriously injures another person, you may be guilty of a felony punishable by any combination of 4 years of imprisonment, a fine of $2,000.00, or 500 hours of community service.
- Death (involuntary manslaughter): If your dog causes the death of another person, you may be guilty of involuntary manslaughter, which is punishable by up to 15 years in prison, a fine of up to $7,500, and restitution to the victim’s family.
The Role of Prior Knowledge
An owner who knows that their dog is dangerous can face felony charges and very serious criminal penalties — including years in prison and thousands of dollars in fines — if that dog kills or seriously injures someone. This means the dangerous dog designation discussed in the previous section has direct criminal implications: once you’re on notice that your dog is dangerous, the standard for criminal liability shifts significantly.
Because the same incident can trigger civil damages, dangerous-animal hearings, and even criminal charges, both sides benefit from early, informed decisions. If you’re facing any of these proceedings, legal representation isn’t optional — it’s essential.
Key Insight: Michigan courts have some discretion in sentencing. According to the Michigan Supreme Court, judges can now decide what penalties are “reasonable” for a conviction, independently of the sentencing limits and requirements outlined in the criminal statutes. An experienced attorney may be able to argue for a more lenient outcome depending on the facts.
Statute of Limitations for Civil Claims
While criminal charges are brought by the state, victims also have a window to file civil lawsuits against you. The general rule is 3 years from the date of the bite (MCL 600.5805). For minors or incapacitated victims, the clock starts when the disability ends, but cannot exceed their 19th birthday. Miss these windows and the case evaporates, no matter how severe the injury.
Being a dog owner in Michigan comes with real legal responsibility. Whether your dog has bitten once or has a history of aggression, understanding these laws — from the moment a bite happens to potential criminal exposure — puts you in the best position to protect yourself, your pet, and others around you.
