As Seen On:
A Massachusetts dog bite claim turns on strict liability.
Massachusetts has one of the strongest dog bite laws in the country, and it works in the victim’s favor from the very first day. Under the strict liability statute, the owner or keeper of a dog is responsible for the harm the dog causes, and the injured person does not have to prove the owner was careless or knew the dog was dangerous. There is no “one free bite” rule here: a dog with a spotless history still leaves its owner fully liable. The law reaches far more than puncture wounds, covering tearing and scarring, infection, nerve and tissue damage, the lasting fear and emotional trauma that follow an attack, and even wrongful death. Children are the most frequent victims, and because they are small, their wounds are often to the face, head, and neck, where scarring is hardest to undo and where reconstructive surgery may be needed years later. The law gives children an added layer of protection as well. Most claims are paid not out of an owner’s own pocket but through homeowner’s or renter’s liability insurance, which means pursuing a claim rarely means going after a neighbor, friend, or relative personally; it means reaching the policy that exists for exactly this situation. What a claim ultimately turns on is proof: identifying the owner or keeper, documenting the attack and the injuries, locating the right insurance, and acting before scenes change and memories fade. The same strict liability framework applies when other domestic animals attack and cause injury. Getting those pieces right from the start is what separates a fully covered injury from a denied or underpaid claim.

State law makes a dog owner answer for an attack.
Strict liability under Chapter 140, Section 155
Massachusetts dog bite claims are governed by MGL Ch. 140 Sec. 155, a strict liability statute. The owner or keeper of a dog is liable for any damage the dog does to a person’s body or property, and the injured person need not show negligence or any prior history of aggression. This is why Massachusetts is described as having no “one free bite” rule: the first bite already counts. A “keeper” is anyone harboring or controlling the dog at the time, not only the legal owner, so a dog sitter or a relative watching the animal can be on the hook. The statute covers the full range of harm an attack causes, including disfigurement and, in the worst cases, wrongful death, which the surviving family may pursue under MGL Ch. 229. Because liability does not depend on proving fault, the central questions become who owned or kept the dog, what the dog did, and which insurance policy responds.
The three statutory defenses, and the under-seven rule
The statute carves out only narrow defenses. An owner escapes liability only if, at the time of the attack, the injured person was committing a trespass or another tort, or was teasing, tormenting, or abusing the dog. Those are the sole exceptions, and the owner carries the burden of proving one of them applies. Massachusetts adds a powerful protection for young children: if the victim was under seven years old, the law presumes the child was not trespassing, teasing, or abusing the dog, and the owner must prove otherwise to avoid liability. Insurers routinely raise provocation in an effort to shift blame onto the victim, so the specific facts of how the encounter began, and any witnesses to it, often decide the strength of the claim.
Dangerous dog findings and insurance recovery
Beyond the damages claim, a city or town can hold a dangerous dog hearing under MGL Ch. 140 Sec. 157, which can order a dog restrained, muzzled, or in severe cases euthanized; that proceeding is separate from the victim’s civil claim but can supply useful evidence of the dog’s history and the owner’s knowledge. In practice, recovery comes through the owner’s homeowner’s or renter’s liability insurance, sometimes supplemented by an umbrella policy when injuries are catastrophic. In rental situations, a landlord who knew a tenant kept a dangerous dog and allowed it to remain can sometimes share responsibility. Identifying every policy and every party that may respond is a core part of building the claim.
Most Massachusetts dog bite claims trace to homeowner insurance.
Where Massachusetts dog attacks happen
Dog attacks happen in every kind of Massachusetts community, from dense Boston neighborhoods to suburban yards and rural towns, and most occur in or around a home rather than in a public space. Visitors, houseguests, and children at a relative’s or neighbor’s home are common victims, as are delivery drivers, postal carriers, meter readers, utility workers, and anyone whose job brings them onto another person’s property. Letter carriers are bitten in large numbers every year, and the post office tracks attacks by city. Attacks also occur on sidewalks, in parks, at dog parks where multiple animals mix, and on trails and bike paths when a dog is off-leash or slips its restraint. The setting matters because it often determines which insurance policy responds and who, beyond the person holding the leash at that moment, may be legally responsible for the harm.
Who is liable beyond the owner
The statute reaches both the owner and the keeper, meaning anyone who was harboring or controlling the dog at the time, such as a dog sitter, a household member, or a friend watching the animal while the owner is away. If the owner is a minor, the parent or guardian stands liable in their place. In rental housing, a landlord who knew a tenant kept a dangerous dog and permitted it to remain can sometimes share liability, particularly in shared hallways, yards, and other common areas. Sorting out these roles early is essential, because the correct defendant and the policy that actually pays are not always the obvious person at the scene, and naming the wrong party can stall a claim for months.
Insurance, reporting, and deadlines that matter
Because most claims are paid through homeowner’s or renter’s liability coverage, the practical work of a claim is identifying that policy and preserving proof before accounts shift and records disappear. Photographs of the injuries and the location, prompt medical treatment, the names of any witnesses, and a report to the local animal control officer or board of health all strengthen the claim and help establish the dog’s history. When an owner has no insurance at all, an umbrella policy or other coverage may still respond, which is why every avenue is checked. A Massachusetts personal injury claim generally must be filed within three years under MGL Ch. 260 Sec. 2A, though for a child injured by a dog that deadline does not begin to run until the child turns eighteen. Acting early protects both the evidence and the deadline.
Recovery can cover scarring, surgery, and trauma.
What a dog bite claim can recover depends on the severity of the attack, the depth and location of the wounds, whether any scarring or disfigurement is permanent, and the emotional toll that follows. Facial and hand injuries, common in children, often require reconstructive surgery and leave lasting marks.

Common questions after a Massachusetts dog attack.
Is there really no "one free bite" rule in Massachusetts?
Correct. Under MGL Ch. 140 Sec. 155, Massachusetts applies strict liability, so a dog owner is responsible for the first bite just as much as a later one. You do not have to show the dog had ever bitten before or that the owner knew it was dangerous. The owner’s lack of warning is not a defense.
The owner says I provoked the dog. Does that end my claim?
Not by itself. The only conduct that defeats a claim is genuinely teasing, tormenting, or abusing the dog, or committing a trespass or other tort, and the owner must prove it happened. Ordinary contact, walking past, or a child’s innocent behavior is not provocation. Insurers raise this defense often, but it rarely holds up against the actual facts and witnesses.
My child was bitten. Are there extra protections?
Yes. Under MGL Ch. 140 Sec. 155, a child under seven is presumed not to have provoked or trespassed, and the owner carries the burden of proving otherwise. Children’s bites are frequently to the face and require reconstructive care, so the claim should account for future treatment. A parent or guardian brings the claim, and under MGL Ch. 260 Sec. 2A the filing deadline does not start until the child turns eighteen.
The dog belongs to a friend or family member. Do I have to sue them personally?
Almost never personally. Dog bite claims are typically paid through the owner’s homeowner’s or renter’s liability insurance, which exists for exactly this kind of accident. Pursuing the claim means dealing with the insurance company, not draining a friend or relative’s savings, and most people in that position would rather their insurance respond than see you go uncompensated.
How long do I have to file a Massachusetts dog bite claim?
Under MGL Ch. 260 Sec. 2A, you generally have three years from the date of the attack to file a personal injury claim in Massachusetts. For a child, the three-year clock does not begin until the child turns eighteen. Even so, acting promptly matters, because evidence, witnesses, and the dog’s history are easiest to document soon after the attack.
The dog never bit anyone before. Can I still recover?
Yes. Massachusetts strict liability under MGL Ch. 140 Sec. 155 does not require any prior history of aggression. A dog with no record of biting still leaves its owner fully liable for the harm it causes. The absence of a prior incident is not a defense, although a documented history can add weight, including in a dangerous dog proceeding.
I was attacked by an animal other than a dog. Does this law apply?
The dog bite strict liability statute is specific to dogs, but you may still have a claim for an attack by another animal under ordinary negligence principles, particularly where the owner knew or should have known the animal was dangerous. The path is different, but an injury caused by someone else’s animal can still be a compensable claim worth reviewing.
What is a dangerous dog hearing?
It is a municipal proceeding under MGL Ch. 140 Sec. 157 in which a city or town can declare a dog dangerous and order it restrained, muzzled, or in severe cases euthanized. It is separate from your civil injury claim, but findings and testimony from the hearing can provide useful evidence of the dog’s history and the owner’s knowledge.
Can a landlord be held responsible for a tenant’s dog?
Sometimes. A landlord is not automatically liable, but one who knew a tenant kept a dangerous dog and allowed it to remain, especially in shared common areas, can share responsibility. Whether a landlord is on the hook depends on what they knew and what control they had, which is one of the things we investigate early.
I was bitten on the job as a delivery or postal worker. What are my options?
You may have more than one avenue. A delivery driver, postal carrier, or other worker bitten on the job can bring a strict liability claim against the dog’s owner under MGL Ch. 140 Sec. 155 and may also have a workers’ compensation claim through their employer. The two can proceed together, and the comp insurer’s lien is handled out of any recovery.
The dog was euthanized after the attack. Does that affect my claim?
No. Your civil claim for the injuries is independent of what happens to the dog. A dangerous dog finding or even euthanasia under MGL Ch. 140 Sec. 157 does not erase the owner’s liability; if anything, an official finding that the dog was dangerous can support your claim by documenting the risk the owner allowed.
The owner has no insurance. Can I still recover?
Possibly. Even without standard homeowner’s coverage, an umbrella policy, a separate renter’s policy, or other coverage may respond, and in some cases the owner is pursued directly. Because the right source of recovery is not always obvious, every potential policy and responsible party is checked before a claim’s value is written off.
