As Seen On:










Dog bites happen in Brockton at parks, on sidewalks, in backyards, and at the homes of neighbors and acquaintances. Nationally, the United States Postal Service reported that Massachusetts mail carriers were bitten by dogs 116 times in 2023, confirmed from CBS Boston citing USPS data – and these are only the incidents involving letter carriers, a small fraction of the full picture. Across the United States, an estimated 4.5 million people are bitten by dogs each year, and more than 800,000 require medical attention, confirmed from the American Veterinary Medical Association. Dog bites drive bacteria deep under the skin and often cause infections, scarring, nerve damage, and lasting psychological effects that go well beyond the immediate wound.
When a dog bite happens in Brockton, Massachusetts law is on the injured person’s side. Under Massachusetts General Laws Ch. 140 Sec. 155, the dog’s owner – and in some cases the person keeping or controlling the dog – is strictly liable for injuries caused by the dog. The injured person does not need to show that the owner knew the dog had a history of biting. The only defenses are trespassing and teasing or provoking the dog.
Larson Law handles Brockton dog bite claims and dog attack cases across all of Plymouth County. If you were injured in a dog attack in Brockton, a Brockton dog bite lawyer can review your situation at no cost.
Under MGL Ch. 140 Sec. 155, a dog’s owner is liable for any damage caused by the dog to a person’s body or property. This is strict liability – the injured person does not need to prove the owner knew the dog was dangerous, that the dog had bitten before, or that the owner was negligent in any particular way. The statute also extends liability to the dog’s ‘keeper’ in some situations – the person who was in control of or responsible for the dog at the time of the Brockton dog bite attack, even if they are not the owner. This matters in Brockton dog bite cases where the dog was in someone else’s care, being walked by a dog walker, or staying at a neighbor’s property when the attack occurred.
The strict liability rule under MGL Ch. 140 Sec. 155 has two specific defenses. The first is trespassing – if the injured person was trespassing on the dog owner’s property at the time of the Brockton dog bite, the owner’s liability may be limited. The second is provocation – if the injured person teased, tormented, or abused the dog, liability may also be limited. These defenses are specific and narrow. Being lawfully present in a public place, on a sidewalk, or as an invited guest at someone’s home means neither defense applies to your Brockton dog bite claim. Insurers routinely raise provocation arguments to limit claims – having a Brockton dog bite lawyer ensures any such argument is met with the actual evidence from the attack.
Most Brockton dog bite claims are pursued through the dog owner’s homeowner’s insurance or renter’s insurance policy. Massachusetts law requires homeowner’s insurers to offer coverage for personal liability claims including dog bite attacks. If the owner rents and carries renter’s insurance, that policy may also provide liability coverage. An attorney can identify every applicable insurance policy and pursue the full scope of what the Brockton dog bite claim may support – medical bills, future treatment, lost wages, scarring, and pain and suffering.
Massachusetts follows a modified comparative fault rule under MGL Ch. 231 Sec. 85. In a Brockton dog bite claim, if you are found to be 51 percent or more at fault for the attack – for example, by actively provoking the dog – recovery is barred. Below that threshold, compensation is reduced in proportion to your share of fault. Insurers representing dog owners sometimes attempt to assign a share of fault to the victim to limit the claim. Having legal representation means any fault assignment reflects the actual facts of the Brockton dog bite attack.
The injuries from a Brockton dog bite attack can be serious and lasting. Understanding the full range of what a claim may cover is important to making sure nothing is overlooked.
Dog bites drive bacteria deep under the skin, creating serious infection risk even when the initial wound appears minor. Common Brockton dog bite injuries include puncture wounds, lacerations, crush injuries from the dog’s jaw pressure, facial scarring, nerve damage in the hands and arms, and in severe attacks, orthopedic fractures. Children bitten in Brockton are particularly vulnerable to facial and head injuries because of their height relative to most dogs. A Brockton dog bite claim may support recovery for all emergency treatment, follow-up care, reconstructive surgery, and any future treatment costs that can be projected with medical expert support.
A serious dog bite attack in Brockton frequently causes lasting psychological harm – post-traumatic stress, fear of dogs, anxiety in public spaces, and sleep disturbances. These effects are particularly pronounced in children and can affect daily life, school performance, and social functioning long after the physical wounds have healed. Pain and suffering damages in a Brockton dog bite claim may include these psychological effects alongside the physical pain and disruption the attack caused.
In rare but serious cases, a dog attack in Brockton may result in a fatality – particularly when young children or elderly victims are involved. When a fatal dog attack occurs in Brockton, the surviving family may have grounds for a wrongful death claim in Brockton under MGL Ch. 229 alongside any property damage or survival action claims.
The scope of what your Brockton dog bite claim may support depends on your injuries, the applicable insurance coverage, and the specific facts of the attack. We work through every applicable category so nothing is overlooked.

No. Massachusetts General Laws Chapter 140 Section 155 establishes strict liability for dog bite attacks. The injured person in a Brockton dog bite case does not need to prove the owner knew the dog was dangerous, that the dog had a prior history of biting, or that the owner was negligent in any particular way. Strict liability means the owner is responsible simply because their dog caused the injury. This makes Massachusetts one of the most victim-friendly dog bite states in the country. The only defenses the owner has are that the victim was trespassing or actively provoking the dog.
No, the strict liability rule under MGL Ch. 140 Sec. 155 applies regardless of the relationship between the victim and the owner. Being a guest at a neighbor’s home, a visitor on the property, or a pedestrian on a public sidewalk in Brockton all constitute lawful presence. The claim is the same whether the dog belonged to a stranger or a neighbor. Most Brockton dog bite claims against neighbors are pursued through the neighbor’s homeowner’s or renter’s insurance policy, which typically includes personal liability coverage for dog bite attacks.
MGL Ch. 140 Sec. 155 extends liability to the dog’s ‘keeper’ – the person who was in control of or responsible for the dog at the time of the Brockton dog bite attack. This means a dog walker, a neighbor watching the dog, or a friend who was handling the dog when the attack occurred may also bear liability under the strict liability statute. An attorney can identify every potentially liable party in a Brockton dog bite case – the owner, the keeper, and any other entity whose negligence contributed to the attack.
Get medical attention at Signature Healthcare Brockton Hospital or BMC South in Brockton right away. Dog bites drive bacteria deep under the skin and require prompt professional cleaning and treatment even when the wound appears minor – untreated bites frequently result in serious infection. Report the attack to Brockton Animal Control so the incident is officially recorded and the dog’s vaccination status can be verified. Photograph your injuries and the attack location before anything heals or changes. Get the dog owner’s contact information and any witness contact details. Do not give any recorded statement to the owner’s insurer before speaking with a lawyer.
It depends on the nature of the fault. The two specific defenses under MGL Ch. 140 Sec. 155 are trespassing and provocation – if neither applies to your Brockton dog bite situation, the strict liability rule controls and comparative fault is generally not a factor. If an insurer tries to argue you provoked the dog without clear evidence, that argument needs to be challenged. Even if some degree of comparative fault is found to apply under MGL Ch. 231 Sec. 85, recovery may still be available as long as your share of fault was less than 51 percent. Having a lawyer assess the specific facts of your Brockton dog bite attack is the best way to understand what defenses apply.
Prior bite history is irrelevant under Massachusetts strict liability law. MGL Ch. 140 Sec. 155 does not require the owner to have known the dog was dangerous, and the dog’s breed or bite history does not change the strict liability standard. Whether the dog had bitten before or was considered friendly by its owner has no bearing on the owner’s liability in a Brockton dog bite claim. This is the critical distinction between Massachusetts strict liability and the old ‘one bite rule’ that applies in some other states.
Most Brockton dog bite claims are paid from the dog owner’s homeowner’s insurance or renter’s insurance. Massachusetts law requires homeowner’s insurers to offer personal liability coverage, which includes dog bite attacks. If the owner rents and carries renter’s insurance, that policy may also provide coverage for your Brockton dog bite claim. If the attack happened at a commercial property – a business or rental property – the property owner’s commercial general liability policy may also be relevant. An attorney can identify every applicable policy. For a broader overview of how personal injury insurance claims work in Massachusetts, see our Boston personal injury attorney page.
The location affects which entity has jurisdiction over the incident report but not the strict liability standard itself. Brockton Animal Control handles dog bite reports within Brockton city limits. If the attack happened in a Brockton public park, on a sidewalk, or at a private property within Brockton, the strict liability rule under MGL Ch. 140 Sec. 155 applies the same way. The location also determines what surveillance footage or witness evidence may be available – a Brockton dog bite on a busy commercial street may have more available footage than an attack in a private backyard.
Yes. Children are actually the most common victims of dog bites nationally, and Massachusetts strict liability law protects them the same way it protects adult victims. A Brockton dog bite claim filed on behalf of a child is brought by a parent or guardian as the child’s legal representative. Children bitten in Brockton are particularly vulnerable to facial and head injuries because of their height relative to most dogs. The statute of limitations under MGL Ch. 260 Sec. 2A generally does not begin running until the child turns 18, providing additional time – but acting promptly preserves evidence and allows for immediate medical documentation of the injuries.
Under MGL Ch. 260 Sec. 2A, the statute of limitations for personal injury claims in Massachusetts is three years from the date of the Brockton dog bite attack. For children, the three-year period generally does not begin running until they reach age 18. Missing this deadline means losing the right to pursue compensation in court regardless of how clear the evidence is. However, the practical window for preserving important evidence – photographs of the injuries before they heal, Animal Control records, witness contact information, and the dog owner’s identity – is much shorter. Contacting a lawyer promptly after your Brockton dog bite attack protects all of this.

Under Massachusetts strict liability law, the owner’s knowledge or lack of knowledge about their dog’s behavior is not a defense. MGL Ch. 140 Sec. 155 imposes liability regardless of whether the owner believed the dog was gentle, had never shown aggression, or was surprised by the attack. The only defenses are trespassing and provocation. An owner’s claim that the attack was unexpected or out of character for the dog does not affect their legal liability in a Brockton dog bite claim under Massachusetts law.
