Dog Bites in Massachusetts

In Massachusetts, dog attacks are governed by M.G.L. c. 140 § 155. The law imposes “strict liability” on dog owners and/or keepers of the dog. The law holds an owner or keeper of a dog strictly liable if the dog causes personal injury or property damage if the injured person was not trespassing, committing a crime, or otherwise teasing the dog.


Massachusetts law not only applies to dog bites but also applies to any injury that a dog causes to an individual. For example, if you are in a park or at a private residence and a dog jumps on you and causes you to fall and be injured, you may file a claim against the owner and/or keeper of the dog. It is important to know that in Massachusetts, owners and keepers of dogs are still liable for personal injury or property damage even if they had no prior knowledge that the dog would bite or cause injury.


Why Massachusetts’s Strict Liability Law Favors Victims


Many states follow a "one bite rule," which means a dog owner might avoid liability if their dog had no prior history of aggression. Massachusetts is different. Under the strict liability standard established by M.G.L. c. 140 § 155, the victim does not need to prove that the dog owner was negligent or that the dog had ever shown dangerous behavior before. The fact that the dog caused injury is, in most situations, enough to establish the owner's legal responsibility.


This makes Massachusetts one of the most victim-friendly states in the country when it comes to dog bite claims. However, exceptions do exist. The owner may raise defenses if the injured person was trespassing on the property, provoking or teasing the dog, or committing another wrongful act at the time of the incident. Children under seven years old receive additional protection under the law; they are presumed not to have provoked the dog unless evidence proves otherwise.


If you want to
know your rights after a dog bite, it's critical to understand how this statute applies to your specific situation. A dog bite attorney in Massachusetts can evaluate the circumstances of your case and identify the strongest path to recovery.

Animal Attack: Types of Injuries

An animal attack can cause serious injuries, varying in levels of severity. Some common types of attacks, including dog bites injuries are:


Broken bones, brain damage, spinal cord damage, scars, nerve damage, rabies, and more. Disfigurement and emotional effects are also a common phenomena in canine attacks.


Here is a closer look at the injuries our firm regularly sees in dog bite and animal attack cases:

  • Puncture wounds and lacerations: Dog bites frequently tear through skin, muscle, and tissue. Deep puncture wounds carry a high risk of infection because bacteria from the animal's mouth gets trapped beneath the skin's surface.
  • Infections and disease transmission: Bacterial infections such as cellulitis, MRSA, and pasteurella are common following animal bites. In rare but serious cases, rabies exposure requires immediate emergency treatment.
  • Nerve damage: Bites to the hands, arms, and face can sever or compress nerves, resulting in numbness, tingling, loss of motor function, and chronic pain that may become permanent.
  • Scarring and disfigurement: Children and adults alike may suffer visible facial scarring or disfigurement that requires multiple reconstructive surgeries. These injuries affect self-esteem and quality of life for years.
  • Psychological trauma: Dog attacks often cause PTSD, severe anxiety, phobias of animals, sleep disturbances, and depression. Children are especially susceptible to long-term psychological harm after a frightening attack.
  • Broken bones and fractures: Large dogs can knock victims to the ground, particularly children and elderly individuals, causing broken wrists, hips, ribs, and skull fractures.


An animal attack lawyer can help you get compensation for medical bills and loss of wages. They may also be able to recover compensation for non-economic damages such as emotional trauma and any physical pain endured. If the animal attack leads to death, the surviving loved ones can file a claim for
wrongful death damages with the help of an animal attack attorney. 


Whether you were bitten at someone's home, in a public park, or on a commercial property, a dog bite lawyer in Massachusetts can evaluate your claim and pursue the maximum recovery available under the law.

What claim options do I have?

The pet owner can be held responsible, but victims need help understanding their rights and pursuing a claim for compensation. Each case is different so the value of compensation will be different too. Compensation values of particular dog bites are determined by several factors including:

  • Medical expenses
  • How long the injuries have impacted your daily life
  • Lost wages due to missed work
  • Emotional and physical trauma
  • Scarring

At the Law Offices of Jason M. Ranallo, P.C., our dog attack attorneys can calculate the full value of the claim and help you get your compensation as quickly as possible.

What steps should I take after a dog bite?

  • The first step to take is to seek medical care. The risk of infection from a dog bite is far too great to ignore.
  • Next, identify the dog owner’s name, address, and proof of rabies vaccination.
  • Take pictures of your injuries to show evidence in possible insurance claims.
  • You may then pursue legal action against the owner or whomever is responsible for the care of the dog.



As long as you were lawfully in the particular place when you were bitten or injured, you can pursue a damage claim. An experienced dog attack lawyer at the Law Offices of Jason M. Ranallo, P.C. can help you understand your options. Learn more about how to

How to avoid dog attacks

Dog attacks can be prevented when the owners properly train and attend to their dogs. According to our leading dog attack lawyers, dog attacks happen because dog owners often fail to:

  • Keep the dogs fenced and secured
  • Train and socialize the dogs
  • Supervise the dogs
  • Provide medical care when the dogs are sick or injured
  • Post warnings of aggressive dogs on their property
  • Fulfill basic animal-care responsibilities

Never approach an unfamiliar dog, especially if it is sick or injured. We, at the Law Offices of Jason M. Ranallo, P.C, understand that it’s impossible to predict when dogs will attack and you can’t always avoid coming in contact with dangerous dogs. So if you, your child, or your loved one is a victim of animal attack, get in touch with us.

Dog Bite Lawyer in Boston: Serving the Greater Boston Metro Area

Boston and its surrounding communities see a significant share of Massachusetts dog bite incidents each year. Urban density, apartment living with shared hallways and common areas, and busy public parks all contribute to situations where dogs and people come into close contact, sometimes with dangerous results.


If you're looking for a dog bite lawyer in Boston, Attorney Jason Ranallo represents victims throughout the Boston metro area, including Dorchester, Roxbury, South Boston, Jamaica Plain, Brighton, and all surrounding neighborhoods. Our Dedham office is conveniently located just minutes from downtown Boston, making it easy for Boston-area residents to meet with us in person.


Urban vs. Suburban Dog Bite Scenarios in Greater Boston

Dog bite cases in Boston proper often involve different circumstances than those in suburban communities. In the city, attacks frequently occur in multi-unit housing buildings, on sidewalks, in dog parks, and near public transit stops. Liability questions can become complicated when a landlord knew about a dangerous dog in their building but failed to act, or when a dog walker lost control of an animal on a crowded street.


In suburban areas like Dedham, Canton, Braintree, Quincy, and Milton, bites often happen during visits to a neighbor's home, while jogging or walking through a residential neighborhood, or when a dog escapes an unfenced yard. Regardless of where the attack happened, Massachusetts strict liability law applies statewide.


Hospitals, Reporting, and Insurance in Boston Area Cases

After a dog bite in the Boston area, victims should seek immediate medical treatment. Major trauma centers such as Massachusetts General Hospital, Brigham and Women's Hospital, Beth Israel Deaconess, and Boston Medical Center all treat dog bite injuries regularly. Emergency room records become essential evidence in your case.


Massachusetts law requires that all dog bites be reported to the local board of health or animal control. In Boston, this means filing a report with the Boston Animal Care and Control division. The animal control officer will investigate the incident and may order the dog to be quarantined. These official reports serve as valuable documentation when building your legal claim.


Most dog bite claims in Massachusetts are covered by the dog owner's homeowners or renters insurance policy. An experienced
personal injury lawyer knows how to deal with these insurance companies and fight for the full value of your claim, not just the quick lowball settlement they first offer.

Compensation Available in Dog Bite and Animal Attack Cases

The financial toll of a dog bite can be staggering. Emergency room visits, follow-up surgeries, physical therapy, and ongoing psychological counseling add up fast. Massachusetts law allows dog bite victims to recover compensation for both economic and non-economic damages. Here is what you may be entitled to:

  • Medical expenses: All costs related to treating your injuries, from emergency room bills and ambulance fees to prescription medications, wound care, physical therapy, and follow-up visits.

  • Reconstructive surgery: Severe bites, particularly to the face and hands, often require plastic surgery or reconstructive procedures. These surgeries can span months or years, with each procedure adding to the total cost.

  • Lost wages and lost earning capacity: If your injuries prevent you from working during recovery, or if permanent damage reduces your ability to earn a living in the future, you can seek compensation for those financial losses.

  • Pain and suffering: Massachusetts does not cap pain and suffering damages in personal injury cases. The physical pain of a bite wound, the discomfort of recovery, and ongoing chronic pain are all compensable.

  • Emotional distress: Anxiety, PTSD, fear of dogs, nightmares, and depression following an attack are recognized as legitimate damages. This is especially significant in cases involving children.

  • Long-term disability and disfigurement: Permanent scarring, loss of mobility, and nerve damage that affects your daily activities are factored into the total value of your claim.


Every case is unique, and the total value depends on the severity of your injuries, the length of your recovery, and the long-term impact on your life. A dog bite lawyer in Massachusetts can calculate the full scope of your damages and make sure nothing is left off the table.

How Liability Is Proven in Dog Bite Cases

While Massachusetts strict liability law provides strong protections for victims, building a solid case still requires thorough documentation and investigation. Here is what goes into proving liability and maximizing your recovery:


Identifying the Dog's Owner or Keeper

The first step is establishing who owned, harbored, or was responsible for the dog at the time of the attack. Under M.G.L. c. 140 § 155, both the legal owner and anyone who was keeping the dog can be held liable. In some cases, a landlord who knowingly allowed a dangerous dog on their property may also share responsibility.


Documenting the Incident

Photographs of your injuries taken immediately after the attack, the location where it happened, and the dog itself are critical. If there were witnesses, their contact information and statements become valuable evidence. Filing a report with local animal control creates an official record that strengthens your claim.


Gathering Medical Records

Complete medical documentation connects your injuries directly to the attack. This includes emergency room records, surgical notes, physical therapy records, mental health treatment records, and bills for every medical expense you've incurred.


Witness Statements and Prior Incident History

Statements from people who saw the attack carry significant weight. Additionally, if the dog has a history of biting or aggressive behavior, prior complaints filed with animal control or neighbors' testimony about the dog's temperament can further support your case.


Handling the Insurance Claims Process

Most dog bite claims are filed against the owner's homeowners or renters insurance. Insurance adjusters are trained to minimize payouts. They may try to shift blame onto you, argue your injuries aren't as serious as they are, or pressure you into accepting a low settlement before you've finished medical treatment. Having an animal attack lawyer in MA on your side ensures you don't settle for less than your case is worth.
