You were walking through your neighborhood, perhaps enjoying a sunny afternoon in a Boston park, when the unthinkable happened. In a split second, a dog lunged, and now you are dealing with painful injuries, medical bills, and a fair amount of shock. During this stressful time, you might hear people talk about the “one-bite rule.” They might tell you that if the dog has never bitten anyone before, the owner isn’t responsible.
Here is the good news: when it comes to Massachusetts dog bite law, that “rule” is a total myth.
In many states, a dog truly does get “one free bite” before the owner is held legally responsible. But Massachusetts is different. Our laws are some of the most protective in the country for victims. At Joel H. Schwartz, P.C., we have spent over 60 years helping people navigate these exact situations. We know that a dog attack is more than just a physical injury; it is a traumatic event that can change your life.
Understanding the “One-Bite Rule” Myth
The “one-bite rule” is an old legal concept. It suggests that a dog owner is only responsible for an injury if they knew: or should have known: that their dog was dangerous. Usually, this meant the dog had to have bitten someone at least once before. If it was the dog’s first time showing aggression, the owner could often walk away without paying a dime for the victim’s medical care.
In Massachusetts, we don’t play by those rules.
Under Massachusetts General Law Chapter 140, Section 155, the state follows a “Strict Liability” standard. This means that if a dog causes injury to a person or damage to property, the owner or keeper is liable. It does not matter if the dog was a “good boy” for ten years. It does not matter if the dog had never growled at a soul. If the dog bites you, the owner is responsible for the damages.

Why Strict Liability is Your Best Friend
Strict liability sounds like a heavy legal term, but for you, it simply means a clearer path to justice. You do not have to prove that the owner was negligent. You don’t have to track down neighbors to ask if the dog was aggressive in the past.
As a dog bite lawyer Massachusetts residents trust, we focus on the facts of your specific incident. The law is designed to ensure that victims are compensated for their losses without having to jump through impossible hoops. Whether the injury happened on public property or while you were lawfully on private property, the owner’s responsibility is clear.
This law doesn’t just apply to teeth meeting skin, either. Massachusetts strict liability covers:
- Physical Bites: The most common and obvious injury.
- Scratches: These can lead to serious infections or permanent scarring.
- Knock-downs: If a large dog jumps on you and causes you to fall, resulting in a broken bone or head injury, the owner is still liable.
- Property Damage: If a dog destroys your property, the law covers that too.
If you are more confused than ever about your accident, remember that the law is on your side. You deserve to have your medical bills paid and your pain acknowledged.
Protecting the Most Vulnerable: Children Under Seven
Dog bites are particularly devastating when they involve children. Because of their size and curiosity, children are often bitten on the face or neck, leading to lifelong scarring and emotional trauma.
The Massachusetts dog bite law includes a very specific and powerful protection for young children. Usually, an owner might try to argue that the victim was “teasing” or “tormenting” the dog to avoid liability. However, for children under the age of seven, the law presumes the child did nothing wrong.
It is almost impossible for a dog owner to claim a six-year-old was at fault for an attack. This “presumption of innocence” for young children makes it much easier for parents to seek the help their family needs. We take these cases very seriously because we know the long-term impact an attack can have on a child’s sense of safety.

Common Defenses (And Why They Often Fail)
Even with strict liability, insurance companies will try to find a way out. They are in the business of keeping their money, not giving it to you. They might try to claim:
- Trespassing: They may say you weren’t supposed to be on the property.
- Provocation: They might claim you teased or hit the dog.
- Abuse: They might argue you were hurting the animal.
This is where having an experienced Boston dog bite lawyer becomes essential. We know how to shut down these defenses. We gather the evidence, interview witnesses, and look at the physical layout of the scene to prove you were acting lawfully and reasonably. If you weren’t trespassing and weren’t abusing the animal, the owner is responsible. It is as simple as that.
What Should You Do After a Dog Bite?
The moments following an attack are chaotic. However, the steps you take now can significantly impact your ability to recover compensation later.
- Seek Medical Attention Immediately: Even a small bite can become infected. Dog mouths carry a lot of bacteria. Plus, you need a professional medical record of the injury.
- Identify the Dog and Owner: Get the owner’s name, address, and contact information. If there were witnesses, get their names too.
- Report the Incident: Contact animal control or the local police. A formal report is a vital piece of evidence.
- Take Photos: Document your injuries, the location of the attack, and: if possible: the dog.
- Don’t Sign Anything: An insurance adjuster might call you quickly with a “settlement.” Do not sign it. These initial offers are almost always much lower than what you actually deserve.
Once you have addressed your immediate health needs, find the right lawyer to handle the rest. You need someone who knows the local courts and the specific nuances of Massachusetts statutes.

How Much is Your Case Worth?
This is the question every victim asks, and rightfully so. A dog bite can lead to thousands of dollars in medical bills, lost wages from missed work, and the need for future plastic surgery to address scarring.
When we evaluate your claim, we look at:
- Medical Expenses: Past, present, and future treatments.
- Scarring and Disfigurement: This is a major factor in dog bite settlements.
- Pain and Suffering: The physical pain and the mental anguish (like developing a fear of dogs).
- Lost Wages: Money you lost because you couldn’t work while recovering.
