The short answer

Massachusetts is a strict-liability state for dog attacks under M.G.L. c. 140 sec. 155. The owner or keeper of the dog is liable for the injury without any need to prove the animal had bitten before or that the owner knew it was dangerous, so the common-law one-bite rule does not apply here. The statute provides only two defenses: that the injured person was trespassing, or that the person was teasing, tormenting, or abusing the dog at the time. A child under the age of seven is presumed by the statute not to have done either, which strengthens claims involving young children. Recovery usually comes from the owner's homeowner or renter insurance. The three-year limitations period under M.G.L. c. 260 sec. 2A applies. Jim Glaser Law evaluates Massachusetts dog-bite cases at no cost. Dog-bite matters are accepted on contingency, meaning no attorney's fee unless and until the matter resolves with a recovery to the client; case-related costs and expenses are addressed in the written fee agreement.

Frequently asked questions

  • Do I have to prove the dog bit someone before to recover damages in Massachusetts?

    No. Massachusetts is a strict-liability state for dog attacks under M.G.L. c. 140 Β§ 155. The owner or keeper is liable for the injury without any proof that the animal had bitten before or that the owner knew it was dangerous. The common-law one-bite rule does not apply in Massachusetts.

  • What defenses can a dog owner raise against a bite claim?

    The statute at M.G.L. c. 140 Β§ 155 provides only two defenses: that the injured person was trespassing at the time of the attack, or that the person was teasing, tormenting, or abusing the dog. No other defenses apply under the strict-liability framework; ordinary negligence defenses such as failure to perceive a risk are not available.

  • What if the person who was bitten is a child?

    The statute expressly states that a child under seven years of age is presumed not to have been trespassing or teasing, tormenting, or abusing the dog. That presumption is significant because it forecloses both statutory defenses unless the owner can rebut it with clear evidence, which is rarely available.

  • Who actually pays a dog-bite judgment in Massachusetts?

    Recovery most often comes from the dog owner's homeowner insurance or renter's insurance policy, which typically covers dog-bite liability. The claim is made against the policy, not directly against the owner's personal assets in most cases. If the owner has no insurance, a direct claim against the owner remains available.

  • How does Jim Glaser Law charge for dog-bite representation?

    Dog-bite matters are accepted on contingency: no attorney's fee unless and until the matter resolves with a recovery to the client; case-related costs and expenses are addressed in the written fee agreement. The first telephone consultation is offered without charge.

How dog bites cases proceed under Massachusetts law

Massachusetts is a strict-liability state for dog bites, which sets a Massachusetts dog-bite case apart from most other injury claims. Under M.G.L. c. 140 sec. 155, the owner or keeper of a dog is liable for the damage the dog causes without the injured person having to prove that the dog had bitten before or that the owner knew the dog was dangerous. There is no common-law one-bite rule in Massachusetts. The statute removes the central hurdle that exists in many other states, which is proving the owner's prior knowledge.

The statute provides only two defenses, and they are narrow. The owner or keeper can avoid liability only by showing that the injured person was trespassing or committing another tort at the time, or was teasing, tormenting, or abusing the dog. Massachusetts adds an important protection for young children: a child under the age of seven is presumed not to have been trespassing, teasing, tormenting, or abusing the dog, which shifts the burden to the owner to prove otherwise. For a Massachusetts child-victim case, that presumption is a significant advantage.

Recovery in a Massachusetts dog-bite case usually comes from the owner's homeowner or renter insurance policy, which generally covers liability for dog bites, and in some circumstances a landlord may also bear responsibility, for example where the landlord knew of a dangerous dog on the property and had the ability to remove it. The standard three-year limitations period under M.G.L. c. 260 sec. 2A applies. Dog-bite injuries often involve scarring and disfigurement, infection risk, and lasting psychological trauma, and these effects are especially pronounced in children, so the case is built not only on the immediate wound but on the long-term physical and emotional consequences.

Massachusetts statutes and case law

  • M.G.L. c. 140 sec. 155. Strict liability for dog bites; the owner or keeper is liable without proof of prior bites or knowledge of dangerousness. The only defenses are that the victim was trespassing or committing a tort, or was teasing, tormenting, or abusing the dog. A child under seven is presumed to have done none of these.
  • M.G.L. c. 260 sec. 2A. Three-year statute of limitations for the dog-bite claim.
  • M.G.L. c. 231 sec. 85. Modified comparative negligence; relevant only in the narrow circumstances where a victim's conduct toward the dog is at issue.
  • M.G.L. c. 231 sec. 6B and 6C. Pre-judgment and post-judgment interest applied to a dog-bite damage award at statutory rates.
  • Massachusetts Rules of Civil Procedure. Procedural rules governing a filed dog-bite case in the appropriate Massachusetts trial court.

Common dog bites case patterns in Massachusetts

  1. A bite by a neighbor's or friend's dog in Massachusetts: strict liability under M.G.L. c. 140 sec. 155, with recovery typically through the owner's homeowner or renter policy.
  2. A child victim under seven: the statutory presumption protects the child from the teasing-or-trespassing defense, strengthening the the Commonwealth claim.
  3. A delivery or postal worker bitten while lawfully on the property: the lawful-presence element is satisfied, and strict liability applies.
  4. A landlord-tenant dog case where the landlord knew of a dangerous animal: the landlord may bear responsibility in addition to the owner or keeper.
  5. An injury from a dog knocking a person down rather than biting: the statute reaches damage the dog causes, not only bites, so a knock-down injury can qualify.

Typical timeline for a Massachusetts dog bites matter

In the first days after a Massachusetts dog bite, medical care and wound documentation come first. Bite wounds carry a high infection risk and often require careful cleaning, antibiotics, and sometimes surgical repair, and photographs of the wound at each stage of healing build the record. The dog owner and any insurance information should be identified, and the incident should be reported to the local authorities, which creates an official record.

Months one through six are the treatment and documentation phase. Scarring and disfigurement are evaluated as the wound heals, and where a child is involved, the psychological effects (fear of dogs, sleep disturbance, anxiety) are documented through treating providers. Because Massachusetts is a strict-liability state, the liability question is usually straightforward, so the case turns on documenting the full extent of the physical and emotional harm. A demand is prepared once the medical picture is clear.

If the owner's insurer does not offer a fair resolution, suit must be filed within three years under M.G.L. c. 260 sec. 2A and proceeds in the appropriate the Commonwealth court. Because liability is generally clear under M.G.L. c. 140 sec. 155, the contested issue is usually the value of the scarring, disfigurement, and psychological harm, and most filed cases resolve before trial.

What can be recovered in a dog bites case

  • Past and future medical expenses, including wound care, infection treatment, and any reconstructive or scar-revision surgery.
  • Pain and suffering for the experience of the attack and recovery.
  • Disfigurement and scarring, a separate damages category in Massachusetts that is often central to a dog-bite case.
  • Psychological harm, including fear, anxiety, and post-traumatic stress, which is especially significant for child victims.
  • Past lost wages and, where the injury is severe, future lost earning capacity.
  • Loss of consortium for a parent or spouse where applicable.

More Massachusetts dog bites questions

  • Do I have to prove the dog bit someone before to win my Massachusetts case?

    No. Massachusetts is a strict-liability state for dog bites under M.G.L. c. 140 sec. 155. The owner or keeper is liable for the harm the dog causes without you having to prove the dog had bitten before or that the owner knew it was dangerous. There is no one-bite rule here. The only defenses are that you were trespassing or committing a tort, or were teasing, tormenting, or abusing the dog, and those are narrow.

  • My child was bitten by a dog in Massachusetts. Does the law treat that differently?

    Yes. Under M.G.L. c. 140 sec. 155, a child under the age of seven is presumed not to have been trespassing, teasing, tormenting, or abusing the dog. That presumption shifts the burden to the dog owner to prove otherwise, which strengthens a child-victim case. Child dog-bite cases also focus heavily on scarring, disfigurement, and lasting psychological effects, which are documented through the child's treating providers in your the Commonwealth matter.

  • Who pays for a Massachusetts dog bite, the owner personally?

    Recovery usually comes from the owner's homeowner or renter insurance policy, which generally covers liability for dog bites, rather than from the owner's personal assets. In some circumstances a landlord may also bear responsibility, for example where the landlord knew of a dangerous dog on the property and could have removed it. The first telephone consultation identifies every policy and party that may be responsible for your the Commonwealth injury.

  • How long do I have to file a Massachusetts dog-bite claim?

    A dog-bite claim generally must be filed within three years of the bite under M.G.L. c. 260 sec. 2A. Acting sooner helps preserve the record, because photographs of the healing wound, the medical documentation, and the official incident report are strongest when gathered close to the event in your Massachusetts matter.
