Dog Bites in Cambridge

How dog bites cases proceed under Massachusetts law

Massachusetts is a strict-liability state for dog bites, which sets a Cambridge 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 Cambridge, Middlesex County child-victim case, that presumption is a significant advantage.

Recovery in a Cambridge 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 Cambridge

1. A bite by a neighbor's or friend's dog in Cambridge: 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 Middlesex County 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 Cambridge dog bites matter

In the first days after a Cambridge 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 Middlesex County 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 questions Cambridge residents ask about dog bites

• Do I have to prove the dog bit someone before to win my Cambridge 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 Cambridge. 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 Middlesex County matter.

• Who pays for a Cambridge 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 Middlesex County injury.

• How long do I have to file a Cambridge 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 Cambridge matter.
