Maine Dog Bite Law decides who pays when a dog injures someone — and the answer changes a great deal from one state to the next. This guide explains whether Maine uses strict liability or the one-bite rule, how long you have to file, how leash and dangerous dog rules work, and exactly how a homeowners policy responds. Whether you own a dog in Maine or you were bitten by one, Maine Dog Bite Law is what determines the outcome.
Maine Dog Bite Law is summarized here in plain English. Everything in this guide was verified against Maine statutes, the state courts, and Insurance Information Institute claim data as of August 2026.
In This Maine Dog Bite Law Guide:
Maine Dog Bite Law: Strict Liability or One-Bite Rule?
Maine is a strict liability state for dog bites. That means a dog owner is responsible for the injury even if the dog had never bitten anyone before and even if the owner did everything right. The victim does not have to prove the owner was careless.
The governing statute is 7 M.R.S. 3961. Statutes are amended, so confirm the current text before relying on it in a claim.
Maine imposes strict liability on a dog’s owner or keeper when the dog injures a person who is not on the owner’s or keeper’s premises at the time of the injury — the victim does not have to prove the owner was careless or knew the dog was dangerous. If the injury happens on the owner’s or keeper’s own property, strict liability does not apply and the victim must instead prove ordinary negligence. The victim’s own fault does not reduce recovery for physical injury unless the court finds the victim’s fault exceeded the owner’s or keeper’s fault.
The Maine rule is broad — it covers not just bites but other injuries a dog causes, such as knocking a person down.
Filing Deadline Under Maine Dog Bite Law
A dog bite lawsuit in Maine must be filed within 6 years of the date of the injury (14 M.R.S. 752). Miss that deadline and the claim is normally barred no matter how strong it is.
The deadline for notifying an insurance company is much shorter than the deadline for filing suit. Most homeowners policies require prompt notice, so report the incident to the insurer right away even if you have not decided whether to sue.
How Maine Dog Bite Law Treats Leash Laws and Dangerous Dogs
7 M.R.S. 3911 makes it unlawful for any dog, licensed or unlicensed, to be at large except when used for hunting, and 7 M.R.S. 3907 defines “at large” as off the owner’s premises and not under the control of a person whose presence and attention would reasonably control the animal. This is a statewide running-at-large restraint rule rather than a literal leash mandate; under 7 M.R.S. 3950 municipalities may adopt stricter local leash ordinances, and less restrictive local rules are invalid.
7 M.R.S. 3952-A governs keeping a dangerous dog or a nuisance dog (the older 7 M.R.S. 3952 was repealed and replaced), with “dangerous dog” and “nuisance dog” defined at 7 M.R.S. 3907(12-D) and (20-A) based on the individual dog’s conduct toward a non-trespassing person or domesticated animal.
A court finding must impose a fine of not less than 250 and not more than 5000 plus costs, none suspendable, and may order confinement in a secure enclosure, a basket-style muzzle with a leash no longer than 3 feet and 300-pound minimum tensile strength when off the premises, sterilization, microchipping, behavioral evaluation, or euthanasia.
Leash rules matter far beyond the ticket. In a strict liability state, breaking a leash ordinance is powerful evidence of negligence, and it can defeat an owner’s defense outright.
Maine Dog Bite Law and Homeowners Insurance
Dog bites are normally paid under the personal liability section of a standard homeowners policy — Coverage E — not under the part that repairs your house. Renters policies carry the same liability coverage.
Two other pieces of the policy come into play. Medical payments coverage (Coverage F) pays a modest amount of the injured person’s medical bills with no finding of fault, which often settles a minor bite quietly. And an umbrella policy sits above your liability limit — the single most useful thing a dog owner in Maine can buy.
Coverage is not automatic. Most policies exclude injuries to people who live in your household, deliberate acts, and business-related animals. Some exclude a dog with a prior bite on record. Read the exclusions before you need them, not after.

Unique to Maine: Maine bars breed-specific local ordinances (7 M.R.S. 3950) and bars breed-based property insurance discrimination (24-A M.R.S. 3061) — a rarer pairing of both protections. A dog that bites triggers a mandatory 10-day rabies observation/quarantine, and animal control officers must notify the Maine CDC of suspected rabid animals. 7 M.R.S. 3961-A creates a separate cause of action for attacks on service or assistance animals, and 7 M.R.S. 3962-A gives a provocation/leashed-on-own-property defense for animal-on-animal injury claims. No state dog bite victim compensation fund and no breed registry.
Dog Bite Claim Costs in Maine
Maine Dog Bite Law decides who is liable. The claim figures below show what that liability actually costs when it lands.
State-level claim counts for Maine were not available from the Insurance Information Institute at the time of writing. Nationally, dog bite and dog-related injury claims are among the costliest homeowners liability claims, and the average payout has risen every year for over a decade.
| Typical liability limit | $300,000 |
Maine Dog Bite Law, Breed Restrictions and Insurance Exclusions
Maine law bars cities and counties from banning specific breeds, so a local pit bull ordinance is not enforceable against you here.
Good news for Maine dog owners: state law bars insurers from refusing, cancelling, or surcharging a homeowners policy purely because of a dog’s breed.
Breeds most often excluded or surcharged by insurers:
- NONE — 24-A M.R.S. 3061 bars Maine insurers from cancelling
- refusing to issue or renew
- or surcharging a property insurance policy solely because of the breed of dog owned
- unless that specific dog has been designated dangerous under 7 M.R.S. 3907(12-D)
Landlord and Property Owner Liability
Maine has no dog-bite statute imposing liability on landlords; 7 M.R.S. 3961 reaches only the dog’s owner or keeper, so a landlord is reached through ordinary common-law negligence and premises liability. A landlord generally must have known or had reason to know the tenant’s dog was dangerous and had the ability to remove or control it — commonly in shared common areas — before liability attaches; merely renting to a tenant who owns a dog is not enough. A landlord who exercises enough control over the animal could alternatively fall within the statutory definition of “keeper.”
Under Maine Dog Bite Law the tenant who owns the dog is the first target of a claim, but a landlord with knowledge of a dangerous animal can be pulled in alongside them.

Defenses Available Under Maine Dog Bite Law
Defenses recognized in Maine:
- Trespassing
- Provocation
- Comparative fault
These defenses rarely erase a claim by themselves. They more often reduce what an owner pays, which under comparative fault rules can still be a substantial difference.
How to Lower Your Liability Risk
Maine Dog Bite Law sets the standard you will be judged against. These are the steps that reduce both the chance of a bite and the size of the bill if one happens:
- Raise your liability limit. Going from $100,000 to $300,000 usually costs very little per year.
- Add an umbrella policy. $1 million of extra liability typically runs $150-$300 a year.
- Tell your insurer about the dog. A non-disclosed dog is a reason to deny the claim later.
- Check your local leash ordinance. A violation is evidence against you in a civil case.
- Secure the yard and post a sign. Fencing and gate latches prevent the bite in the first place.
- Document training and vet visits. A record of responsible ownership supports the defense that you had no notice the dog was dangerous.
