Maine Dog Laws: Licensing, Bite Liability, and Dangerous Dog Rules

Maine dog laws require every owner to license their dog each year, keep it from running at large, and accept near-strict liability if the dog injures someone off the owner’s property. Fines for a court finding that your dog is dangerous or a nuisance start at $250 and can reach $5,000, and ignoring a court order about a dangerous dog is a Class D crime. The rules below cover what you have to do, what you owe if your dog hurts someone, and how the dangerous-dog process works.

Annual Licensing

Every dog six months or older must be licensed through the municipality where it is kept.¹ The clerk will not issue a license without proof of a current rabies vaccination. If you get a new dog or your dog turns six months old between January 1 and October 15, you have ten days to license it.

The base fee is $6 a year for a spayed or neutered dog and $11 for an unaltered dog. Licenses follow the calendar year with a grace period through January 31. Miss that date and the state adds a $25 late fee. The late fee climbs to $70 if a court has designated the dog a nuisance and $150 if the dog has been designated dangerous.²

If you keep five or more dogs at one location for breeding, hunting, showing, training, sledding, or competition, you need a kennel license. One litter sold within a 12-month period does not by itself trigger it. A municipal kennel license costs $42 and covers up to ten dogs over six months old.³ Your local animal control officer must inspect the kennel each year before the license can be issued or renewed.

Keeping Your Dog Under Control

It is unlawful for any dog in Maine, licensed or not, to run at large. The only exception is a dog actively being used for hunting.⁴ There is no statewide leash-length rule for casual walks, but “at large” effectively means the dog must be on your own property or under your direct control. Towns can impose stricter rules, including specific leash mandates, so check with your clerk for the local version.

Liability if Your Dog Bites Someone

Maine applies a near-strict liability standard when a dog injures a person off the owner’s property. If your dog bites or otherwise hurts someone who is not on your premises at the time, you owe the full amount of damages. There is no “first bite free,” and the injured person does not have to prove you were careless or knew the dog was aggressive.⁵

The injured person’s own conduct reduces their recovery only if a court finds that person was more at fault than the owner.⁵ Someone teasing or provoking the dog may see a reduced award. A bystander or a mail carrier will not.

A different rule covers property damage. When your dog damages someone’s belongings or injures their animal, the injured party must prove you were negligent as owner or keeper. If the incident happens on your own property, ordinary negligence rules apply whether a person or an animal was hurt.

Check Your Insurance Before Something Happens

Standard homeowners and renters policies usually include dog bite liability, but limits and exclusions vary. Some insurers exclude certain breeds, and a prior claim can lead to higher premiums, nonrenewal, or an exclusion rider for a specific dog. If a court designates your dog as dangerous, Maine law requires you to carry at least $100,000 in liability insurance for the life of the animal.⁶ Reviewing your policy now gives you a chance to close gaps rather than find them after a claim.

Nuisance Dog vs. Dangerous Dog

Maine sorts problem dogs into two tiers based on how badly the dog hurt or threatened someone. Both require a court determination after an investigation, not just a complaint to animal control.

A dog is a nuisance if it causes bodily injury short of serious bodily injury to a non-trespassing person or domesticated animal, or if its aggressive behavior makes a reasonable person off the owner’s premises fear imminent bodily injury.⁷

A dog is dangerous if it kills or inflicts serious bodily injury on a non-trespassing person or domesticated animal, or if it makes a reasonable, non-aggressive person off the premises fear imminent serious bodily injury.⁷ The same definitions cover wolf hybrids.

What a Dangerous Dog Order Can Require

When a court finds a dog dangerous, the judge has broad authority over the conditions that follow. Violating any of them is a crime, so the details matter. A court can order any combination of:

A secure enclosure at least six feet high, designed to keep young children out and the dog in, with the court deciding whether a secure top and bottom are required and whether confinement should be permanent.⁶
A basket-style muzzle whenever the dog is off your property or outside the enclosure, held on a leash no longer than three feet with a tensile strength of at least 300 pounds, under your direct control.
At least $100,000 in liability insurance covering the dog for its entire life.
Restitution for any damages the dog caused to a person or property.
Euthanasia, if the dog killed or caused serious injury or the court concludes the risk to the community is too high.

Courts can also require you to notify law enforcement or animal control immediately if the dog escapes or is involved in another incident. Orders can be modified later, but only by the court.

Fines and Criminal Exposure

A court finding that your dog is dangerous or a nuisance carries an automatic civil fine of at least $250 and up to $5,000, plus court costs. None of that can be suspended.⁶ The fine is on top of any restitution the court orders for the victim’s injuries or property damage.

Refusing or neglecting to comply with a dangerous-dog court order is a Class D crime.⁶ A conviction can lead the court to ban you from owning or possessing any dog, or even having one on your property, for a set period or permanently. This is where a civil matter becomes a criminal record and a possible lifetime bar on dog ownership.

Separately, failing to license on time adds $25 for a standard dog, $70 for a nuisance dog, or $150 for a dangerous dog on top of the regular fee.²

Maine Does Not Allow Breed-Specific Bans

Maine prohibits municipalities from enacting breed-specific ordinances. Towns and cities can adopt animal control rules stricter than state law, but they cannot single out particular breeds for bans or extra restrictions.⁸ A dangerous-dog designation turns on the individual animal’s behavior. If a landlord or municipality tells you a specific breed is banned under state law, that is incorrect.

Contesting a Dangerous Dog Designation

If your dog is the subject of a dangerous-dog proceeding, you have the right to appear in District Court or Superior Court and present evidence. The court weighs the severity of the incident, the dog’s history, whether the victim was trespassing or provoking the animal, and the overall risk to the community.⁷

If a court issues an emergency ex parte order seizing your dog before a full hearing, you can move to dissolve or modify it with as little as two days’ notice.⁶ Existing orders can also be modified later. Documentation does the heavy lifting: veterinary records, behavioral assessments, witness statements, and proof that you have already installed a secure enclosure or completed obedience training all count. An owner who arrives with a plan tends to fare better than one who argues only that the dog has never done this before.
