A dangerous dog declaration in Maine is not an administrative checkbox — it is a court-driven legal process that can permanently change how you own and keep your dog. Whether a complaint has been filed against your pet or you simply want to understand the law before an incident occurs, knowing exactly how Maine’s system works puts you in a far better position to protect both your dog and your rights.
Maine governs dangerous and nuisance dogs primarily through Title 7, Chapter 727 of the Maine Revised Statutes, with definitions anchored in 7 MRS §3907 and enforcement procedures set out in §3952-A. The law was significantly updated in 2018 and the text reflects changes through the First Special Session of the 132nd Maine Legislature. This guide walks you through every stage of the process so you know what to expect.

What Makes a Dog “Dangerous” Under Maine Law
Maine law draws a precise legal line between a “dangerous dog” and a “nuisance dog,” and the distinction matters enormously for the penalties you could face. Under 7 MRS §3907(12-D), a “dangerous dog” means a dog or wolf hybrid that causes the death of or inflicts serious bodily injury on an individual or a domesticated animal who is not trespassing on the owner’s or keeper’s premises at the time of the injury or death; a dog or wolf hybrid that causes a reasonable and prudent person who is not on the owner’s premises and is acting in a reasonable and nonaggressive manner to fear imminent serious bodily injury by assaulting or threatening to assault that individual or their domesticated animal; or a dog or wolf hybrid that inflicts bodily injury on an individual or a domesticated animal not trespassing on the premises and has previously been determined by a court to be a nuisance dog.
That third prong is important: a dog that was previously labeled a nuisance dog and then injures someone automatically qualifies for the more serious dangerous dog designation. Maine does not have breed-specific laws, so the classification is based entirely on the dog’s behavior, not its breed or appearance.
Maine also recognizes a separate, lesser category. A nuisance dog is one that has engaged in threatening or damaging behavior that does not rise to the level of serious bodily injury. A dog may only be classified as a nuisance dog once. If the same dog causes injury after that nuisance finding, it moves into dangerous dog territory. You can read how other states approach similar thresholds in our guides to dangerous dog declarations in Georgia and dangerous dog declarations in Virginia.
Key Insight: Provocation is a recognized factor under Maine law. A dog that bites someone who was actively provoking it on the owner’s property, with no prior assault history, does not automatically qualify as dangerous. Document any evidence of provocation carefully from the start.
Who Can File a Dangerous Dog Complaint in Maine
Maine’s complaint statute is deliberately broad. A person who is assaulted or threatened with bodily injury by a dog, a person witnessing such an assault or threatened assault against a person or domesticated animal, a person with knowledge of such an assault or threatened assault against a minor, or a person whose property or crops have been damaged by a dog, within 30 days of the incident, may make a written complaint to the sheriff, local law enforcement officer, or animal control officer that the dog is a dangerous dog or a nuisance dog.
That means the complainant does not have to be the person directly harmed. A bystander who witnessed an attack, a neighbor who saw a dog threaten a child, or a farmer whose livestock was injured can all file. The 30-day window runs from the date of the incident, so timely reporting is required on the complainant’s side as well.
For the purposes of this chapter, “domesticated animal” includes, but is not limited to, livestock as defined in section 3907, subsection 18-A. This means complaints can arise from incidents involving farm animals, not just household pets or people.
Complaints are submitted in writing to your local animal control officer (ACO), the county sheriff’s office, or a local law enforcement officer. Maine’s Animal Welfare Program can be reached at (207) 287-3846 or animal.welfare@maine.gov if you have questions about which agency has jurisdiction in your municipality.
How the Dangerous Dog Declaration Process Works in Maine
The process moves through three distinct stages: investigation, summons, and court hearing. Understanding each stage helps you prepare an effective response.
- Written Complaint Filed: A complainant submits a written complaint within 30 days of the incident to a sheriff, local law enforcement officer, or ACO.
- Investigation: A representative of the sheriff’s department, a local law enforcement officer, or an animal control officer appointed by the municipality shall investigate and document the complaint.
- Civil Violation Summons: Upon completion of the investigation, the investigator may issue a civil violation summons for keeping a dangerous dog or a nuisance dog. Issuance is not automatic — the officer exercises discretion based on the evidence gathered.
- Pre-Hearing Interim Order: After a summons is issued but before the court hearing, if the dog poses an immediate or continuing threat to the public, an ACO, sheriff, or local law enforcement officer may give the owner a written order to muzzle, restrain, or confine the dog.
- Court Hearing: The matter goes before a court of competent jurisdiction. Both the complainant and you as the owner have the opportunity to present evidence.
- Court Finding: If, upon hearing, the court finds that the dog is a dangerous dog as defined in section 3907, subsection 12-D, the court shall impose a fine and issue mandatory and discretionary orders governing the dog’s future.
All records of the outcome of the investigation must be kept by the municipality for the life of the dog, plus two years. This means the record does not disappear if you move to another municipality within Maine.
The process in Maine differs from states like Indiana or Ohio, where administrative hearings before local boards may replace or precede court proceedings. In Maine, the court is the decision-maker from the outset.
Your Rights as a Dog Owner During the Process in Maine
Because a dangerous dog declaration is a civil court proceeding, you have meaningful procedural rights that an administrative process might not afford. You are entitled to notice of the complaint and the hearing, and you have the right to appear before the court, present evidence, and challenge the complainant’s account.
Before the hearing, if an interim confinement or muzzle order is issued against your dog, you can challenge it. The court shall hear and determine the motion, and the hearing may be advanced on the docket and receive priority over other cases when the court determines that the interests of justice so requires. This means urgent situations can be addressed quickly.
The owner or keeper shall submit an affidavit setting forth specific facts to substantiate the modification or dissolution of the order. The applicant has the burden of presenting evidence to substantiate the original findings. In practical terms, this means you need documented evidence — veterinary records, training certifications, witness statements, or photographic evidence of provocation — ready before you appear in court.
Pro Tip: Gather evidence immediately after any incident involving your dog. Photographs of the scene, written statements from witnesses, and veterinary records documenting the dog’s history can all be introduced at the court hearing and may significantly affect the outcome.
Maine also does not permit breed-based profiling as a substitute for individual behavioral assessment, which gives owners of breeds sometimes associated with aggression a fairer evidentiary footing. Compare this with how owners navigate the process in California or New York, where local ordinances can add layers of complexity.
What Happens After a Dog Is Declared Dangerous in Maine
A dangerous dog finding triggers mandatory penalties and a range of discretionary orders. The court does not have flexibility on the fine — it must be imposed — but has broad authority to shape the specific conditions placed on the dog and owner.
| Requirement Type | Details Under 7 MRS §3952-A |
|---|---|
| Fine | A fine of not less than $250 and not more than $5,000, plus costs, none of which may be suspended. |
| Secure Enclosure | A fence or structure of at least 6 feet in height suitable to prevent the entry of young children and to confine a dangerous dog. The enclosure must be locked and designed with secure top, bottom, and sides to prevent escape. |
| Muzzling Off-Premises | The court may order the dog to be muzzled whenever off the owner’s property. |
| Escape Notification | The court may order the owner or keeper to immediately notify the sheriff, a local law enforcement officer, or an animal control officer if the dog escapes. |
| Restitution | The court may order restitution in accordance with Title 17-A, chapter 54 for any damages inflicted upon a person or a person’s property by a dog determined to be a dangerous dog. |
| Lifetime Designation | Once a dog is declared dangerous, it will be considered a dangerous dog for its lifetime and will need to be licensed as such. |
| Euthanasia | The dog may be ordered to be muzzled, or euthanized if it has killed, maimed, or inflicted serious bodily injury upon a person or has a history of a prior assault. |
Beyond orders affecting the dangerous dog itself, the court may also require the owner to provide the local animal control officer with photographs and descriptions of any other dogs kept on the premises, including sex, breed, age, identifying markings, and microchip numbers. Those other dogs may also be subject to confinement orders. This is one of the more far-reaching aspects of Maine’s law — a single incident can affect every dog in your household.
All fines, other than costs, must be paid to the municipality where the dog resides and be placed in the municipality’s animal welfare account. The funds do not go to the complainant directly; they support local animal welfare services.

How to Contest a Dangerous Dog Declaration in Maine
Contesting the declaration means challenging it at the court hearing stage — or, if a pre-hearing interim order has been issued, moving to dissolve or modify that order before the main hearing takes place. Maine’s process is court-based, so your challenge is a formal legal proceeding with evidentiary standards.
The most effective defenses typically fall into one of these categories:
- Provocation: Demonstrating that the complaining party provoked the dog immediately before the incident, particularly if the incident occurred on your property.
- Trespass: Showing that the person or animal harmed was trespassing on your premises at the time of the injury, which removes the incident from the statutory definition of a dangerous dog under 7 MRS §3907(12-D).
- Insufficient Evidence: Challenging the factual basis of the complaint — for example, disputing whether the dog’s behavior would cause a “reasonable and prudent person” to fear imminent serious bodily injury.
- Law Enforcement Exemption: “Dangerous dog” does not include a dog certified by the State and used for law enforcement use.
- Identity of the Dog: Contesting whether your dog was actually the animal involved in the incident.
If the court has already issued a finding and you believe it was made in error, Maine’s standard appellate procedures apply. You would need to file a notice of appeal with the appropriate court within the statutory deadline. Consulting a Maine attorney who handles animal law or civil litigation is strongly advisable at this stage.
For nuisance dog findings specifically, after two years from the date of the court order finding that the dog is a nuisance dog, the owner or keeper may petition the court to amend or reduce any of the restrictions placed on the dog. The owner may petition to amend or reduce restrictions by demonstrating compliance and showing the dog no longer poses a risk. No equivalent petition pathway exists for dangerous dog designations — that label is permanent.

Penalties for Violating Dangerous Dog Requirements in Maine
Receiving a dangerous dog declaration is only the beginning of your legal obligations. Failing to comply with the court’s orders carries its own serious consequences — and Maine’s statute is written to escalate penalties when owners ignore their responsibilities.
If a dog whose owner refuses or neglects to comply with the order wounds any person by a sudden assault or wounds or kills any domestic animal, the owner shall pay the person injured treble damages and costs to be recovered by a civil action. Treble damages mean the court can award three times the actual damages to the injured party — a significant financial exposure for non-compliant owners.
Beyond civil liability, the court retains authority to escalate its orders. If the dog poses a continuing threat and the owner has not complied, the court may issue a warrant to the sheriff or any of the sheriff’s deputies or to a local law enforcement officer or constable in the municipality where the dog is found, commanding the officer to have the dog humanely euthanized within 14 days of the warrant date.
Additional penalties for non-compliance can include:
- Additional fines within the $250–$5,000 range per violation
- Seizure and impoundment of the dog at the owner’s expense
- The owner or keeper must be ordered to pay all costs of supplementary proceedings if enforcement action is required
- Potential ownership bans, which the court may impose as part of a dangerous dog finding (though not available for nuisance dog findings)
Important Note: Maine’s dangerous dog designation is permanent. Once a dog is declared dangerous, it will be considered a dangerous dog for its lifetime and will need to be licensed as such. There is no petition process to remove the dangerous dog label, unlike the nuisance dog designation, which can be revisited after two years of compliance.
If your dog has been involved in a serious incident and you want broader context on breed-related risk factors, our article on the most dangerous dog breeds provides behavioral background that may inform how you approach training and containment going forward. You can also compare Maine’s penalty structure with states like Missouri and Arizona to understand how enforcement approaches differ across the country.
Maine’s dangerous dog law is designed to protect the public while giving owners a meaningful opportunity to be heard. The process is court-driven, the standards are behavior-based rather than breed-based, and the penalties escalate sharply for owners who do not take their obligations seriously. If your dog is facing a complaint, act quickly, document everything, and seek qualified legal counsel before your hearing date.
