Maine’s dog breeding laws shifted significantly when Public Law Chapter 414 (LD 1771) took effect on September 24, 2025. The law shifts kennel licensing authority from local municipalities to the state’s Department of Agriculture, Conservation and Forestry, creating a significant change in how dog kennels — including hobby operations — are regulated statewide. If you keep five or more dogs in Maine, those changes almost certainly apply to you.
Whether you run a small hobby kennel in Aroostook County or a larger breeding operation closer to Portland, understanding your obligations under both state and federal law protects you from fines, forced closures, and license revocations. This guide walks through every layer of Maine’s breeding regulations so you know exactly where you stand.
Who Is Considered a Commercial Dog Breeder in Maine
Under Maine law, a “breeding kennel” means a location where five or more adult female dogs or cats capable of breeding are kept and some or all of the offspring are offered for sale, sold, or exchanged for value — or a location where more than 16 dogs or cats raised on the premises are sold to the public in a 12-month period. That definition casts a wide net, and it applies to hobby breeders just as it does to large commercial operations.
More broadly, a “kennel” means five or more dogs kept in a single location under one ownership for breeding, hunting, show, training, field trials, sledding, competition, or exhibition purposes. If you keep working dogs for hunting or mushing and hit that five-dog threshold, you now fall under state facility standards.
The sale or exchange of one litter of puppies within a 12-month period alone does not constitute the operation of a kennel. That single-litter exemption gives small-scale breeders some room, but it has firm limits — sell more than one litter or keep five or more breeding females and the exemption no longer applies.
Important Note: Before LD 1771 took effect in September 2025, hobby kennel owners with five or more working dogs could obtain a simpler municipal license from their local town office. The new law eliminates that option — there is no municipal license going forward, and anyone with five or more dogs is now classified as a kennel facility under state oversight.
If you breed dogs in Maine and sell more than one litter per year or maintain five or more adult females capable of breeding, you are operating a breeding kennel under state law. That classification triggers licensing, facility, inspection, and recordkeeping requirements described in the sections below.

Do You Need a License to Breed Dogs in Maine
A person maintaining a breeding kennel, as defined in section 3907, must obtain a license from the department and is subject to rules adopted by the department. There are no exemptions for small commercial operations once you cross the five-female threshold.
Anyone keeping fewer than five breeding-age females does not need a state breeding kennel license but must still comply with individual dog licensing requirements through their municipality. Individuals who sell or exchange one litter of puppies within a 12-month period are not considered to be operating a breeding kennel under state law. Anyone keeping fewer than five breeding-age females does not need a state breeding kennel license but must still comply with individual dog licensing requirements through their municipality.
Maine organizes breeding kennel licenses into three categories based on the number of breeding females you maintain. The fee structure, as set by the Maine Legislature under Public Law 2025, Chapter 414, is:
- Category 1: A breeding kennel that maintains at least 5 but no more than 10 female dogs or cats capable of breeding. License fee: $125.
- Category 2: A breeding kennel that maintains at least 11 but no more than 20 female dogs or cats capable of breeding. License fee: $150.
- Category 3: A breeding kennel that maintains 21 or more female dogs or cats capable of breeding. License fee: $200.
The license expires 12 months after the date of issuance. Annual renewal is required to stay in compliance. You should also be aware of related local rules — Maine’s kennel zoning laws can affect whether your licensed operation is actually permitted to run in your specific zone.
If you sell dogs and do not hold a breeding kennel license, a separate vendor’s license requirement may apply. A person not in possession of a valid license for an animal shelter, kennel, breeding kennel, boarding kennel, or grandfathered pet shop must obtain a vendor’s license under section 4163 prior to selling, offering for sale, or exchanging for value a cat or dog.
How to Get a Dog Breeder License in Maine
Applications for breeding kennel licenses are submitted directly to the Maine Department of Agriculture, Conservation and Forestry’s Animal Welfare Program. Previously, kennels were licensed through municipal governments, but LD 1771 centralized this process at the state level beginning in the 2025-2026 licensing period.
Applicants must provide documentation about their facility, the number of breeding animals, and compliance with animal welfare standards. You will also need to identify the person responsible for maintaining the license and operating the facility. All facilities licensed under these rules must provide the department the name and contact information of the person responsible for maintaining the license and operation of the facility. This person must be a current resident of the State of Maine and not be disqualified from facility licensure under 7 M.R.S.A. § 3935 (License Prohibited).
An applicant for a breeding kennel license shall state in the application the number of female dogs or cats capable of breeding that are maintained at the breeding kennel. This count determines your category and your fee.
New kennels that do not yet hold a valid license receive a conditional license while awaiting inspection. This temporary license allows new kennels to operate while awaiting a full inspection from the department. During the inspection process, the kennel must meet Maine’s minimum standards for animal welfare and facility operation. If any issues are found during the inspection, the kennel is given six months to rectify these problems. Failure to meet the required standards within this timeframe can lead to the suspension or revocation of the conditional license.
Once licensed, you must display your license number in all advertising. A breeding kennel shall prominently display in any advertising the state-issued kennel license number. The breeding kennel shall provide its license number to a person purchasing or receiving an animal from the breeding kennel. This transparency requirement applies to online listings, print ads, and any other marketing material.
Pro Tip: Maine law prohibits selling or giving away any puppy until it reaches eight weeks of age. It is unlawful for any person to sell, adopt, or give away any dog (puppy) or cat (kitten) until the eighth week of life. Build this timeline into your sales process to avoid violations.
Facility, Care, and Housing Standards for Breeders in Maine
Breeding kennels in Maine must follow a range of regulatory standards set by the Department of Agriculture, Conservation, and Forestry. These requirements address the basic care and housing of dogs, including provisions for clean living conditions, disease prevention measures, and adequate shelter. These standards apply whether you run a small home-based operation or a large commercial facility.
The facility will be inspected before a license is issued to ensure compliance with commercial facility standards, including ventilation, lighting, drainage, waste disposal, fire safety equipment, isolation areas, and structural regulations. Meeting these standards before you apply saves time and avoids the conditional-license process.
Below is a summary of key structural and care requirements under Maine Administrative Code Chapter 701:
| Requirement Area | Standard |
|---|---|
| Enclosure structure | Housing facilities must be structurally sound and maintained in good repair to protect the animal from injury and to contain the animal. |
| Flooring and bedding | All cages/pens must have a clean dry place for the animal to lie down and the flooring must be an impervious surface without perforations. There must be clean and sufficient bedding material to retain the animal’s normal body heat. |
| Neonatal temperature | Areas housing puppies from birth to two weeks old must be kept at a high enough ambient temperature to maintain their normal internal temperature. |
| Annual veterinary care | Animals used for breeding shall receive an annual health check-up from the veterinarian of reference each calendar year. |
| Sanitation and waste | Regular sanitation protocols must be followed, especially for waste management and food and water containers. |
| Utilities | All facilities must be properly licensed to operate legally and meet specific structural and care standards, including having reliable utilities like water and electricity, maintaining clean and secure enclosures, and ensuring animals are housed in safe, climate-appropriate conditions. |
You also need to plan for disease containment. Isolation areas must be provided and used for all animals being imported from out of state to ensure their health at the time of adoption in accordance with rules set forth in Chapter 216 “Rules Governing the Sale of Dogs and Cats and Importation of Dogs and Cats for Resale or Adoption.”
Zoning adds another layer of complexity. Someone who keeps dogs for hunting, showing, or mushing can suddenly find themselves classified as a facility, and sometimes as a facility, there is a conflict with zoning. A facility is often considered a business or commercial operation, and that is not always compatible with residential zoning. Check your local zoning ordinances before building or expanding your facility. Maine’s kennel zoning laws article covers this topic in detail.
Inspections and Recordkeeping Requirements in Maine
Maine’s Animal Welfare Program conducts inspections to verify that licensed facilities stay in compliance. Authorized agents of the Animal Welfare Program must at all reasonable times be allowed access to the physical premises and the records maintained by any pet shop, shelter, kennel, and boarding kennel. You cannot refuse entry to an authorized inspector.
Inspections happen before a license is initially issued and can occur on an ongoing basis. The department is directed to issue a written notice when a licensed facility fails inspection. The notice must describe the violation and corrective action needed. The department is also directed to charge a fee when more than two inspections are required to ensure that the corrective actions have been taken.
Recordkeeping is equally important. Animal shelters, kennels, breeding kennels, boarding kennels, and pet shops engaged in buying or selling animals shall keep records of the buyer and seller in each transaction for a two-year period commencing at the time of purchase or sale. The records must be open to inspection by the department or law enforcement officers.
Maine’s Chapter 701 regulations spell out exactly what those records must contain. Each pet shop, shelter, kennel, and boarding kennel must make and maintain for at least two years the following records: Official Certificates of Veterinary Inspection (CVI) as required by state statute and rule; the name and address of the person(s) from whom the animal was received; and the name and address of the person(s) receiving or buying the animal. Vaccination records, wellness exam documentation, and pharmaceutical logs are also required.
Pro Tip: Keep your records organized and immediately accessible. Inspectors can arrive without advance notice, and being unable to produce required documentation during an inspection is itself a violation — even if your animals are in perfect condition.
Quarantine situations require rapid action. When a licensed veterinarian, not employed by the state, quarantines a pet shop, shelter, kennel, or boarding kennel, both the veterinarian and the holder of the license must immediately notify the Animal Welfare Program. Immediate notification may be oral, but a written confirmation must be sent to the Animal Welfare Program within twenty-four hours.
Maine’s pet vaccination laws intersect with your recordkeeping obligations — rabies vaccination documentation is a required part of your facility records and must be current for every dog on the premises.
Federal Breeder Requirements That Apply in Maine
State licensing is not the only compliance layer Maine breeders face. The federal Animal Welfare Act, enforced by the USDA’s Animal and Plant Health Inspection Service (APHIS), adds a separate set of requirements for breeders who sell dogs commercially.
The USDA requires a federal license under the Animal Welfare Act for anyone who maintains more than four breeding females and sells dogs sight-unseen — online, by phone, or by mail. This regulation is enforced by APHIS (Animal and Plant Health Inspection Service). If you sell puppies through a website or ship them without buyers physically seeing the dogs first, federal licensing likely applies to you.
Small breeders with four or fewer breeding females are exempt, as are those who sell only face-to-face directly to the public. If all of your sales happen in person at your facility, you may not need a federal license even if you hold a Maine state breeding kennel license.
Under the USDA rule, the seller, the buyer, and the animal must all be physically present in the same location so the buyer can personally observe the dog before purchasing it. Selling a puppy after a video call does not satisfy this requirement — the buyer must see the dog in person.
The federal licensing process follows a structured path:
- Apply through USDA APHIS — Submit your application and pay the licensing fee.
- Pre-license inspection — An APHIS inspector will visit your facility to verify it meets all Animal Welfare Act standards. You must pass before your license is granted.
- Receive your license — Since 2023, all licenses are valid for three years and must be renewed before expiration.
- Ongoing unannounced inspections — USDA-licensed facilities are subject to unannounced inspections by APHIS.
Since 2023, USDA animal welfare licenses use a simplified flat fee structure: all licenses are now three-year licenses with a flat processing fee of $120. Federal recordkeeping requirements also apply alongside Maine’s state requirements. USDA-licensed breeders must keep detailed records for every dog they buy, sell, or transport. Records must be kept for at least one year after you no longer have the animal and must be available for inspectors during business hours.

Penalties for Violating Dog Breeding Laws in Maine
Maine takes unlicensed breeding operations seriously, and the enforcement tools available to the state are substantial. Operating a kennel without the required state license is a serious violation of Maine law, and the consequences range from civil fines to criminal charges, and they can compound quickly if violations go unaddressed.
Violations may result in civil penalties, license suspension or revocation, and potential criminal charges for animal cruelty under Maine Revised Statutes Title 17, Chapter 42. Civil penalties are assessed per violation, and the enforcement structure makes repeat or ongoing violations especially costly.
Civil penalties are assessed per violation, and each day of continued unlicensed operation can be treated as a separate violation under Maine enforcement practice. A facility that operates unlicensed for 30 days could face 30 separate civil penalty counts.
The state has several enforcement tools at its disposal:
- Civil fines — Monetary penalties can be imposed on any individual or facility found operating without a valid license. These fines are designed to discourage unlicensed breeding activities and ensure that all breeders comply with the state’s regulations.
- License suspension or revocation — If a violation is found to exist, the Animal Welfare Program or the Attorney General may seek enforcement remedies including but not limited to revocation or suspension of the license.
- Forced closure — In cases of severe non-compliance, the state has the authority to close breeding facilities that are operating without a license. This step is taken to protect animal welfare and to prevent irresponsible breeding practices.
- Court action — The commissioner may authorize certified humane agents or a certified state veterinarian to represent the department in District Court in the prosecution of civil violations. A certified humane agent or a certified state veterinarian may seek civil penalties as provided by law as well as a permanent or temporary injunction, restraining order, or other equitable relief as the court finds appropriate.
Federal violations carry their own separate consequences. Violating the Animal Welfare Act can result in serious consequences, and all enforcement actions and inspection reports are public record. A public enforcement record can damage your reputation with buyers and breed registries well beyond any financial penalty.
Municipalities may also enforce local ordinances related to the number of dogs kept at residences; for example, some cities limit dog ownership to four dogs over six months of age per residence. Local limits can effectively prevent you from operating a licensed breeding kennel in certain residential zones even if you have a valid state license.
If you breed or own dogs in Maine, staying current on related regulations helps you avoid inadvertent violations. Maine’s dog leash laws and pit bull laws apply to all dog owners, including licensed breeders. Breeders who also keep other animals on their property should review Maine’s goat ownership laws and backyard chicken laws to make sure the full operation stays compliant. You can also compare Maine’s framework against dog breeding laws in Minnesota or dog breeding laws in Texas to understand how other states approach similar issues.
Maine’s breeding regulations exist to protect dogs, buyers, and responsible breeders alike. Getting licensed before you need to — rather than after an inspection or complaint — is always the lower-risk path. Contact the Maine Department of Agriculture, Conservation and Forestry’s Animal Welfare Program directly for current application forms and guidance specific to your operation.
