Maine has some of the most specific wolf-related statutes of any state in the Northeast, and if you are wondering whether you can keep a wolf as a pet here, the short answer is no. A pure wolf is explicitly listed among the species you cannot own in Maine, and the rules around wolf hybrids — animals that are part wolf and part domestic dog — are nearly as strict.
Understanding exactly where the law draws the line matters whether you are considering a wolfdog, researching wildlife regulations, or simply curious about what Maine allows. This article walks through the state’s statutes, permit requirements, local rules, and the penalties that apply when someone gets it wrong.

Is It Legal to Own a Wolf in Maine?
Owning a pure wolf in Maine is not legal for private residents. In Maine, a permit is required to own most wild birds or animals, and several species are not allowed at all — including bear, moose, wild turkey, deer, lion, cheetah, wolf, monkey, camel, alligator, monk parakeet, and swan. That list comes directly from the state’s wildlife possession framework, and wolves sit firmly on the prohibited side.
Wolf hybrids — animals bred from a wolf and a domestic dog — occupy a separate and more complicated legal category. They are not outright banned in the same way a pure wolf is, but except as provided by a narrow exception, a person may not keep a wolf hybrid in the state unless that person holds a valid permit to possess wildlife in captivity issued by the Department of Inland Fisheries and Wildlife under Title 12, section 12152.
In practice, that means new wolf hybrid ownership by private residents is effectively closed off. The permit pathway that remains is primarily designed for licensed wildlife facilities, not households. To understand why, you need to know how Maine defines these animals and what the law’s history looks like.

Wolves vs. Wolf Hybrids: How Maine Defines Them
Maine law treats pure wolves and wolf hybrids as legally distinct animals, and that distinction shapes everything else in this discussion. A pure wolf (Canis lupus) is classified as prohibited wildlife — full stop. No private ownership permit exists for one.
Wolf hybrids fall under a separate statutory definition. Under Maine Revised Statutes Title 7, section 3907, a “wolf hybrid” means a mammal that is the offspring of the reproduction between a species of wild canid or wild canid hybrid and a domestic dog or wild canid hybrid, and the definition also includes any mammal that is represented by its owner to be a wolf hybrid, coyote hybrid, coydog, or any other kind of wild canid hybrid.
That self-representation clause is notable. If you tell your town clerk or an animal control officer that your dog is a wolf hybrid, Maine law treats it as one — regardless of what a DNA test might show. The law defines a wolf hybrid as any canine that results from the interbreeding of a dog and wolf regardless of how many generations have passed since the interbreeding occurred, though in practice a canine is typically called a wolf hybrid only if there is specific crossbreeding with wolves.
The grey wolf is not the only species that can produce a regulated hybrid under this definition. Maine’s language covers all wild canids, which means animals like the eastern wolf and the Indian wolf would also fall within the statute’s scope if crossed with a domestic dog.
Key Distinction: A pure wolf cannot be privately owned in Maine under any permit. A wolf hybrid requires a state-issued wildlife possession permit — and the only remaining exception for keeping one as a pet applies solely to animals already licensed in 2011.
Maine’s Laws on Owning a Wolf or Wolf Hybrid
Maine’s wolf hybrid regulations have evolved significantly over the past three decades. Up until 1995, owning a wolf-dog hybrid was prohibited outright, but in that year Maine passed a law (Maine PL 1995 c. 409) to regulate wolf hybrids, which required the dogs to be licensed. That licensing framework remained in place for over a decade before the legislature tightened the rules again.
The major turning point came in 2011. According to the law enacted that year, future ownership of wolf hybrids is prohibited unless a person holds a valid permit to possess wildlife in captivity issued by the Maine Department of Inland Fisheries and Wildlife (MDIFW). The legislation was developed after legislators heard testimony that keeping wolf hybrids posed concerns for public safety and that the current regulation of wolf hybrid kennels did not provide adequate safeguards.
A narrow grandfather exception was written into the 2011 law. A person keeping a wolf hybrid as a pet and in compliance with all applicable provisions on June 1, 2011 may continue to keep that wolf hybrid as long as the wolf hybrid has been spayed or neutered and the owner continues to license the wolf hybrid in accordance with section 3922, subsection 3-B. This exception was designed to phase out private wolf hybrid ownership over time, not to create a new pathway for it.
Selling or exchanging a wolf hybrid for value is also prohibited. A wolf hybrid may not be sold or exchanged for value, and ownership may be transferred only in accordance with the specific provisions governing wolf hybrids found at large or those kept under the grandfather exception.
For context on the broader wolf family and why these animals raise public safety concerns, you can read about the interior Alaskan wolf and the Arabian wolf — two subspecies that illustrate the range of size and behavior across Canis lupus.
Permits and Requirements in Maine
Two separate permit systems govern wolf-related animals in Maine, administered by two different agencies. Knowing which one applies to your situation is essential.
Wildlife Possession Permit (Title 12, Section 12152) — This is the primary permit required to keep a wolf hybrid in Maine. A category 2 restricted species possession permit allows the holder to possess wildlife that requires special housing or care. Wolf hybrids fall into this category. The Commissioner of Inland Fisheries and Wildlife is required to establish confinement standards in rule that prevent escape of a wolf hybrid and restrict unauthorized humans from having contact with a wolf hybrid kept under such a permit.
Permanent Identification Requirement — Any wolf hybrid kept under a permit or under the 2011 grandfather exception must be permanently identified. The commissioner adopts rules to establish methods of identifying wolf hybrids through tattooing, the placement of a microchip under the animal’s skin, or any other method determined by the commissioner as adequately providing a permanent means of identification on the body of the animal.
Municipal Licensing — Beyond the state permit, wolf hybrids also require a local license. The law requires wolf hybrid owners to license their animals in the town where they reside, as well as requiring that those animals be vaccinated for rabies and permanently identified. However, there is a nuance on the rabies vaccine: the original law included a vaccination requirement, but it was removed due to uncertainty about the vaccine’s effectiveness on wolf hybrids, which might give a false sense of protection.
The table below summarizes the key requirements that apply to each animal category in Maine:
| Animal | Private Ownership Allowed? | Permit Required | Spay/Neuter Required | Permanent ID Required |
|---|---|---|---|---|
| Pure Wolf | No | N/A (prohibited) | N/A | N/A |
| Wolf Hybrid (new acquisition) | Only with wildlife possession permit | Yes — Title 12, §12152 | Yes | Yes — microchip or tattoo |
| Wolf Hybrid (pre-2011 grandfather) | Yes, under strict conditions | Municipal license required | Yes | Yes — microchip or tattoo |
The Department of Agriculture maintains a list of persons who own licensed wolf hybrids and updates it annually to account for animals that have died or been transferred. The law requires the owner of a wolf hybrid to report the death of that animal to the Department within 30 days and to report any transfer within 10 days.
If you are interested in large, wolf-like dog breeds that do not trigger these regulations, the difference between the Scottish Deerhound and Irish Wolfhound is worth reading — both breeds carry the “wolf” name but are fully domestic dogs with no special permit requirements in Maine.
Local Laws That May Apply in Maine
State law sets the floor, but Maine municipalities can go further. Local governments often set their own rules, meaning ownership can still be restricted or banned at the county or city level, and in many states, counties, cities, and towns make it illegal to own a wolf dog even where state law allows it. Maine is no exception to this pattern.
If you live in a city or town with its own animal control ordinance, that ordinance may prohibit keeping any wolf hybrid — or any animal resembling one — regardless of what permits the state has issued. Portland, Bangor, and other larger Maine municipalities have broad animal control codes that give local officers significant discretion.
Homeowners association rules and rental lease agreements can also restrict exotic or wolf-type animals independently of government law. These private restrictions are enforceable even if you hold every required state and local permit.
Rules often vary based on the wolf content of the animal, with higher-percentage hybrids subject to tighter restrictions, and local governments may impose additional limits or bans. If you are researching this for a specific Maine address, contacting your municipal clerk or town manager directly is the most reliable way to find out what local ordinances apply.
Pro Tip: Before acquiring any wolf hybrid under a state permit, call your town or city clerk to confirm whether a local ordinance restricts or bans such animals. State approval does not override a stricter local rule.

Penalties for Illegal Wolf Ownership in Maine
Maine does not treat violations of its wolf and wolf hybrid laws lightly. The penalties span civil fines, animal seizure, and in some cases the euthanasia of the animal itself.
Civil fine for keeping a wolf hybrid without authorization: A person who violates the wolf hybrid possession statute commits a civil violation for which a fine of $2,500 may be adjudged. This applies to anyone keeping a wolf hybrid without the required permit or outside the narrow grandfather exception.
Civil fine for abandonment: A person who abandons a wolf hybrid licensed under section 3922 commits a civil violation for which a forfeiture fine not to exceed $1,000 may be adjudged, while a person who abandons a wolf hybrid not licensed under section 3922 commits a civil violation for which a fine of $1,000 must be adjudged and may also be subject to a penalty under Title 12, section 12153.
Wolf hybrid found at large: The owner or keeper of a wolf hybrid found at large commits a civil violation, and an animal control officer shall seize, impound, or restrain the animal. If the owner cannot be located, the animal goes to a designated shelter. Upon expiration of a 6-day period, ownership of the wolf hybrid is vested in the animal shelter. The shelter’s options are then limited: it can transfer the animal to a licensed wildlife permit holder, transfer it to an out-of-state refuge licensed to accept wolf hybrids, or — after 8 days — euthanize it.
An animal shelter may not sell, give away, or offer for adoption a wolf hybrid — so unlike a stray dog, a seized wolf hybrid has no path to a new private home through normal shelter adoption.
Beyond financial penalties, illegal possession can also result in the loss of the animal and potential involvement of the Maine Department of Inland Fisheries and Wildlife, which has authority over wildlife violations under Title 12. Repeat or egregious violations can escalate from civil to criminal territory under Maine’s broader wildlife statutes.
For those who love wolves from a distance, learning about related species is a rewarding alternative. The Ethiopian wolf and the Iberian wolf are among the world’s rarest canids and make for fascinating reading without any legal complications. The Himalayan wolf and the aardwolf round out a picture of just how diverse the broader wolf and canid family really is.
Maine’s laws on this topic reflect a deliberate policy choice: the state has moved steadily toward phasing out private wolf hybrid ownership while maintaining a permit pathway for licensed wildlife facilities. If you are a Maine resident with a genuine interest in wolves, supporting a licensed wildlife sanctuary or rehabilitation center is the most legally sound — and arguably the most meaningful — way to stay connected to these animals.
