If you just adopted a puppy in Missoula or moved a family dog to Bozeman, you might assume a rabies tag from your vet covers you legally. It doesn’t. Dog tag laws in Montana are built around a separate license tag issued by your city or county, and the rules for getting one differ depending on which side of a city limit sign you live on.
This guide walks through what state law actually requires, how local ordinances fill in the gaps, and what happens if you skip the process altogether.
Important Note: This article explains general licensing patterns under Montana state law and common local ordinances. It is educational information, not legal advice. Confirm current fees, deadlines, and requirements with your specific city or county before relying on this guide.
Are Dog License Tags Required in Montana?
Montana does not run one statewide dog licensing program the way it does vehicle registration. Instead, state law hands the authority down to local government. Montana’s dog statutes are organized under Title 7, Chapter 23, with separate parts covering local government control of dogs, county control of dogs, municipal control of domestic animals, and required spaying or neutering of cats and dogs. Whether you’re legally required to license your dog depends entirely on whether your county or city has adopted an ordinance under those parts.
Once a local government does adopt a licensing ordinance, though, the tag requirement becomes real and enforceable. Any dog license tag issued annually by a municipal corporation under an ordinance that substantially complies with the relevant state law parts, and that requires the tag to be worn on the dog’s collar along with a record identifying the owner, satisfies the state licensing requirement. In practice, nearly every incorporated city and most counties in Montana have adopted some version of this ordinance, so licensing is the norm rather than the exception.
Three Types of Dog Tags (and Which Ones Montana Law Actually Means)
Dog owners often carry three different metal or plastic discs on a collar, and it’s easy to mix them up. The first is a rabies vaccination tag, issued by a veterinarian to show a current rabies shot. The second is a personal identification tag, usually engraved with the dog’s name and an owner’s phone number. Neither of these is what Montana’s dog tag laws are talking about.
The third is the municipal or county license tag, and that’s the one state and local law actually regulate. Local ordinances typically define a “license” as a metallic tag stamped with an identifying serial number, attached to the dog’s collar or harness, paired with a certificate carrying the same serial number along with the owner’s name, address, a description of the dog, and its rabies vaccination date. The license tag ties directly to a government record, which is why it carries legal weight that a name tag or rabies tag does not.
Dogs aren’t the only pets covered this way. Several Montana cities issue similar tags for cats, and you can find more detail on those rules in this guide to outdoor cat laws in Montana.
What Montana Law Says About Licensing Pet Dogs
The core state statute on tag-wearing is direct about what’s expected once a local ordinance is in place. It is unlawful, when a county licensing ordinance is in effect, for a dog not to wear a collar and tag identifying the dog and designating its owner. That single sentence is the legal backbone behind nearly every city and county licensing program you’ll encounter in the state.
The law also carves out a narrow, practical exception. It is lawful to remove the collar and license tag when the dog is under the immediate control of its owner or the owner’s agent. That means a dog undergoing grooming, a bath, or a supervised training session isn’t automatically in violation just because the collar came off for a few minutes.
Pro Tip: Keep your dog’s license certificate (not just the tag) somewhere accessible at home. If the tag falls off, the certificate number is what animal control or a vet clinic will ask for when confirming your dog’s license status.
Age, Rabies Proof, and When You Must License Your Dog in Montana
There’s no single statewide age cutoff for when a puppy needs a license. Instead, each city or county sets its own threshold. In Great Falls, for example, dogs and cats over four months of age must be registered and licensed, and owners are limited to two dogs and two cats over that age without a multiple animal permit. In the Town of Superior, the trigger is later: a person keeping, harboring, or maintaining a dog over six months of age must register and license the dog.
Rabies proof is the one constant across nearly every jurisdiction. To obtain a license in Great Falls, the owner must complete registration paperwork, pay the annual fee, and provide proof of rabies vaccination. Billings follows the same pattern, requiring proof of rabies vaccination and spay/neuter status for licensing. If your dog isn’t current on rabies shots yet, that’s the first box to check before you even think about the tag.

How and Where You Get a Dog License Tag in Montana
Where you go to license a dog depends on your city. In Billings, licenses can be purchased at the Animal Control Office or by mailing a completed licensing form, and they’re also sold at the animal shelter and several partner veterinarian clinics around the city. Great Falls takes a similar approach, letting owners obtain licenses through a local vet or the Animal Shelter.
Some smaller cities route the process through their county entirely. In Whitefish, every person who owns, keeps, or harbors a dog in the city must annually obtain a license from Flathead County under the county’s animal control ordinance. That’s a useful reminder to check with your county treasurer or animal control office if your city doesn’t run its own program. You’ll generally need the same three things no matter where you go: proof of current rabies vaccination, proof of spay/neuter status if applicable, and payment of the licensing fee.
Must Your Dog Wear the License Tag on Its Collar in Montana?
Yes, and local ordinances tend to treat this literally. In Superior, any dog found off the owner’s premises without a license tag is considered unlicensed even if a license has actually been issued for the dog. In other words, having paid for the license isn’t enough on paper if the tag itself isn’t on the collar when an officer checks.
Tags are also non-transferable between animals. License tags cannot be moved from one dog to another, and it’s unlawful to place a license tag on a dog for which it wasn’t issued. If you have multiple dogs, each one needs its own tag and its own paperwork. This ties closely into leash laws in Montana, since a dog off-leash and off-property without a visible tag is often the exact scenario animal control ordinances are written to catch.
Fees, Renewals, Spay/Neuter Discounts, and Exemptions in Montana
Licensing fees are set locally, and spay/neuter status almost always changes the price. The table below shows how a few Montana jurisdictions compare, based on published city and county information.
| Jurisdiction | License Term | Spayed/Neutered Fee | Unaltered Fee |
|---|---|---|---|
| Bozeman | Annual | $10 | $25 |
| Town of Superior | Annual or Lifetime | $5 (lifetime option) | $10 (annual) |
| Missoula County/City | 1, 2, or 3 years | Varies by age and altered status | Varies by age and altered status |
Bozeman charges $10 for dogs that are spayed or neutered and $25 for dogs that are not, a spread designed to nudge owners toward altering pets. Missoula gives owners more flexibility on timing: license fees there depend on the age of the dog and whether it’s spayed or neutered, and licenses can be purchased on an annual, two-year, or three-year basis.
Exemptions exist mainly for working and assistance dogs. Under Butte-Silver Bow County ordinance, license fees are waived for dogs trained to assist sight or hearing impaired persons while actually being used for that purpose, though the dogs must still obtain a license and still be vaccinated. A fee waiver isn’t the same as a licensing exemption; the paperwork still has to happen. If your household includes a working dog, it’s worth reviewing service dog laws in Montana alongside your local licensing ordinance to see which specific exemptions apply.
City and County Rules That Still Control in Montana
You might wonder why Montana doesn’t just standardize dog licensing statewide. The short answer is that the legislature deliberately left it to local governments. Montana does not have a statewide law limiting how many dogs a person may own, since those rules are set by individual cities and counties, and the same local-control pattern extends to licensing and kennel requirements.
This produces real variation from one town to the next. Billings residents can keep up to two dogs and two cats without a multiple-animal permit, and Bozeman has a similar rule requiring a kennel license once you exceed two of each. Bozeman goes a step further by folding other animals into the same licensing framework: city code requires all dogs, cats, and chickens to be licensed, and a kennel license is needed for more than two cats or two dogs. If backyard poultry is part of your household, it’s worth pairing your dog license research with this guide to backyard chicken laws in Montana.
Some cities also layer breed-specific ordinances on top of general licensing rules, which is worth checking if you own a dog covered by local restrictions like those outlined in this overview of American Bully laws in Montana. And because licensing sits inside the broader animal welfare framework, it’s connected to enforcement under animal cruelty laws in Montana in cases involving neglected or unvaccinated animals.
Lost Tags, Moving, and Replacing a License in Montana
A lost tag doesn’t cancel your dog’s license, but it does put you at risk of a citation if animal control can’t see proof on the collar. Most cities let you request a replacement tag from the same office that issued the original, typically for a small reissue fee, though you’ll usually need to show the original certificate or registration number.
Moving is a different story, because licenses generally don’t travel with you across city or county lines. Registrations for animals, like cars, are not transferable in most Montana municipalities, meaning a dog licensed in one city needs a fresh license after a move to another. If you’re relocating a pet into Montana from another state, that process runs alongside separate rules covered in this guide to pet import laws in Montana, which deal with health certificates and entry requirements rather than local licensing.
Penalties for Unlicensed Dogs in Montana
Penalties for skipping the license range from a citation to, in some counties, impoundment of the dog itself. Butte-Silver Bow County’s ordinance is blunt about it: it is unlawful for any person to keep, harbor, maintain, or feed a dog for which no current license has been obtained, or upon which no required tag has been placed and kept. The same ordinance backs that up with real enforcement teeth, since an animal control officer or law enforcement officer has the authority to seize and impound any dog not currently licensed and tagged, and to dispose of it as provided by the ordinance.
Missoula County frames noncompliance in similarly direct terms: failing to license your dog could result in a citation, so staying compliant isn’t just smart, it’s legally required. Beyond the fine itself, an unlicensed dog that bites someone or gets loose is harder to trace back to an owner, which can complicate matters under Montana’s strict-liability approach to dog bite incidents. If that’s a concern in your household, it’s worth reading up on dog bite laws in Montana for the fuller liability picture.
Common Mistake: Assuming a rabies tag counts as a license. Animal control officers in most Montana cities check specifically for the municipal or county license tag, not the vet-issued rabies tag, when confirming compliance.
How to Find Your Local Licensing Authority in Montana
Since licensing runs through city and county governments rather than a single state office, your first call should be local. In larger cities, that usually means the animal control department or city treasurer’s office, such as the City of Billings licensing office or the Missoula Public Health animal licensing program.
In smaller towns, the town clerk or a designated animal control officer often handles licensing directly, as seen with the Town of Superior’s animal control department. If you’re not sure whether your address falls under city or county jurisdiction, your county clerk and recorder’s office can point you to the right licensing authority, and most counties post current fee schedules and application forms online or at the courthouse.
Before you head in, gather your dog’s rabies certificate, spay/neuter documentation if applicable, and proof of address. Having those three items ready is usually enough to walk out with a tag the same day, whether you’re in Missoula, Bozeman, or a small county seat working from a paper ledger that’s been in use for decades.
