Traveling with Pets to New Hampshire: Entry Rules, Health Certificates, and Rabies Proof You Need
October 15, 2026
If you’re loading the car or booking a flight for a trip to the White Mountains or the Seacoast, traveling with pets to New Hampshire comes with a short but non-negotiable paperwork list. New Hampshire’s rabies law does not carve out an exception for lap dogs or indoor-only cats — vaccination is required by law in New Hampshire for dogs, cats, and ferrets 3 months of age and older, even if they stay indoors.
That single fact surprises a lot of pet owners who assume “he never goes outside” is a valid excuse. Below is what New Hampshire actually checks for, who checks it, and how to get your paperwork in order before you leave the driveway.
What It Covers (and What It Doesn’t)
This guide covers the legal entry requirements for personally owned dogs and cats crossing into New Hampshire by car or by air: rabies vaccination proof, the certificate of veterinary inspection (CVI), and the local licensing rules that kick in once you’ve arrived. It also flags where airline paperwork rules and state import rules diverge, since travelers often assume they’re the same thing.
It does not cover commercial breeder or shelter transfers, which fall under a separate Official Certificate of Transfer process, nor does it cover international pet entry, livestock, or full exotic-species import law. If you’re traveling with young kids and a low-key companion animal rather than a dog or cat, our guide to low-maintenance pets for kids covers species that typically carry fewer travel restrictions altogether.
Who Sets Entry Rules When You Bring a Dog or Cat into New Hampshire
Pet entry rules in New Hampshire come from a mix of state statute and administrative code, not a single agency. The New Hampshire Department of Agriculture, Markets, and Food — specifically its Division of Animal Industry — writes and enforces the day-to-day import regulations under Agr 2100 and Agr 2112, working through the office of the state veterinarian.
Two statutes sit above those rules: RSA 436 governs rabies vaccination, and RSA 437 governs health certificates tied to the sale or transfer of dogs, cats, and ferrets. The NH Department of Agriculture’s electronic animal health records program is where licensed veterinarians file the paperwork that makes transfers official. Once you’re in-state, a third layer takes over: your local city or town clerk, who handles dog licensing and keeps rabies records on file for animal control purposes.
Dogs vs. Cats: Do Entry Rules Differ?
At the border, no — the entry rule is the same for both species. Under New Hampshire’s administrative code, dogs and cats shall not enter the state of New Hampshire from an area under quarantine for rabies, and every dog and cat 3 months of age and older at the time it enters the state shall be vaccinated against rabies. That rule applies equally to the domestic dog (Canis lupus familiaris) and the domestic cat (Felis catus), with no species-specific carve-out at the state import level.
Where dogs and cats part ways is after you’ve arrived. New Hampshire requires annual municipal licensing for dogs but not for cats. If you’re traveling with a mixed household — say a dog and a cat who already share a crate on road trips — our guide to dog breeds that are good with cats is a useful side reference for planning shared travel logistics, even though it won’t change the paperwork either animal needs.
| Requirement | Dogs | Cats |
|---|---|---|
| Rabies vaccination at entry (3+ months old) | Required | Required |
| CVI / health certificate | Required | Required |
| Cannot enter from a rabies-quarantined area | Applies | Applies |
| Municipal licensing after arrival | Required, must be licensed by owners in the town or city of residence with proof of rabies vaccination | Generally not required to be licensed by New Hampshire municipalities |
Rabies Vaccination Proof You Need
Rabies is the one vaccine New Hampshire actually mandates by law, and the state is strict about it. Under RSA 436:100, every dog, cat, and ferret 3 months of age and older shall be vaccinated against rabies, and young dogs, cats, and ferrets shall be vaccinated within 30 days after they have reached 3 months of age. If you’re bringing an already-owned pet across the border rather than adopting one locally, the entry-specific version of that rule is what matters: every dog and cat 3 months of age and older at the time it enters the state shall be vaccinated against rabies, and every dog and cat under 3 months of age at the time it enters the state shall be vaccinated within 30 days after they have reached 3 months of age.
The vaccine itself has to meet a specific standard, too — dogs and cats shall be vaccinated with rabies vaccine licensed by the United States Department of Agriculture. A farm-store vaccine you administer yourself won’t satisfy that requirement; it has to come from a licensed veterinarian.
Key Insight: A rabies tag on the collar is not proof by itself. What matters is the written certificate from the vet showing the vaccine brand, lot number, and expiration date — the same document a licensing clerk or animal control officer will ask to see.
Boosters follow a set schedule after the first dose. New Hampshire law requires that every dog, cat, and ferret shall be revaccinated between 9 and 12 months after the initial vaccination and subsequently receive booster vaccines as outlined in the most current National Association of State Public Health Veterinarians’ Compendium of Animal Rabies Prevention and Control. For a deeper breakdown of exemption rules and enforcement, our companion piece on rabies vaccine requirements in New Hampshire walks through the medical exemption process in more detail.
Does New Hampshire Require a CVI / Health Certificate?
Yes, but it’s worth separating two documents that sound similar and often get confused. The first is a general Certificate of Veterinary Inspection (CVI), sometimes just called a health certificate, required for any dog, cat, or ferret brought into the state. Under the state’s importation rule, animals must be inoculated against common canine and feline viral diseases within one year, but not less than 7 days, before entry, and accompanied by a CVI issued by an accredited veterinarian.
The second document, the Official Certificate of Transfer (OCT), only applies when ownership of the animal is changing hands inside New Hampshire — an adoption, purchase, or rescue placement. The StateVet Portal is the vehicle for creating Official Certificates of Transfer, a document required for the transfer of dogs, cats and ferrets to the public in New Hampshire, and an OCT shall be created in the StateVet Portal by a New Hampshire licensed veterinarian for each dog, cat or ferret transferred from one owner to another. If you’re simply visiting or relocating with a pet you already own, the OCT generally does not apply to you — the CVI does.
| Document | Who Needs It | Issued By |
|---|---|---|
| CVI / Health Certificate | Any dog, cat, or ferret entering New Hampshire | Accredited or licensed veterinarian |
| Official Certificate of Transfer (OCT) | Animals changing ownership within New Hampshire | New Hampshire-licensed veterinarian, filed via StateVet Portal |
The state agriculture department summarizes the CVI requirement plainly: dogs and cats 3 months of age and older, at the time it enters the state, shall be vaccinated for rabies, with the CVI serving as the paper trail proving it. Our broader look at pet import laws in New Hampshire covers what the CVI form itself has to contain in more detail.
Other Papers, Tests, or Permits (HI: quarantine / FAVN / AQS-279)
If you’ve researched pet travel to Hawaii, you’ve likely run into mandatory quarantine periods, FAVN rabies titer tests, and AQS-279 import permits. None of that applies here. New Hampshire has no general quarantine requirement, no titer test, and no equivalent of AQS-279 for domestic dogs and cats arriving with proof of rabies vaccination and a valid CVI.
Important Note: The lighter paperwork load in New Hampshire compared to island states like Hawaii is intentional — it reflects the difference between an island ecosystem trying to stay rabies-free and a mainland state managing an endemic wildlife reservoir instead.
A few narrower situations do trigger extra steps. Rescue organizations importing dogs from areas with documented high rabies risk sometimes route animals through a dedicated quarantine program rather than a standard CVI; Canine Quarantine NH outlines that process for transporters and fosters, and notes that the pet must be found free of contagious disease prior to transport. Pet birds face their own add-on: there are additional requirements for birds customarily used as household pets; they must be accompanied by a CVI, and a permit issued by the department prior to importation. And regardless of species or age, no person, firm, corporation, or other entity shall ship or bring into the state of New Hampshire, to offer for transfer in the state of New Hampshire, any cat, dog, or ferret less than 8 weeks of age. If your household travels with something outside the dog-and-cat norm — a rabbit, a chameleon, or another small exotic — check the species-specific rules under Agr 2100 before you pack; our guides to rabbit breeds to keep as pets and chameleons to keep as pets are useful starting points for care needs, though you’ll still want to confirm import specifics separately.
Flying vs. Driving: Airline Health Certificates Are a Separate Layer
Most travelers reach New Hampshire by car, and driving across the border comes with no checkpoint inspection — no one stops you at the state line to check your dog’s paperwork. That said, you still need the CVI and rabies certificate on hand, because hotels, boarding kennels, veterinary clinics, and animal control can all ask for it, and having it ready avoids a scramble later.
Flying is a different story entirely. Airlines set their own health certificate rules independent of state import law, often on a tighter timeline than New Hampshire’s CVI window, and gate staff will check that paperwork before your pet boards. Treat the state’s CVI requirement and your airline’s certificate requirement as two separate boxes to check — meeting one does not automatically satisfy the other. If your trip involves international connections at any point, the APHIS Pet Travel website is where a USDA-accredited veterinarian can address destination-country entry requirements, including vaccinations, tests, or treatments, and the issuance of health certificates.
Pre-Trip Checklist
Getting the paperwork right comes down to timing more than complexity. Work through these steps in order, starting several weeks before departure if your pet’s rabies status is not current:
- Confirm rabies vaccination status first. If your pet needs a first dose or a booster, schedule it with a licensed veterinarian well before your trip.
- Request the written rabies certificate, not just the tag. Ask your vet for the document showing vaccine brand, lot number, and expiration date.
- Schedule the CVI close to your travel date. Have your veterinarian issue the certificate of veterinary inspection within the window New Hampshire and your airline (if flying) require.
- Pack physical and digital copies of both documents. Keep one set in the car or carry-on and a backup photo on your phone.
- Plan feeding and water stops for the drive. Pets handle missed meals differently than people do; our breakdown of how long dogs can go without food is worth a read if road delays might push back a regular feeding.
- Never leave a pet unattended in a parked car during rest stops, even briefly — our guide on leaving pets in hot cars in New Hampshire explains why this is both dangerous and, in many circumstances, against the law.
- If you’re relocating, note your new town or city clerk’s contact information. You’ll need it for licensing within 30 days of arrival.
Pro Tip: Book your pre-travel vet appointment as soon as you book your trip. CVIs and rabies boosters both have limited validity windows, and waiting until the week before travel leaves little room for a vet’s scheduling backlog.
What Happens If Your Pet Doesn’t Meet Entry Rules
The consequences differ depending on how you’re traveling and what you’re missing. If you’re flying, an incomplete or outdated health certificate typically means the airline denies boarding at the gate — there’s rarely a workaround once you’re at the counter, so this is not a risk worth taking with a non-refundable ticket.
If you’re driving, enforcement is less immediate but not absent. Should your pet be involved in an incident that draws animal control attention — a bite is the clearest example — New Hampshire Revised Statute §437:15 requires reporting bites to local health officer within 24 hours, and an owner who can’t produce current rabies proof at that point faces a far more complicated situation, potentially including mandatory quarantine of the animal. Separately, anyone who transfers a dog, cat, or ferret in the state without the proper certificate can run into direct statutory penalties under RSA 437:8. And if New Hampshire ever faces a documented disease outbreak, standard import exceptions can be pulled entirely: in the event of documented animal health risks, the relevant exceptions shall be suspended by written order of the commissioner, meaning the baseline rules described here could tighten with little notice.
After You Arrive: Local Licensing and Ongoing Rabies Rules
Getting across the border is only half the compliance picture — New Hampshire also expects new residents to register their dogs locally, and fairly quickly. Under RSA 466:1, every owner or keeper of a dog four months old or older shall annually cause it to be registered, numbered, described, and licensed in the office of the clerk of the city or town in which the dog is kept. Most municipalities apply the same 30-day window to newcomers that Dover spells out directly: new residents are required to license their dog(s) within 30 days after moving into town.
You’ll need the rabies certificate on hand for that visit — clerks won’t issue a license without it. Licenses run on a fixed calendar regardless of when you obtain one: the license shall be effective from May 1 to April 30 of the subsequent year. Miss the deadline and there’s a real cost attached: RSA 466:14 requires the clerk of the city or town to issue a $25 civil forfeiture to the owner or keeper of each unlicensed dog. Cats, as noted earlier, skip this step entirely at the municipal level.
Ongoing compliance doesn’t stop at licensing, either. Your pet’s rabies protection needs to stay current for as long as you live in the state, following the same booster interval — 9 to 12 months after the initial dose, then per the vaccine label going forward.

Where to Verify Current Rules
Regulations get amended, and administrative code sections get renumbered, so treat everything above as a starting point rather than a final word before you travel. The most reliable sources to check directly are:
- The New Hampshire Department of Agriculture, Markets, and Food — Division of Animal Industry, for CVI and import rule updates
- The full statutory text of RSA 437:8, covering health certificates for dogs, cats, and ferrets
- The administrative code text of Agr 2112.02, covering rabies vaccination at entry
- The New Hampshire Department of Health and Human Services zoonotic disease and rabies program page
- Your destination town or city clerk’s office directly, such as Concord’s dog licensing page, for local licensing specifics and current fees
Important Note: This article summarizes New Hampshire’s pet entry framework as of publication and is not a substitute for direct confirmation with the state veterinarian’s office, your airline, or your destination municipality. Vaccine timing rules, fees, and permit requirements can change, and a quick call before a long trip costs far less than a denied boarding or a missed license deadline.
