Rabies Vaccine Requirements in New Hampshire: What Pet Owners Must Know

New Hampshire takes rabies prevention seriously, and the law reflects that. If you own a dog, cat, or ferret in the Granite State, you are not simply encouraged to vaccinate — you are required to by statute. Vaccination is required by law in New Hampshire for dogs, cats, and ferrets 3 months of age and older, even if they stay indoors.

Understanding exactly what the law demands — and what happens when it is not followed — can save you from costly consequences. This article walks through every major aspect of New Hampshire’s rabies vaccine requirements, from the animals covered and the vaccination schedule to exemptions, exposure protocols, and penalties.

Are Rabies Vaccines Required by Law in New Hampshire?

Yes, rabies vaccination is a legal obligation in New Hampshire, not a recommendation. Under RSA 436:100, every dog, cat, and ferret 3 months of age and older shall be vaccinated against rabies, and young animals shall be vaccinated within 30 days after they have reached 3 months of age.

The law applies regardless of whether your pet lives indoors, outdoors, or both. There is no lifestyle exception for house pets that never encounter other animals. There is no cure for rabies, which can be passed from animals to humans and is “virtually 100% fatal” once symptoms appear, according to the World Health Organization. That public health reality is exactly why New Hampshire has maintained a strict mandatory vaccination framework for decades.

Assistant State Veterinarian Nathan Harvey has attributed the absence of human rabies deaths in New Hampshire in recent history to the success of the state’s vaccine program. Keeping your pet current on its rabies vaccine is one of the most direct ways you contribute to that outcome.

Pro Tip: Dog owners in New Hampshire must show proof of rabies vaccination before a dog license will be issued. Per RSA 466, the owner or keeper of a dog must furnish to the town clerk verification from a licensed veterinarian that the dog has been vaccinated against rabies in accordance with RSA 436.

Which Animals Must Be Vaccinated Against Rabies in New Hampshire?

Under RSA 436:100, every dog, cat, and ferret 3 months of age and older shall be vaccinated against rabies. These are the only three species covered by the state’s mandatory vaccination statute. Other domestic animals — horses, livestock, rabbits, and exotic pets — are not subject to the same legal mandate, though veterinarians may recommend vaccination for some of them.

New Hampshire law defines each covered species precisely. “Dog” means any canine animal, male or female, sexed or neutered; “cat” means any domestic feline animal, male or female, sexed or neutered; and “ferret” means any European domestic ferret (Mustela furo), male or female, sexed or neutered.

If you have recently moved to New Hampshire with an unvaccinated pet, the clock starts immediately. Unvaccinated dogs, cats, and ferrets acquired or moved into the state shall be vaccinated within 30 days after purchase or arrival, unless under 3 months of age. You can read more about species-specific rules in our dedicated guides on rabies vaccine requirements for cats in New Hampshire and rabies vaccine requirements for ferrets in New Hampshire.

Rabies Vaccine Schedule and Booster Requirements in New Hampshire

New Hampshire law sets a clear timeline for initial vaccination and follow-up boosters. Getting the schedule right matters — a lapsed vaccine can expose you to the same legal consequences as having no vaccine at all.

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’ (NASPHV) Compendium of Animal Rabies Prevention and Control. That compendium distinguishes between approved 1-year and 3-year vaccines, and your veterinarian will determine which product is appropriate for your pet.

Here is a summary of the core schedule requirements under RSA 436:100:

Milestone	Requirement
Initial vaccination	Within 30 days of reaching 3 months of age
First booster	Between 9 and 12 months after the initial dose
Subsequent boosters	Per the current NASPHV Compendium (1-year or 3-year intervals depending on vaccine used)
Newly acquired or relocated pets	Within 30 days of purchase or arrival in New Hampshire

In rabies-infected areas, dogs, cats, and ferrets recently vaccinated shall be kept under control for at least 30 days before being allowed to run free. Ask your veterinarian whether your area has any active rabies designations that would trigger this additional requirement.

Vaccination requirements vary by state, so if you travel frequently with your pets, it helps to know how New Hampshire compares. You can review requirements in neighboring and other states through our guides on rabies vaccine requirements in New York and rabies vaccine requirements in Maine.

Who Can Legally Administer a Rabies Vaccine in New Hampshire?

Under current New Hampshire law, a licensed veterinarian must administer the rabies vaccine. Rabies vaccination must be administered by a licensed veterinarian at the age of three months, and vaccination against rabies is required under RSA 436:100 for dogs, cats, and ferrets. This means you cannot self-administer a rabies vaccine purchased from a farm supply store and have it satisfy the legal requirement — only a licensed veterinarian’s administration counts.

A 2026 legislative proposal would expand this authority. House Bill 1407 would allow vaccination against rabies to be performed either by a veterinarian licensed to practice in New Hampshire or by a veterinary technician working under the indirect supervision of such a veterinarian. As of January 2026, that bill was introduced and referred to committee; it had not been enacted into law as of the publication of this article.

After vaccination, documentation matters. The veterinarian must complete a certificate of rabies vaccination in triplicate, which includes the owner’s name and address, a description of the animal, the date of vaccination, the rabies vaccination tag number, the type of vaccine used, and the expiration date. The original goes to the owner, one copy is retained by the veterinarian, and one copy goes to the town or city clerk within 40 days. Keep your copy in a safe place — you will need it for dog licensing and may need it in an emergency.

Pro Tip: Ask your veterinarian for a physical copy of the rabies certificate at every vaccination appointment. Town clerks in New Hampshire require it for dog licensing, and animal control officers may request it if your pet is involved in a bite incident.

Medical Exemptions to Rabies Vaccination in New Hampshire

New Hampshire does allow medical exemptions from the rabies vaccine requirement, but the process is deliberate and the bar is high. The exemption process is governed by RSA 436:100, paragraph II, and it is not a simple opt-out.

A rabies immunization exemption may be issued, where illness or a veterinary medical condition warrants, by the local rabies control authority upon the written recommendation of a veterinarian licensed under RSA 332-B. The recommendation must also be signed by an American College of Veterinary Internal Medicine (ACVIM) diplomate and the state veterinarian.

The exemption is valid for one year. After the initial year has expired and if the animal still qualifies, the exemption must be recertified by a licensed veterinarian on an annual basis.

Receiving an exemption does not mean your pet faces no restrictions. The law imposes specific conditions on exempted animals:

• The exempted animal must be maintained in strict rabies isolation, under conditions at the discretion of the local rabies control authority, until the medical condition has been resolved and the animal can be immunized.
• Exempted animals shall not be allowed outdoors without being on a leash and shall be under the direct physical control of an adult owner at all times.
• Exempted animals must also be muzzled when outdoors in a manner approved by the local rabies control authority.

The requirement for an ACVIM diplomate’s signature makes exemptions genuinely difficult to obtain. Some pet owners at a February 2026 public hearing spoke in favor of a proposed bill to loosen exemption rules, saying the current protocol required to attain a medical exemption for their pet was too difficult. State veterinary officials, however, have defended the high standard as a necessary public health safeguard.

What Happens If Your Pet Is Exposed to Rabies in New Hampshire?

How New Hampshire handles a potential rabies exposure depends heavily on whether your pet is currently vaccinated. The outcomes for vaccinated and unvaccinated pets are very different, and the difference underscores why keeping vaccinations current matters beyond just legal compliance.

If your pet is vaccinated and bitten by a known rabid animal: The dog, cat, or ferret shall be immediately revaccinated and confined for a period of 45 days. This is a manageable outcome compared to the alternative.

If your pet is not vaccinated and bitten by a known rabid animal: Dogs, cats, and ferrets that are not vaccinated in accordance with RSA 436:100 and have been bitten by a known rabid animal or have had a nonbite exposure shall be immediately euthanized, unless the owner is unwilling. If the owner refuses euthanasia, strict isolation of the dog, cat, or ferret in a kennel under veterinary supervision and in cooperation with local authorities shall be enforced. A dog or cat held under these circumstances shall be quarantined for a minimum of 4 months.

If your vaccinated pet bites a person: Any healthy dog vaccinated in accordance with RSA 436:100 that has bitten any person and caused a puncture of the skin or caused a nonbite exposure shall be confined by the owner or other responsible person as required by local authorities for a period of 10 days, at which time the dog shall be examined by a licensed veterinarian. The same 10-day observation period applies to cats under RSA 436:105-a.

If your unvaccinated pet bites a person: The owner of a biting animal not vaccinated in accordance with RSA 436:100 shall surrender the animal to Animal Control or a Police Officer for a ten-day observation period. The owner is responsible for any and all costs involved in boarding. A home confinement may be possible, but only if the animal is vaccinated and with approval of the Animal Control Officer or Police Officer.

Important Note: If you believe your pet has been exposed to a potentially rabid animal, contact your veterinarian and local animal control officer immediately. Do not wait for symptoms to appear. The New Hampshire Department of Health and Human Services also advises contacting your healthcare provider if you yourself may have been exposed.

Local and Municipal Rabies Requirements in New Hampshire

RSA 436:100 sets the statewide floor for rabies vaccination, but New Hampshire municipalities have the authority to enforce and administer those requirements through local animal control programs. Individual towns and cities may impose additional rules on top of the state law.

Dog licensing is one of the most direct points of local enforcement. Before a license is issued, the owner or keeper of a dog must furnish to the town clerk verification from a licensed veterinarian that the dog has been vaccinated against rabies in accordance with the provisions of RSA 436. This requirement makes vaccination a prerequisite for something most dog owners need to do annually anyway.

Some municipalities also require vaccination tags to be worn at all times. Tags worn by dogs indicate that the dog is licensed and has been vaccinated, and they also identify the dog’s owner in case the pet becomes lost, injured, impounded, or bites a human or other animal.

Local rabies control authorities also play a direct role in exemption decisions, quarantine conditions, and bite incident protocols. The specific conditions of any exemption or post-exposure confinement are set at the local level, within the parameters established by state law. If you are unsure about your town’s specific rules, contact your local animal control officer or town clerk directly.

Vaccination requirements also apply to animals kept at commercial facilities. Animals shall not be allowed to freely roam a facility unless they are currently immunized against rabies pursuant to RSA 436:100 and are free of visual evidence of communicable disease. This covers kennels, doggy daycares, and similar operations.

Penalties for Non-Compliance in New Hampshire

Failing to vaccinate your pet against rabies in New Hampshire carries real legal and financial consequences. The penalties are outlined in RSA 436, the same chapter that establishes the vaccination mandate.

Any person who violates the rabies control subdivision of RSA 436 shall be guilty of a misdemeanor. In addition, any person or owner who violates any of the provisions of this subdivision or a rule adopted under it may be subject to an administrative fine levied by the commissioner not to exceed $1,000 for each violation.

Beyond the direct legal penalties, non-compliance creates significant financial exposure in other scenarios:

• If your unvaccinated pet bites a person, you bear the full cost of the mandatory observation or impoundment period. The owner is responsible for any and all costs involved in boarding.
• If your unvaccinated pet is exposed to a known rabid animal and you choose the isolation route over euthanasia, the expense of vaccination shall be paid in advance by the owner, and the expense of impoundment shall be paid monthly in advance.
• If your unvaccinated pet is showing symptoms of rabies and has bitten a person, the dog shall be immediately euthanized and the head sent for examination to the public health laboratory, and it shall be the responsibility of the owner for any expense for euthanizing the dog and for preparing the head for shipment.

The financial and emotional cost of a rabies exposure incident for an unvaccinated pet far exceeds the cost of routine vaccination. Staying compliant with RSA 436:100 is the simplest way to protect your pet, your family, and your wallet.

New Hampshire’s rabies vaccination law is clear, consistently enforced, and backed by strong public health reasoning. If your dog, cat, or ferret is not yet vaccinated — or if you are unsure whether their vaccination is current — schedule an appointment with a licensed New Hampshire veterinarian. Compliance is straightforward, and the protection it provides is real.
