Vermont takes pet vaccination seriously, and for good reason. Animal rabies cases have been rising in Vermont, with 36 animals testing positive in 2025 alone — mainly raccoons, bats, skunks, and foxes. That public health reality shapes some of the clearest and most enforceable pet vaccination rules in New England.
If you own a dog, cat, ferret, or wolf hybrid in Vermont, state law places specific obligations on you — from the age at which your pet must first be vaccinated to how often boosters are required and what documentation you must keep on hand. Understanding these rules protects your pet, your household, and your community.
This guide walks you through every layer of Vermont’s pet vaccination laws, including which animals are covered, age and booster requirements, medical exemptions, local rules that may apply in your town, and the consequences of non-compliance. If you want to stay on the right side of Vermont law — and keep your animals safe — this is where to start.

Which Vaccines Are Required by Law in Vermont
Vermont’s mandatory vaccination law is focused on a single disease: rabies. In Vermont, owners are required to have their dogs, cats, ferrets, and wolf hybrids vaccinated by their veterinarian against rabies in accordance with the vaccine manufacturer’s recommendations, unless exempted by a veterinarian.
No other vaccine is mandated at the state level. While veterinarians throughout Vermont strongly recommend additional vaccines for dogs and cats — such as DHPP and FVRCP — these are not legal requirements under Vermont statute. The law’s singular focus on rabies reflects the disease’s unique danger to both animals and humans and its established presence in Vermont’s wildlife population.
Key Insight: Vermont’s only legally required pet vaccine is the rabies vaccine. All other vaccines, however strongly recommended by veterinarians, are not mandated by state law.
It is also worth noting that rabies vaccinations must be performed by a licensed veterinarian or under the direct supervision of a licensed veterinarian, meaning the veterinarian has examined the animal, authorized its immediate vaccination, and is on the premises at the time the animal is vaccinated. The person giving the vaccination must be employed or working at the same veterinary practice as the supervising veterinarian. You cannot legally self-administer a rabies vaccine to your pet in Vermont and have it count toward the legal requirement.
Rabies Vaccination Requirements in Vermont
Vermont’s rabies vaccination rules are detailed in Title 20 of the Vermont Statutes Annotated, specifically at 20 V.S.A. § 3581, as well as in the Code of Vermont Rules governing the vaccination of domestic pets and wolf hybrids. Together, these sources spell out exactly what a “currently vaccinated” animal looks like under Vermont law.
All dogs and wolf hybrids over three months of age must be vaccinated against rabies. The initial vaccination is valid for 12 months, and within nine to 12 months of the initial vaccination, the animal must receive a booster vaccination. All subsequent vaccinations following the initial vaccination are valid for 36 months.
All vaccinations, including the initial vaccination, must use a U.S. Department of Agriculture-approved three-year rabies vaccine product, and all vaccinations must be conducted by a licensed veterinarian.
Pro Tip: After your veterinarian administers the rabies vaccine, veterinarians are required to provide the owner of a domestic pet or wolf hybrid with a completed rabies vaccination form and tag for each animal that has been inoculated against rabies. Keep this certificate somewhere accessible — you may need it for licensing or if officials request it.
For dogs and wolf hybrids specifically, the owner must maintain a copy of the rabies vaccination form and provide it to state or municipal officials upon request. Licensing a dog also requires proof of vaccination: before obtaining a license for a dog or wolf hybrid six months of age or older, a person must deliver to the municipal clerk a certificate issued by a duly licensed veterinarian stating that the dog or wolf hybrid has received a current preexposure rabies vaccination.
Annual dog licensing is due by April 1 each year. A person who is the owner of a dog or wolf hybrid more than six months old must annually on or before April 1 cause it to be registered, numbered, described, and licensed in the office of the clerk of the municipality in which the dog or wolf hybrid is kept.
Which Animals Are Covered Under Vermont’s Vaccination Laws
Vermont’s rabies vaccination mandate applies to a defined set of animals. Domestic dogs, cats, ferrets, and wolf hybrids are the animals covered under Vermont’s rabies vaccination requirement. Each of these species is specifically named in the Vermont Statutes and the Code of Vermont Rules.
The legal definition of “ferret” under Vermont rules is precise: the term “ferret” means only the European ferret (Mustela putorius furo). Other ferret species or exotic mustelids would not fall under this definition.
Wolf hybrids receive particular attention in Vermont law. A “wolf hybrid” means an animal that is the progeny or descendant of a domestic dog and a wolf. The term also applies to any animal advertised, registered, licensed, or otherwise described as a wolf hybrid, or any animal that exhibits primary physical and behavioral wolf characteristics as defined by the Commissioner of the Department of Fish and Wildlife.
Because no species-specific rabies vaccine exists for wolf hybrids, until the Secretary approves a rabies vaccine for use on wolf hybrids, these animals must be vaccinated with a vaccine approved for domestic dogs, and a veterinarian inoculating a wolf hybrid is not liable for the failure of the rabies vaccine to protect the animal from rabies or for any adverse reaction attributable to the vaccination.
Livestock animals, including horses, are not required by law to be vaccinated for rabies, although it is strongly recommended due to the high prevalence of rabies in Vermont’s skunk, fox, raccoon, and bat populations and the potential exposure of livestock to these wildlife species. If you keep goats or other livestock, you can read more about Vermont’s regulations in our guide to goat ownership laws in Vermont.
Important Note: Rabbits, guinea pigs, hamsters, and other small domestic animals are not covered by Vermont’s rabies vaccination mandate. Small mammals like squirrels, rats, mice, hamsters, guinea pigs, gerbils, chipmunks, rabbits, and hares are almost never found to be infected with rabies.
Vaccination Age Requirements and Booster Schedules in Vermont
Vermont law sets clear age thresholds for when pets must first receive their rabies vaccine, and these differ slightly between species.
Domestic dogs and wolf hybrids three months of age and older must be vaccinated unless exempted. Cats and ferrets over four months of age must be vaccinated.
The booster schedule follows a specific pattern that all Vermont pet owners should understand:
- Initial dose: In Vermont, a veterinarian has the discretion to administer a one-year or three-year labeled rabies vaccine as the initial dose. However, re-vaccination (booster) is required one year following the initial dose, regardless of the animal’s age and regardless of the vaccine administered as the initial dose.
- Subsequent boosters for dogs and cats: When re-vaccinating against rabies, the duration that a dog or cat is considered “currently vaccinated” is strictly determined by the product label of the last vaccine administered — either one year or three years.
- Subsequent boosters for ferrets: When re-vaccinating a ferret against rabies, the duration that the ferret is considered “currently vaccinated” is only one year. This means ferrets require annual boosters throughout their lives.
One important point about timing: an animal is not considered “currently vaccinated” until 28 days following administration of the initial dose of rabies vaccine. This applies regardless of the animal’s age at the time the initial dose is administered.
Vermont law also specifies that a “positive” rabies antibody titer is not recognized as an index of immunity in lieu of vaccination and therefore does not substitute for a required vaccination under U.S. law. Titer testing cannot replace the booster requirement in Vermont.
Medical Exemptions From Vaccination Requirements in Vermont
Vermont does allow for medical exemptions from the rabies vaccination requirement, but they are granted narrowly and carry ongoing legal implications for the pet owner.
In the context of a valid veterinarian-client-patient relationship, and for legitimate medically appropriate reasons, your veterinarian may exempt your dog or cat from the rabies vaccination requirement. The Vermont Agency of Agriculture, Food and Markets directs any questions about this process to the treating veterinarian.
Note that the exemption language in Vermont’s official guidance specifically names dogs and cats. Ferrets are not explicitly included in the exemption provision as stated by the Agency of Agriculture. If you have a ferret with a health condition that may contraindicate vaccination, consult your veterinarian and contact the Agency directly for current guidance.
Important Note: Dogs with medical waivers are still considered unvaccinated for legal purposes. This matters significantly if your pet is ever involved in a bite incident or exposure to a potentially rabid animal. An exempted pet does not receive the same legal protections as a vaccinated pet in those situations.
The practical consequences of being unvaccinated — even with a medical exemption — are significant. Because rabies is fatal, an unvaccinated dog, cat, or ferret that is exposed to a rabid animal should be euthanized so there is no risk that rabies can spread. If an owner refuses euthanasia, a rabies vaccine must be administered within 96 hours of exposure, followed by strict quarantine — four months for dogs and cats and six months for ferrets — precluding direct contact with people or other animals.
This is a meaningful distinction to understand before pursuing a medical exemption. The exemption relieves the legal obligation to vaccinate, but it does not protect your pet from the consequences of a rabies exposure event.
Local Laws That May Add Requirements in Vermont
Vermont’s rabies vaccination mandate is a statewide baseline, but individual municipalities have the authority to layer additional requirements on top of state law — particularly around licensing fees and animal control programs.
A mandatory license fee surcharge of $4.00 per license is collected by each city, town, or village to fund the dog, cat, and wolf hybrid spaying and neutering program. An optional license fee surcharge of up to $10.00 per license may also be implemented by the legislative body of a city, town, or village that has established an animal and rabies control program, for the sole purpose of funding that program.
This means your total licensing cost can vary depending on where in Vermont you live. The State of Vermont Rabies Control Program fee increased from $1.00 to $3.00 on January 1, 2025. The minimum per-license fee now includes a $3.00 state rabies control fee and a $4.00 spay/neuter program fee, for a combined $7.00 that goes to the state — before any local surcharges are added.
Some towns may also have their own animal control ordinances that affect how vaccination records are handled, how stray animals are managed, or what additional conditions apply to certain breeds or species. If you own a pit bull or a dog subject to breed-specific considerations, Vermont’s approach is worth reviewing — see our article on pit bull laws in Vermont for more context. Similarly, if you keep roosters or other backyard animals, local ordinances may intersect with state animal law in ways that affect your responsibilities — our guides on rooster laws in Vermont and rooster crowing laws in Vermont cover those nuances.
When traveling into Vermont with a pet, note that a person may bring a licensed dog into Vermont for a period not to exceed 90 days, provided the owner has a valid, current certificate of rabies vaccination. Out-of-state owners are not exempt from Vermont’s vaccination documentation expectations during extended visits.
Recommended Vaccines Beyond What the Law Requires in Vermont
Vermont law only mandates rabies vaccination, but veterinarians across the state recommend several additional vaccines based on Vermont’s specific disease landscape and your pet’s lifestyle. These are not legal obligations, but they represent a meaningful layer of protection for your animals.
For dogs, Vermont veterinarians commonly recommend:
- DHPP (distemper, hepatitis, parvovirus, parainfluenza) — highly recommended for all dogs. Distemper, rabies, parvovirus, and others are common in Vermont wildlife and some can live in the environment for prolonged stretches of time.
- Lyme disease — highly recommended for most dogs due to the prevalence of ticks in Vermont.
- Leptospirosis — recommended for dogs who often hike in wilderness areas.
- Bordetella — recommended for dogs frequently in social situations such as boarding, training, or dog parks.
- Canine influenza — recommended for dogs in social situations such as boarding, training, and dog parks.
For cats, veterinarians typically recommend:
- FVRCP (feline viral rhinotracheitis, calicivirus, panleukopenia) — highly recommended for all cats.
- Feline leukemia virus (FeLV) — particularly important for cats with outdoor access or exposure to other cats.
Pro Tip: Even though non-rabies vaccines are not required by law, many boarding facilities, groomers, doggy daycares, and training programs in Vermont require proof of DHPP and Bordetella before they will accept your dog. Keeping these vaccines current opens more options for your pet’s care and socialization.
Vermont’s tick and wildlife exposure risks make Lyme and Leptospirosis vaccines especially relevant for dogs that spend time outdoors. The Vermont Department of Health and the Vermont Agency of Agriculture, Food and Markets both provide updated guidance on zoonotic disease risks that can inform your vaccination decisions beyond the legal minimum.

Penalties for Non-Compliance in Vermont
Vermont enforces its pet vaccination laws with civil penalties, and the consequences for non-compliance extend beyond fines — particularly when an unvaccinated animal is involved in a bite or exposure incident.
A civil penalty of up to $500.00 per violation of Vermont’s rabies vaccination rules may be imposed by an officer designated by the commissioner. This penalty applies to violations of the vaccination rules themselves.
Licensing violations carry the same ceiling: a person who fails to license a dog or wolf hybrid in the required manner may be fined up to $500.00. Since a current rabies vaccination is a prerequisite for licensing, failing to vaccinate effectively triggers both the vaccination penalty and the licensing penalty.
The consequences become significantly more serious when an unvaccinated animal bites a person or is exposed to a potentially rabid animal. Regardless of vaccination status, any apparently healthy dog, cat, or ferret that bites a human must be confined and observed for 10 days from the time of the bite under the supervision of the Town Health Officer. However, the outcomes diverge sharply based on vaccination status:
- Currently vaccinated pets exposed to a potentially rabid animal: Dogs, cats, or ferrets with documentation of current or overdue rabies vaccination that are exposed to a potentially rabid animal must be revaccinated immediately and kept under the owner’s control and observed for 45 days.
- Unvaccinated pets exposed to a potentially rabid animal: Because rabies is fatal, an unvaccinated dog, cat, or ferret that is exposed to a rabid animal should be euthanized. If an owner refuses euthanasia, a rabies vaccine must be administered within 96 hours of exposure, followed by strict quarantine — four months for dogs and cats and six months for ferrets — precluding direct contact with people or other animals.
Common Mistake: Some pet owners assume that because their dog or cat has never been outdoors or near wildlife, the rabies vaccination requirement does not apply to them. Vermont law does not provide an exemption based on lifestyle or indoor-only status. The only recognized exception is a veterinarian-granted medical exemption based on documented health reasons.
Wolf hybrids face the harshest consequences under Vermont law in bite situations. Vermont statutes state that since there is not currently a species-specific rabies vaccine for wolf hybrids, any wolf hybrid that bites or otherwise exposes a human, pet, or domestic animal to rabies must immediately be destroyed and its head tested for rabies.
Staying current on your pet’s rabies vaccination is the most straightforward way to avoid all of these outcomes. Vermont’s rules are clear, the penalties are real, and the risks from Vermont’s active wildlife rabies population make compliance genuinely protective — not just a legal formality.
