A rabies vaccination violation in Connecticut carries penalties that start at a $136 infraction fine but can escalate quickly: if an unvaccinated dog or cat bites someone or is exposed to a rabid animal, the owner pays for mandatory quarantine, faces strict civil liability for any injuries, and in exposure cases may see the animal ordered euthanized. The vaccination requirement itself covers every dog and cat, indoor or outdoor, with the first shot due between twelve and fourteen weeks of age and boosters on the vaccine label schedule.1Justia.

The $136 Infraction Fine
Failing to vaccinate a dog or cat under Section 22-339b is an infraction.1Justia. Connecticut Code 22-339b – Rabies Vaccination Required for Dogs and Cats Connecticut’s Superior Court infraction schedule sets the total amount due at $136, made up of a $90 base fine plus mandatory surcharges.2Connecticut Judicial Branch. Infractions Fine Schedule Under general infraction law, the fine portion falls between $35 and $90.3Justia. Connecticut Code 51-164n – Procedure Upon Infractions
Owners are required to keep the rabies certificate and produce it on demand to any animal control officer. Failure to show a valid certificate results in a citation.4Justia. Connecticut Code 22-339c – Certificate of Rabies Vaccination
Licensing Penalties Stack On Top
Vaccination problems rarely surface alone. Connecticut requires every dog six months or older to be licensed through the town clerk by June 30 each year, and the clerk cannot issue a license without a valid rabies certificate.5Justia. Connecticut Code 22-338 – Licensing of Dogs, Fees, Rabies Certificate, Exemptions An owner who misses the deadline owes the license fee, the clerk’s fee, and a one-dollar penalty for every month or partial month the dog stays unlicensed. Those charges accumulate on top of the $136 vaccination infraction, so a single encounter with animal control can produce several separate penalties.
Quarantine Costs After a Bite
When a dog, cat, or ferret bites or attacks a person or another animal, an animal control officer must quarantine the biting animal for ten days. On the tenth day, the State Veterinarian or a designee examines the animal to decide whether to lift or continue the quarantine.6Justia. Connecticut Code 22-359 – Control of Rabies
Vaccination status decides where quarantine happens, and the difference is expensive. A vaccinated animal may be quarantined at home if the premises are adequate and the municipality approves. An unvaccinated biting animal must be quarantined in a public pound, veterinary hospital, or approved commercial kennel. Home quarantine is allowed only if a veterinarian certifies medical necessity, and the animal must be vaccinated on the tenth day of quarantine.6Justia. Connecticut Code 22-359 – Control of Rabies
All costs of quarantine, veterinary examinations, vaccination, and any rabies testing fall on the owner. Ten or more days of boarding at a veterinary hospital or approved kennel is not cheap, and owners of unvaccinated pets have no way to avoid those facility charges.
Extended Quarantine or Euthanasia After Rabies Exposure
The ten-day rule applies when your pet bites someone. A separate and much longer quarantine applies when your pet is the one attacked by or exposed to a potentially rabid animal. The commissioner or State Veterinarian sets the length based on the animal’s age, health, vaccination history, and accepted veterinary practices.6Justia. Connecticut Code 22-359 – Control of Rabies
For an unvaccinated dog or cat exposed to a confirmed or suspected rabid animal, the national standard from the National Association of State Public Health Veterinarians recommends euthanasia. If the owner is unwilling, the alternative is strict quarantine for a minimum of four months with no direct contact with people or other animals. That minimum rises to six months when vaccination is delayed after exposure.7National Association of State Public Health Veterinarians. Compendium of Animal Rabies Prevention and Control, 2016 Connecticut’s 2025 legislation codified a minimum four-month quarantine for animals attacked and potentially exposed to rabies, with vaccination required as soon as medically appropriate.
If exposure is confirmed or strongly suspected and the animal cannot safely be quarantined, the state may order euthanasia and rabies testing to protect public health. This is where skipping a vaccination that costs roughly $25 turns into a genuinely catastrophic outcome.
Civil Liability If Your Dog Bites Someone
Connecticut imposes strict liability on dog owners for bite injuries. Under Section 22-357, if a dog damages a person’s body or property, the owner or keeper is liable for the full amount of the damage. The only defenses are that the injured person was trespassing, committing another tort, or provoking the dog. Children under seven are presumed not to have provoked the animal, shifting the burden of proof to the owner.8Justia. Connecticut Code 22-357 – Damage by Dogs to Person or Property
The victim does not have to prove negligence or show any history of aggression. An unvaccinated dog that bites someone creates two problems at once: strict civil liability for the injuries and the infraction plus quarantine consequences. If the bite victim needs post-exposure rabies prophylaxis because the dog’s vaccination status is unknown or lapsed, treatment involves four vaccine doses over two weeks plus human rabies immune globulin, and the cost can run into several thousand dollars.9Centers for Disease Control and Prevention. Rabies Post-exposure Prophylaxis Guidance That medical expense becomes part of the owner’s liability.
Misdemeanor Exposure for Ignoring Orders
After a bite, animal control officers or the Commissioner of Agriculture can issue orders about restraining or disposing of the biting animal. Officers have broad discretion, from muzzling and confinement requirements to permanent surrender. An owner who fails to comply with a restraining or disposal order commits a class D misdemeanor, a criminal offense more serious than the underlying vaccination infraction.10Connecticut Department of Agriculture. Connecticut General Statute 22-358 Continued noncompliance allows the officer to seize the animal and charge the owner for all seizure expenses.
The Medical Exemption
Connecticut allows a medical exemption, but a veterinarian cannot simply write a note. The vet must first examine the animal and determine that the vaccine would endanger its life due to disease or other medical considerations. The vet must then consult with the State Veterinarian or the Commissioner of Agriculture (or a designee). Only after that consultation can the vet submit a formal exemption application on a Department of Agriculture form.1Justia. Connecticut Code 22-339b – Rabies Vaccination Required for Dogs and Cats
An exemption lasts one year. After that, the animal must be vaccinated or go through the renewal process.11Connecticut Department of Agriculture. Information on Exemption from Rabies Vaccination Owners with an exemption certificate can use it in place of a rabies certificate when licensing a dog.5Justia. Connecticut Code 22-338 – Licensing of Dogs, Fees, Rabies Certificate, Exemptions
One important limit: an exempt animal that bites someone or is exposed to a rabid animal is treated the same as an unvaccinated animal for quarantine purposes. The exemption excuses the infraction fine. It does not reduce the public health consequences.
Resolving a Citation
The first step is getting the animal vaccinated. A citation will specify a timeframe for corrective action, and submitting the new certificate to the issuing agency, typically the local animal control office or town clerk, is the fastest path to resolution. The $136 fine must also be paid within the deadline on the citation to avoid further legal action.
If a quarantine order is in play, every condition must be satisfied before the matter closes. For bite-related quarantines, that means completing the full ten-day observation and any follow-up the State Veterinarian requires.
Owners who believe a citation was issued in error can contest it in court. Valid defenses include proof that the animal was vaccinated at the time of the alleged violation or documentation of a current medical exemption. Bring the original rabies certificate or exemption paperwork, not a verbal explanation. A lapsed booster rather than a total failure to vaccinate may be relevant context, but it does not guarantee dismissal, because the statute requires current vaccination status.
