Rabies Vaccine Requirements for Dogs in Tennessee: What Every Owner Must Know

Tennessee takes rabies prevention seriously, and the law places a clear obligation on every dog owner in the state. It is unlawful for any person to own, keep, or harbor any dog six months of age or older that has not been vaccinated against rabies as required by the state’s anti-rabies chapter. That single sentence from Tennessee Code § 68-8-103 sets the tone for everything covered on this page.

Whether you just brought home a puppy, recently moved to Tennessee, or simply want to make sure you are in compliance, understanding the state’s specific rules around age, booster frequency, who can administer the shot, and what happens in a worst-case exposure scenario will help you protect your dog and stay on the right side of the law. You can also review the general rabies vaccine requirements in Tennessee for a broader overview covering multiple species.

Is the Rabies Vaccine Required for Dogs in Tennessee?

Yes — rabies vaccination is a legal requirement for dogs in Tennessee, not a recommendation. Under Tennessee Code § 68-8-103, it is unlawful for any person to own, keep, or harbor any dog six months of age or older that has not been vaccinated against rabies as required by the chapter or the rules and regulations promulgated pursuant to it.

The requirement applies statewide, but local jurisdictions can go further. In addition to the statewide vaccination requirements, counties and municipalities are authorized to adopt local laws or ordinances requiring the registration of dogs, and any such ordinances must include methods for collecting registration fees and directing those funds toward maintaining a rabies control program. In practice, this means your county or city may layer additional rules on top of the state baseline.

Rabies remains a genuine public health concern in the state. According to the Tennessee Department of Health’s 2024 Rabies Manual, from 2019 to 2023, rabies was identified in eight domestic animals in Tennessee, including seven dogs and one cat. Keeping your dog vaccinated is the most effective way to prevent that number from growing.

Pro Tip: Even if your county does not require a separate dog license, the statewide vaccination law still applies. Check with your local animal control office to find out whether additional registration is required where you live.

At What Age Must Dogs Be Vaccinated in Tennessee?

Tennessee law makes it unlawful to own, keep, or harbor any dog six months of age or older that has not been vaccinated. Dogs may be vaccinated as early as three months of age or at an age specified by the vaccine’s USDA license, but they will be considered noncompliant if they are over six months of age and have not received the vaccine.

The practical window is therefore between three and six months. It is the duty of every owner to have their dog vaccinated against rabies after the dog reaches three months of age. Most veterinarians schedule the first rabies shot as part of a puppy vaccine series, typically at the 12- to 16-week visit, which fits comfortably within the three-to-six-month window the law requires.

One important detail: after the initial dose, your dog is not immediately considered “currently vaccinated.” The Tennessee Rabies Control Manual emphasizes that, following the initial rabies dose, a dog is not considered “currently vaccinated” unless the vaccine was administered at least 28 days previously. Plan your puppy’s first vaccination accordingly so there is no gap in legal coverage.

Age does not grant any exemption from the ongoing obligation. Within states that require rabies vaccination, re-vaccination is required throughout the animal’s life at the appropriate interval for the species as required by state or local laws and regulations. Exemption is not authorized on the basis of age. Senior dogs must remain current just like younger ones.

How Often Does Your Dog Need a Rabies Booster in Tennessee?

The booster schedule in Tennessee follows a two-step pattern. Regardless of the type of licensed vaccine used or the age of the animal at the time of the first vaccination, the animal must be revaccinated one year later. Following the first two vaccinations, booster vaccinations are due at either one- or three-year intervals in accordance with the approved duration of immunity of the specific vaccine used.

Tennessee law does not specify whether 1-year or 3-year rabies vaccines must be used, although local jurisdictions may have stricter laws. That means your veterinarian has discretion in choosing the product, but the booster schedule must match the label of whatever vaccine was administered.

Being “currently vaccinated” means the animal’s first vaccine was given at least 28 days previously and booster doses have been given according to the vaccine label. The revaccination date on the certificate should match the labeled duration of the vaccine used — if a 3-year vaccine is given, the revaccination date should not be recorded as one year later unless it was the animal’s first vaccination.

Being even one day past the labeled expiration date matters. An animal is considered “overdue,” and not currently vaccinated, if just one day beyond the labeled duration of the last rabies vaccine administered — whether that is one year or three years. If your dog falls overdue, contact your veterinarian promptly. A dog that is overdue for a rabies vaccine is considered immediately currently vaccinated at the time the animal is re-vaccinated, and this rule applies regardless of how much time has lapsed since the previous dose.

Pro Tip: Set a calendar reminder a few weeks before your dog’s vaccination expiration date. A single missed booster can shift your dog’s legal status from “currently vaccinated” to “unvaccinated” overnight.

One thing that will not satisfy the booster requirement is a blood titer test. Antibody titers are not accepted in lieu of rabies vaccination in Tennessee. Titers are only one marker of immunity and may not indicate complete protection, and other immunologic factors also play a role in preventing rabies.

Who Can Administer a Rabies Vaccine in Tennessee?

Tennessee law is specific about who is authorized to give a rabies vaccine. Tennessee Code § 68-8 requires that all rabies vaccinations be given by or under the direct supervision of a veterinarian licensed in the state. You cannot legally administer the vaccine yourself, and purchasing it over the counter for self-administration is also restricted.

It is prohibited to sell rabies vaccine for use in dogs and cats to persons other than licensed veterinarians unless the purchaser possesses a prescription for the vaccine from a veterinarian duly licensed in Tennessee. This rule exists to ensure that every vaccination is properly documented and that the certificate issued is legally valid.

Vaccinations given at animal shelters or control facilities follow the same chain of accountability. If the vaccination is given at an animal control facility or shelter, then the certificate must contain the name and signature of the person administering the vaccine as well as that of the supervising veterinarian. The supervising veterinarian’s involvement is always required, regardless of the setting.

Medical Exemptions From the Rabies Vaccine in Tennessee

This is one of the areas where Tennessee’s law stands out compared to many other states. Tennessee has no legal provision that allows veterinarians to exempt, or waive, the rabies vaccination requirement for a domestic dog or cat. There is no formal exemption certificate process at the state level.

That does not mean a veterinarian is forced to inject every animal regardless of health status. A veterinarian must use professional judgment in deciding whether to vaccinate an animal and is not obligated to administer a dose of rabies vaccine. The state advises veterinarians to try all available methods to safely vaccinate the animal, such as different vaccine brands or premedication.

If a pet owner and their veterinarian feel that vaccination is too risky for an animal due to a history of severe vaccine reactions or underlying illness, they may choose not to vaccinate the animal. However, if the pet is then exposed to a rabid animal, it must either be euthanized or strictly isolated for six months. The decision not to vaccinate does not provide legal protection — it simply shifts the risk to the owner.

For clients who refuse to have a pet vaccinated against rabies, the state recommends that the examining veterinarian inform and document the fact that the client understands the potential consequences of not vaccinating, including that if the pet is exposed to rabies or a rabies reservoir species it must be either euthanized or strictly isolated for four to six months at the owner’s expense.

Important Note: Because Tennessee does not recognize a formal medical exemption, an unvaccinated dog is treated as legally unvaccinated in all exposure and bite scenarios, regardless of the reason vaccination was skipped. Discuss your dog’s specific health situation thoroughly with your veterinarian before making this decision.

Proof of Vaccination and Licensing Requirements in Tennessee

After your dog is vaccinated, you will receive a certificate and a rabies tag. Both serve as official proof of compliance. Evidence of vaccination must consist of a certificate containing the owner’s name and address, date of vaccination, date the dog should be revaccinated, description and sex of the dog, the vaccination tag number when applicable, the manufacturer and lot number of the vaccine administered, and the name and signature of the supervising veterinarian.

The tag must go on your dog’s collar and stay there. The person or facility administering the vaccine must issue a rabies tag for every dog vaccinated, and every dog owner must attach a metal tag or other evidence of rabies vaccination to a collar, which must be worn at all times by the vaccinated dog — with the exception that the collar may be removed for hunting dogs while in chase or returning from the chase.

On the certificate itself, Tennessee does require veterinarians to maintain a copy of each certificate issued by the practice, though the duration of time to keep the copy is not specified. It is recommended that a written or electronic copy of all rabies certificates issued be kept for at least three years, or at least as long as the certificate expiration date. Keep your own copy as well — you may need it for boarding, grooming, or travel.

Dog licensing is handled at the local level rather than the state level. Tennessee does not require dog licensing at the state level. State law authorizes counties to license and regulate dogs through their local legislative bodies, but leaves it up to each county to decide whether and how to do so, resulting in a patchwork where some jurisdictions require annual licensing, others do not, and fees vary widely.

As one example, Nashville/Davidson County requires all dogs and cats six months or older to be vaccinated for rabies and registered with the county. Rabies tags are available in one-year and three-year versions, priced at $8.00 and $24.00 respectively, depending on the vaccination administered. Contact your county’s animal control office to confirm what is required in your specific jurisdiction.

If you also have cats or ferrets, the rules differ somewhat. See the separate guides on rabies vaccine requirements for cats in Tennessee and rabies vaccine requirements for ferrets in Tennessee for details.

What Happens If Your Unvaccinated Dog Is Exposed to Rabies in Tennessee?

The consequences of an exposure event differ sharply depending on whether your dog is currently vaccinated. Understanding both scenarios before an incident occurs is worth your time.

If your dog is currently vaccinated: If a currently vaccinated domestic animal is exposed to a confirmed or suspected rabid animal, it should receive a booster vaccine as soon as possible — generally interpreted to mean within 96 hours of exposure — and be observed by the owner for 45 days. If the animal becomes ill during that period, the owner should have the animal examined by a veterinarian.

If your dog has never been vaccinated: The options are far more limited. If a never-vaccinated dog is exposed and the wild carnivore tests positive for rabies or is unavailable for testing, the pet should be euthanized or strictly isolated for six months. That isolation period is at the owner’s expense and must be strictly enforced.

If your dog’s vaccination is overdue: If your dog has fought with a wild carnivore such as a raccoon, skunk, or fox, or had direct contact with a bat and the dog has been vaccinated at some point (regardless of whether vaccination is current), you should see your veterinarian for a rabies booster as well as treatment of any injuries. The pet should then be observed at home for 45 days and examined by a veterinarian if it shows any signs of illness.

When a dog bites a person, the observation rules apply regardless of vaccination status. If a person is bitten by a dog, the animal should be observed for 10 days from the time of the bite, and it does not matter whether the animal is vaccinated against rabies or not.

Penalties for Not Vaccinating Your Dog in Tennessee

Failing to vaccinate your dog carries legal consequences at both the state and local level. At the state level, owning, keeping, or harboring an unvaccinated dog over six months old is a violation of Tennessee Code § 68-8-103, which is enforceable by peace officers including animal control officers, police, and sheriffs.

An unvaccinated dog found running at large can be seized and impounded. Any dog found running at large may be seized by any peace officer and placed in an animal shelter in counties or cities where one is available. If the dog is wearing a rabies vaccination tag or other identification, all reasonable effort must be made to locate and notify the owner, who has five days to appear and redeem the animal by paying a pound fee set by the city or county legislative body.

Failure to pay the pound fee, or failure to have the animal vaccinated if proof of current vaccination is not produced prior to release, requires further action before the animal can be released. In some jurisdictions, the animal will be vaccinated before release and the owner billed for the cost.

Local ordinances can impose their own fines on top of the state framework. Tennessee regulates dog ownership through a combination of state statutes and local ordinances, and the penalties for letting a dog run loose range from a minor fine to a felony if someone gets seriously hurt. Beyond fines, the most significant financial penalty may come from an exposure event — strict isolation for six months, entirely at the owner’s expense, can cost far more than a routine vaccination ever would.

Staying current on your dog’s rabies vaccine is the simplest way to avoid all of these outcomes. If you are also researching requirements in other states — whether because you travel with your dog or are considering a move — the guides on rabies vaccine requirements in Illinois, rabies vaccine requirements in Michigan, rabies vaccine requirements in Pennsylvania, and rabies vaccine requirements in New York provide state-specific detail in the same format.

Key Takeaway: Tennessee’s rabies vaccination law is straightforward: vaccinate by six months, keep boosters current according to the vaccine label, use a licensed veterinarian, wear the tag, and keep your certificate. The consequences of non-compliance — impoundment, fines, and potentially a six-month isolation order — are far more disruptive than a routine vet visit.
