Tennessee Dog Bite Laws: Liability and Victim Rights

Tennessee holds dog owners strictly liable when their dog injures someone in a public place or on another person's property under Tenn. Code Ann. 44-8-413, the Dianna Acklen Act. When a bite occurs on the owner's own residential property, the victim must prove the owner knew or should have known the dog was dangerous.

Tennessee Dog Bite Liability: How the Law Works

Tennessee does not follow a simple one-bite rule. Instead, the state uses a mixed liability system created by the Dianna Acklen Act of 2007 (Tenn. Code Ann. 44-8-413). The type of liability that applies depends on where the bite occurs.

If a dog injures someone in a public place or on someone else's private property, the owner faces strict liability. The victim does not need to prove the owner knew the dog was dangerous. The victim does not need to prove negligence. The owner is liable simply because the dog caused harm while running at large or not under reasonable control.

If the bite happens on the dog owner's own residential, farm, or noncommercial property, a different standard applies. In that situation, the victim must prove the owner "knew or should have known of the dog's dangerous propensities." This is the traditional one-bite rule, and Tennessee refers to it as the residential exclusion.

This two-track system means the location of the attack is one of the most important facts in any Tennessee dog bite case.

The Dianna Acklen Act: Strict Liability Under TCA 44-8-413

The Dianna Acklen Act places two duties on every dog owner in Tennessee:

1. Keep the dog under reasonable control at all times.
2. Prevent the dog from running at large.

An owner who breaches either duty is strictly liable for injuries the dog causes to any person in a public place or lawfully on someone else's private property.

Key Definitions in the Statute

Owner means a person who regularly harbors, keeps, or exercises control over the dog at the time of the incident. A person who is temporarily harboring or keeping the dog is not considered the owner under this statute.

Running at large means a dog goes uncontrolled by the owner onto another person's property without consent, or onto a highway, public road, street, or any other place open to the public.

Exceptions to Strict Liability

The statute provides several exceptions where strict liability does not apply:

• The dog was performing police or military work in an official capacity at the time of the injury.
• The dog was protecting its owner or another innocent party from an attack by the injured person or by a dog owned by the injured person.
• The dog was securely confined in a kennel, crate, or similar enclosure when the injury occurred.
• The injured person provoked the dog before the bite.
• The injured person was trespassing on the private, nonresidential property of the dog's owner.

The Residential Exclusion: One-Bite Rule on Owner's Property

When a dog bite happens on residential, farm, or other noncommercial property belonging to the dog's owner (or where the owner is present by permission of the property owner, or as a tenant), the victim faces a higher burden of proof.

Under this residential exclusion, the victim must prove that the owner knew or should have known about the dog's dangerous propensities. Evidence that can establish this includes:

• The dog has bitten someone before
• The dog has growled, lunged, or snapped at people in the past
• The owner received warnings from neighbors or animal control about the dog's behavior
• The dog's training history suggests it was conditioned toward aggression
• The owner kept the dog specifically for guarding or protection purposes

This requirement exists in addition to any other elements the claimant must prove under Tennessee premises liability or comparative fault law.

Dog Owner Responsibilities Under Tennessee Law

Tennessee law imposes several responsibilities on dog owners beyond the requirements of TCA 44-8-413.

Leash and Confinement Laws

Under Tenn. Code Ann. 44-8-408, it is an offense for a dog to run at large. Many Tennessee municipalities, including Nashville, Memphis, Knoxville, and Chattanooga, enforce local leash ordinances that require dogs to be on a leash in all public areas.

Rabies Vaccination Requirements

Under Tenn. Code Ann. 68-8-103, it is unlawful for any person to own, keep, or harbor a dog six months of age or older that has not been vaccinated against rabies. Vaccinations must be administered by or under the supervision of a licensed veterinarian. Owners must maintain proof of vaccination.

Licensing and Registration

Most Tennessee counties and municipalities require dogs to be licensed and registered. Registration typically requires proof of current rabies vaccination. Check with your local county clerk or animal control office for specific requirements.

Warning Signs for Dangerous Dogs

Owners of dogs that have been designated as dangerous or vicious may be required by local ordinances to post clearly visible warning signs on their property. Failure to post these signs can be used as evidence of negligence.

Victim Rights and Compensation

Dog bite victims in Tennessee may recover both economic and noneconomic damages, subject to certain caps and limitations.

Economic Damages (No Cap)

There is no cap on economic damages in Tennessee. Recoverable economic damages include:

• Medical expenses for emergency treatment, surgery, hospitalization, and rehabilitation
• Future medical costs for ongoing treatment, reconstructive surgery, or therapy
• Lost wages from missed work during recovery
• Loss of earning capacity if injuries limit future employment
• Property damage such as destroyed clothing or personal items

Noneconomic Damages (Capped)

Under Tenn. Code Ann. 29-39-102, noneconomic damages are capped at $750,000 for most personal injury cases. For catastrophic injuries, the cap increases to $1,000,000. Catastrophic injuries include:

• Spinal cord injuries resulting in paraplegia or quadriplegia
• Amputation of two (2) hands, two (2) feet, or one (1) of each
• Third-degree burns over 40% or more of the body or face
• Wrongful death of a parent leaving a surviving minor child

Noneconomic damages cover pain and suffering, emotional distress, scarring and disfigurement, and loss of enjoyment of life. The jury does not learn about the cap during trial; the court applies it afterward.

Statute of Limitations: One Year to File

Tennessee has one of the shortest statutes of limitations in the country for personal injury claims. Under Tenn. Code Ann. 28-3-104, you have one (1) year from the date of the dog bite to file a lawsuit.

This deadline applies to all personal injury tort actions in Tennessee. Important considerations include:

• The clock starts running on the date of the bite, not the date you discover the full extent of your injuries.
• Minors may have extended deadlines. The statute of limitations may be tolled (paused) until the minor reaches the age of majority (18).
• Claims against Tennessee governmental entities must be commenced within twelve (12) months under the Governmental Tort Liability Act, Tenn. Code Ann. 29-20-305(b). That is the same one-year window, not a shorter deadline.
• If the defendant faces criminal charges related to the bite, the deadline may extend to two years.
• Missing the deadline almost always bars your claim permanently. Courts rarely grant exceptions.

Because of this tight deadline, anyone bitten by a dog in Tennessee should consult an attorney promptly.

Modified Comparative Fault: The 50% Bar Rule

Tennessee follows a modified comparative fault system under Tenn. Code Ann. 29-39-102(b). This rule affects dog bite cases in two ways:

1. If the victim is partially at fault (for example, by provoking the dog or ignoring warning signs), the victim's compensation is reduced by their percentage of fault.
2. If the victim is 50% or more at fault, the victim is completely barred from recovering any damages.

For example, if a jury awards $100,000 in damages but finds the victim was 30% at fault for teasing the dog, the victim would receive $70,000. If the victim was found 50% or more at fault, the victim would receive nothing.

Criminal Penalties for Dog Owners

Tennessee imposes criminal penalties on dog owners whose animals cause harm while running at large. Under Tenn. Code Ann. 44-8-408, the severity of the charge depends on the outcome.

This is the standard tier. TCA 44-8-408(i) sets a separate, more severe tier when the dog was trained to fight, attack, or kill, or the owner knew the dog had previously caused serious bodily injury or death: property damage becomes a Class A misdemeanor (up from Class B), bodily injury becomes a Class E felony (up from a Class A misdemeanor), serious bodily injury becomes a Class D felony (up from a Class E felony), and death becomes a Class C felony (up from a Class D felony).

In addition to these penalties, a court must order full restitution for all damages arising from the offense when a dog running at large causes bodily injury, serious bodily injury, death, or property damage.

Court-Ordered Destruction of Dangerous Dogs

Under Tenn. Code Ann. 44-17-120, any dog that attacks a human and causes death or serious bodily injury may be destroyed by order of a general sessions court judge. The district attorney general files the petition, and the owner has five days after receiving notice to appear and show cause why the dog should not be destroyed.

Dangerous and Vicious Dog Designations

Tennessee does not have a single statewide law that classifies dogs into "potentially vicious" and "vicious" tiers for the general public, or that requires dangerous-dog owners statewide to carry liability insurance. Tenn. Code Ann. § 39-17-1363 uses similar "potentially vicious dog" and "vicious dog" terminology, but only to bar people previously convicted of certain violent felonies from owning such dogs; it imposes no general owner duties.

Instead, many Tennessee counties and cities have their own dangerous or vicious dog ordinances that define these tiers and require owners to meet additional conditions, which commonly include:

• Maintaining liability insurance, often at least $100,000
• Keeping the dog in a secure enclosure at all times
• Using a muzzle and leash whenever the dog is in public
• Posting warning signs on the property
• Having the dog microchipped for identification

Check your county or municipal animal control ordinance for the rules that apply where you live. A 2026 bill, HB 1902/SB 1794, would have created a statewide dangerous-dog registry with a $100,000 insurance requirement, but it stalled in committee and was not enacted.

Proposed Dangerous Dog Registry (SB1794/HB1902)

During the 2026 session, the Tennessee General Assembly considered SB1794, a bill that would have created a statewide public dangerous dog registry. The bill would have required owners of designated dangerous dogs to register the dog with local animal control for three years, keep the dog restrained on a leash or in a secure enclosure at all times, and carry at least $100,000 in liability insurance. The Senate Judiciary Committee recommended it for passage with an amendment on March 17, 2026 (8-1), it was placed on the Senate Regular Calendar on March 24, and it was re-referred to the Senate Calendar Committee on March 26, 2026, where it stalled. The companion bill, HB1902, was deferred to summer study in the House Agriculture and Natural Resources Subcommittee on March 18, 2026, ending its progress for the session. Neither bill was enacted, so Tennessee still has no statewide dangerous-dog registry.

Landlord Liability for Dog Bites in Tennessee

Tennessee landlords can face liability for a tenant's dog bite under certain circumstances. To hold a landlord liable, the victim must generally prove:

• The landlord knew or had reason to know the tenant's dog was dangerous
• The landlord had the ability to remove the dog or require the tenant to remove it (for example, through lease terms)
• The landlord failed to take reasonable action to address the known danger

A landlord who rents to a tenant despite knowing the tenant keeps a dangerous dog, or who ignores complaints about an aggressive dog in a shared area, may face partial liability for injuries. Landlords can reduce their risk by including pet policies in lease agreements, requiring tenants to carry renter's insurance with liability coverage, and acting promptly on reports of aggressive animals.

Breed-Specific Legislation in Tennessee

Some Tennessee municipalities have enacted breed-specific legislation (BSL) that restricts or bans certain breeds. Breeds commonly affected include pit bulls, pit bull mixes, and Rottweilers.

However, many Tennessee communities have moved away from breed-specific bans in favor of behavior-based dangerous dog laws. The state does not have a statewide BSL. Specific restrictions vary by city and county, so check your local ordinances for rules that apply in your area.

How to File a Dog Bite Claim in Tennessee

If you have been bitten by a dog in Tennessee, take these steps to protect your legal rights:

1. Get medical treatment immediately. Keep all records, receipts, and documentation of your injuries and treatment.
2. Report the bite to local animal control and law enforcement. Ask for a copy of the incident report.
3. Document everything. Photograph your injuries, the location of the attack, and the dog if you can do so safely.
4. Collect the owner's information. Get the owner's name, address, phone number, and homeowner's or renter's insurance details.
5. Identify witnesses. Get contact information from anyone who saw the attack.
6. Preserve physical evidence. Keep torn clothing, bloodstained items, and anything else related to the attack.
7. Contact a personal injury attorney promptly. Tennessee's one-year statute of limitations is among the shortest in the country.
