Tennessee Dog Bite Law: How Dianna's Law Works

Is a Dog Owner Liable for a Bite in Tennessee?

It depends on where the attack happened, and Tennessee is the only state where that is the deciding question.

In a public place, or anywhere you are lawfully present on someone else's property, the owner is strictly liable under T.C.A. § 44-8-413.^[1]

You do not have to prove the dog was known to be dangerous.

On the owner's own residential property, the rule flips, and proving what the owner knew becomes the whole case.

Serious attacks mean reconstructive surgery, scarring, infection risk, and, for children especially, lasting trauma.

Here is how Tennessee's split rule works and what it means for your family's claim.

The Law Named for Dianna Acklen

Tennessee's dog bite statute has a name and a history. In 2006, 60-year-old Dianna Acklen was killed by three dogs while taking her regular walk in a rural neighborhood. Before her death, Tennessee dog owners were largely protected by the common law "one bite" rule: an owner was liable only if the dog had already shown its dangerousness.

The legislature answered in 2007 with the Dianna Acklen Act, T.C.A. § 44-8-413, which imposed a duty on every owner to keep their dog under reasonable control and off other people's spaces, and made owners strictly liable when a dog running loose hurts someone. Strict liability means the victim does not have to prove the owner knew the dog was dangerous. The attack itself, in the wrong place, is enough.

Where the Bite Happened Decides Which Rule Applies

In public, or lawfully on someone else's property: strict liability. A bite on a sidewalk, in a park, on a greenway, at a store, or while you are visiting a property with permission puts the owner on the hook without any proof of the dog's history. Control was the owner's job, and the injury is the owner's responsibility.

On the owner's own residential property: the exclusion. When the attack happens at the owner's home, farm, or other noncommercial property, and you were there lawfully, strict liability disappears. You must prove the owner knew or should have known the dog's dangerous tendencies, the old one-bite rule surviving inside the modern statute.

The same dog, the same bite, the same injuries can be a strong case at the park and a contested one in the owner's backyard. Location is the first question we ask.

Tennessee Is the Only State With a Residential Exclusion

No other state draws this line, and it is not a small one: a large share of serious dog attacks happen on the owner's own property, to guests, to children playing, to relatives, to workers. For all of those victims, the case turns on knowledge:

• Prior bites, snaps, or lunges at people or other animals
• Complaints from neighbors, mail carriers, or delivery drivers, and any animal control reports
• The owner's own precautions: a warning sign, a muzzle, a chain, or "keep back" instructions all show the owner understood the risk
• Veterinary and shelter records noting aggression

Tennessee's rule is breed-neutral. What matters is this dog's history, and the evidence for it usually comes from neighbors and records nobody thinks to preserve until a lawyer asks.

Who Actually Pays a Tennessee Dog Bite Claim?

Almost never the owner personally. Homeowners and renters insurance policies typically cover dog bite liability, which means a claim can be pursued without bankrupting a neighbor or a relative, a genuine concern that keeps many victims, especially family members, from calling anyone.

The insurer behind the policy will handle the claim like any other: contesting what the owner knew, questioning the severity, and offering early and low. Treating a dog attack as a real injury claim, with documented wounds, scarring photographs, and infection follow-up, is what moves the number.

Children Are the Most Common Serious Victims

Children take dog attacks to the face and head at rates adults never see, and the consequences, reconstructive surgery, permanent scarring, and fear that outlasts the wounds, drive the most serious claims. Two Tennessee rules matter for families:

First, scarring and disfigurement are non-economic damages with real value, and a child carries them for decades. Second, an injured minor's own claim is paused until age 18, but waiting years to investigate is how the knowledge evidence disappears. Document now, decide later.

The One-Year Clock Applies Here Too

An adult's dog bite claim in Tennessee runs on the state's one-year filing deadline, the same clock as other injury claims, with the same narrow exceptions, mapped on our page covering the Tennessee statute of limitations. Attacks connected to a property owner's broader negligence, poor fencing at a rental property, a landlord who kept a known dangerous dog on site, can also raise Tennessee premises liability questions worth reviewing early.
