Tennessee’s dog bite laws are more layered than most people expect. If you were bitten by a dog in the Volunteer State, the legal path you can take depends heavily on where the attack happened — not just whether the dog had bitten before.
Understanding the one bite rule in Tennessee, how it interacts with the state’s strict liability statute, and what you need to prove can make the difference between recovering full compensation and walking away with nothing. This guide walks you through every key aspect of the law so you know exactly where you stand.
Does Tennessee Follow the One Bite Rule
The short answer is: yes, but only in specific situations. The term “one bite rule” often causes confusion among dog bite victims in Tennessee. Many people mistakenly believe that the law allows dog owners one free bite before they can be held liable for injuries their dog causes. While this concept has historical roots in common law, modern Tennessee law incorporates both statutory and common law principles that go beyond this simplistic notion.
In 2007, Tennessee passed the Dianna Acklen Act of 2007, T.C.A. § 44-8-413, establishing strict liability for canine-inflicted injuries under specific circumstances. The law was passed in response to the 2006 death of 60-year-old Dianna Acklen, who was killed by three dogs in a rural residential neighborhood while taking her regular walk. The Tennessee Legislature passed the Dianna Acklen Act of 2007, which abolished the first-bite rule.
In Tennessee, the state statute for dog bites involves a mix of strict liability and the more forgiving one bite policy. This means that the circumstances of your case play a major role in whether you can pursue a claim against the owner. Specifically, the one bite rule survives in Tennessee as the governing standard when a bite occurs on the dog owner’s own residential or noncommercial property — a carve-out known as the “residential exclusion.”
Key Insight: Tennessee is the only state in the country with a residential exclusion built into its dog liability statute, making it uniquely important to understand exactly where a bite occurred before assessing your legal options.
How the One Bite Rule Works in Tennessee
Under the one bite rule, a dog owner would generally not be held liable the first time their dog bit someone, unless they had prior knowledge that the dog was dangerous. Once a dog had demonstrated aggression, such as through a prior bite or threatening behavior, the owner was deemed to be on notice and could then be held responsible for subsequent injuries. This legal standard placed the burden of proof squarely on the victim, who had to show that the dog had a known history of viciousness and that the owner knew or should have known about it.
In Tennessee, this rule now operates within a dual-track framework. Tennessee’s one bite rule applies in two situations. There are very important differences in how the rule works depending on whether the victim is hurt on the owner’s property or somewhere else.
Outside the owner’s property, if a dog injures someone while off its owner’s property and the owner knew the dog was dangerous, then the owner is automatically liable. There is no requirement to prove that the owner failed to control the dog or acted irresponsibly in some other way. In other words, owners of dangerous dogs are strictly liable for injuries their pets cause in public places or on other people’s private property.
On the owner’s property, the picture changes significantly. Also known as the “residential exclusion,” under the one bite rule, if a bite occurs on property owned by a dog owner, the injured claimant must prove that the owner knew or should have reasonably known that the dog had dangerous propensities. Tennessee is the only USA state that has a “residential exclusion” in its dog liability statute.
Important Note: The residential exclusion covers not just a home the owner owns, but also residential property the owner rents, leases, or occupies with the landowner’s permission. If the bite happens on any of these types of property, the stricter one bite rule standard applies.
The exclusion is a large loophole in the statute because over 50 percent of bites occur on the dog owner’s property. This means that the residential exclusion leaves over 50% of otherwise-qualified victims in Tennessee without compensation.

What Victims Must Prove Under the One Bite Rule in Tennessee
When the residential exclusion applies, the burden of proof shifts meaningfully onto you as the injured party. The basic key to recovery of damages for injuries caused by a dog is the knowledge of the owner or keeper that the animal is vicious or has mischievous propensities. Plaintiffs suing for injuries or death caused by a dog bite must prove three elements: first, they must prove that the defendant owned the dog; second, they must prove that the defendant’s dog caused the injuries; third, they must prove that the defendants knew or should have known about the dog’s dangerous propensities.
The third element — prior knowledge — is typically the hardest to establish. Under the one bite rule, owners can be held liable for injuries caused by their dogs if they knew or should have known that the dog had “dangerous propensities.” This means that the dog has either injured people in the past, or shown that it has a tendency to try to injure people (for example, by attempting to bite or attack).
Critically, proving prior knowledge is only part of what you need in residential exception cases. Under this rule — unlike the rule for attacks in public places — victims cannot sue for negligence. The victim always has to prove that the owner knew or should have known that their dog was dangerous. But even if the victim proves this, the owner will not automatically be held legally responsible. The victim still has to show that the owner is liable under Tennessee’s premises liability rules, or because of another type of negligence. In other words, for injuries that occur on the owner’s property, victims must prove both that the owner knew the dog was dangerous, and that the owner failed to act responsibly under the circumstances.
| Where the Bite Occurred | Legal Standard | Must Prove Prior Knowledge? |
|---|---|---|
| Public place or another person’s private property | Strict liability (Tenn. Code Ann. § 44-8-413) | No |
| Owner’s residential or noncommercial property | One bite rule / residential exclusion | Yes — plus premises liability or other negligence |
| Off-owner’s property, owner knew dog was dangerous | Automatic strict liability | Already established by owner’s knowledge |

What Counts as Prior Knowledge in Tennessee
Prior knowledge — or “scienter” in legal terms — is the cornerstone of any one bite rule claim in Tennessee. The one bite rule stems from the requirement that the injured claimant must show that the dog’s owner “knew or should have known of the dog’s dangerous propensities.” Generally, this means that the dog must have shown aggressive tendencies in the past, so that the owners were already aware that their dog was a risk to others.
A prior bite is the clearest form of evidence, but it is not the only one. Proving that the owner knew or should have known of their dog’s dangerous propensities can only be done by producing evidence that the dog had bitten someone before or that the dog had a history of other vicious or aggressive behavior. To do this, it may be necessary to find witnesses, such as neighbors, who can testify about being chased by the dog or about seeing other aggressive behavior.
Courts would often look to previous bites, reports from neighbors, signs warning of an aggressive dog, or statements made by the owner as indicators of knowledge. Animal control records, prior complaints filed with local authorities, and even the dog’s breed documentation can all factor into this analysis.
Pro Tip: If you were bitten on the owner’s property, start gathering evidence of the dog’s history immediately. Speak with neighbors, check whether animal control has any records on the dog, and document any “Beware of Dog” signs or other indicators the owner was aware of a risk.
Some factors — such as whether a dog had just given birth or had surgery — can make dogs more defensive. While these situational factors may not establish a long-standing dangerous propensity, they can be relevant to whether the owner should have taken additional precautions at the time of the attack.
It is also worth noting that the “should have known” standard means actual knowledge is not required. The owner or keeper of a domestic animal is bound to take notice of the general propensities of the class to which it belongs, and also of any particular propensities peculiar to the animal itself of which he has knowledge or is put on notice; and insofar as such propensities are of a nature likely to cause injury, he must exercise reasonable care to guard against them and to prevent injuries which are reasonably to be anticipated from them. This means an owner who ignored obvious warning signs may still be held liable even without a prior bite on record.

Exceptions and Defenses to the One Bite Rule in Tennessee
Even when the one bite rule applies to your case, a dog owner may raise one or more defenses to avoid or limit liability. These defenses are written directly into Tennessee Code Annotated § 44-8-413 and are available in both strict liability and one bite rule situations.
The statute does not impose liability upon the owner of the dog if: (1) the dog is a police or military dog and the injury occurred during the course of the dog’s official duties; (2) the injured person was trespassing upon the private, nonresidential property of the dog’s owner; (3) the injury occurred while the dog was protecting the dog’s owner or other innocent party from attack by the injured person or a dog owned by the injured person; (4) the injury occurred while the dog was securely confined in a kennel, crate, or other enclosure; or (5) the injury occurred as a result of the injured person enticing, disturbing, alarming, harassing, or otherwise provoking the dog.
- Provocation: If the victim provoked the dog through teasing, tormenting, hitting, or other aggressive behavior, the owner may not be liable. The provocation must be sufficient to cause a normally calm dog to bite.
- Trespassing: Dog owners generally have reduced or no liability when their dog bites a trespasser. However, this defense may not apply to children who may not understand property boundaries.
- Secure confinement: If the dog was properly secured in a crate, kennel, or enclosure at the time of the bite, the owner is shielded from liability under the statute.
- Assumption of risk: If the victim knowingly assumed the risk of being bitten — such as a veterinarian or dog groomer — this may limit or bar recovery.
- Comparative fault: Tennessee follows a modified comparative fault rule. If the victim is found to be 50 percent or more at fault, they cannot recover damages. If the victim is found less than 50 percent responsible, their damages will be reduced proportionally.
In one bite rule cases specifically, an owner can also mount a strong defense by challenging the knowledge element directly. It can be a powerful defense in one bite rule cases for an owner to either argue that the plaintiff has not proven that the owners knew the dog was dangerous, or provide their own evidence that the dog was generally calm and well-behaved.
Common Mistake: Assuming that being an invited guest automatically protects you under the residential exclusion. Because of the residential exclusion, an invited guest who is bitten in the owner’s home cannot automatically get compensation from the owner’s insurance, but a stranger attacked in the street by the same dog is fully covered.
Dog Owner Liability Beyond the One Bite Rule in Tennessee
The one bite rule is not the only route to compensation in Tennessee. A dog bite victim in Tennessee can recover compensation under a special statute and the doctrines of negligence, negligence per se, scienter, and intentional tort. Each theory has different elements and applies in different factual situations.
Under the strict liability pathway, the dog bite statute creates liability if one or both of the following conditions exist: (a) the owner fails to keep the dog under reasonable control, or (b) the dog is running at large. Under the Dog Bite Statute, a dog owner may be held liable regardless of whether the dog has shown any dangerous propensities or whether the dog owner knew or should have known of the dog’s dangerous propensities if (1) the owner is unable to keep the dog under reasonable control at all times; or (2) the dog is running at large.
Under the statute, “running at large” means a dog goes uncontrolled by the dog’s owner upon the premises of another without the consent of the owner of the premises, or goes uncontrolled by the owner upon a highway, public road, street, or any other place open to the public generally. Importantly, Tennessee law does not distinguish between dogs who are allowed to roam free and dogs who escape their enclosures through the owner’s accident or mistake.
Negligence per se is another avenue worth understanding. The violation of a statute or regulation is negligence per se as to members of the class that the statute or regulation is intended to protect. This means that if an owner violated a local leash law or animal control ordinance and you were injured as a result, that violation may itself establish negligence without requiring further proof of careless conduct.
Landlord liability is also possible in limited circumstances. A landlord could be held liable for the acts of a dog only upon proof that he had knowledge of the propensity of the dog to violence, and that he retained sufficient control over the leased premises to afford an opportunity to require the tenant to remove the dog. To see how other states handle landlord and owner liability differently, you can review the dog bite laws in Washington, Oregon, and South Carolina.
Criminal liability is also a possibility in serious cases. In serious cases, Tennessee dog owners may face criminal charges when a dog causes injury due to owner negligence, such as violating leash laws or failing to confine a known dangerous dog. Criminal penalties can include fines, probation, and imprisonment, in addition to civil liability for damages.
What to Do After a Dog Bite in Tennessee
The steps you take immediately after a dog bite in Tennessee can significantly affect the strength of any legal claim you pursue, whether under strict liability or the one bite rule.
- Seek medical attention right away. If the bite breaks the skin, you should always seek help from a medical professional. A professional should always clean out your wound to prevent infection, which can be difficult to do properly yourself. Medical records also serve as critical evidence in your case.
- Report the incident to animal control. Filing a report creates an official record of the attack and may uncover prior complaints or bites involving the same dog — evidence that directly supports a one bite rule claim.
- Document everything. Seek medical attention first, then report the incident to animal control. Document everything with photos and gather witness information. Photograph your injuries, the location of the attack, and any relevant conditions at the scene.
- Record the details promptly. Keep track of all bite-related expenses and write down how and where the bite occurred, so you do not forget key details.
- Identify witnesses. Neighbors, bystanders, or others who have seen the dog act aggressively in the past can be vital to establishing prior knowledge in a residential exclusion case.
- Understand the filing deadline. A dog bite victim has one year from the date of the attack to file a lawsuit in Tennessee. If they file their lawsuit after the deadline, the court will most likely dismiss the case without a hearing, and the victim will lose their opportunity to seek compensation in court.
- Consult a dog bite attorney. Unlike strict liability, negligence requires more evidence. The victim must show that the owner knew or should have known the dog could be dangerous. Because of the higher proof standard, these cases often require help from a Tennessee personal injury lawyer.
Pro Tip: Even if the bite happened on the owner’s property and you are unsure whether you can meet the one bite rule standard, consult an attorney before accepting any insurance settlement. The residential exclusion does not automatically bar your claim — it simply changes what you must prove.
Tennessee’s dog bite laws are among the most nuanced in the country. The interplay between the one bite rule, the residential exclusion, and strict liability means that the outcome of your case can hinge on details as specific as the exact address where the attack occurred. Knowing these distinctions puts you in a far better position to protect your rights and pursue the compensation you deserve.
