Tennessee Dog Bite Laws: Liability, Dangerous Dog Rules, and Insurance
What Tennessee law expects from you as a dog owner — who pays after a bite, how a dog gets designated dangerous, and whether the state requires liability insurance. Every citation links to the official statute.
This page is not legal advice. It summarizes Tennessee state law as of 2026-07-13. Laws change and cities add their own rules — personally check the official statutes linked below, and talk to a licensed Tennessee attorney before acting on anything that matters.
| Liability rule | Mixed (statute + common law) |
|---|---|
| Bite statute | Tenn. Code Ann. § 44-8-413 (strict liability in public/lawfully-present cases; knew-or-should-have-known standard on the dog owner's own residential, farm, or noncommercial property) |
| Dangerous-dog statute | none found (Tennessee has no formal "dangerous dog" designation/registration statute; see section 2) |
| Insurance requirement | No statewide requirement found |
Who pays when a dog bites — the Tennessee rule
Tennessee splits liability by location. Tenn. Code Ann. § 44-8-413 sets a strict-liability rule for bites in a public place, or on someone else's property where the injured person had a legal right to be. There, you can be held liable even if your dog never showed aggression before and you had no reason to think it was dangerous.
The rule changes on your own turf. If the bite happens on your residential, farm, or other noncommercial property, the injured person has to prove you knew or should have known your dog had dangerous tendencies. Because the statute runs a true strict-liability standard in one setting and a knew-or-should-have-known standard in another, Tennessee counts as a mixed state rather than a clean strict-liability or one-bite state.
Five situations take strict liability off the table for a public-place or third-party-property bite: your dog was a police or military dog on duty against a suspect, the injured person was trespassing on your nonresidential property, your dog was defending you or another innocent party from an attack, your dog was securely confined in a kennel or crate, or the injured person provoked the dog.
Separately, running a dog uncontrolled in public or on someone else's property without consent is a crime under Tenn. Code Ann. § 44-8-408, not just a civil-liability trigger. Penalties climb from a Class C misdemeanor with no injury up to a Class D felony if the dog causes a death, and up to a Class C felony for a death if you already knew the dog was dangerous from a prior serious bite. A person hurt this way can pursue both criminal restitution and a separate civil claim under § 44-8-413.
How a dog gets designated dangerous
Tennessee has no statute creating a formal dangerous-dog or vicious-dog designation. There is no state classification process and no post-designation confinement, muzzle, signage, or registration requirement.
What exists instead is a case-by-case judicial track. Tenn. Code Ann. § 44-17-120 lets a general sessions court order a dog destroyed after it attacks a human and causes death or serious bodily injury, on a petition from the district attorney general. You get formal notice and five days to appear and show cause before the order takes effect. Counties over 800,000 people, and metro governments over 100,000, may adopt their own local ordinances covering disposition of dangerous dogs, so even this process partly defers to local government in Tennessee's largest jurisdictions.
Because there is no statewide designation statute, there are no statewide owner obligations that kick in after a dog gets labeled dangerous. Any confinement, signage, or registration rules along those lines exist only at the city or county level.
Insurance requirements
Tennessee law does not require dog owners to carry liability insurance, a bond, or any other proof of financial responsibility. This covers the running-at-large and civil-liability statutes (§§ 44-8-408 through 44-8-413) and the destruction statute (§ 44-17-120) in full, and it applies even if a dog has bitten before. There is no dangerous-dog registration fee or bond requirement at the state level, because there is no state designation process for one to attach to.
This page covers state law only. Tennessee cities and counties can layer on their own local licensing, leash, or insurance-type requirements through animal-control ordinances, which are not covered here.
Worth knowing
- Breed rules stay local. Tennessee has no state law blocking cities and counties from passing their own breed-specific ordinances. A 2022 bill to preempt local breed restrictions was defeated, so places like Nashville-Davidson County keep authority to write their own breed-based rules.
- Bite quarantine has no fixed day count in the statute itself. § 68-8-109 requires a dog that has bitten someone to be placed under observation by confinement or quarantine, with the length set by department rules and the national rabies compendium. Public health sources commonly cite 10 days as the practical standard, but that figure is not written into the law, and the observation can sometimes happen at your own home if animal control allows it.
- Livestock damage runs on an older, separate rule. §§ 44-17-201 and 44-17-202 make a dog owner liable for livestock a dog kills or damages, and say not knowing about the dog's vicious habits is no defense. This rule predates the personal-injury statute by more than a century and does not govern bites to people.
Other states
Rules change at the state line — a dog that is fine at home can put you under a different liability standard on vacation. See the full 50-state table.
