TN Code § 44-8-413 (2021)
2021 Tennessee Code|Title 44 - Animals and Animal Husbandry|Chapter 8 - Fences and Confinement|Part 4 - Running at Large|§ 44-8-413. Civil Liability for Injury Caused by Dogs

   The owner of a dog has a duty to keep that dog under reasonable control at all times, and to keep that dog from running at large. A person who breaches that duty is subject to civil liability for any damages suffered by a person who is injured by the dog while in a public place or lawfully in or on the private property of another.   The owner may be held liable regardless of whether the dog has shown any dangerous propensities or whether the dog's owner knew or should have known of the dog's dangerous propensities.     Subsection (a) shall not be construed to impose liability upon the owner of the dog if:  The dog is a police or military dog, the injury occurred during the course of the dog's official duties and the person injured was a party to, a participant in or suspected of being a party to or participant in the act or conduct that prompted the police or military to utilize the services of the dog;   The injured person was trespassing upon the private, nonresidential property of the dog's owner;   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;   The injury occurred while the dog was securely confined in a kennel, crate or other enclosure; or   The injury occurred as a result of the injured person enticing, disturbing, alarming, harassing, or otherwise provoking the dog.      If a dog causes damage to a person while the person is on residential, farm or other noncommercial property, and the dog's owner is the owner of the property, or is on the property by permission of the owner or as a lawful tenant or lessee, in any civil action based upon such damages brought against the owner of the dog, the claimant shall be required to establish that the dog's owner knew or should have known of the dog's dangerous propensities.   The element of proof required by subdivision (c)(1) shall be in addition to any other elements the claimant may be required to prove in order to establish a claim under the prevailing Tennessee law of premises liability or comparative fault.     The statute of limitations for an action brought pursuant to this section shall be the same as provided in § 28-3-104, for personal injury actions.   As used in this section, unless the context otherwise requires:  “Owner” means a person who, at the time of the damage caused to another, regularly harbors, keeps, or exercises control over the dog, but does not include a person who, at the time of the damage, is temporarily harboring, keeping, or exercising control over the dog; provided, however, that land ownership alone is not enough to qualify a landowner as a regular harborer even if the landowner gave permission to a third person to keep the dog on the land; and   “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 other person authorized to give consent, or goes uncontrolled by the owner upon a highway, public road, street or any other place open to the public generally.
