Tennessee Code Title 68. Health, Safety and Environmental Protection § 68-8-107

(a) Any dog found running at large may be seized by any peace officer and placed in an animal shelter in counties or cities where an animal shelter or pound is available.

(b) If the dog or cat is wearing a rabies vaccination tag or other identification, all reasonable effort shall be made to locate and notify the owners who shall be required to appear within five (5) days and redeem the animal by paying a pound fee as set by the city or county legislative body. A failure to pay the pound fee, or have the animal vaccinated if proof of current vaccination is not produced prior to release, shall require the animal to be adopted or destroyed.

(c) If any dog or cat is not wearing a vaccination tag or other identification, the animal may be adopted or destroyed, unless legally claimed by the owner within three (3) days.

(d) No dog or cat three (3) months of age or older shall be released from a shelter without having proof of current vaccination or until it has been vaccinated and, where applicable, a tag issued.

(e) A county may allow, by local ordinance, the adoption of a dog or cat three (3) months of age or older without a vaccination as long as procedures are established to ensure that the animal is vaccinated for rabies within seventy-two (72) hours of release from the shelter.
