Senate Bill 391 amends Tennessee law to establish guidelines for the use of certified facility dogs in court proceedings. The bill defines key terms, including "assistance dog organization," "certified facility dog," and "certified handler," and outlines the requirements for a dog to be considered certified. These requirements include documentation of training from a recognized organization, a minimum of two years of training, a current health certificate from a licensed veterinarian, and proof of liability insurance. The bill also stipulates that a certified handler must accompany the dog during court proceedings to ensure proper protocol is followed.

The legislation allows courts to permit certified facility dogs to accompany victims or witnesses during testimony to alleviate stress and improve the accuracy of their statements. It mandates that the court inform the jury of the dog's presence while ensuring that it does not prejudice any party involved. Additionally, the bill requires that the certified facility dog wear visible identification while working and that a motion be filed for court approval prior to the dog's use in proceedings. The act will take effect upon becoming law.
