Please BEWARE! ATTS tests are NEVER offered to individual dogs at the owner’s home. If someone approaches you to test your dog at home, this person is NOT associated with ATTS. ALL official ATTS tests are sponsored by recognized dog clubs and organizations and are listed on the ATTS website. Please contact ATTS for more information if you are unsure if an event or individual is legitimately associated with our organization.

Welcome to the website of the American Temperament Test Society, Inc. (ATTS). We hope that you will be able to find the answers here to many of your questions about our organization and the TT (Temperament Tested) title for dogs.
