Our Mission

Spreading Smiles, One Therapy Dog at a Time

We are an international registry of certified therapy dog teams. At ATD, we provide testing, certification, registration, support, and insurance for members who volunteer with their dogs in animal-assisted activities. Our objective is to form a network of caring individuals and their special dogs who are willing to share smiles and joy with people, young and old alike.

Our therapy dog teams volunteer in a wide range of settings—from airports and hospitals to schools, nursing homes, and even private homes. ATD places no restrictions on where teams can visit. Members may join local therapy dog groups, participate in national initiatives like those with the Red Cross and R.E.A.D., and may also visit alongside teams registered with other organizations.

The ATD Way

Our Approach to Therapy Dog Certification

v

Our Human Members

ATD is powered by volunteers—our Tester/Observers, Board Members, and teams all donate their time, and only our Office Staff are paid. By keeping membership costs low, we ensure therapy dog visits remain free for the facilities we serve.

v

Our Canine Members

Alliance Therapy Dogs welcomes well-mannered dogs of any breed (except wolf or coyote mixes) who love people—no formal training or certifications required. Dogs must be healthy, up-to-date on vaccines, and pass our test, with no restrictions on diet, supplements, or treats during visits.

v

Our Testing Process

Our hands-on testing process focuses on your bond with your dog and ensures they have the right temperament for therapy work. After the Handling Assessment, a Tester/Observer will do 3-4 supervised Observations—including 2 to medical facilities—offering guidance and support before recommending you for certification.
