Several times a week Buzz, a long-haired double dapple dachshund, fulfills his duties as a therapy dog for the students in the deaf education classes at McNeil High School. Buzz, also deaf, knows and responds to sign language.

Trained by The Dog Alliance, Buzz has earned his certification as an American Disability Act (ADA) therapy dog. Watch how students and Buzz work together in the classroom.
