Sully was born in 2016; his mother is Roxanne. Upon leaving his brood, he was trained by the charity America's VetDogs to perform a two-page list of commands, which includes fetching items, answering a telephone, and summoning help in an emergency. He was assigned to assist George H. W. Bush in the summer of 2018 through the dog's participation in a veteran service dog program at the
Walter Reed National Military Medical Center. According to America's VetDogs, Sully was named after former
U.S. Air Force officer and
US Airways pilot
Chesley Sullenberger III. Sully received early attention from his own Instagram page covering his life and work with the
