The late President George H.W. Bush's beloved service dog, Sully, has been put back into the workforce—this time, with the United States Navy.

Sully, a yellow lab, will be working at Walter Reed National Military Medical Center outside Washington, where he will be part of the medical center's facility dog program. He'll be striving to reduce stress and increase well-being among patients and staff, including wounded veterans.

The dog, who won viral attention for a touching photo showing him resting near President Bush's casket, was appointed to the rank of hospital corpsman second class during a ceremony streamed live on Facebook Wednesday (Feb. 17), which can be watched above.

The dog, charmingly, was put under oath: "Sully H.W. Bush, do you affirm—or pant—as a hospital corpsman in the United States Navy that you will support, comfort and cheer our warriors and their families, active duty and retired?"

The pup was also urged to give "unconditional love and solace, especially on busy days," and do it all "without any promise of treats or tummy rubs."

He clearly took the responsibility seriously, posting on his official Instagram an acknowledgement of his important duties, adding that his "best friend" would want him to continue his mission of serving veterans.

Sully was assigned to President Bush (a World War II Navy veteran) after the passing of former first lady Barbara Bush in 2018. He was chosen for his adaptability, given Bush's busy schedule. He was trained by America's VetDogs, a nonprofit organization that prepares service dogs for disabled military veterans and first responders.

President George H.W. Bush died on Nov. 30 at the age of 94.
