Sully, President George H.W. Bush’s service dog, is on to his next gig.

This week, Sully was “sworn in” at Walter Reed National Military Center in Maryland. He will now help wounded service members alongside other service dogs.

"We all felt such a tremendous sense of pride," said John Miller, the president and CEO of America's VetDogs, the organization that oversaw Sully’s training as a pup.

Sully, who was named after Captain Chesley “Sully” Sullenberger, was originally raised as a puppy by an incarcerated veteran in a Maryland prison, as the organization does with all of its future service dogs.

The yellow Labrador was given to Bush 41 after the death of his wife, Barbara Bush, to help him cope. A photo of Sully went viral after he lay beside his owner's casket at his funeral last year.

“Sully will go on to spread his love at Walter Reed Hospital. He was a loving companion when my Gampy needed him most,” Jenna Bush Hager, Bush 41’s granddaughter, posted on Twitter on Thursday.
