President George H.W. Bush's spokesman has posted a photo of the late president's service dog lying in front of a flag-draped casket.

Jim McGrath posted a picture Sunday of the yellow Labrador retriever named Sully with the caption, "Mission complete. #Remembering41."

The nation's 41st president died Friday at his home in Houston at 94. He will be honored during several public and private events in Houston and Washington before his burial Thursday in Texas.

Sully will travel with Bush's casket on his flight to Washington, D.C., a source familiar with the plans told CNN.

Sully H.W. Bush, a yellow Labrador retriever, joined the family in June.

The lab assisted the former President in his day-to-day life.

The president had a form of Parkinson's disease, and Sully could open doors, pick up items and summon help.

KTRK-TV in Houston reports that Sully will return to America's VetDogs in New York through the holiday season before joining the Water Reed National Military Medical Center's Facility Dog Program.

Sully is named after Chesley "Sully" Sullenberger III, the airline pilot who was heralded as a hero after he landed a plane on the Hudson River in 2009, saving everyone on board. The incident came to be dubbed "The Miracle on the Hudson."
