Former US President George HW Bush’s service dog has been pictured resting beside his coffin, in a moving tribute.
Bush, who served as the 41st US president between 1989 and 1993, died late on Friday at the age of 94.
Sully the dog will be travelling with the casket on the flight from Texas to Washington DC on Monday.
Bush’s body is due to lie in state this week ahead of a day of national mourning.
The coffin will be flown from Texas to DC on board Air Force One – temporarily renamed Special Air Mission 41, in homage to the late president – and then back on Wednesday, with Sully accompanying the body throughout.
The picture was tweeted by Bush’s spokesman, Jim McGrath, showing Sully next to Bush’s casket on Sunday along with the caption: “Mission complete.”
Sully is named after the airline pilot Chesley “Sully” Sullenberger, who landed a passenger jet on the Hudson River in 2009, saving all 155 passengers and crew on board.
The two-year-old labrador was assigned earlier this year as a service dog to Bush who used a wheelchair in the last years of his life.
A highly trained dog, Sully can perform a number of commands, including opening doors and fetching items such as the phone when it rings.
He will now work as a service dog, assisting with therapy for wounded soldiers.
