A service dog, who made headlines for refusing to leave the side of former US President George HW Bush, has a new job.
Yellow Labrador retriever Sully will help wounded soldiers at a hospital in Washington, DC.
A photo of the service dog lying in front of Mr Bush's flag-draped casket went viral in December.
Sully also travelled with the former president's casket on his flight from Texas to Washington.
The canine has his own Instagram account under his full name, Sully HW Bush.
Mr Bush received Sully, after his wife Barbara Bush died, from America's VetDogs non-profit organisation.
Sully was specifically matched to provide support and companionship to Mr Bush in his later years.
Sully is named after former airline pilot Chesley 'Sully' Sullenberger III, who became famous for landing a damaged passenger jet on the Hudson River in 2009.
He will now be based at the Walter Reed National Military Medical Centre.
Accepting his new post, he said on Instagram: "Today I became an official Facility Dog - HM2 Petty Officer.
"It's an honor and privilege to join a wonderful group of dogs at @WRNMMC and I look forward to continue my mission to serve veterans as my best friend wanted me to."
