Sully, a Labrador service dog who worked with George H.W. Bush, just visited the former president's casket in the US Capitol Rotunda.
Sully traveled to Washington, DC, from Texas with Bush's casket and the Bush family.
The yellow lab went to work with Bush this summer after former first lady Barbara Bush passed away earlier this year. Sully can perform a two-page list of commands, including answering the phone and fetching items.
So what happens to Sully now? A highly trained service dog, Sully will now go back into service to help other veterans and is going to Walter Reed National Military Medical Center, former President George W. Bush wrote in an Instagram post.
"As much as our family is going to miss this dog, we're comforted to know he'll bring the same joy to his new home, Walter Reed, that he brought to 41," Bush wrote.
Watch the moment Sully arrived:
