WASHINGTON D.C. - Former President George H. W. Bush's service dog, Sully has one final mission before his next assignment.
He's accompanying the casket to Washington D.C.
The former president passed away Friday evening at 94-years-old.
Sully made headlines Sunday when President and Mrs. Bush's post-White House spokesman, Jim McGrath, shared the photo of Sully laying next to his late owner's casket on Twitter.
The 41st president added Sully to his family this past June. Bush received the lab from America's VetDogs, a nonprofit that provides service dogs to veterans, active-duty military members and first responders with disabilities, at no cost to them, according to their website.
According to CNN, the Bush family named Sully after former airline pilot Chelsey "Sully" Sullenberger III who, in 2009, landed a damaged passenger airplane into the Hudson River and saved all passengers and crew members on board.
Later this week Sully will return to America's VetDogs in Smithtown New York for a temporary stay during the holidays, then he will join the Walter Reed National Military Medical Center's Facility Dog Program, according to WPVI.
Sully will reportedly be working with other VetDogs to assist with physical therapy and occupational therapy to wounded soldiers and active duty personnel while they recover.
