On Sunday night, Jim McGrath, the spokesman for the Bush family, shared a photo that shows that people aren’t the only ones mourning the passing of former president George H.W. Bush. The image features Sully, Bush’s service dog, and shows him lying in front of Bush’s flag-draped casket. While the caption says, “Mission complete,” Sully’s work will continue on.

Sully was initially assigned to Bush in June, according to a report by NBC DFW. He was selected specifically for the role by America’s VetDogs, an organization that matches service dogs to active-duty service members, veterans, and first responders with various disabilities.

The two-year-old Labrador retriever assisted Bush with a range of daily activities and even accompanied Bush when he voted in November’s midterms.

Now that Bush is no longer with us, Sully will head back to America’s VetDogs on Long Island. He will remain there through the winter holidays. After that, he is starting his new assignment at Walter Reed Military Medical Center and joins the facility’s Dog Program.

In his new role, Sully will be part of a team of dogs who assist wounded warriors facing the challenges of physical and occupational therapy.

John Miller, the president and CEO of America’s VetDogs, issued a statement after Bush’s death.

“Our thoughts and prayers are with the entire Bush family during this difficult time. It was truly an honor to have provided service dog Sully to be by the president’s side for the past several months,” said Miller.

“As a true patriot and a visionary, President Bush will forever be viewed by people with disabilities and their families as a hero through his efforts to enact the Americans with Disabilities Act,” Miller continued. “We are forever grateful to his service to the American people.”
