Bush's Loyal Service Dog Has Last Duty

George HW Bush's spokesman tweeted a poignant image Sunday evening of the former president's service dog, Sully, lying before the former president's casket. "Mission complete," wrote Jim McGrath. Sully, who joined Bush earlier this year and spent the last few months at Bush's side, will accompany the former president's casket from Houston to Washington, DC, reports CNN. Bush will lie in state in the Capitol rotunda from Monday until Wednesday. After a service in DC's National Cathedral, Bush will be taken back to Texas for burial, reports NPR. As for Sully, he will go back to Walter Reed National Military Medical Center, where he'll be reassigned to help a vet. (Bush's last words were to son George.)
