Sully, former US President George H.W. Bush's faithful service dog, has made a final journey back to the US capital with the late president.

美国前总统老布什忠实的服务犬萨利陪它已故主人最后一程飞回华盛顿。

Bush family spokesperson Jim McGrath posted a touching photo of the yellow Labrador retriever lying down in front of Bush's casket in Texas.

The two-year-old labrador had been at Bush's side since June, a few weeks after his wife Barbara's passing.
