Sully, George H.W. Bush’s service dog, visits his late master’s casket at the US Capitol Rotunda. The labrador went to work with Bush this summer after former first lady Barbara Bush passed away earlier this year. 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. 📸Drew Angerer/Getty Images #Sully #SullyHWBush #georgehwbush #HWBush #Bush41 #USCapitol #capitol #WashingtonDC #Washington #DC #news #cnnpolitics #politics #us
