- Sully was placed with 41st president in late June.
Sully the dog will be travelling with the casket on the flight from Texas to Washington DC on Monday.
It appears that Sully and Bush's connection was near instantaneous, with both the former president and the pup's social media accounts sharing pics of their time together. Bush's son President George W. Bush named Roberts chief justice in 2005. "Thank you for your service, Mr. President".

He will be honored during several private and public events in Houston and Washington before he is buried in Texas next to his wife, Barbara, and their young daughter Robin, who died in 1953.
