The labrador who worked as a service dog for President George HW Bush has been pictured resting beside his coffin, in a moving tribute. It will travel with the casket on the flight from Texas to Washington and back this week.
A highly trained dog, Sully can perform a number of commands, including opening doors and fetching items such as the phone when it rings.
He will now work as a service dog, assisting with therapy for wounded soldiers.
This is why "dog is man's best friend".
