He did not want to miss any opportunity to snack.
A member of the Southland Shafts and Wheels Club, Chittock has shown Buster at A&P shows throughout the region, although she did not do so at the Roxburgh event.
She and Buster will be heading to the Mayfield A&P Show in March.
Three other Clydesdales from the club were at the show, providing rides.
In addition to being shown, Buster also draws a four-wheeled cart, built just for him.
"We drive around Roxburgh and lots of people want to take photos," Chittock said.
He came from a ploughing team in Pukerau and she has had him for three years.
Chittock and Buster completed a Goldfields Cavalcade, with Mr Chittock providing support, two years ago and plan to do more.
