Dice was known for his extraordinary ability to 'track' exactly in his own tracks. This is hard for a horse to do but very important to the film maker who must set his cameras and lights perfectly. When Dice was to work a scene at liberty, the trainer would walk him along the path which he was to follow. Once they were ready to film, Dice was turned loose and cued for the speed they wanted. He never veered from the original walk-through. Black Diamond was the another who could do this (Les Hiton, trainer of Mr. Ed the talking horse, sometimes worked with Dice also), as could our pony, Pixie , although Pixie could not do it as consistently as they could.
