Tuttle owned and trained his own horses, partially so that the horses could focus strictly on dressage and not be used for other sports or cavalry exercises; this was unusual for the times. He was set apart from many of the Olympic riders of the time by being older, not a West Point graduate, a quartermaster officer, and riding in dressage when few other officers appreciated the formality and discipline of the sport. He trained many of the military dressage riders who followed in his footsteps, including Major Robert Borg who competed in dressage at the 1948 and 1952 Summer Games. After his retirement, Tuttle continued to ride and train, and never sold his Olympic mounts. He is buried along with three of his horses (Vast, Si Murray and Olympic) at the Fort Riley cemetery.
