Lincoln is a Prix St Georges dressage horse who's lazy to lunge. Behaviourist Richard Maxwell explains it's common for horses to get emotionally switched off and then need constant nagging. Also, over-familiarity with his trainer puts Lincoln in a position of disbelieving what he's being asked, so he does his own thing and slows down. Then when asked to move on, he over-reacts and accidentally learns that his size, speed and strength are a useful advantage. Richard demonstrates how to get Lincoln to take more responsibility. The result is a proper 'teacher-pupil' relationship, an open channel of communication and a clear understanding.
