I found this short video which shows a training session with Bailey, Jason and myself teaching him that Jason can go low in any body position. It was taken when Bailey was four months old, and seven weeks into the training. Bailey is being asked to "shake" Jason's hand (which is part of the low signal chain) whilst Jason goes into various body positions. I then use the 'clicker' to signal what he did right and when. Then he is rewarded and asked to repeat the process.
