I would start in a field with short grass with little distraction, just a short drag around 200 meters around 2-4 hours old, have you got scent shoes ?. Have a piece of skin at the end on a rope with a pole you can flick the skin for him so he can chase and grab put up resistance and let him shake it, he will never get tired of this and you can use this as positive reward and feed when you finish on the skin with a big meal, get the prey drive instilled early, only do a short track with a shallow curve no more than once a week, and never go upping times or making it hard unless he’s succeeded a few times, it’s good to video with a go pro so we can see his reaction to help further regards Wayne.
