Hey Yadad, there are all different ways to go about it but I will give you my version.
1). Prey drive.
Rags attached to string on the end of a good pole, make them compete and change the rags. Few rabbit skins if you can get them to get them used to fur, but honestly there is no real need to do this. Sometimes an auld teddy bear, an old slipper. This is great if you are working during the week or in winter and keep your sessions down to 5mins of chasing. Pups should be fairly wrecked after this and if doing it on your garden pick a bit of the garden you don't like the look
