Flert pole gets um moving a bit as long as you keep it fun for the pup, breaking to sheep as a young pup you should have no probs use a stern voice and keep the pup on the lead... With an older pup or young sapling a washing line tied to its coller and walk to the sheep if the dog runs at them, yank the line it will stop it getting to them pluss giving you full control of the pup ....
