run him at a few rabbits were there is sheep he prob take no notice of them..but if he does then let him know your not having it
tbh mate this is one of the worst bits of advise i have read on here (apart from waiting 2 year to stock break) what will be the the out come if this dog misses the rabbit he will look else where and in this case it will be the sheep i personally could not keep a dog that even showed the slightest interest in sheep nearly all my permission has sheep on so its a must for me as soon as the dogs jabbed its in the field with them ive never had any bother stock breakin
