Shedding is when you and your dog ‘break’ a group of livestock into smaller groups. It is against the instinct of the herd and the dog to do this. Instinct is for the herd to stay together and even if they split, they will rejoin if not stopped. The dog’s instinct, particularly border collies, is to also keep the sheep all together as well. Here is Bill, the human, and Russell, the border collie doing a shed in an AHBA trial at Action K9 Sports. The is the last part of HTD 3 run.
