This gives the handler the most control over both the stock and the dog. He can help guide the dog. Except for the cross drive panels, the handler cannot go through the obstacles, however the dog can go through the obstacles as well as the stock. The livestock should flow through the course like water. Moving slowly and smoothly.
Any deviations are deductible points.
At the intermediate level, the handler is confined to a zone. This means that the handler must be further away from the dog. The handler cannot help the dog quite as much. At advanced, the handler is confined to the handler's post through the majority of the run. This requires the dog to push the stock through the course without any physical assistance from the handler.
