Whoa, Nellie! Don’t forget the fine points of “stopping” which have been clarified in the regulations too. Stopping your dog can keep them out of harm’s way, help adjust to a potentially tight spot, and is a critical skill to draft work. In a cart, a reliable stop or "Whoa" is extra important for the safety of the dog. No different than stopping when heeling, or stopping on a rally course, or stopping on a walk when you get to the street corner - it’s a skill you have built already a number of ways. For draft test purposes, please note this applies in all cases where a dog is directed to stop by either the handler or the judge, Per the regulations: A stop is defined as the dog and handler will cease forward motion with the dog taking no more than three steps after the first command is given without a tight leash (if applicable) and without impeding the dog.
