The set point exercise is pretty much the only grid that will teach your dog the proper mechanics of getting themselves to lift off of the ground and over a jump. There is no speed, there is no distance, and there is no influence from the handler on this one....it's just the dog jumping one jump. This grid really should be often as a dog is learning how to jump so they get used to how jumping correctly feels.
With the set point exercise there are two jumps, one's called the facilitator jump and the set point jump your dog is be jumping over. The facilitator jump can be a jump bump or a non-winged jump set at the height of about 4 - 6" depending on the height of your dog. This facilitator jump is never set higher than 6" or else the whole purpose of the set point exercise is lost. All the facilitator jump is defines the space that is available to the dog and more of less put them in the right place for take off. That space will cause your dog to step in, rock back on to it's rear, spring into the air and drop it's head while it's over the jump. The distance the facilitator jump is from the set point jump and the distance your dog is from the facilitator jump is dependent on how long your dog's back is.
The set point jump can be any agility jump you choose with the exception the broad jump. The height of the jump can be anywhere from low to your dog's competition height. Salo does recommend that when working with the set point exercise to change the height of the jump often so the dog will pay better attention to what the job at hand is.
On the other side of the set point jump is a target (that is easily seen by the dog) with a reward. It needs to be far enough away from the set point jump that the dog can finish it's stride after it's landed. This can be anywhere from 6 - 10' depending on the size of your dog.
And so what are you doing while your dog is working the grid? Not a whole lot to be honest. Where you stand is one step ahead of where the target is and one step away off to the side. This way your dog can get to the target and not charge ahead of you. (In the videos I'm going to be posting...I am not in the position because I wanted to show you what my dogs were doing from the side.) Make sure you switch sides of the target at your body is facing the same directions as your dog is heading.
