One of my online students asked me for ideas on how to teach the dog to always take the jump back, even if you for example throw the dumbbell badly so that the dog no longer has a straight line to you over the jump. This is one of the basic exercises that we do with our dogs. We let them run between the handler and a helper and we click for jumping. We gradually move to the side so that the dog has to think about what he is doing. If the dog runs past the jump, there is no click and the dog gets to try again.
