When the pup gets back to his owner, the stimulation turns off. Dogs are extremely place-oriented. The dog may associate the spot by his handler's feet with safety and hunting out in front with danger. Here's the right way. This is the first stage of training before administering correction to achieve excellence.
Excellence is achieved when the dog performs the command the first time the command is given.
I simply repeat the command over and over while showing the dog what the command means. Excellence will come later. If punishment training is the sole training program, the dog will only respond when afraid of being punished. Put a few bushes and some distance between you and your dog, and your dog no longer responds. Punishment training without the prior fundamental training will create a dog that performs inconsistently at best.
