One, he bolts from the spot and runs as quickly and as far away as he can. A second response may be to freeze on the spot until the stimulation turns off. In both cases, the dog learns that if he grits his teeth for 10 seconds, the stimulation goes away. Pup comes running back to his owner. When the pup gets back to his owner, the stimulation turns off.
Dogs are extremely place-oriented.

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.
