Dog training question.

Yes but you need to shock ‘correctly’ and not rely on the collar to do the training.

Yes, exactly. I'll have to look up that Wolter dude.

That's why I suggested Larry Krohn, his YT videos are free and very informative on the use of a collar. He trains two ways one involves treats and then he does the same thing without treats and uses the collar as a reminder of sorts. If the dog does what he wants immediately...no shock, if the dog pauses he bumps the collar only until the dog gets back on track and he stops. He rarely uses a long shock bump.
