Why people end up using punishment
Stopping the behavior does not mean understanding it
If they were pulling on the leash from overload, the overload may remain.
If they were growling from discomfort, the discomfort may remain.
If they were chaotic because they could not regulate, the inability to regulate may remain. In other words, punishment can shut down the external expression without solving the internal mechanism. And when the cause remains, the behavior often returns in another form, in another context, or at a higher intensity.
