Behavior problems are rarely disobedience — they're rehearsed habits with a payoff. The dog barks and the mail carrier "leaves." The dog pulls and the walk moves forward. Each guide here starts with why the behavior happens, because a fix that ignores the cause just suppresses the symptom until it resurfaces somewhere worse.
Every protocol follows the same arc: manage the environment so the habit stops being rehearsed, then desensitize the trigger, then teach an incompatible calm behavior to replace the old one. The plans are phased by days so you always know what this week's job is — and each one tells you honestly when a problem needs a certified professional instead of a DIY fix.
