Reducing reactivity to the door buzzer

 Here's a very brief demo of my working with Finn to reduce his reactivity to the door buzzer.  This door buzzer is extremely obnoxious. I can't stand the sound of it either.  But he goes crazy when he hears it so we have worked on it and he has made terrific progress.  These practice sessions have resulted in his giving one small bark now when the buzzer rings unexpectedly, and then we both go to the door to investigate (actually, I press the button that opens the lower building door so the visitor can enter the building and enter the elevator.  Finn knows that someone coming up the elevator is the NEXT thing that happens, so we wait in the doorway politely for the person to arrive.  Training is required for that step, too).
