What a charming and obedient dog, Lindy! If you aollow me, I'd like to critisize one thing. Such a cute little creature should never be taught the quiet, but go on with his melodious bark as often as possible. But don't listen to me. Mark will certainly fully disagree!

That is much quieter then she usually responds at the door. She has an almost frantic bark when someone comes over and rings the doorbell. Her owners would be very happy if this was all she did!

Short and sweet!

A perfect sequence with using the doorbell.  The overall timing of everything was just spot on.  From your helper ringing the bell when you said "okay" to your marks and rewards.  

Great job!
