K, we have tried the collar (have raised and trained Rotties all my life, so very comfortable working with it) Tried the ignoring it she kept barking for 5 hours til her voice gave out. We do not make a fuss over the door, as I own a business people come in and out often and there is no excitement over it. We have tried the sit method so she now sits and barks. We have contacted a behavorist who advised a spray bottle of water, which she LOVED. and yes I have already worked with a can with pennies, and also crating her. Like I said I am way out of ideas or methods. So any other advice will be gladly accepted! (thought about sending her to siberia but her Dad says she will think it is a vacation!)
