no door bell here but a cell phone............
I have had no truoble with a door bell but my male dog loves to bark at one of our friends when he comes in. And to make things bad don't let the cell phone ring.......... he howls it sounds pritty but it can get loud, I almost have him broke of it by doing the (shhhhhhhhhhhhhhhhhh) thing and by letting him at ather times when it is not a hello call he seems to get it.
If it rins and we don't say hello he is aloud to sing but if we say hello he some what stops.
maybe this will help lol. :)
