I DO want them to bark when it's justified - I live alone, and I don't mind them sounding off when the doorbell rings or someone walks behind the fence in the back yard. I don't think there is a solution - so I'm just venting a bit.
My neighbor recently fenced in a bit of yard side by side with mine for their boxer, and the commotion that ensues when they are all out there is embarrassing. All they see is a dog on the other side of the fence without a leash on - they don't realize that she is penned. Oy.
I've started keeping the tv on most of the day so it's not so quiet, but I don't see that it really makes a difference.
