I’ve found a good link about barking dog. Hope it helps…

good question I have the same problem I have tried the anti
bark collar the one that gives a loud ring when he barkes
it did not work. we try to keep him in the back room farthest
from the front dor and street but he still barkes if some one
comes I think we need the dog Whisperer

de-bark him. I do recommend getting another dog, he is probably trying to attract attention, because he is not getting enough. Getting this poor dog would surely do the trick.

My friend has a Schnauzer and the collar it’s the only thing that work for her.

have your husband replace the dog with another one.
