Myself I don't mind barking dogs if its not the kinda bark that makes me wonder "is that dog ok?" We are lucky with Buddy as he is not a barker but last week someone called our house late at night and started yelling about that barking dog outside and hung up b/4 we could get a word in! Buddy was sound to sleep in the bedroom at the time!
But my mother Inlaw can't stand a barking dog and really gets on her nerves. Do you have a doggie door? We leave our dog out when we leave and find much of the time he goes inside after we leave. Sounds like the new citronella collar might work for you. I hope you find something that will work out for you.
