One of our neighbours used to let her GSD bark non-stop day and night

he lived out and would bark till 4 in the morning then stop for an hour and start up again at 6. I timed him one day and it was over 12 hours of solid barking ! So we complained. She got very aggressive and ended up screaming at me and OH
in our house one night. Her final piece was that she wouldn't mind so much, but the Dobermann up the street kept her awake and stopped her getting to sleep!

My answer was that if her own dog was quiet she'd be able to ask the Dobe's owners to stop him barking :-D (the Dobe didn't actually bark very often or more than a couple of woofs, just when someone was lurking in the lane) I also offered to get a large parrot and keep that outside so all the neighbours could enjoy the noise it made - I can be really sarky when pushed.
Strangely enough she managed to stop the dog barking for hours on end after that. I find a threat of 'Right back at yer' often works better than reason with some people ;)
