Once had a neighbor on the other side who left the dog inside when they left which is normally good. This dog did nothing but bark for 2-3 hours constant so LOUD I could hear it 100 feet away through their windows and my windows up and music on.
2-3 hours of constant SUPER LOUD INSENSED barking everytime they left him alone and only when they left him alone.
I recorded it and went over one day.

LOL We were fairly good friends but I dont think they appreciated that BUT you can only handle so much. I was cool. i just played it for them.
They got rid of the dog and moved a while later. Not cause of me.

I just got lucky that they had to move. They had a new dog in there every few months it seemed. Most were not a prob. Some big dogs are f'n loud tho man.
You could hear this dog barking through closed house walls at least 50 yards radius clearly while inside your home. This affected several other homes. That was also a big husky or golden lab mix. Altho labs are usually the best dogs and seldom bark. Big dog tho.
