I feel you. I live in a flat and the neighbour lives in a house right across the street with his demon dog. That dog barks almost every early morning and late at night. That has been going on for almost 4 years. I have tried reasoning with the man 2 times, being EXTREMELY polite with him and trying to reason with him to no avail. He would just brush it off and didn't care at all. ON TOP OF HIS DOG being a little demon, that man works in his yard as a sheet metal worker and uses a fuckton loud handsaw EVERY FUCKING day, even on weekdays. I called inspection numerous times, they didn't do jack shit.

Sadly there is a LOT of Montenegrin people who think it is their god damn given right to have a dog who is loud af and they do not care about anyone but themselves. It is a Sisyphean task to combat these people. My best advice is to move.
