barking dog kept on balkony day and night

Hello! One of our neighbours decided to get a young dog. They are living in an apartment building. Probably because of the size of their apartment or whatever, they have decided to keep the dog the whole time outside on their tiny balkony. The first night we could hear the dog whining a lot. This has improved in the meantime, but now I'm woken up almost every morning around 5 because the dog starts barking - not for long, but enough to wake me up. The whole neighbourhood 'benefits' from the dog. I am very angry at the owner, how someone can act so irresponsibly and selfishly. They are surely happy to have a new dog, but never considered neither their dog nor their neighbours. Is there really nothing one can do? Any advice would be welcome!
