I would be surprised if this situation is addressed in your HOA documents.

What about getting one of those no bark thingies? I don't know if they work or not...but it is worth a try.

I am, once again, eternally grateful that I have the most awesome neighbors! While I don't live in a condo/apartment type situation, I might as well. We are on city lots and VERY close to one another. If I had a problem..it would have been addressed long ago. Direct, and polite is where you should begin.
