update:
I don't want to jinx things (lol) but things *are* getting better. amazing.
I got a call from building mgmt just now asking how the noise level was. other than a short burst of noise today at 8am or so, its been very quiet indeed! the mgr told me that the owner finally did get some kind of shock collar that gives the dog a hint that its behavior is not acceptable

I guess they work! at least so far. I was amazed I got a call from the manager and that there was actual progress toward this resolution.
crossing my fingers now that it stays good
