Letting management know about their behavior may help protect you in regards to her barking if they complain since management will now know it's the dude's fault she barks.
What about talking to the other 2 that are security guards. Maybe befriend them and they will turn him around.
I wish you the best.
I own my home but it's directly behind a 'low rent' apt complex and I've had issues with many renters over the years (including a guy last year who told his dog to 'get her' directed at my dog barking at him. Luckily, most move out after their lease is up and right now there are 2 cops so all's well.
