Tell your bro to get the dog a no-bark collar and use it before dog goes outside. I train my dogs early on this because a lot of people especially next door neighbors can get easily annoyed.
Your bro needs to have a talk with the neighbor and tell him that he is working on the barking and talk to each other if it is still a problem. He also needs to tell the neighbor that his aggressive actions will never be tolerated again. Don't engage in an argument leave it as a no misunderstanding with the neighbor.
I have seen these things escalate and it can get ugly. Dogs poisoned etc. All bad.
