As someone who has a conceal carry permit, I find the jokes about using weapons a matter of stupidity. Nothing the poster offered even approached the concept of carrying a firearm to address the situation. Call the cops, gee, what a concept. If you didn't notice you pay for them to respond to this crap. Especially a small town, what the hell else do they do? In a big town, yea, maybe you try on your own to deal with it, but why in a small town? Most people would get the issue. Control your dog, you identified, pretty simple, and yes, I am a dog owner. Then Identitify this neighbor as being an issue. No long discussion needed.
Here is some regional guidance for successfully passing your citizenship interview... If you are in Massachusetts and your interviewer is some guy named Skippy in a polo shirt then avoid talking about firearms. If you are in Georgia and your interviewer is named Billie-Bob then by all means bring up your passion for assault weapons in your interview.

'ya know.. the worst neighbor-enemy I ever had converted to Christianity after I'd prayed for him off and on for a long time.. it was the win-win that nobody saw coming...
Same situation here. I debated whether to tell the story of my reason behind prayer. I don't like to talk about it but the resolution was to my benefit after prayer.
If their cats encroach on your property a trap can be purchased and utilized. I would talk to law enforcement. I would not call 911 but I would call in the noise complaints.
This guy sounds like an animal, so use an electric cattle prod to teach him proper behavior. I'm being serious.
