Can you talk to the neighbors and offer suggestions on how to stop their dogs from fence fighting? That is a bad habit and can lead to real fights if their dogs can escape into your yard? They need to stop it. Can you report them to AC if they don’t try to stop it? If there is enough room, I would probably consider a second row of fencing along that side made out of solid cement blocks that prevent them from seeing into your yard and tall enough they can’t jump over.
