I thoroughly dislike that phrase as it does not make neighbors good, just creates more delineated boundaries that are harder to cross and sometimes communicated past. When growing up we had a much larger expanse of land and dogs were able to free-range it. This new reality is being imposed by smaller parcels of land and more people with dogs, especially dogs without gainful employment.
We already have 3/4 of perimeter fenced in. Balance is going to be the problem as it will be without precedence.
The phrase isn't very nice, but a good neighbor wouldn't create a need for a fence, when people are insensitive or irresponsible then I consider the fence a defensive tool, even if they may consider it an offensive one...
I to grew up in an area where fences weren't needed for anything other than some livestock which liked to roam, but it was also a place and time where folks trained their animals (and kids) to be respectful, and took responsibility when that didn't happen.
