Hopefully, this is actually not happening though, because if it is, and you combine that with the effects of suburban sprawl and rural land development (which will only get worse in coming years), we will find ourselves in a situation where we need super gritty bottomless running catch dogs, but then not be able to run them because every five minutes the race will cross a property line.
You just described south Florida suburbia to a tee... and their grass patch dogs
