Hi Josephine71,
Welcome! One of TV's attributes is that it's a dog-friendly community. Dogs are allowed on the squares. Those are the rules. Much as I enjoy seeing dogs on the squares, I do not take my own because he is small and could be stepped on or trip someone.
It is true that some dog owners don't always use good judgement. It is equally true that some non-pet owners don't use good judgement. Some drive too fast, don't enter and exit the roundabouts properly, deprive attending patrons by saving rows of prime seats at popular events for people who aren't there, are rude to others or don't play ready golf.
None of this is the fault of the rules. Likewise, your friend stepped in dog poop not because there's anything wrong with the rules but because some selfish, entitled person failed to follow them.
Pun intended, that's usually why sh** happen.
