What's complicated? People used to let the dog run wild and didn't care. Now they rag on the kids, who are maybe 7 or 8, and home alone, to keep the dog restrained.
The don't cause they're kids, but they do run out into the streets to catch the dog.
And the parents are either ignorant or don't care. Till some bubblehead blows by and a kid runs out in front of them, chasing the dog. Then they'll care.
Me,I'd rather take the chance the dog might get hit and oh well.
PS, I'm a dog lover. And this is an upscale neighborhood.
