Dogs puts excrements everywhere: parks, streets, even restaurants and grocery stores. This society loves poop!

Edit: Many people do not collect their poop. Or leave it behind on fence wrapped in thin bag. And most just pick up like 70% and leave rest. And diarrhoea is just smeared thin all over the floor.

But by "excrements" I also mean urine. And small bits that fall from exposed dirty but-holes, like when dog sits down, and leaves brown marks on white seat.
