Izzy must poop on the sidewalk most of the time. There are few opportunities for her to poop on grass, which had been her preferred poop-target. With a six poung dog, the poop is petite, not some big stinking yucky pile. Of course, any responsible dog owner will up their's dog's poop, right?
In our neighborhood, there are many places to deposit the picked-up poop. A block from our house, there are trash disposal receptacles. All of the trash from our house goes in there. They have plastic, paper, and everything else (restaval). And they are located every couple of blocks. (On Tuesday mornings we can hear the city truck emptying them.) With trash disposal this easy, you would think that everyone would drop their trash here. But the amount amount of trash on the street and sidewalks is quite surprising and our neighborhood regularly has all kinds of stuff on the ground. Number 1: cigarette butts. Then, dog poop, paper, cups, beer cans, bottles, newspaper, boxes, and wrappers. Don't even get Susan started on construction sites, like the many buildings that are being rehabbed in the neighborhood.
When growing up, there were campaigns to discourage littering: Keep America Beautiful, and Litterbug shaming. As a result, I think it became more of a cultural value. Maybe they need one here.
Having whined about that and declared American superiority, I admit that I could be wrong. We live in an urban area here. Maybe a comparable neighborhood in Boston or Cambridge would have similar trash problems. But I call on my fellow Amsterdammers: don't be a litterbug!
