It’s true: Even in New York City, where foot traffic is intensive, some dog owners habitually neglect to pick up after walkies.

The stretches of sidewalk where you should keep your head down:

The Bronx:
Sedgwick Ave. and Aqueduct Ave.

Brooklyn:
66th St., Brightwater Court, W. 12th St.

Queens:
Arion Road

No especially feculent streets in Manhattan, although anything near a park should be suspect. As for Staten Island — eh, who cares.

I’m surprised wayward canine turds stay on the pavement with any regularity. I thought the cops were pretty diligent about the pooper-scooper laws, given that people rely on clear walkways just to keep the urban crowds moving. It’s the equivalent of leaving debris on a metro-area highway.
