No American dog law might be more infamous than the NYC pooper scooper law and for good reason. In the 1980s New York City was a filthy place. NYC be much cleaner now but the pooper scooper lawn remains and here are the keys to know: 1. Any person walking a dog must clean up after it. 2. This law does not apply to any guide dog accompanying a blind person. 3. A New York City agent must witness someone not cleaning up after their dog to issue a ticket. 4. The maximum fine is $250. There are three ways to report dog waste in NYC: 1. Dog waste on the street, sidewalk, or adjoining area. 2. Dog waste on private property. 3. Dog waste in a public park. Regardless of who causes dog waste, property owners are responsible for maintaining their property, adjoining sidewalks, and gutters.
