We really just need to make it illegal to use public sidewalks, other peoples private property and any non-dog park as an open sewer for peoples pets. It's not legal for a human to do so, and it shouldn't be legal for pets to either. There are plenty of places where owning or even just bringing a dog is not appropriate.

We don't need to live with this filth, Nobody needs to have a right to treat public property with such disrespect. All this pollution is easily avoidable and very bad for the sensitive ecosystems around the city when it washes into our waterways.

Naturally true service dogs do need to be able to have access, but their waste can also be managed.
