Not so fast.
It would give the dogs being walked by, by their non-respectful owners, something else to urinate on besides my lawn, corner garden, and trees.
I've pretty much won the feces battle, though. A combination of repellent capsaicin spray and diazinon-like pesticide around the lawn periphery and on the planting strip is effective. The occasional plop is dealt with as usual - scooped up and placed in the middle of the sidewalk...does send the desired message.
What a civil society it would be, if 40 years ago, a bunch of Age of Aquarius self-serving nipsh*ts didn't wring their hands and sob over a man's urban fencing.
