Is there a natural and STRONG way to deter dogs from shitting on one's lawn? I would love to know. Dogs are fine, just pick up your shit. I think someone passes by during early or late hours and but doesn't pick up their dog's mess. Owner's like this are pretty pathetic.
I'd set up a cam but don't have the resources right now. A smart sign might be awesome but I think a person like this might be too stupid to read, I dunno.
Suggestions?
