Bests & Worsts Reviews from Amazon

I have a corner lot front yard, facing a cross-street intersection, with occasional foot traffic. The yard has a two foot high retainer wall around the perimeter, of which the local 'Dog Whisperer' likes to let his pooch lift a leg and mark. I can't really blame the dog as this is a natural function; however watching this daily ritual on my security cam got to be annoying, and as it turned out other dogs started sniffing around and doing their thing as well. What could a homeowner do to dissuade such activity? Enter; "Nature's Miracle No More Marking". After giving the retainer wall a good soapy solution cleaning on Saturday, I then sprayed the wall once a day in the early morning and waited to see what would happen when the Dog Whisperer and his pooch came by. Finally - today (Tues.) I watched as the culprits came into view; I saw with my own eyes as the dog sniffed and sniffed, but did not lift a leg. In fact I've never seen dog and master move so quickly past my corner yard. For me this is validation that this stuff really works and that's good enough, that's a win. - I give it 5 stars. Thanks Nature's Miracle.
