When marking instead of just eliminating for need, dogs always seem to have just a bit left. That's the problem with dogs who 'over' mark another dogs spot. I have yet to see a dog on empty. I prefer to walk my dogs down the center of the street in my neighborhood because I don't LIKE the distraction of the scents, but that's another story and you can take your life in your hands that way too (I am not a TV resident yet).
There are products you can spray on your lawn to counteract the harmful effects of dog urine, but it is unfair to make the homeowner who doesn't have a dog, or the one whose own dog doesn't use the front yard pay for it. Even if you can speak to the person you see doing it I am sure you can't 'catch' everyone who walks by. At least I know that's how it is here. And everyone denies, denies, denies anyway. Maybe this will raise awareness. Having a friendly and polite discussion never hurts and I liked the suggestion of talking about the dog first then bringing it up. Great idea.
