What's a Dog to Doo??

I am a responsible dog owner;  even been referred to as a "good citizen" by a homeowner describing me to her child when Rudy pooped on her neighbor's lawn strip.  My loaded -down bright blue plastic bag is wagging from my hand to the tune of Rudy's tail on our daily forays.  

 Nevertheless, we find ourselves constantly being assaulted by these tasteless signs of stooping dogs on beautifully landscaped sidewalk strips.    They completely destroy any loveliness there. 

Don't get me wrong, I am the first to step outside and ask someone to pick up after their dog, but..."What's a poor dog to DOO?

I much prefer a hand made sign brought out by our neighbor's child  which sticks into the ground prominently showing off a pile of poo reading
"Bad dog...OWNER!"
