Dog shit

Yesterday I came a cropper trying to navigate a pram and a toddler past a pile of dog shit in the passage right outside the entry to SHJS. What can we do??? I'm so fed up with lazy dog owners who just can't see why they should clean up after their pets.

I know that the Council have put up lots of bins and strongly worded signs, but I can't really see how they can enforce the law (and I'm sure that is what the dog owners think too). I've heard people mention CCTV, but how would that work if all you have is a blurry picture of a dog/owner and a pile of poop?

Is there any way of persuading people that cleaning up after their dog is the best thing to do? Frankly, it they can't be bothered to clean up outside a busy school gate that to me suggests someone who really does not give a **** about where they live - and is there any realistic way of getting through to someone like that?

Sorry, rant over. Does anyone have any ideas? And can anyone solve the mystery of the person who paints round the poo in yellow?!!! I completely applaud their desire to highlight this, but am intrigued about their method.
