Got to say, I'm totally on board with this project and love the fact it's been done - and how it's been done.
I have a dog. She shits. When she does, I pick it up in a bag and chuck it in a bin. It's not hard and it really annoys me that not all dog owners do it.
Thankfully, I live in London and not Madrid where, apparently, the problem really stinks.
And, just for the hell of it, here's my dog - her name's Peppa and she is, obviously, the greatest dog on the planet.
