I'm glad i'm not the only one who is annoyed by this. I love dogs, but i don't when people don't clear up after them. I'm sure most do, but the few who don't just make everyone else look bad. I too have pushed my pushchair through street ons dark and/or rainy winter afternoons when the poo is disguised. Cleaning poo off a pushchair wheel is very difficult when you live in a flat and do not have an external water source to hose down. The idea of clearing up poo for someone, following them and smearing it over their front door has crossed my mind, but i figured that it might be taking things a bit far!! humph! Fuschia, that is so shocking that someone allows their dog to do that. he chemical stuff sounds like a good idea, but i'd be tempted to catch the crime on camera and have the owner prosecuted. If it's not your doorstep, they will move on to someone else's...unless it is a fox!
