People that for some reason think that their duty to tidy up after their dog, ends once they have collected the poop in a bag. Said bag is then left in a bush or beside something. I would actually rather it be left outside the bag so that it could bio-degrade into the ground than be sat in a bag? Obviously I would rather bag was placed in an appropriate bin to be honest and there are enough of those around these days. A dog and all that goes with it, is the dog owners responsibility. Yours and yours alone. Clear up your poop!
