Most dog owners don't carry plastic 'poop scoops' - they carry small plastic bags (often bio-degradeable) designed for the purpose

And, on the subject of man's relationship with dogs - one theory is that it is in no small way because of our long-standing association with canines that Man was able to develop speech and, thereby presumably, song. Apparently, in our cranial cavity, there is only space for us to have either the structures to enable us to make complex sounds OR the structures to enable us to have brilliant sense of smell. In evolutionary terms, because we had a close relationship with dogs, who came with a brilliant sense of smell, we utilised that and this in some way influenced our own evolution and meant that we were able to have a much more complex range of sounds available to us. So .... no dogs ... no folk festivals.
