I think I agree with the OP. Paris is wonderful but the dog poo thing is an interesting problem. I honestly do not remember it being a huge problem in previous visits, but during our visit last fall it did seem like we had to watch every step. It may have just been that we stayed in an area we dont normally stay in etc. We did have a gross experience during check in at CDG. Lady walking her dog, it doing its business in check in area as she is dragging it and guy with luggage cart immediately behind her not seeing what is going on.....you get the picture. That sums up that trip pretty well.
