Walking dogs in Battle Woods, I notice many disused pooh bags littering the walkways, and today on my walk counted 25 in a 40 minute circuit.
None were fresh, and I was told that walkers leave them on the rides to pick up later, but fail to do so.
Perhaps you could remind dog walkers that bagging up pooh and not using the bin provided is worse than leaving it in situ.
These bags are not bio-degradable, whereas their content is.
