Bag it and Bin it . . . but please don't Leave it!
Sadly there is a well meaning but misguided trend, to collect dog waste and then leave it 'to retrieve on the way back'. I hold up my hand to be counted amongst those misguided. Once, and only once, at the start of a long walk with no bins in sight, I bagged, and, placed in a wall crevice to deal with on our return . . . and yes I forgot. Some miles away I suddenly realised and I was devastated. I've never made the same mistake, because I never leave it behind.
