I'm going to show my ignorance here but I'm not sure if every town has a town moor - in case they don't, the one near us is public land but farmers graze cows etc on it. So lots of cows but not private and not a farm!
Anyway, I walk The dog there everyday and always pick up her poo but I've noticed lots of other people don't . Then today, she pooed on top of a cow poo and I wondered what's the point picking it up when the place is covered in giant cow pats anyway.
So in short, if it was a naturally shitty area, would you still pick your dog's up?
