I live near a big beach and a marshes nature reserve. This is what I see happening. If a dog-owner thinks someone is watching, they will pick up the shit (though I have to question the mentality of anyone who isn't utterly repelled by the thought, or feel, of nice, warm, fresh dog crap like putty in your hand with only 10 microns of plastic separating you from the vileness of the ordure). If no-one is looking (or they think no-one is looking) they leave the shit where it is. A very large number of those who were forced to pick it up resort to chucking the scrotum-like bag of turdaceousness into the nearest hedge. The bushes round here are festooned with these abominations.   On the marshes, almost all dog-owners (seven out of eight on a snapshot occasion the other day) ignore the prominent signs to keep dogs on leads (so as not to disturb ground-nesting birds and so on). As dog-owners can't actually read, the council has even resorted to painting large dogs-on-leads signs on the footpaths. But as dog-owners also have visual-spatial problems, these don't work either. The dogs charge around the marshes with gay abandon. Every dog-owner thinks their little darling is the exception that does not require these reasonable restrictions. Walking on the beach, you can expect to be routinely accosted by dogs racing around hundreds of yards from their owners. In addition, you will nearly always come across some moron "playing" with their incessantly-barking dog on the beach and taking absolutely no steps whatever to curb the racket, which can be heard on the clifftops half a mile away. If you're at a festival, and your stupid dog is belting around outside your control, leaving piss and crap wherever little children play, and some bearded old git comes up to you to protest, don't worry. It won't be me.
