In your red haze you didn't spot that I referred to the vast majority, not every single one. If you actually go around with your eyes open you'll see that you are the rare exception if your dog walks obediently to heel. There's a section of secluded footpath near Bude Canal that is known to the locals as dogshit alley. As for exposure to germs, sure. But I don't want you to get to choose my germs for me, thanks. And I'd rather they didn't include salmonella on supermarket trolly handles...
