I totally agree. I'm a dog owner but hate it when I come across dog poos regardless of where i am. I have left the house on the odd occasion having forgotten a bag, and been caught out by my dog, so I've used whatever I could find - a leaf, an old tissue, an old receipt, but I never just leave it there. Where there's a will, there's a way. Mind you, my dog is quite small, so that helps with poo size of course!
