I read a while back someone posting that they'd never heard of anyone being injured by dog poo, so why were people making such a fuss. I thought at the time it sounded suspect.
Here's a link to the lead story on BBC Manchester just now. www.bbc.co.uk/news/uk-england-manchester-11012044
Most dog owners do scoop the poop, but many don't. If you choose not to, don't hide behind the excuse its not doing anyone any harm. Its unsightly, unhygenic and potentially dangerous.
