If you own a dog, you should know to pick up your dog's mess when you're out and about for a walk. But unfortunately, some dog owners don't.
One nine-year-old wants dog owners to know that doing so makes you a "lazy idiot" - and if he's responsible enough to clean up after his dog, you should be too.
One day a walker in the United Kingdom spotted a laminated warning note stapled to a wooden post and it was clearly left by someone who was fed up.
![Many Reddit users found the poster very funny and the majority agreed. Photo / Reddit](https://www.nzherald.co.nz/resizer/v2/47ZQL5C4G34LE5NCNF53G52Y7Y.jpg?auth=e29a17ef4d0a10f37adfd60a77ecdc438ba4d3db4667805b287ba7266a6b94bf&width=16&height=22&quality=70&smart=true)
The note read: "Clean up your dog poo it's disgusting. I hate it its always on my shoes and my brothers and sisters which then gets walked into our house [sic].
