Dog poo on my shoe

Dog owners, please can you pick up your dog's poo. Today, I spent some time cleaning off the mess off my shoe. Although this is a nuisance, I am much more concerned about my daughter falling ill. I have heard that some dog poos contain worms that can cause blindness (if say a toddler rubs their eye with a dirtied hand). I am sure the dog owners that leave the poo on purpose do not understand the severe consequences. I do believe that if the dog owners are told of the dangers of dog poo, they will all clean it up. Should there be signs erected in the park that succinctly explains the consequences?

I would like to know why they do not clean it up in the first place. Are they too lazy? Do they think that the rain will miraculously wash it away so that their efforts will be pointless? If they have a garden, do they leave the poo lying about without cleaning it up? I cannot believe all the owners that do not bother cleaning up the mess in public places will act in the same way at home. So why the difference? Do they think that a public area is not their responsibility? Any way you look at it, they lack moral values.

There is such a thing called the Clean Neighbourhoods and Environment Act 2005. So it is against the law to leave the mess behind.
