What we heard this mornig

The door swings open, the resident Elf Lord appears holding her right shoe. "I have to clean off poop from my shoe!"
Elf Lord's Mom said, "Clean it off on the grass."
Elf Lord, "That was how I got dog poop on my shoe! The poop was hiding in the tall grass!"

The solution to this problem, clean the shoe on the grass.
This time use the grass in front of the house, where there is no dog poop, yet.
