I know what the gentleman is going through with his neighbor and dog. My front yard is a favorite relief stop for one of our dog walkers.
The master calmly waits as his dog sniffs around in circles and with a majestic stance Fido excretes. After a few scratches of dirt he walks toward the master, wagging his tail.
In a very diplomatic yell, I tell the master "Please! Would you have your dog try the open field two blocks down?" With a smile on his face the master replies, "When ya gotta go, ya gotta go!"
Need I say more?
