Sniff out a spot in which to do your business

From Create Your Own Story

You put your nose to the grass and start to move along, sniffing the ground. Each spot you cross produces a different reaction: No... bad... not hard enough... not soft enough... too little grass... too much grass.... Then, BOOM! Your nose hits a spot on the grass that sends shivers of "rightness" down your canine spine. You get into position and... "YOU WORTHLESS MUTT!" an unseen person bellows. "HOW DARE YOU SHIT ON MY LAWN?!"

You look up. It's your crazy-mother-fucker-of-a-neighbor, Lou. And your on HIS LAWN. He'll kill you! You'd better think quickly.
