Here is what I saw out the window while eating breakfast:
Little dog, doing its "duty" in my mom's garden. Little dog's owner leans over with a Tim Horton's paper coffee cup, and scoops "duty" in with the lid, closes it up, and continues on the walk.
Huzzah! Camouflage poop sac! No more dangling baggy you can hide from no one! Brilliant!
Except she kinda gave it away by holding the cup at arms length for the rest of her walk.
