I'm racking my brain trying to understand what would motivate one to drop the bag and leave it. Here's where I've landed: Carrying a tied bag holding it from the top is annoying. Your hand is encumbered, and although the bag is not heavy, grasping it continuously for a long time is a nuisance. Holding it from the bottom is just yuck. So the assholes among us drop it when they figure they can get away with it.
With a simple slip knot I make a ring with the clean part of the bag that I then slide my pinky through and then tighten. Solves the problems above. My hand is mostly free to do whatever I'd like with no trouble. I have zero issue holding the bag throughout long 30-45 minute walks, after the dog poops 3-5 minutes in.
This is infinitely more detail than I ever thought I would write on how to carry a dogpoop bag. Now back to my day.
