I think I've only ever seen a dog owner clean up after their pet once, but then again I'm terrified of dogs so I tend to not stick around. People seem a lot more courteous and conscious of it these days though. If I saw someone not clearing up after their dog, then I'd probably pick it up using a plastic bag, follow the owner home, then put it up the exhaust pipe of their car like Eddie Murphy does in Beverly Hills Cop. If they didn't have a car, I'd stick it in an envelope and mail it to them, but in a big box full of packing foam so they'd have to root around for it with their hands*. If you don't want this happening to you, then I suggest you pick up the Clean City Toiletry Bag. The purse contains a roll of plastic bags and a little pocket for your house keys, so you can take your dog for a walk and not worry about the repercussions.

Get one now from Vincon for ($10.30/£5.30).

*Disclaimer: I am way too lazy to ever do this. The most you'll get from me is a disapproving look. Popgadget are in no way responsible if you receive a box of dog muck in the mail.
