Doggie Thong for Farting Dogs
A company called Flat-D Innovations, Inc. is selling a thong for dogs designed to make farts smell better.
Dubbed, "The Dogone", it's an activated charcoal cloth that traps the foul smelling odors from the passing wind.
It's washable and reusable. It uses elastic straps for flexibility, and suspender clips to make the thong adjustable. They also provide quick release when its time for poochie to do its business.
