I think my life would have been complete without ever encountering the words "thong" and "gassy discharges" together--but fate has another plan for me. The Dogone - Dog Gas Neutralizing Pad is a "means for deodorizing gassy discharges in a thong design."
The pad comprises a washable and reusable activated charcoal cloth, elastic straps, suspender clips and a "starter hole" for your pooch's tail. It also comes in small, medium and large.
A word of warning, though. When flatulence rears its stinky head, you can't point to your thong-wearing dog and blame him anymore. You win some, you lose some.
