Simple Design and Inexpensive
The Dogone - Dog Gas Neutralizing Pad is a comfortable and least intrusive means for deodorizing gassy discharges in a thong design. This will eliminate pet odors and dog odors from flatus or flatulence.
Uses our famous activated charcoal cloth (washable and reusable)! A starter hole is placed in the cloth in order to help you locate the suggested tail hole. Carefully measure tail and cut-out hole to proper size. Elastic straps are used for flexibility. Suspender clips are used to make the garment totally adjustable. They also provide quick release for allowing the dog out to do his business.
