Because my 17 year old pit bull just fell and shat himself with diarrhea. On the carpet, of course. I cleaned him and the mess as best I can until a carpet cleaner comes, and we're headed to the dog wash now, but it still smells like shit in here. Literally. Candles and open windows aren't helping. You guys, I had to do *SOMETHING* to try to mask the smell!! So now it smells like weed and candles. And shit.
