Tl:dr get an herbal dewormer. It works. One of my dogs would sometimes smell so bad that I would wake up in the night feeling like I was going to vomit from his stench. And my husband has run me out of the room more times than I could count. We used to have a "farting chair" that I would fuss at him to sit in on a bad night, it was at the other end of the room. Anyway, I used to worm my dogs with typical, vet approved chemical dog wormer. However, with my goats I have always used herbal when I can because we drink their milk, and their parasitic load can become immune to the chemical concoctions. Plus, the chemicals are only effective for a few types of worms and you end up having to dose them fairly heavily with multiple kinds of wormers to make sure you get them all. Usually it never addressed egg and sometimes not even early larvae stages. The herbal wormer takes care of all of it. So this last week I decided to do my dogs annual worming with the herbal wormer instead of the chemical crap in my office. Guess what? Their farts no longer smell. Also, about a month ago I had my husband do a ten day wormwood, black walnut, and clove tincture with me, and his farts no longer smell. It's interesting to note that in history, people knew they needed to worm themselves seasonally. Pharma wants you to forget that and believe that you don't need it, you're in a superior country and you couldn't possibly have parasites. I have noticed an increase in energy and I no longer crave soda, Dr pepper was one of my few vices. I haven't had one since I used the tincture. I never really had smelly farts so I can't claim that one. My sleep has been so much deeper and more dreams. And my thought processes seem sharper.
