Even before the children’s book Walter the Farting Dog hit bookstores in 2001, the youngest members of society have known the truth. Dogs fart. They pass gas. The science-minded among us might refer to fart gas as ‘flatus’ (not to be confused with flautas, which might or might not give you flatus). Whatever you call it, dog farts can be silent but deadly, outrageously loud and stinky, even synchronized with a sneeze. In other words, dogs fart like us.
Capturing flatus is not to be taken lightly. In a section titled, ‘Collection and analysis of rectal gases,’ the researchers describe the outfit they rigged up to assess the farts. The main component is a jacket that looks like something companion dogs might wear in the rain, although this jacket comes with a sulfur gas detecting pump near the dog’s butt. To complete the suit, dogs wear disposable paper underpants to “protect the sampling device from external interference and help maintain proximity of the tubing to the anus.” Like I said, sort of like a rain jacket but with more farting.

But what makes dog farts stink? The researchers took their cue from human flatus, which contains “the atmospheric gases nitrogen and oxygen plus the non-atmospheric gases carbon dioxide, hydrogen, and methane, also referred to as fermentation gases.” Sulfur gases, particularly hydrogen sulfide, are behind our visceral response of, “EWWWWW! Who did THAT?” This distasteful smell is commonly associated with sulfur-rich foods like cauliflower or broccoli.
To explore the composition of stinky dog farts, the researchers took a two-pronged approach. First, the fart suit measured what the dogs were dishing out, specifically hydrogen sulfide concentrations in parts per million. Second, an Odor Judge joined the team. Yes, someone was assigned to assess the odor of dog farts (and although the study does not spell it out, I presume the job was assigned using the highly advanced method of Who Was Out Of The Room When The Decision Was Made). The Odor Judge (who I hope wore a special sash or top hat) whiffed “each flatulence episode and rated the episode on a 1 to 5 scale, where 5 represented an unbearable odor and 1 was noise-only with no odor. A rating of 2 represented a slightly noticeable odor, 3 was a mildly unpleasant odor, and 4 was a bad odor.” I give you science.

The Odor Judge’s assessments were then matched to real-time readings from the dog fart suit to uncover the composition of the most distasteful farts. As in humans, dog farts rated as more unbearable contained significantly more hydrogen sulfide than farts rated as less-noxious.

In an article by Vets All Natural in Australia, they generally advise switching your pet to a natural raw diet and experimenting with the ingredients to get a good mix. Repopulating the bowel using a pro-biotic supplement (live culture yoghurt or – more recently – a specific veterinary pro-biotic called Protexin) can be very effective. There are also a few natural ingredients that can lessen smelly flatulence like raw garlic, fennel, aniseed, ginger, or peppermint oil. Do consider the use of the Simply Pets Range which is registered, complete and should help with Flatulance. They also manufacturere a brilliant Pro and also Pre Biotic under their Simply Natural brand

Can we decrease the stink in dog farts?
Identification of the stink is merely a first step. Dog fart suit in hand, the researchers set out to investigate which compounds, if any, could render dog farts benign.
In a study of human farts (where subjects first consumed pinto beans “to ensure flatus output” – you can’t make this stuff up), charcoal and zinc acetate reduced fart stinkiness. Another study found that Yucca schidigera reduced stink-inducing hydrogen sulfide concentrations in dog poop. While those substances are available as dietary supplements, don’t use any of them without veterinary approval.
To investigate whether a combination of charcoal, Yucca schidigera, and zinc acetate would decrease the stink in dog farts, dogs got back in the fart suit. (The researchers call it a “flatulence-collecting system for dogs.” We’ll have to agree to disagree.) Then the dogs consumed treats containing the three ingredients.** The fart suit captured and measured hydrogen sulfide concentrations, while the Odor Judge rated the farts.
The treats with the three ingredients did the trick! While the number of farting episodes did not decrease, the stench of the emissions was less aversive. With the treats, farting “episodes rated as 4 (bad) or 5 (unbearable) were significantly decreased, and [the] percentage of episodes rated as 2 (slightly noticeable) was significantly increased.”

Make every day Dog Farting Awareness Day! Today is also National Dog Fighting Awareness Day. While illegal in every state, thousands of dogs are still forced to train, fight, and suffer every year. Let's end dog fighting.
** Additional note on dog farts: In the study, each fart-reducing treat contained “320 mg of activated charcoal, 2.5 mg of Yucca schidigera, and 17 mg of zinc in the form of zinc acetate dihydride.” Dogs were fed 1 treat per 11 lb of body weight. Jessica Hekman, DVM, MS and genomics PhD student adds, "We don't know if this stuff is safe to feed regularly. But that's one of the things good research does—provide ideas for future research. Like testing the safety of activated charcoal in anti-fart-stink dog treats."
- Hydrogen sulfide is behind the stink in stinky dog farts.
- Dogs eating treats containing charcoal, Yucca schidigera, and zinc acetate will continue to fart but will produce less-stinky farts.
- Veterinarians remind that a number of factors are behind a farting dog, including a sedentary lifestyle, eating quickly and swallowing air, as well as chowing down on difficult-to-digest food. More on farting dogs at Pet MD.
