There are a million jokes that can be made about dog farting, but if you have a pet who is an excessive farter, the smell or sound might be wreaking havoc on your personal life. Plus, in some instances, the answer behind what makes dogs fart such foul-smelling gas could be that their health needs attention. Smelly wind may be the butt of many jokes, if you’ll pardon the pun, but if it’s not normal for your dog or it’s accompanied by sickness, diarrhoea or weird things like yellow poop, it might not be such a laughing matter.

Or, on the other hand, your dog might just be a super-farter who doesn't mind stinking you out. Hey, we all have our special talents; this just might be theirs.

If you've ever noticed that your dog farts a lot, or have had to deal with the embarrassment of it happening when you have guests over, then this guide is for you. Here's how you can determine what may be causing the noxious smells and whether or not the gas warrants a prompt visit to the veterinarian.

What Makes Dogs Fart?

There are many reasons why your dog may be extra flatulent. Some common reasons include changing their food, gastrointestinal illness and nutritional disturbances, such as a food intolerance.

Another cause can be the type, quality and quantity of ingredients in your dog's food as they influence the amount of gas formed in the intestine. When bacteria in the colon ferment fibre or poorly digested proteins and carbohydrates, gas is produced. Pet food containing certain oligosaccharides (found in ingredients such as soybeans, beans, chickpeas and lentils) tend to produce large amounts of gas in the intestine.

However, there are other, less common, reasons your dog might be stink-bombing your family. Does your pooch eat too fast? The American Kennel Club (AKC) reports, "It is widely believed that aerophagia, or increased swallowing of air, can lead to gas in dogs. Greedy eaters that wolf down their food and brachycephalic breeds are at an increased risk of swallowing more air than normal, which can lead to gas down the line, so to speak."Blonde pug with face buried in a metal dog food bowl.

But, Seriously. My Dog Farts A LOT.

Passing gas is as normal for dogs as it is for humans. However, it's important to pay attention if you're noticing a significant increase in your dog's flatulence.

What you may view as "too many farts" could be an indication that your pet is experiencing gastrointestinal issues. Additionally, farting could be a sign of intestinal parasites or problems with the pancreas, says the AKC.

Any major change in a pet, even if it seems as silly as farting, warrants a trip to the veterinarian to ensure they aren't experiencing a serious problem. If gas is accompanied by poor appetite, diarrhoea, vomiting, weight loss or behaviour changes, it's definitely a good idea to give your vet a call.

How to Stop the Farting

If you think your dog farts a lot and are wondering how to reduce it to a more appropriate amount — you're in luck. If your veterinarian is able to help you identify the cause of the excess gas, you might be able to reduce some of the farting. For example, if you feed your dog cheese as a treat, but your veterinarian determines your pet is sensitive to dairy, simply eliminating it from their meal plan can drastically decrease their flatulence.

Just as you can't control another human's gas passing, you can't completely control your pet's either, but what they eat could offer your nose a little relief. Dog foods that contain high levels of protein or poorly digestible protein sources often produce more odorous farts. Ingredients such as broccoli, cabbage, cauliflower and brussels sprouts can also be fermented and produce sulphur containing gases that lead to smelly farts.

Importance of Nutrition and Its Role in a Dog's Flatulence

Speaking of what your dog eats, their everyday nutrition plays a huge role in their digestive health that, in turn, affects how much gas they might be passing. Intestinal bacteria can ferment undigested proteins and produce sulphur-containing gases. With that, a properly balanced dog food with the right nutrients can help promote healthier digestion. Be sure to ask your veterinarian to recommend a healthy dog food. Additionally, for dogs that have been diagnosed with a disease that causes poor digestion or malabsorption of nutrients, these conditions may be associated with bloating and flatulence. For these dogs, veterinarians can recommend dog foods specially formulated to support the dog's GI tract health. Be sure to ask your veterinarian if one of these therapeutic pet foods is a good option.

Now that you know what makes dogs fart, you can hopefully put an end to — at least some of — the stink bombs in your house! Take a closer look at your dog’s food and see if there is anything that might be putting their digestive system out of whack. And remember, a quick visit to the vet can always help you determine how to proceed in the best interest of your pet's health.
