Why Dogs Get Gassy

Flatulence is the term for excessive gas production in the stomach or intestines. Air or gas ejected via the anus is referred to in medicine as flatus.

What causes flatulence in dogs?

A change in diet or the dog eating something rotten are the two most frequent causes of flatulence (dietary indiscretion). The majority of cases of persistent flatulence are brought on by the dog’s nutrition not being properly broken down. These inadequately digested diets result in increased colonic fermentation and consequent gas production. Foods like soy, peas, beans, dairy products, high-fat diets, and spicy foods are all frequently linked to canine flatulence. Being lactose intolerant, the majority of dogs and cats will develop flatulence and/or digestive discomfort if given milk or dairy products. If a dog is receiving a premium feed but is still experiencing flatulence, a maldigestion issue with either poor digestion or inadequate nutrient absorption from the diet should be investigated.

“A change in diet or the dog eating anything rotten (dietary indiscretion) is the most frequent cause of flatulence.”

Flatulence is more likely to occur in dogs who swallow air while eating, especially those who eat quickly. Regardless of nutrition, dogs who are overweight, obese, and inactive are more likely to have chronic flatulence.

What are the clinical signs of flatulence?

The most typical clinical symptoms include excessive gaseous sounds or rumbling from the belly, minor abdominal discomfort, slight stomach distention or bloating, and gas expulsion from the anus, with or without odor (borborygmus). Clinical symptoms of underlying malassimilation issues in dogs include loose stools or diarrhea, vomiting, and weight loss. These conditions result from the gastrointestinal tract’s inability or impairment to provide the body with nutrients.

How is the cause of flatulence diagnosed?

Clinical symptoms and medical history are used to make a diagnosis. The following common causes should be ruled out:

  • increased air swallowing (aerophagia)
  • Obsessive or gluttonous eating
  • a respiratory condition
  • shortly after workout, eat
  • breeds with flat faces or brachycephaly
  • Discretion in diet
  • diets rich in beans, peas, or other legumes
  • high-fermentable-fiber diets, such as those containing lactulose, psyllium, or oat bran
  • rotten food
  • milk and other dairy goods
  • rapid dietary change
  • spiciness and additives in food
  • inflammation of the colon (IBD)
  • an increase of microorganisms in the small intestine (SIBO)
  • tumors
  • Inflammatory bowel disease (IBS)
  • parasites of the intestine
  • enteritis
  • pancreatic exocrine insufficiency (EPI)

Fecal examination and/or culture, rectal cytology, blood and urine tests, including specialized ones like those for trypsin-like immunoreactivity (TLI), serum cobalamin, and serum folate, abdominal radiographs, abdominal ultrasound, and intestinal biopsies are examples of diagnostic tests that can be performed.

How is flatulence treated?

Based on the diagnosis, a diet adjustment is frequently part of the treatment. Diet recommendations call for a low-fiber, high-fat diet that is highly digestible. As a result, less food must be ingested and digested before it reaches the pet’s intestines. Carminatives (drugs to treat flatulence), such as zinc acetate, Yucca schidigera, or probiotics, may be used as part of medical treatment. For dogs who eat quickly or become overly excited, small, frequent feedings are advised. Your pet’s treatment strategy will be described by your veterinarian.

What is the prognosis for resolving flatulence?

Most people with straightforward situations benefit greatly from dietary and way of life modifications. It is crucial to stay away from any offending food products and substances once they have been discovered.

What can I do to help my dog’s gas?

What transpires, then, when this occurs too regularly or when your dog’s gas unexpectedly makes the space feel empty? The truth is that passing gas can actually signal a significant issue that needs medical attention, especially when it occurs in conjunction with other symptoms including bad odors, diarrhea, and more. “According to Dr. Amanda Nascimento, DVM, the NHV’s Natural Pet’s in-house veterinarian, stomach gurgling (belly noises) and unpleasant odors might undoubtedly be a symptom of a problem for your pet.

Any breed of dog can experience flatulence, though it is more prevalent in brachycephalic dogs including Bulldogs, Pugs, Boxers, and Boston Terriers. “The creation of gasses may be more noticeable in brachycephalic breeds or in animals who ingest a lot of air when they are inhaling or eating, Nascimento continues.

Force Your Dog To Slow Down While Eating

There being too much air in the stomach is one of the most typical reasons of flatulence. This might be the result of them swallowing a lot of air, which Nascimento claims is typical of dogs who eat too quickly.

Try moving to smaller meals spread out throughout the day rather than two large ones if you have a dog who just takes everything in his bowl in a matter of seconds. Your dog will eat considerably more slowly if you use a slow feeder dish or a treat-dispensing toy when feeding them.

Avoid Giving Your Dog Table Scraps

Dogs are curious animals who rely on their keen sense of scent for direction. Try to avoid leaving food scraps lying around, and make sure your garbage bags are tied tightly and hauled outside if you frequently discover trash bags torn open or if your dog is skilled at emptying the table after you stop eating. Gas and flatulence can be brought on by leftovers and stale or rotting meals.

Change your dog’s diet slowly (avoid fart-causing foods)

If you are changing your dog’s diet, try to make little changes at first so they can become adjusted to the new diet. Giving dogs high-quality food to promote good digestion is incredibly important. Some foods are more likely than others to make you feel bloated. Brussel sprouts, cauliflower, and broccoli are some examples. Although you can give your dog small amounts of these items as wholesome, nutritious treats, try to avoid doing so.

Try a food elimination plan to rule out allergies

Gas in dogs might result from food allergies. It is beneficial to follow a food elimination regimen to discover potential triggers if you have worries about a gassy dog. You can eliminate these meals from your dog’s diet and replace them if you can identify the foods that give dogs flatulence. Keep a meal journal for your dog, phase out all the items they typically eat, and then only feed them two essential nutrients (one protein and one carbohydrate) that they haven’t previously consumed. Take down and record their responses as well as any changes to their bowel habits.

Is a dog’s frequent farting normal?

No one wants to deal with dog farts, whether they are deadly silent or startlingly loud and odorous. These farts are not only humiliating for you and your visitors, but they may also be a sign that your dog is in agony from too much gas. While your dog may occasionally release gas, this is a normal and unavoidable aspect of life; nevertheless, excessive gas is not.

You should consult your veterinarian to find out what’s causing your dog’s offensive gas as there are several potential causes, including gastrointestinal problems and food intolerance. Here, we examine the potential causes of dog farts and provide solutions.

Why Does My Dog Fart So Much and Stink?

Dog farts can have a variety of causes, but most of them are similar to human causes. Following a meal, digestive tract bacteria convert the food into nutrients the body can use. Stinky hydrogen sulfide gas, a byproduct of certain meals being digested in the colon, is released during this process. When the gas gets trapped, your dog can only fart to release it.

When they eat and drink, some dogs also have a tendency to swallow a lot of air, particularly speed-eaters and breeds with short-nosed brachycephalics like Pugs, Boston terriers, Shih Tzus, and Lhasa Apsos. This air they swallowed is likewise let out through farting, just as the gas that builds up in their digestive system.

So, is frequent farting in dogs normal? Everyday gas is typical, but if you feel the need to protect yourself from your dog with a gas mask, something is wrong. This is especially true if your dog has just started farting, has diarrhea, or has blood in their stools.

What causes my dog’s foul-smelling gas?

For dogs, the odd “toot is typical (and people). However, living with persistently gassy dogs who can fill an entire room with their offensive emissions is not enjoyable. In addition to having a negative impact on your relationship with your dog, excessively foul-smelling dog flatus (i.e., gas emitted from the anus, called farts) could be an indication of a potentially serious issue.


Many of the same reasons that humans pass gas also apply to dogs. One of the main ways that gas enters the stomach while eating is through swallowing air. The majority of this air, though, is belched out, and relatively little enters the intestines.

The main source of gases in the intestines is normal digestion (more on that coming up). The transfer of gases from the blood into the intestines is a third source of gas in the gastrointestinal (GI) tract. Intestinal gases must exit the body in some way; some are passed through the anus and back into the circulation.


The intestinal microbiota, a term used to describe the billions of bacteria, fungi, viruses, and other single-celled creatures that inhabit the GI tract. The digestion and fermentation of dietary components, especially those that cannot be processed in the small intestine, is one of the many jobs performed by this microbial population.

Food fiber and complex carbohydrates are fermented by bacteria in the large intestine, producing gases such carbon dioxide, hydrogen, methane, nitrogen, and methane. Once more, a certain amount of gas production is typical and poses no threat.

However, excessive flatus frequently stems from dietary factors, such as a fast change in diet, a diet that is unsuitable for a dog’s digestive tract, nutritional error, or food manufactured with subpar ingredients. Large volumes of intestinal gases are probably produced in these circumstances. Dogs lack the digestive enzymes required to split or break down specific fibers or complex carbohydrates into smaller, absorbable molecules when they are present in meals. Instead, the large intestine’s bacteria ferment these nutrients, creating a lot of gas.


Five gases without odor More than 99 percent of the gases passed as flatus are composed of nitrogen, carbon dioxide, oxygen, hydrogen, and methane. The other 1% is made up of a combination of sulfur-containing gases, such as hydrogen sulfide, which gives flatus a rotten-egg stench. Numerous amino acids containing sulfur are necessary for good health, making sulfur a significant mineral. However, excessive sulfur from a diet high in meat or protein can be the reason for particularly foul-smelling gas. Red meat, eggs, soybean, alfalfa, beans, peas, and lentils are among the items used in dog diets that are high in sulfur.


Dogs who have sensitive stomachs or real food allergies are more likely to experience frequent, nasty flatulence than other dogs. However, a more serious underlying reason may also be indicated by foul-smelling flatus. Any GI condition that impairs the small intestine’s capacity to digest and/or absorb nutrients might result in an increase in large intestinal gas output and gassy odors.

The following medical conditions can also be linked to an increase in dog flatulence:

  • Colitis of the bowels
  • Overgrowth of bacteria in the small intestine
  • gastrointestinal parasites
  • Intestinal inflammation (enteritis)
  • A parvovirus infection
  • Pancreatic dysfunction (exocrine pancreatic insufficiency)

In addition to having too much gas, the majority of these medical problems also have symptoms including diarrhea, weight loss, vomiting, or changes in appetite. Make an appointment with your veterinarian if your dog has other symptoms in addition to being gassier than usual.


Before you grab the gas mask or find dog farts amusing or disgusting, you should be aware that there are steps you can do to lessen your dog’s excessive and offensive gas. The objective is to alter the diet in a way that causes less gas to be produced by microorganisms fermenting undigested food.

The greatest strategy to lessen your dog’s excessive tooting is to consistently offer him high-quality dog food. Selecting a highly digestible dog food is one of the first tasks. Giving a highly digestible food limits the amount of nutrients that are available to intestinal bacteria for fermentation that are not fully or incompletely digested. On the pet food label, search for the phrases “well digested” or “low residue,” but be mindful that they aren’t always there.

Avoid feeding your dog meals that include more protein than is actually necessary. However, protein digestibility is still crucial. Some dogs may benefit from switching to a meal with different protein sources.

Talk to your veterinarian about changing your dog’s food to a sensitive stomach formula, such as Diamond CARE Sensitive Stomach Formula for Adult Dogs, if you believe your dog has a sensitive stomach. Specialty diets, like those created for dogs with sensitive stomachs, are made to be quickly and easily digested. They frequently contain just one or two types of protein and carbs.

Get your dog moving at last! Sedentary behavior has been linked to both human and canine flatulence, according to research. Within 30 minutes of eating, walking your dog outside encourages bowel movement and aids in the elimination of intestinal gas.

Why is my dog suddenly having so much gas?

Everything is well as you and your family are relaxing and perhaps watching TV while the dog sleeps at your feet. Then, suddenly, a foul smell permeates the space and it feels like a mustard gas attack. Everyone starts coughing and even cleaning their throats to show their irritation.

The dog looks up at the ruckus and appears to be the only one taking pleasure in it, unaware that he is the one who caused it.

Congratulations! You’ve just experienced canine flatulence, which is notorious for being silent but lethal and has killed several dog owners before you. The “Anatomical fact: quiet portion. Since a dog’s rectum typically hangs horizontally, their sphincter doesn’t need to be as tight as a human’s; because our rectums typically point straight down, we need the added security.

Most dogs can pass gas with little to no noise because a looser opening results in less resistance. Dogs so rarely give an auditory warning of an approaching storm, unlike a human doing the same.

Inspire by his earlier discovery of tablets that will accomplish the same thing for people in the aromas of ginger, chocolate, or roses, a French entrepreneur named Christian Poincheval is now marketing a powder that he claims can make pet flatulence smell like flowers. It is therefore feasible to make your dog a walking air freshener, but what if you want to cut down on the frequency and virtually eradicate the odor?

Similar to humans, dogs have large intestines that are home to a variety of bacteria that consume the food we eat and generate gas. The smell of that gas can be either pleasant or horrific depending on its makeup; sulfur is one particularly foul offender. A dog’s propensity for farts can also vary depending on other circumstances. These are a few of the reasons.

Some foods are more prone than others to give a dog a flatulence attack, just like people with the famed beans. Beans, cauliflower, cabbage, and soybeans are foods to stay away from.

Dogs are not fully accustomed to digest vegetable fiber, unlike humans, thus eating low-quality food that is packed with soy or corn fillers might also result in issues.

Finally, if your dog consumes dairy products while being lactose intolerant, this may result in more frequent and unpleasant farts.

Although this type of flatulence is rarely as offensive, ingested air is a significant source of intestinal gas in both dogs and humans. A lot of air will be swallowed by your dog if they eat too quickly, and there are only two routes for it to exit their body: either through a frontal burp or a backward belch.

Put a ball in your dog’s bowl or purchase a slow feed dog dish, which has raised obstacles in it to encourage your dog to eat more slowly, if they eat too quickly.

Anyone who owns a boxer can attest to the fact that some breeds are more prone to farts than others. This sometimes presents a problem for dogs with brachycephalic or “pugs, bulldogs, Pekinese, and Boston terriers have pushed-in faces; as they breathe via their lips, they naturally ingest a lot of air.

The German shepherd, mastiff, Labrador retriever, Doberman pinscher, poodle, and beagle are further breeds that are prone to gassiness. If you own one of these breeds, it might not be a terrible idea to use that powder to give them a pleasant aroma.

Your dog may have a medical issue if they become suddenly very gassy. Pancreatitis, liver illness, and food allergies or intolerances, particularly to lactose or grains, are examples of potential causes.

It’s time to take your dog to the vet if he or she is experiencing excessive flatulence along with other symptoms like vomiting, diarrhea, or loss of appetite.

It’s a good idea to ask your veterinarian about the possibility of prescribing a broad range intestinal wormer for your dog every three months because parasites, such as intestinal worms, can also exacerbate the issue.

There are things you may do if your dog frequently ejects you from the house.

Give your dog the best food you can afford to buy, one that is loaded with protein and free of fillers like corn, wheat, or soy.

Both canine probiotics available from your veterinarian and yogurt with a live culture can help change the balance of bacteria in your dog’s intestines, resulting in less volatile gas generation.

Avoid feeding your dog human food as well, especially if it contains fat, sugar, or a lot of carbohydrates. Also, eat fewer dog treats because more food to digest means more waste to excrete.

However, always keep in mind to alter your dog’s diet gradually. They do not adjust to new meals as rapidly as people do. Limit the diversity as well. Constantly switching between chicken, beef, lamb, and so forth can make your dog gassy.

Exercise is not only essential for a balanced dog, but it can also support a healthy digestive tract. Exercise encourages the intestines to function effectively, and as digestion becomes more effective, less gas will be produced as a result.

It is much preferable to be outside with your dog than to be inside when she lets loose with a barn burner, so allow plenty of time for the walk and outdoor fun. Don’t worry if it doesn’t work at first.

In order to help your dog lose weight and create a healthy balance of gut bacteria, work with your doctor to construct a diet and exercise plan. Obesity can be a contributing cause in excessive flatulence in any breed.

A dog’s gas doesn’t have to smell like a burning sewage treatment plant or a slaughterhouse; neither will it ever naturally smell like roses and rainbows. You should be able to take the “deadly” out of “silent” and lower the loudness and fragrance with a few straightforward actions. Your dog and nose will appreciate it.
