foods for dogs with gas

Everyone farts.

You, me, your dog, and even your grandma.

But sometimes, toxic toots become problematic, particularly when your canine crop dusts constantly. If your dog’s excessive gas is clearing out rooms regularly, a change in diet may be necessary.

We’ll explain why your floof might be farting and share some of the best foods for dogs with gas or below.

In a hurry? Jump down to our recommendations for the best foods for dogs with gas!

What Ingredients Can Cause Gas for Dogs?

dog gas

Pups can have unique intolerances and sensitive stomachs, but some ingredients are known for commonly causing noxious gas in dogs. These won’t always stir up the stink, though if they’re in your tooter’s diet, you might want to take a second look at them.


beans give dogs gas

We all know the famous melody about these fart-inducing foods, and it’s not lying: Legumes really are a cause of flatulence. 

They’re rich in fiber, which has the uncomfy side effect of gas during digestion. The most fibrous legumes include white beans, lentils, garbanzo beans, kidney beans, and peas. These are commonly used as carbohydrate sources in grain-free dog foods.

High-Fiber Produce

broccoli for dogs

Fruity sources of Fido farts include apples, bananas, raspberries, bananas, and blueberries, while common veggie culprits are broccoli, potatoes, carrots, beets, and collard greens. 

Produce is an important source of fiber and essential vitamins in a balanced diet, but it’s worth double-checking the ingredients list if your dog is super gassy — you may even want to switch to a low-fiber dog food. You may want to reconsider what raw dog-friendly vegetables and fruits you’re offering too. 

Milk & Milk Products

milk makes dogs gassy

Many four-footers are lactose intolerant, making milk and other dairy products a serious source of flatulence in dogs. Digesting dairy is difficult for these canines and can even be painful.

It isn’t too common of an ingredient in dog food, but some frozen dog treats and other goodies may contain it. Luckily, there are dairy-free alternatives for your pup to enjoy without the belly burden.

High-Fat Meats

meat can give dogs gas

Meat is a critical source of protein in your dog’s diet. The best meat for your dog varies, but some protein sources contain more fat than others, making them richer and harder to digest, especially for sensitive stomachs.

The fattiest meats used in dog food include pork, beef, duck, and salmon. In contrast, turkey, chicken, lamb, kangaroo, and tilapia are some of the leanest meats. If you’re unsure which meat is to blame for your dog’s gas, try single protein source pet foods.

Whole Grains 

grains give dogs gas

Grain-inclusive dog foods provide vital nutrients and fiber for balanced nutrition, but the whole grains featured can lead to an uptick in gas in dogs.

Brown rice, quinoa, oats, cracked wheat, millet, barley, and corn are the most commonly used whole grains in commercial dog foods, and some dogs may digest one grain better than another.

If you suspect an ingredient in your dog’s food is summoning gas demons, work with your vet to craft an elimination diet to nail down the problem item and adjust your pup’s diet accordingly.

Why Do Dogs Get Gas?

why do dogs get gas

Occasional flatulence is a normal part of digestion as the body breaks down food, but excessive gas may signal something is off with your pup’s digestive process. In these cases, the ultimate source of the problem can be related to your pet’s behavior, health, or diet. 

Some of the specific reasons for toxic toots include:

Digestive System Issues

snoozing chihuahua

While farts are a normal part of digestion, an overabundance of gas can be a sign of digestive dysfunction. Unexplained flatulence can be caused by many things, including a stomach infection, colitis, enteritis, and pancreatic issues.

Canine gas that doesn’t seem to be linked to your dog’s diet or behavior needs to be investigated by a vet. 

Swallowing Air

dogs yawning

Known as aerophagia, swallowing air is common in canines. The excess air in the digestive tract needs to go somewhere, leading to increased backdoor bellowing. 

Dogs that eat or drink too fast may swallow extra air. Your four-footer will likely take in extra mouthfuls during play, too, creating an avalanche of post-exercise poots. Brachycephalic breeds (flat-faced breeds) are also known to suck down more air than others, making them some of the gassiest dog breeds

Stress or Anxiety

anxious dog hiding

A stressed or anxious dog may swallow more air than his pupper peers due to panting, and this can cause a surge in gas. Kenneled dogs are particularly prone to the problem, so if you notice more floof farts after picking up your dog from a stay, don’t be too surprised.

Eating Ingredients That Lead to Fermentation

fiber can cause gas in dogs

Fermentation is a healthy part of digestion where the gut’s bacteria breaks down food. Some ingredients (whole grains and fresh produce, especially) cause a more robust response in the body, increasing your dog’s gassy happenings.

Consuming High Amounts of Fiber

Fiber is an essential part of any diet, but the breakdown of fibrous foods during digestion has an unfortunate side effect: gas. And if you eat more fiber you produce more gas. High-fiber dog food is necessary for some dogs, but not all.

Consuming High Amounts of Fat

dog food fat content

Healthy fats support your dog’s skin, coat, brain, and beyond, but excessive fat in your pup’s diet can lead to major tummy trouble. Fat can be difficult for your dog’s body to process, leading to bloating and, unfortunately, gas.

Most dog foods aren’t particularly high in fat, so a common culprit here is feeding your floof people food.


Worms dogs get

An infestation of parasites in the gastrointestinal tract can lead to bloating and gas in dogs. Roundworms and hookworms are the most common parasitic causes of excessive gas in dogs. Other symptoms of parasites include bloating, diarrhea, and increased appetite.

Sudden Dietary Changes

dog eating treats

An abrupt change in your dog’s food can bring about gas and other unpleasant GI effects, like diarrhea.

This is why most dog food companies recommend slowly switching your dog to their brand. Many list a suggested timeline and measurements on the bag to avoid tummy troubles.

Poor General Health

If your dog’s body isn’t running in tip-top shape, he may struggle with processes like digestion and, in turn, experience excessive flatulence. Obese and inactive dogs are particularly prone to increased gas.

Food Intolerance

husky not eating

Not every dog’s stomach handles ingredients the same as other dogs.

Many dogs suffer from food intolerance, in which certain foods can cause your pup to struggle digesting a given food item, leading to bloating, gas, and an overall icky feeling. Food intolerances are often connected to proteins like chicken or beef. 

Note that food intolerances differ from food allergies. 

A food allergy involves the body mounting an immune response to a substance. Dogs with food allergies typically present with skin reactions, including redness and itching around the ears and paws. They may also suffer from breathing difficulties, swelling, vomiting, and diarrhea.

Food intolerances are much more common than food allergies in dogs, and typically involve gastrointestinal symptoms.

People Food

people food for dogs

Human food is the apple of many dogs’ eyes, but it can lead to wicked farts. Our cuisine has all sorts of ingredients that the average canine system isn’t used to encountering, which can stir up some real booty bombs.

People food also tends to be higher in fat – a problem we covered above.

Small Intestinal Bacterial Overgrowth (SIBO)

pooping poodle

As the name implies, SIBO is an oversupply of bacteria in your dog’s small intestine. Excessive gas and diarrhea are the most common symptoms. SIBO can be idiopathic (meaning no known cause) or a comorbidity associated with other health conditions, such as malabsorption or pancreatitis, among other possibilities.

Microbial Flora Imbalance

dog gut flora

Your dog’s digestive system is full of good and bad bacteria that function like an assembly line – each has a unique job that keeps business moving. If one part slacks off or goes into overdrive, it can throw off the rest, potentially causing gas, diarrhea, and other uncomfortable symptoms. 

Opting for high-quality dog food with probiotics can maintain order, but always check with your vet first.

Inflammatory Bowel Disease (IBD)

pooping dog

This chronic condition strikes the intestinal tract of dogs, leading to ongoing inflammation and discomfort. Common symptoms include flatulence, vomiting, and chronic diarrhea. Left untreated, it can lead to weight loss, malnutrition, and other serious problems.

Other Gas-Stopping Strategies for Dogs

dog gas remedies

Preventing your pupper’s excessive gas may require a multi-pronged approach, particularly if diet alone doesn’t fix the issue. Try some of these tips to stop your dog’s stink in its tracks:

  • Slow down meal times. A slow-feeder dog bowl is worth its weight in gold if your canine is a speed eater who gobbles down lots of gas-causing air while dining. You can also feed your dog by hand or make dinner time into a game if you prefer. 
  • Feed smaller, more frequent meals. Eating too much food at once can lead to gas as the ingredients break down in the stomach. Offering your pup food multiple times a day in smaller portions can sometimes prevent extra gas from popping out.
  • Check all treat and chew labels. Your pup’s goodies may be to blame for his wicked wind – not his food. Examine the ingredient lists of his favorite snacks to see if they’re causing the problem. High-fiber treats are prime suspects, along with those who use artificial flavors and other additives that can lead to an upset stomach.
  • Eliminate table scraps. We know it’s hard, but people food is often too rich for dogs with a sensitive stomach and just isn’t worth the trouble for the treat. Better, safer alternatives don’t risk stinky surprises, including tasty DIY dog treat chews.
  • Cut down on treats. Like your mutt’s main course, too many treats at once can lead to gas issues as his body breaks down the extra offerings. A small goodie here and there won’t hurt, but multiple treats throughout the day add up.
  • Try probiotics. Dog probiotic supplements or yogurt may calm your canine’s tummy woes, but only introduce them with your vet’s OK. They can exacerbate the issue in some instances. 
  • Walk out the gas. A daily walk or two lets your dog release his chemical carnage outdoors instead of in your house and helps keep him trim. The exercise itself may also help – pudgy pups may be cute, but extra pounds can be the source of your doggy’s digestive issues.
  • Talk to your vet. If no changes in routine seem to help your dog’s gas problems or if they come on suddenly without an obvious cause or come with other gastrointestinal issues, it’s time to reach out to your vet to rule out underlying causes like intestinal parasites or illness.

Dog Foods for Dogs with Gas: FAQ

Still have some questions about dog toots and the best ways to eliminate them? We’ve answered some of the most common ones below to help clear the air.

What dog food is best for gassy dogs?

The best food for a gassy dog will depend on a variety of factors, but we think Nom Nom is one of the best first-line options, while Purina Pro Plan Sensitive Skin & Stomach is a good budget-friendly option.

What foods make a dog less gassy?

Foods that have minimal to moderate fiber content are often helpful for gassy dogs, as are foods with probiotics.

How do I stop my dog from being gassy?

It depends on the reason your dog is gassy. It may require a change in food, or — if your dog is gassy due to a medical problem — medications may be necessary.

What can I give my dog for gas pain?

If you are worried your dog is suffering from gas pains, you should contact your vet immediately. The pain may very well simply be from run-of-the-mill gas, but it could also be a symptom of bloat.

However, once your vet has cleared your dog and confirmed that his pain is no cause for concern, he or she may recommend giving Gas-X to your dog.


Does your dog enjoy any of the foods on our list? Is there another high-quality food that helps him avoid gassiness? Does he just have a sensitive stomach in general? Share with us in the comments!
