Has Fido’s flatulence become a problem? When friends and family evacuate the room due to the dog’s gas, it may be time to ask, “Why does my dog fart so much?” Passing gas is normal and a healthy bodily function for humans and their four-legged friends.

Dog farting happens to release gas from the digestive tract, namely the stomach, intestine, rectum, and colon. The body absorbs some of the digestive process’s smelly remnants, but it can cause discomfort in the abdomen and digestive passages when there is too much gas. Farting is a painless, sometimes musical, way for this gas to escape.

Okay, so it is normal, and there is nothing you can do to eliminate a pungent whiff passing through your home from time to time. However, when it’s excessive or dangerously potent, it may signal other problems. Keep reading to find out what causes extravagant canine flatulence. We give you some ideas on how to treat it and explain when you should be concerned.

Why Does My Dog Fart So Much? Common Causes of Dog Farts

why does my dog fart so much

There are several reasons why your dog’s farts are becoming more frequent.

Swallowed Air

One of the most common reasons your pup might be having gas problems is because they swallow a lot of air during mealtime. This happens when they wolf their food down within seconds. Dogs do this for many reasons; it could be because they’re a hyperactive breed, or they’re competing with doggy siblings. Brachycephalic breeds with flat faces are also more prone to passing additional gas. Air in, artillery out. 

Human Foods

Yup, sorry, but your table scraps may be the culprit in the farting debacle. Even though those puppy dog eyes may be convincing, handing human food to your dog isn’t worth the thanks they may give you. You’ll be thanked with toots and a tail wag. 

Table scraps that encourage farting include:

  • Spicy foods
  • Beans, especially soya beans
  • Sugar
  • Fruits
  • Milk products
  • Peas
  • High-fat food

Moderate amounts of these foods will be harmless, but if your furbaby gets their jaws on a whole bowl of peas, then you have some issues coming your way. Sing after me, “Beans, beans, they’re good for your heart, but the more you eat, the more you fart.” Stick to dog food and small amounts of natural foods that are free of butter, oils, or spices. 

Low-Quality Dog Food

Excessive farting is usually linked to a dog’s diet. Poor quality dog diets are damaging and often difficult to digest. When enzymes don’t fully digest a meal in the intestines, then bacteria in the colon convert the remains into hydrogen and carbon dioxide gases. The result is an extremely stinky fart. 

High-fat diets or high fiber foods are usually the cause of digestive issues. Filler ingredients like corn, wheat, or soy can cause a reaction, but there is also a likelihood that your pet has an intolerance to another ingredient in their every-day food. Carrageenan is a bothersome filler in canned or wet dog foods. It’s used to thicken and fill the product but has no nutritional value.

A Sudden Change of Diet

Escaping harmful ingredients or ones that cause an allergic reaction in your dog is a great idea if the tooting has gotten out of control. Good quality dog foods can cater to your dog’s needs and exclude harmful fillers. However, changing their diet will not fix the problem immediately. It’s essential to introduce new foods gradually so that their stomachs can adjust to the new diet. 

Mixing old and new food, gradually increasing the percentage of new food, will be the best way to do this. By doing this, the flatulence will hopefully subside to a tolerable amount. 

Too Much Protein

A diet that is rich in meat can cause very smelly gas performances in your home. Protein is great for pets, and they need it. You want to choose food that is high in protein. But too much of a good thing isn’t always a good thing, and when your doggo is eating too much meat, especially red meat, the sulfur in the steak can cause stinky farts.

Food Poisoning

While food poisoning is a serious topic for another article, slight poisoning can affect your pet too. Should your furbaby love eating the trash, your baby’s diapers (yes, my hound has done this), or the dead bird in the garden, the toxic and fermenting item that caught their fancy can cause an upset stomach. 

Recalled dog food, raw food, compost, and garbage should be out of reach if your dog enjoys stinky snacks. If signs of poisoning occur, such as vomiting, diarrhea, reduced appetite, lethargy, and dehydration, call your veterinarian immediately. 

Food Intolerance or Sensitivity

food intolerance can cause dog farts

Food allergies are common in dogs. If your dog is lactose intolerant, then eating dairy products can cause excessive gas. Food allergies upset the digestive tract and can cause all sorts of unwelcomed issues.

When your pet is exhibiting signs of intolerance, check their food for the usual allergens, it could be the cause of their toots. A sensitive stomach can also rebel by expelling gas.

Intestinal Parasites

We know parasite prevention is not at the top of your priority list, but it’s important to de-worm the whole family. Humans and furry friends all need their treatments, and putting a reminder on your family calendar can save you having to deal with an infestation. Intestinal parasites cause nasty symptoms such as diarrhea, scooting, distended abdomen, weight loss, dull coat, and decreased activity. Oh, and let’s not forget flatulence!

Speak to your vet about a parasite prevention plan for your furbaby. 

Health Issues

No one wants to hear that their dog has health issues. There is the rare occasion that excessive canine flatulence points to diseases. Gastrointestinal diseases in dogs that commonly list flatulence as a symptom include:

  • Irritable bowel syndrome can cause chronic inflammation and discomfort in your dog’s bowels. IBS can be brought on by a number of things and is usually related to intolerances. 
  • Inflammatory bowel disease is caused by the excessive growth of bacteria in the small intestine. The inflammatory cells cause changes in the digestive tract and limit the natural absorption of their dog food. Medication and diet changes are the best way to respond to inflammatory bowel disease. 
  • Exocrine Pancreatic Insufficiency develops when the pancreas is unable to execute the production of digestive enzymes and insulin.

Dog Flatulence: When to Be Concerned

If horrible symptoms like weight loss, vomiting, diarrhea, bloody stool, lethargy, or any other puzzling symptoms are inflicting your pup, it is time to have them checked out by the vet. Pet owners know their pup best, and if they are not acting themselves, then a wellness checkup is a good idea. Take note of any symptoms that you’ve noticed so that you can give your vet an exact list of the problems.

How to Stop Dog Farting

Put on your gas mask and get to the bottom of your dog’s farts. Often incessant gas expulsion only needs a few lifestyle tweaks to rectify it. 

1. Change Their Diet

The fact that poor diet is the most common cause of dog farts makes it a relatively easy problem to solve. Changing their food to a good quality brand that excludes useless filler ingredients or common allergens is a great start.

Whether you try a vegan doggie diet or homemade organic meals, consult your veterinarian to determine what ingredients you should avoid. Make sure their food is rich in all the nutrients that they need for a healthy life. 

2. Introduce a Slow-feeding Method

Fast eating can cause bloat or choking, as well as farts. To stop your dog from inhaling their meal, you can introduce a snuffle mat or slow-feeding dog bowl. This will reduce the amount of air that they’re inhaling and hopefully lessen the frantic farting. 

3. Increase Activity

Exercise aids healthy digestion in the body. If your lazy pooch is particularly tooty, then make sure you get them out for a run or play session before their meal. Regular exercise can strengthen your dog’s digestive tract and help release unwanted gas while you’re outside. And it is good for you too!

Probiotics and Prebiotics for Dogs

Once your veterinarian has ruled out sinister issues, and you’ve made any necessary diet changes, adding supplements and probiotics to your dog’s diet will be a good next step.

Probiotics are helpful strains of bacteria that add to the naturally occurring bacteria present in the body to promote a healthy gut. Prebiotics come from plant fiber and feed good bacteria to promote gut health and a healthy immune system.

Speak to your veterinarian about probiotic supplements that can help your pet. If you prefer to go the natural route, there are natural prebiotics from which to choose. By adding them to your dog’s diet, they may do the very thing you need them to do – reduce dog farts. 

Here are some natural pre and probiotics that you can give your pet:

There are more beneficial foods and supplements, so do your research and speak to your veterinarian before introducing anything new to your doggo’s diet.
