Dog Farts 

All dogs have gassy moments. However, it may be cause for concern when they have excessive gas or a dramatic change in the amount of gas they experience. This is most often a result of eating bad eating habits, a poor diet, or just eating things they shouldn’t!

That said, some dogs are naturally gassier than others. For example, dogs with flat faces like Pugs tend to pass more gas because they take in more air when they eat. Elderly dogs also tend to flatulate more as their digestive systems are slowing down. Gas collects in the stomach in two ways; swallowing air while eating and drinking and during digestion. Both can result in flatulence. However, if a dog’s diet is not compatible with its digestive system, it can cause excessive flatulence. 

To prevent excessive gas and keep your dog’s gastrointestinal system healthy, they should eat only high-quality kibble/dog food, natural sources of protein, and dog-safe fruits and vegetables. Tasty treats are to be enjoyed in moderation, and dogs should only drink water. Probiotic supplements are available for dogs with sensitive stomachs that need extra digestive help. Owners of gassy dogs with flatulence should also avoid commercial dog foods that contain filler ingredients such as grains and artificial additives. 

Dog farts are very similar to human farts – canine flatulence is caused by a buildup of gas in the intestinal tract and colon.

Common Causes of Gas in Dogs

These are the most common dietary causes of excessive gas in dogs. 

Human Food

Feeding dogs human food is the most common cause of excessive canine flatulence. Although humans and dogs can eat a lot of the same things, there are certain foods that are really only for human consumption. Specifically, peas, beans, dairy products, high-fat and spicy foods. Although they aren’t necessarily toxic to dogs, aren’t well-suited to them either.

Poor Quality Food

Dogs often experience excessive gas from eating dog foods that are low in quality. Although it seems counter-intuitive, a lot of commercial dog foods use so-called “filler” ingredients such as grains that are hard for them to digest. This is because they are much cheaper to manufacture than nutritious ingredients.

Many dogs who eat these foods won’t experience specific health problems due to them. But they will generally not be as healthy overall as they could be if they ate a better diet. For dogs with sensitive stomachs, however, these foods can be damaging and make them unwell and unhappy.

Food Intolerance

Dogs can also experience food intolerances that can cause gas. Common food allergies include gluten and certain proteins. If your dog is experiencing other food intolerance symptoms such as an upset stomach and dull coat, talk to your vet about doing a “food trial” to work out the problem. 

Eating Too Fast

Another possible cause of gas is eating too quickly. Some dogs, especially younger ones, eat far too quickly because they have not yet outgrown the puppyhood habit, or they are just greedy! Some dogs may also eat their food too quickly because they have trust issues. 

Not only is this a choking hazard, but it can cause uncomfortable and painful indigestion, flatulence, and in extreme cases, a deadly condition called bloat.

Owners of dogs that eat too quickly should invest in a slow-feeding bowl. Textured slow feeders cause pets to slow down during mealtimes, encouraging better eating habits and healthier digestion. They’re a lot of fun for dogs, too.

Eating Non-Foods

Another cause of excessive gas in dogs is eating things that aren’t food. Culprits are usually young puppies who are overly curious (and a bit naughty). Puppies will often eat things like dirt and sand that cause flatulence and upset stomachs. 

This is likely temporary and boredom-related, but if your dog does not grow out of it or an older dog starts to do it, you should take them to see a vet as it could be a sign of a nutritional imbalance. 

What To Look For In Dog Food

Food is one of the most important factors in a dog’s health that is within our control as owners. When shopping for new food for your dog, it is essential to take these factors into consideration. 

  • Age appriopriate food
  • Breed/size-appropriate food
  • Natural ingredients 
  • No filler ingredients
  • 100% complete nutrition
  • Tasty to eat 
  • Positive reviews

Some other factors owners may want to consider include:

  • Cost
  • Bag size
  • Ethically sourced ingredients
  • Manufacturing location
sensitive stomach dogs
Some breeds have sensitive stomachs and would get diarrhea or fart a lot if fed the wrong type of food.

Food For Dogs With Gas – FAQ

Why does my dog suddenly have bad gas?

Dogs most commonly develop excessive gas from eating a poor quality diet or eating too quickly. They can also experience food intolerances that cause flatulence. Puppies also often get upset stomachs and gas from eating things they shouldn’t like mud and grass.

What foods make dogs fart?

Foods such as peas, beans, dairy products, high-fat and spicy foods that are meant for human consumption are not great for dogs. Although they aren’t necessarily toxic to dogs, they aren’t well-suited to them either and can cause excess flatulence and stomach upsets. So, it’s best to avoid them!

Dogs also experience excessive gas from eating commercial dog foods that contain low-quality “filler” ingredients such as grains that are hard to digest.

Should I be worried if my dog farts a lot?

Flatulence in dogs is completely normal. Some dogs also fart more than others. For example, dogs with flat faces tend to pass gas more than others because they take in more air when they eat. Elderly dogs also tend to flatulate more as their digestive system slows down. 

However, if you think your dog’s gas is excessive or you notice a significant change in the frequency of their flatulence, it’s best to contact your vet to be on the safe side.

Do dogs fart when stressed?

Stress can cause stomach upsets and more gas than usual, as it accelerates bodily functions, but if you can’t identify a reason for your dog to be stressed, don’t panic. It’s far more likely to be diet-related. 

However, if you think your dog is stressed, try to eliminate the cause or associate it with something positive if it’s fear-related. Adequate exercise, a firm daily routine, lots of fun, love, and some relaxing cuddles will also help. There are also commercial herbal supplements and plug-in products out there for alleviating anxiety in dogs.

Those are our 12 best foods for gassy dogs! Remember, if your dog is experiencing excessive gas, speak to your vet before making any drastic changes to their diet.
