Why Does My Dog Fart So Much?

why is my dog farting so much

If your dog is farting a lot more than usual, it could be from one of three things:

  1. Diet
  2. Underlying disease/illness
  3. Eating habits

Let’s dive into each for a comprehensive understanding of why your pup is farting so much.

1. Diet and Your Dog’s Gas

We once received a funny email from one of our customers, it was titled “by the way…..good intel for your farty dog clients…” and it said:

“I have 2 Frenchies. They used to be terrible farters, even on prescription, supposedly high-quality food. They’ve been on JFFD for about 2 months now and are FART FREE!! YAY! We can have company over again, LOL! Just thought that might help you if you get that question.”

We do get this question a lot – why does my dog fart so much? or, why does my dog poop so much? The answer is usually a similar one for both.

Excessive gas and increased fecal output is usually a sign of indigestion of some sort. Thus, flatulence and excessive pooping may be signs that your dog is having trouble digesting his/her dog food. Although there are also some diseases that could cause these signs, (and those must be considered), many times, simply upgrading the low-quality food to a more bioavailable, higher-quality diet will resolve the gas and fecal volume problem.

Conversely, some of our clients also become concerned about the reduced amount of feces produced after switching to our diets. People say, “My dog used to poop three times a day – a lot, and now he only poops a small amount, once – where is it all going?”

We have to remind clients that dog poo is essentially “waste”. It is the indigestible portion of the food. Thus many times: the least poop, the better nutrition (provided the dog isn’t losing weight).

Dr. Julie Stegemen, a board-certified veterinarian in internal medicine, explains this dog poo phenomenon for pet parents in the video below.

2. Disease or illness

According to Texas A&M University’s School of Veterinary Medicine & Biomedical Sciences, your dog’s excessive flatulence could be a sign of an underlying health problem.

Possible health issues that are common causes of dog gassiness include:

  • Irritable bowel syndrome
  • Intestinal parasites
  • Exocrine pancreatic insufficiency
  • Pancreatitis
  • Inflammatory bowel disease
  • Bloat

If the chronic flatulence is not from your dog’s diet, make an appointment with your veterinarian to determine the underlying cause.

Gastrointestinal upset

Research shows that when the dog’s digestive system is upset, it can benefit from probiotic supplements. “Probiotics normalize the conditions in the intestines by changing the local acidity of the digestive tract and releasing short-chain fatty acids,” reads an article in Cornell University College of Veterinary Medicine’s DogWatch newsletter. “This gives dogs a leg up if they end up ingesting harmful bacteria such as Salmonella.”

The “good bacteria” provided by probiotics can improve and maintain a dog’s digestive health, and in turn, reduce large amounts of farting.

Food intolerance or allergies

Your dog’s flatulence could be from food sensitivity. If your dog’s gas is accompanied by diarrhea, inflamed skin, itchiness, or an ear infection, food allergies could be the culprit.

Take your pet to the DVM to determine the exact cause. It could be anything from dairy products/lactose or Brussels sprouts to poultry or soybeans, so they will likely tell you to do an elimination diet. Then you can figure out how to alter their dog food to a new food that is more tummy-friendly. Avoid giving table scraps of human food that they may have an intolerance to.

3. Eating habits

If you can rule out disease and diet as the causes of your dog’s toots, their eating habits could be the culprit.

Does your dog eat kibble so fast that mealtimes last only a few seconds? Speedy eaters aren’t just inhaling their pet food, but wolfing down lots of swallowed air. A lot of air in your dog’s body causes severe digestive issues that can lead to bloat (where the stomach twists), which is deadly if not treated quickly.

If your furry friend eats with the speed of Usain Bolt, it’s time to look into getting a slow feeder to prevent serious consequences.

Helping Your Gassy Dog

Some dog breeds, specifically brachycephalic breeds like pugs and French bulldogs, seem more prone to smelly gas than others. When excessive farting isn’t a result of an underlying illness, however, it usually ultimately boils down to diet.

Take things slow when transitioning your dog to a new food. They could get an upset stomach due to such a sudden change.

To make the transition, mix your dog’s current food with their new food, gradually decreasing the amount of old food and increasing the amount of new food over a period of 7 days.

Again, talk to your veterinarian to narrow down the exact cause of your dog’s excessive flatulence.
