Are my dog’s stinky farts a problem?

We’ve all experienced it. We’re enjoying our morning coffee or binging our favorite show and suddenly we're overcome by the stink. Your dog is innocently sleeping beside you but clears the room with each fart! But what causes these stinky farts, and should you be worried? In this article we’ll delve into the stinky world of farts!

Farts, gas or flatus—whatever you call it, all dogs experience it! The amount of gas varies among dogs and can even vary from day to day.

The most common causes of gas may include:

Swallowed air that’s gulped in when your dog eats too fast or during exercise.
Gas produced in their gastrointestinal tract after a meal.

When your dog eats, bacteria in their gastrointestinal tract kick into gear and begin to break down the food. Depending on the food, hydrogen sulfide gas is released as a by-product during the digestion process. The gas becomes trapped, and farting is the only way for it to get out.

A stinky fart from time to time is normal, but if excessive farting is new, other causes should be investigated, especially if your dog has diarrhea or you discover blood in their stool. Most cases of chronic gas are caused by a diet that’s poorly digested. This doesn’t necessarily mean the diet is of poor quality—though eating a low-quality diet or spoiled foods could make it worse—it just means that your pet is having a hard time digesting the food. Poorly digested foods may include soybeans, peas, beans, milk and dairy products (such as cheese) or high-fat or spicy foods. A sudden change in diet can also cause excessive gas.

On occasion, excessive gas can be caused by:

Inflammatory bowel disease (IBD) or irritable bowel syndrome (IBS)
Small intestinal bacterial overgrowth (SIBO)
Pancreatitis
Intestinal parasites

Speak to your veterinarian if your dog’s farts are silent but deadly. Your veterinarian may recommend pinpointing the cause by a process of elimination, and you might have to remove, and then slowly reintroduce, some ingredients from your pet’s diet.
