The answer is yes. Dogs fart. They pass gas.
It well-known that it is normal for gas to be produced and to accumulate within the gastrointestinal tracts. However, in some situations this production of gas is increased and can become excessive.
The most common cause of excessive flatulence is a change in diet or from the dog eating something new or spoiled. Most cases of chronic flatulence are caused by a diet that is poorly digested by the dog. These poorly digestible diets cause excessive fermentation in the colon and subsequent gas formation. Soybeans, peas, beans, milk products, high-fat diets and spicy foods are all commonly associated with flatulence in dogs.
Dogs are lactose intolerant and if they are fed milk or dairy products they will often experience flatulence.
Dogs that swallow air, especially those that eat quickly, are more likely to experience intestinal gas.
Overweight, obese dogs are at higher risk for developing chronic flatulence.
In any case, dog farts can be silent but deadly; they burst out of nowhere and can even be link with a sneeze or a bark.
In other words, dogs fart like humans.
