What makes a dog fart?

By Jerry Welsh


Dogs have an unexplainable fondness for something smelly. Look how dogs love to roll in rotting animals, to wallow in stagnant water and even to eat obnoxious smelling spoiled food as well as their own poop. Should we be surprised at the dog's habit of detonating small bombs from the anus? Dogs, like their human friends fart and when the silent and deadly gasses are emitted, the room would be cleared instantly. Fart is not harmful to human health but let's face it, no one would love to have a pet that fills a room with horrific smell.

Gas, farting or flatulence are one and the same. Flatus that comes out from the anus is a mixture of methane, hydrogen sulfide, nitrogen, carbon dioxide and oxygen. The gas in the intestine is produced through the reaction of bacteria to the process of digesting the swallowed food. Another source of flatulence is the gas in the intestines from the blood as well as from the air swallowed by the dog when eating or drinking. The type of food eaten, the amount of air that is swallowed when the dog eats and the interaction of bacteria with the digestive process contributes to the production of gas.

Dog owners would know how fast dogs eat. Dogs normally do not chew their food. The habit of gulping food was inherited by modern day dogs from their ancestors that survived in the wild. Due to the scarcity of food, dogs have to gulp down the food - to eat fast to prevent predators and also other members of the pack from stealing the hunted prey. When dogs eat fast significant amount of air is swallowed as well.

The natural process of digesting food and the absorption of nutrients in the digestive tracts also produces gas. Production of gas is more enhanced in older dogs as the intestines' muscular tone is weakened as the dog matures. Some foods are noted to cause flatulence. Beans, cauliflower, dairy products are some of the foods that can make your dog fart more. Commercial dog food with more cereal fillers can cause flatulence.

Excessive farting can be reduced if the dog is given several meals of smaller ration instead of one big meal. To lessen the dog's flatulence, you can provide the pet with good quality food.
