Why Do Dogs Fart? How Can I Prevent It?

In this article we tackle the embarrassing (or funny, depending on who you ask) topic of farting dogs.

Do Dogs Fart?

The short answer is yes, they do. If you have ever heard somebody blame the dog for farting, they might be telling the truth. Just like ours, a dog’s fart can be loud and intrusive or silent but deadly. In fact, depending on a number of factors, some dogs can fart rather a lot!

Why Do Dogs Fart?

“What causes farting in dogs?” I hear you ask. A fart is the body’s way of expelling air and gases that become trapped in the digestive tract. Without farting, your dog would become bloated and uncomfortable – just like you would.

Although farting is considered to be a natural part of the digestive system, there are a number of things than can induce excessive farting.

Swallowing Air

Is your dog always snoring? If so, he could also be swallowing air at the same time. Unfortunately, some breeds with short noses and a and flat and wide skull or more prone to this as they are mouth breathers. These dogs are known as brachycephalic and include breeds such as Pugs and Bull Dogs.

If genetics is the cause, there is not much you can do about this. However, overweight dogs are more prone to suffer from swallowing air regardless of the breed. Keeping your dog at the correct weight will help eliminate or reduce this problem. So, if Fido is a little on the large side, it’s time for him to go on a diet!

Eating too quickly

Some dogs get a little too excited a meal times and wolf down their food like they haven’t had any for days. Eating this quickly will also cause your dog to swallow air.

If your dog is guilty of this, there are a number of things you can do to stop it. Training your dog to be patient and eat the food slowly is the best way. However, if you’re struggling with this, you could try to obstacles in the way to force your dog to slow down. An example would be to place an upturned bowl inside their food bowl. This will mean your dog needs to eat around the bowl and will take smaller mouth fulls and a little more time. There are also dog bowls you can buy that make your dog work for their food.


Have you ever noticed what happens when you eat foods such as Brussels sprouts, beans or cabbage? That’s right, farting! That’s because these foods are packed full of carbohydrates. Feeding these foods to your dog’s digestive system will result in the same response as yours – more farting. If you’re feeding your dog scraps, try to be mindful about what’s on the plate.

Low quality dog food could also be to blame. That’s because these foods contain fillers such as wheat, corn and soy. Try to look at the label before you buy dog food. Switch brands if necessary. Any diet changes should be made gradually. Sudden changes can cause stomach upset and possibly make the farting worse.


Excessive farting could be a sign of a more serious problem such as parasites. Giving your dog worming tablets on a regular basis should help to prevent this. However, if you suspect parasites and the worming tablets do not work, you should consult a qualified veterinarian.

What’s With the Bad Smell?

Ultimately, sulfur is the cause of the bad smell in farts. The more sulfur in your dog’s diet, the worse the smell is going to be. Unfortunately, a lot of dog food is packed with the nauseous gas. To reduce the smell, try looking for a dog food that contains less sulfur.

Is Farting a Problem?

A normal amount of farting is nothing to be concerned about. However, if you dog’s flatulence is persistent it could be a sign of a more serious problem – especially if you think you have already ruled out parasites with regular worming.

Excessive farting could be caused by something that needs treating at the vet, such as bowel disease. So, if your dog is farting more than normal, it could be time to take a trip to the doggie doctor.

How Do I Stop My Dog Farting So Much?

There are a number of ways to reduce the amount of farting your dog is doing, namely by addressing the causes listed above.


Firstly, you should address your dog’s diet. As mentioned, buying quality food that does not contain wheat, soy or corn could be a first step. Reducing the amount of scraps your dog gets from your plate is another good bet. If you still want to treat your dog to scraps, at the very least you should check your plate to make sure it does not contain food such as cabbage and beans.


Adding probiotic supplements to your dog’s food will help him digest his food more easily without the need for all that gas. You could also try herbs such as peppermint or fennel. These will help to relax the stomach muscles.

Weight control

If your dog is overweight, he may be swallowing too much air. Putting your dog on a diet will not only help with the farting but will also boost your dog’s health in a number of other ways.

Exercise following a meal will also aid the digestive system in its work. This should result in less farting. At the very least, it would help to work the air out of your dog’s digestive system and those farts will be released outside rather than on your sofa.


Blaming the farts on the dog is a common tactic in most households. If Fido really is to blame, however, you can follow the steps above to get back to a pleasant smelling home.
