Is your dog suffering from gas? It should go away on its own after your pet vomits or has diarrhea. Otherwise, you will need to ask your vet for a pet-safe medication for flatulence. Your vet might prescribe Gas-X, a medication used for managing gas symptoms in humans that is also used for treating flatulence in dogs.

What is Gas-X?

This is a brand name for Simethicone, an anti-foaming agent which belongs in the anti-flatulent class of drugs. Antigas medications work by reducing the surface tension of gas bubbles in the stomach and intestines.

Contrary to common belief, it will not stop the gas from forming. Instead, Simethicone only speeds up the process of getting rid of the excess gas from your pet’s body. Gas-X works just after a few minutes since ingestion.

Gas-X can be bought over the counter and from online retailers. While it is easy to buy, don’t forget to practice caution when giving it to your pet. For proper dosages and administration, it will help to call your vet before giving it to your pet.

Is Gas-X Safe for Canine Use?

This drug is not absorbed from the GI tract so it is relatively safe for dogs. Still, it’s best to consult your vet before administering Gas-X. There are cases when Gas-X will not be applicable and it depends on the reason of flatulence.

Gas is not just caused by food or undue air consumption but it can also form in the gut when there is a bacterial infection. In cases like this, a vet may prescribe antibiotics if the issue did not settle on its own.

This drug comes in different strengths and forms. There’s the regular strength, extra-strength, and ultra-strength. Every tablet also contains 30 milligrams of calcium.

You can find it in chewable and soft gels format. Some vets also prescribe the Gas-X Infant Drops because it is easier to administer to pets compared to the tablets and gels.

If your pet is pregnant or currently nursing, ask your vet if it is okay to administer Gas-X. In humans, it is safe since it does not cause teratogenic effects. However, because dogs are different, it will not hurt to check on your veterinarian for confirmation.

What is the Gas-X Dosage for Dogs?

If you are wondering how much Gas-X is safe for dogs, just give around 1 to 2 milligrams per pound of body weight. It should be given every 8 hours. It is recommended to give it after a meal or before bedtime.

If you own a small breed dog weighing around 8lbs, you may give him 8-16 mg of Gas-X. Since a regular strength tablet of Gas-X contains 80 milligrams of Simethicone, you may give your pet a quarter of a tablet. One tablet is safe for a large dog weighing 40 lbs and over.

What Are the Risks of Administering Gas-X to Dogs?

There is a very minimal risk in giving Gas-X to dogs. The only problem you will encounter is when your pet ingested more than the recommended amount. Simethicone can cause a gastrointestinal disturbance in unreasonable amounts.

Although rare, dogs can possibly suffer from intense allergic reactions after consuming a lot of Gas-X. This is a type of emergency situation so the dog has to be taken to the vet for diagnosis and treatment.

What To Do If Your Dog Ate Simethicone?

The dog will likely experience diarrhea after ingesting Simethicone. It may cause a dog to have loose stools. This can be treated by fasting 12 hours to allow the stomach to rest. Make sure to keep your pet well-hydrated during the fasting.

Offer small, bland meals frequently thereafter. Your best options are boiled hamburger and chicken with rice. A trip to the vet will only be required if your pet does not want to eat anything or if diarrhea lasted for more than a day.

What Causes Flatulence in Dogs?

The stomach naturally has gas-producing bacteria. It becomes distended if the gas is not able to escape. The build-up of gas can make the dog uncomfortable. You will know your dog has gas if he produces a strangely foul odor and if there is a rumbling sound from his gut.

A sudden change in an animal’s diet can result in extreme gas. Some foods can cause your dog to fart or suffer from bloating. Beans and lentils are common examples of gas-producing foods. Vegetables and fruits cause intestinal gas due to their natural sugars: the fructose and the lactose.

Fructose-containing fruits include bananas, mandarins, grapefruits, blackberries, raspberries, and figs. There are a lot more on the list but these are the fruits commonly served to dogs. It’s important to serve fruits in moderation.

Meanwhile, foods containing lactose include milk and other dairy products. While there are dogs that can digest lactose without a problem, some go through intestinal distress after consuming milk and dairy. If your pet had a history of food allergy, better avoid dairy at all costs.

Gas can also be a result of inflammatory bowel disease (IBD). It can happen to any dog breed but terriers, German Shepherds, and Shar-Peis are more prone to it than the others. This condition is a result of having an excessive amount of inflammatory cells in the body.

The Bottom Line

Gas-X or Simethicone has a high margin of safety for dogs. However, it is still necessary to consult a veterinarian especially if your dog often experiences gas. Flatulence is normal in dogs but it is supposed to occur sporadically. If it happens often, it might be an indication of a bigger health problem which requires veterinary attention. Gas can be an indication of IBD and other problems of the digestive tract.
