Like most animals, dogs have gas, usually caused by a component of their diet. Diet changes can usually help clear up the problem, unless it's caused by parasites or other illness.
Feed Premium Food
The more pure protein that your dog receives, the less gas he will have. Gas is often caused by difficulty digesting food, and dogs have difficulty digesting foods such as grains and meat byproducts, which are present in many commercial foods. Dogs can't digest corn or wheat, the main ingredients in several commercial brands.
Thus, look for food that boasts mostly protein, eggs, vegetables and grain such as barley. Avoid foods that advertise a general protein, such as "meat" or that use meat byproducts, which can include feathers and other nondigestible items.
Try Different Protein
Sometimes gas appears because of food sensitivity, which can be caused by eating foods that don't sit right with your dog. You may see other symptoms, such as diarrhea, excessive itching or ear infections, but if the intolerance is mild, gas may be the only symptom.
Protein is the most likely culprit once you have eliminated byproducts and grains from your dog's diet, so try switching to a different protein source. Most foods are based in one protein, such as chicken, turkey, beef or lamb. If your dog struggles with one brand or one protein, try switching to another.
If your dog is already fed premium kibble, try a lower protein kibble with a fish or turkey base. These are often advertised as senior or diet foods. Some dogs get more protein than they need, causing gas. Reducing the protein level without sacrificing quality may improve your dog's digestive system.
Reduce Treats
Often, kibble isn't the only source of nutrients for your dog. Owners also add treats and even table scraps as extra rewards for their dogs. However, if you have identified one source of protein or one ingredient as a problem, you need to remove that from the diet completely.
Choose premium, high-protein treats, just as you choose premium food, and remember the rule about digestible foods. Your dog may not be able to digest leftover lasagna as well as he can digest boiled turkey. Be aware of all the foods you give your dog when trying to reduce gas.
Certain bones like raw hides can also cause excess gas. Many dogs have trouble with these, so try removing them for a week and see if you notice an improvement.
Feed More Frequently
Just like people, some dogs don't do well consuming one or two large meals a day. Try breaking the meals into three or four smaller meals while still feeding the same amount. This will allow your dog's digestive system more time to process each meal.
Additional Supplements
Finally, there are a few supplements that may help your dog's digestive system function more efficiently. Peppermint and Nux Vomica are natural methods that can help clear the pipes. Peppermint leaves can be torn up and given with food while Nux Vomica should be given separately.
Adding enzymes can help your dog's body break down food, and probiotics often promote a good digestive tract by adding healthy bacteria. Adding a little of this to your dog's diet can make them more comfortable and easier to tolerate!
