Top 10 Best Dog Food to Prevent Gas (flatulence)

Top 10 Best Dog Food to Prevent Gas

Picture this. You are finally lying down after a long day. Suddenly, noxious gases fill the room again. Having your dog overpower your air freshener probably isn’t the way you want to spend your time inside. To be honest, they probably aren’t having a good time, either!

You may dismiss your dog’s never-ending flatulence, thinking that is normal. On the contrary, it is almost always a dietary concern. Something about your food choice doesn’t agree with their digestive tracts. So, we have compiled a well-tested top 5 dog food reviews to ward off those unpleasant scents and to get your dog back to being healthily gas-free.

The 10 Best Dog Foods to Prevent Gas

Taste of the Wild

Packed with premium animal protein, Taste of the Wild High Prairie Grain-Free Dog Food is one of the best options to help gassy dogs. This animal-based protein is extracted from venison, bison, boar, lamb, salmon, and wildfowl. With exceptional protein to fat ratio, this dog food has an excellent nutrient profile and is rich in essential omega acids. Highly Recommended!

Natural Balance Diet Dog Food – Best Value

Natural Balance

When it comes to our number two selection, value is essential. This Natural Balance 43135 Limited Ingredients Diet Dog food is the best dog food to prevent gas for the money. It is a specialized recipe that suits puppies, adults, seniors, and food-sensitive dogs.

This Natural Balance product is a wet dog food that is high in fiber. This is terrific because most dogs don’t get enough hydration in their diets. It’s a perfect way to add extra water content, which also helps with intestinal breakdown.

It also has a downfall, keeping it out of the number one spot. Not all dogs are ideal candidates for wet foods. If they suffer from canine plague or dental issues, wet food can sometimes make them worse. So, caution if your dog is prone to build-up.

To counteract that, it is a grain-free food, so this can be a great choice if our number one didn’t work due to dietary specifications. The fish content in the can have a strong aroma, but if you don’t mind, your dog will probably gobble it up. So, you can save money while appealing to their taste buds.

  • Could cause dental issues
  • Odor
  • Few ingredients
  • Grain-free
  • High in fiber
  • For all stages of life

Wellness 89113 Natural Dry Dog Food

Wellness 89113 Natural Dry Dog Food is another fantastic choice, but the formula is for adult large to giant breed dogs. So, while it is in our top five, it is only appropriate for bigger dogs. It contains no wheat, artificial flavors, or byproducts, so you can give your big guy a wholesome diet.

Buyer’s Guide: How to Choose the Best Dog Foods to Prevent Gas

There are quite a few things that go into making sure you are providing the right diet for your dog which includes choosing the best dog foods to prevent gas. While you want to get the gas issue under wraps, you will also want to choose the right food that caters to every aspect of the health of your pet.

Age Requirements

First and foremost, you will want food that supports the age range of your dog. Canines, like any creature, need different levels of nutrients to match the varying stages of their lives. Dog food companies will have the age range specified both on the bag and in the description.


  • Once they reach adulthood, their diets will need adjusting. Because puppy chow has so many power-packed ingredients to support growth, it isn’t suitable for adults. You may think that too much of an element couldn’t possibly be a bad thing. However, because of the abundance of calories and fats, it can cause obesity.
  • Adult dogs need maintenance diets that keep nutrient levels even, providing adequate protein, carbs, and vitamins and minerals. Adults will also require different types of food based on their individual needs. Some dogs need a diet with lower calorie content and higher protein. Some require grain-free or all-natural for certain medical conditions. The exact combination will depend on the individual.


Dogs continue to develop until they reach 24 months of age, on average. While they are growing, they need an adequate supply of different ingredients to promote optimal health. They will need higher levels of protein to support their growing muscles and bones. They also need plenty of DHA, calories, and omega-3 fatty acids.


  • Like puppies, seniors need a specific diet to help as they age. They need food that supports bone health, weight management, and longevity. They will also need a fiber-rich diet to help aid in digestion since their GI tracts become slower with age.
  • On top of typical weakening in older pets, there are quite a few health issues that could come about as well. Older dogs are prone to degenerative conditions like eye disorders, diabetes, cancers, heart conditions, and joint problems.

Diet Specifications

More often than not, the reason your dog seems overly gaseous is due to a digestion problem concerning a food sensitivity. It can seem like a tedious process to try to sift through ingredient labels, axing the ones you and your vet feel may be causing the issue. It can lead to a lot of trial and error, but eventually, you will get there.

Novel Protein Source

A novel protein source is a protein that the dog has had no exposure to in the past. That eliminates the chance of a trigger response in the dog, leading to improvement. They should be purely hypoallergenic. These proteins are often derivatives of venison, duck, or another exotic meat that is uncommon in mainstream foods.

Food Trials

  • When it comes to a food allergy or sensitivity, it is unfortunate that testing may not be as simple as a skin allergy. Many times, your vet will recommend food trial testing to see where the issue stems.
  • Frequently, dogs have reactions in direct relation to the type of proteins used in the food. Meats like beef and chicken are often to blame. Other issues can be against their favor as well, such as wheat, eggs, or dairy. Cutting each one can take time, and it does require patience to see results.

Hydrolyzed Diets

They produce this type of food by using water to chemically breakdown existing proteins into microscopic molecules. Once they reduce the proteins so drastically, they are supposed to break up so well that the immune system no longer reacts. Hydrolyzed diets are used for inflammatory bowel disease and food allergies alike.


  • As information swirls around about the issues dogs face with their diets, more options become available to owners. Of course, you will want to address your dog’s health concerns while saving as much money as you can. Dog foods can get pricy, but some brands offer very similar recipes for more affordable prices.
  • Work with your vet to eliminate allergens or digestion disorders. Once you pinpoint the trigger, find a selection that is both in your price range and in alignment with their needs.

Final Thoughts

Our top selection of Royal Canin Dry Dog Food is the most versatile and highly regarded on the list. It provides an incredibly balanced diet and supplies nourishment for easy digestion. While not grain-free, it’s packed with premium ingredients that are scientifically chosen. Royal Canin also provides a satisfaction guarantee.

Again, wet food is great for hydration, which in turn is good for digestion. It’s a grain-free selection, which is best if your pet suffers from food allergies or sensitivities. If you want a high quality, low priced food, this is the one for you.

If money is no object, our premium choice—Nulo Grain-Free Dry Dog Food—is another impeccable choice. It’s grain-free, low carb, high protein, and only uses select ingredients. You can rest easy knowing you aren’t loading your dog full of unnecessary additives. It is also made in the USA.
