  • The 5 Best Dog Foods to Prevent Gas

    1. Royal Canin Dry Dog Food – Best Overall

    Royal Canin 517430

    Check Price on Chewy

    While we ran into some excellent products, Royal Canin Dry Dog Food steals the top spot for the win. It has exceptionally transparent ingredients known for aiding in digestive health without fillers and other harsh additives.

    This bag caters explicitly to adult dogs between 25-55 pounds, including the nutritional values to match. If your dog doesn’t meet the criteria, worry not! They have the same product for all weights and stages. This is just the one we picked to check out for ourselves.

    Royal Canin uses proper fiber and easily digestible proteins. Not to mention, they add antioxidants, prebiotics, probiotics, and DHA to touch every area from coat texture to gut health. We have all seen dogs use mealtime to show off their vacuum-eating skills. If your dog is one of them, this kibble is a perfect size to motivate your pet to chew their food.

    Royal Canin Dry Dog Food is a special scientifically designed recipe to target flatulence issues and support optimal health, so you don’t have to scrimp on value. The company even has a 100% satisfaction guarantee to back it up.

    All in all, we think that this is the best dog food to prevent gas.

    • Scientifically-backed recipe
    • Other recipes for all sizes and ages
    • Kibble size promotes chewing
    • Ingredients are well-balanced
    • Satisfaction guarantee
    • Not a grain-free selection
    • May not suit all diets

    2. Natural Balance Diet Dog Food – Best Value

    Natural Balance

    When it comes to our number two selection, value is essential. This Natural Balance 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.

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

    3. Nulo Grain-Free Dry Dog Food – Premium Choice

    Nulo Grain-Free

    The Nulo Grain-Free Dry Dog Food hits our number three slot because it’s a bit pricy but well worth it. It’s a nutrient-rich, grain-free, naturally flavored selection that supports healthy weight and proper absorption. This bag is for adult dogs, including those with allergies or sensitivities. They have similar recipes for puppies and seniors, tailored to meet their nutritional needs.

    This food uses a patented BC30 probiotic that is supposed to work very well to promote healthy digestion. On top of that, it is a low carb and high protein choice. That will help your dog’s overall health while making sure they aren’t gaining too many extra pounds.

    It is also ideal for dogs who suffer from medical conditions, as it gives them a diet that replenishes all vital vitamins and minerals, flora for gut health, and proteins for muscle solidity and coat texture. Plus, it is a dry food that adds a great crunch for cleaning teeth, decreasing plague, and reducing decay.

    Nulo is based in the USA, based in Texas. So, you can rest easy knowing this is a product you can trace for validity. If you are willing to foot the bill, this is our premium choice of the five.

    • Expensive

    4. Wellness Natural Dry Dog Food

    Wellness 89113

    Wellness 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.

    When it comes to the most important issue at hand—digestive health—it is guaranteed to aid in smooth digestion for more effortless bowel movements and fewer gases. It is full of much-needed probiotics and fiber.

    It is a deboned chicken and brown rice recipe with added whitefish. So, while it provides viable nutrients, it isn’t a good contender if your dog requires a grain-free menu. A perk for your large breed is that it includes glucosamine and chondroitin to strengthen joints since many big dogs are prone to hip dysplasia and joint issues.

    While it didn’t make the top three, it’s still a fabulous choice if you have a stout brute with flatulence problems.

    • Healthy digestion guarantee
    • Ingredients for joints
    • No artificial flavors or byproducts
    • Only for large and giant breeds
    • Not grain-free
    • Not for allergy or food sensitivity

    5. Diamond Naturals Dry Dog Food

    Diamond Naturals

    Diamond Naturals Dry Dog Food is our last pick. It has a lot of notable positives, but it may not be for every dog. This selection is geared toward more obesity-prone dogs. It helps to promote appropriate dietary supplementation while reducing the ingredients that make your pet pack on the pounds.

    Because of the fewer calories, you won’t want to feed this as a regular meal to a lean, muscular dog who is already physically fit. However, it does have an all-natural, filler-free, superfood-packed recipe that is sure to rouse your pooch’s appetite. It is not grain-free, so it won’t match all dietary requirements.

    Most significantly, it has live prebiotics and probiotics that thrive in your dog’s gastrointestinal tract. This guarantees proper digestion, gut health, and less gas.

    Additionally, it is full of protein from pasture-raised lamb. Family-owned Diamond Naturals is based in the USA and pretty interactive with their customer base. So, if you had any issues with your purchase, they take accountability where it is due.

    • Healthy digestion guarantee
    • Live prebiotics and probiotics
    • Customer-friendly company
    • Only for overweight or inactive dogs
    • Not grain-free
    • Not recommended for physical fit dogs
    • Not allergy or food sensitivity-friendly

    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.


    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.


    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.


    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.

    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.

    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.

    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.
