1. Taste of the Wild – Editor’s Choice

View Latest Price

Taste of the Wild is a popular brand with a great reputation. Made in the USA, Taste of the Wild is a family-owned business with a Missouri headquarters. They source all their ingredients from sustainable providers that they trust. The basic premise of their food is to try to replicate a wild dog’s diet – high in protein and easy to digest, without grains and fillers.

There are a range of different flavors and varieties, all packed with premium animal protein and highly digestible. The “High Prairie” formula uses real buffalo as the main ingredient, supplemented by other “meal” proteins. They aim to replicate a perfect profile of amino acids to support the development of lean muscle.

For carbohydrates, they choose sources that are easy to digest, such as sweet potato and dried chicory root, and avoid grain, corn and wheat.

To help the overall health and digestion of your dog, fruits and vegetables are added to increase the range of vitamins and minerals and natural antioxidants in the food. Probiotics are added after cooking, so they are fully active and thrive to aid digestion. 

Omega fatty acids from sources such as salmon oil, ocean fish meal or plant sources maintain your pet’s overall health from nose to tail. Chelated minerals attach themselves to protein to help increase absorption in the gut. There are no artificial colors, flavorings or preservatives.

All in all, they aim for a recipe that avoids potential allergy triggers and instead is nutrient rich and easy to digest.

Best Dog Foods to Prevent Gas Buyer’s Guide 2020

Why do Dogs get gas?

Flatulence is common and quite normal among dogs just as it is in humans. It’s just a byproduct of the digestive process. Some dogs are notoriously more gassy than others. The most gassy breeds are: Mastiffs, Boxers, Pugs, Beagles, Rottweilers, Pitbulls, Golden Retrievers, Bulldogs and Boston Terriers.

It’s also possible that large dogs experience digestive issues more than small.

However, if you notice an increase in the amount of gas, or it seems to be much more frequent than other dogs, it might not be quite normal. 

There are a few different reasons why a dog might get gas:

  • Diet is the leading cause of gas in dogs. Some foods that are high in fiber can be difficult for your dog to digest and lead to a buildup of gas, but high meat content food can also produce some terribly odorous flatulence. 
  • Allergies or Sensitivities – an often-overlooked cause of gas.
  • Sudden change of diet – if you are changing what your dog eats, it should be a gradual change, mixing in just a little of your new food with their usual food and gradually transitioning with less and less of the old food and increasing amounts of the new food.
  • Eating something that has spoiled.
  • High-fat or spicy foods
  • Eating too fast and swallowing air (aerophagia).
  • Being overweight or obese.
  • Inflammatory bowel disease (IBD)
  • Too many bacteria building up in the small intestine
  • Parasites in the intestines.

If your dog is especially gassy, it would be a good idea to consult your veterinarian to see if there’s anything going on under the surface.

To reduce your dog’s flatulence, you’ll need to work out which of the above triggers is responsible.

Dog Food for Flatulence

Your dog’s food should be highly digestible with few ingredients and preferably whole-food and not too much fiber.

There isn’t a single ingredient in dog food which is responsible for flatulence. In fact, your dog could be allergic or sensitive to just about any ingredient in dog food. The most common culprits are food additives, common proteins, low-quality grains and dairy products.

Look for natural ingredients. The dog’s body is designed to digest food from its whole form, not highly processed and with many additives and preservatives. The closest you can get to a whole-food natural diet, the better.

Dog food should have protein as their main ingredient, but many animal foods use mycoproteins and plant-based proteins such as corn-gluten or soybean meal. They are largely indigestible for dogs so should be avoided. The best quality foods have named protein such as beef, chicken or salmon as their main ingredient rather than unnamed “animal” or “poultry”, meal or byproducts.

Red meat can make flatulence worse, so white meat or fish as the main protein ingredient is best. 

Limit the numbers of high-fiber carbohydrates and grains such as corn and wheat in your dog’s diet. They have trouble digesting these. Ground rice or sweet potatoes are better options.

Look for foods which are rich in omega fatty acids. They are great for your dog’s health, benefiting their skin, fur, joints and digestion. At the same time, avoid artificial additives such as preservatives, dyes, flavorings etc, which can often trigger food allergies.

Look for AAFCO approval. The Association of American Feed Control Officials oversees animal food labelling. It has to reach certain standards for approval.

Other ways to prevent gas in dogs:

Here are some top tips to consider to reduce flatulence in feeding as well as changing their food:

  • Supplements including zinc acetate or Yucca schidigera may be helpful.
  • Feed smaller meals more frequently.
  • Use a slow-feed bowl to make your dog take his time and gulp down less air while eating.
  • Avoid feeding table-scraps.

You could also try some of the tips in this article.

If excessive flatulence continues after you have tried improving diet and some of the other tips suggested here, it may be time to see your vet. They will be able to identify any medical issue that could cause the excess gas.

Final Thought on Choosing the Best Dog Food to Prevent Gas

In the end, your choice of which dog food to get will depend very much on your dog. We’ve given you information about some of the best ones here, but every dog is an individual and the likely cause of your dog’s excess gas could be any number of potential ingredients so you may need to try a few to find the one that works best for your dog.

Remember to change to a new food gradually and to give it a few weeks to see if there’s any improvement in your dog’s overall health and flatulence. 

There are a few dog food formulas that focus on limiting the number of ingredients, such as Nature’s Variety Instinct Limited Ingredient DietNatural Balance LID FormulaZignature Limited Ingredient Recipe or Wellness Simple LID Grain-Free.

With a senior or a puppy, we recommend Canidae Grain Free PURE Senior Recipe or Blue Buffalo for puppies.

For a Scientific approach with a huge range of varieties you might consider Hill’s Science Diet Dry Dog Food for Sensitive Stomach and Skin or Purina One Smartblend Natural Sensitive Systems and for a company with one of the highest standards of food labelling and safety in the business, you might consider Holistic Select Natural Dry Dog Food.

Our personal favorite, and Editor’s Choice today, is the Taste of the Wild food. You don’t get the kind of reputation Taste of the Wild has without doing a lot right. We love their focus on a small number of very high-quality ingredients. Read our Taste of the Wild Review here.
