Fibers: The Unsung Heroes in Your Dog's Diet

Fibers: The Unsung Heroes in Your Dog's Diet

This is our series on the ingredients in Wild Earth’s Clean Protein dog food called ‘Ingredients With A Purpose’. We understand there are A LOT of options when it comes to what you feed your dog. We also understand you want to feed them the best food possible and labels can be confusing. The goal of this series is to give you insight into the role each ingredient plays in our food and the components that make a complete dog diet. We’ve broken the articles down into the components that make a healthy dog diet: ProteinFats & CarbohydratesFibersVitamins & Minerals.


Fibers are the unsung heroes in a complete dog diet. They do much more than help with digestion. The scientific community is learning more all the time, but healthy, soluble fibers can help with everything from digestion to reducing cholesterol, controlling blood sugar and boosting heart health. Our chief veterinary officer, Dr. Ernie Ward is on a mission to extol the virtues of healthy fibers for our pets.

“I’ve long been interested in the importance of dietary fiber in maintaining optimal health and extending longevity. In my opinion, many dog food diets don’t contain enough beneficial fibers, just like humans.” - Dr. Ernie Ward

What do Dogs use Fibers for?

Much more than you might realize! While fiber is most often associated with using the restroom - it has some incredible additional benefits. Certain fibers - known as beta glucans - found in fungal proteins like yeast and certain plants like oats have been studied to improve disease resistance, enhance vaccine efficacy and aid in immunity against infection. Much of the benefits of these beta glucans are due to the healthy bacteria they create in the gut - also known as the microbiome. While we’re currently learning the benefits in dogs, in humans a healthy gut is associated with stronger immunity, healthier skin, even mood and fighting autoimmune diseases.

There is still much to be learned about the benefits of fiber. At Wild Earth we feel we’ve only begun to scratch the surface with discovering the short and long term benefits of dietary fibers.  




Our favorite superfood. Yeast is a large contributor to the protein AND fiber content of our food. Containing those powerful beta glucans (and alpha mannans!), yeast is our not-so-secret ingredient. 


Another fungi containing healthy dietary fibers. 


Oats are extremely healthy grains that add protein, carbohydrates and fiber to our food. Like fungi (yeast and koji), oats contain beta glucans.

Sweet Potato

Sweet potato contains the soluble fiber pectin which reduces blood sugar spikes and helps with digestion. 


Similar to sweet potato, chickpeas are a source of both plant-based carbohydrates, protein and soluble fibers. 


While not as prevalent in our food as other ingredients on the list, pumpkin is well known to help a dog’s digestion. The good news is a dog doesn’t need much pumpkin to see the benefits.


Spinach is high in vitamins, fiber and minerals.

What Is Actually In Your Dog's Food?

WAIT! BEFORE YOU GO on about your day, ask yourself: Is the dog food you're feeding your best friend really the best food out there? At its core, there’s an unhealthy meat dependency in pet food. Most of the time, meat in your pet food means: Bad ingredients. Bad practices. And bad health. Learn more about clean protein dog food...
