Dog Food Fiber


The following items represent some of The Dog Food Advisor’s most frequently asked questions about dog food fiber.

How is dietary fiber beneficial to a dog’s health?

Dietary fiber found in dog food can improve colon health, aid in weight management and help stabilize blood sugar levels in diabetic dogs. It can even help control both diarrhea and constipation.

What causes my dog to generate such a large volume of stool?

To a notable degree, stool size and form can be directly related to the fiber content of a dog food.

What ingredients contain the most fiber?

Because fiber is only found in the wall of a cell (and since animal cells don’t have cell walls) fiber can only come from vegetables and grains. Never from meat.

That’s why one should expect plant-based dog foods to generate more stool volume than meat-based products.

How can dog food fiber help a diabetic dog?

Fiber can help a diabetic dog maintain stable blood sugar levels.

Although higher dietary fiber was initially believed to be beneficial, recent studies have suggested there may be no real advantage to high fiber diets compared to the more moderate type associated with many commercial foods.1

How does dietary fiber help control inflamed anal glands?

Fiber can absorb water directly into the colon. The enlarged stools fiber can produce is able to place added pressure on a dog’s anal sacs during defecation.

And that pressure can help induce the drainage of swollen anal glands.

    Exocrine Pancreatic Sufficiency. (EPI) I have a corgi with EPI. He requires a high protein low fibre diet. Apparently, high fibre foods diminish the effects of his medication Viokase. (Digestive Enzyme tablet)

    I found he reacts bad with Acana or Orijen (5% fibre) but does very well on Taste Of The Wild ) 3%fibre.

    Let’s get a bit gross! For dogs with EPI, telltale signs his fibre is to high, is when his poop gets soft, extra smelly, and slimy. The outer core of his poop looks like it’s wrapped in something. If his stool somehow resembles this, his fibre is to high, and he is not producing enough digestive enzymes through his medication. Hope this helps someone out there!

    I am currently feeding my dogs Fromm Family Foods, which has 3.9%fiber content. For my two JRT’s the food has been perfect. For my lab and newly adopted Husky X, they have been pooping like crazy! My Husky X is still house-training too (which is part of why I notice so much!) I only recently thought about the volume my lab poops after noticing our new Husky seemed to be pooping an exorbitant amount. I have purchased Pinnacle Peak Protein Formula for its low fiber content (2%). I hope it helps.

    Try this list of foods that are low fiber & low fat intended for dogs with EPI:

    I’m not suggesting that each food will be appropriate for your dog’s needs. You’ll need to research each food to ensure that the fat & fiber levels are appropriate for your dog.

    Be careful with that Natural Balance Fat Dogs. Natural Balance is now owned by Del Monte who gets most of it’s ingredients for their dog products from China. Many people are quitting Natural Balance because of this.

    Blue Buffalo Wilderness “healthy weight” has 9% fiber, Wellness core reduced fat formula has 8,5%, the new Natural Balance “fat dogs” has 10,5%, i am trying this one out right now since my dog has anal gland issues for years.

  • Hound Dog Mom

    Acana Light & Fit and Wellness Core Reduced Fat are both rated 5 stars and have a little more fiber than Nutrisca.

  • Sammy’s mom

    Nutrisca is the highest, just went through all the labels at the pets store (higher end foods only) & gets a 5 star rating here
