The Benefits of High-Fiber Dog Foods

Fiber in dog food

Fiber provides many of the same benefits for dogs that it does for their owners. Some of the most noteworthy include:

Improved Digestive Function

Fiber demonstrates an amazing ability to regulate digestive function. It can help draw water into the intestine when necessary to combat constipation, and it can help absorb water from within the intestine, to help combat diarrhea. It also provides additional bulk to your dog’s stools, which can help further ensure smooth intestinal function.

Yup, fiber is pretty awesome for your dog! If your dog’s stool has any irregularities, chances are fiber can help.

Beware though: Too much fiber in your dog’s food will cause her to poop way too much, and it can also cause horrifyingly foul-smelling gas. It is always important to increase the fiber content of your dog’s food slowly.

Improved Blood Sugar Levels

Fiber helps to keep your dog’s blood sugar levels within a more consistent range, which can help prevent obesity and canine diabetes. In fact, is often packed with fiber. It has similar effects in humans, who are also advised to consume plenty of fiber to keep blood sugar levels stable.

Satiation from Fewer Calories

Fiber takes up a bunch of space in your dog’s stomach, and because it isn’t digested by the body, this is essentially a calorie-free way of helping your dog feel full and satisfied.

Obviously, your dog still needs plenty of protein, fat and digestible carbohydrates, but by mixing in a few high-fiber ingredients, your dog will feel full, while ingesting fewer calories.

This is why fiber is often a major ingredient for dog foods designed to help your dog lose weight. For dogs who are struggling with obesity, it may be smart to replace your dog’s standard treats with high-fiber dog treats for a while too!

What Is Fiber, Anyway?

what is fiber

Without delving into a biochemistry discussion, fiber is a type of carbohydrate that can’t be digested by the body (note that some animals digest carbohydrates more effectively than others – dogs aren’t especially good at it, but they get by). Fibers are more-or-less passed through the digestive system intact.

So if fiber can’t be digested by the body, why is it good for us?

Well, moderate amounts of fiber influence your dog’s biology in a number of beneficial ways while making its way from the entrance to the exit. For example, fiber helps to regulate intestinal function, promote colon health, slows the absorption of glucose into the blood and support healthy gut flora.

But not all fibers are created equal, and they differ in several important ways.

The most important distinction that the average dog owner should know concerns the fiber’s ability to absorb water.

You may have heard this distinction characterized as soluble or insoluble fiber.

  • Soluble fibers absorb lots of water.
  • Insoluble fibers absorb relatively little water.

This small distinction alters the way fiber interacts with your dog’s body. While both are clearly beneficial, soluble fiber is usually preferable because it absorbs water in your dog’s digestive tract and passes relatively easily through her digestive system.

How Much Fiber Is in Dog Food?

Most regular dog foods have fiber contents in the 2% to 5% range. So, while there is no governing body that establishes rules for the term “high fiber,” we’ll consider any food with more than 5% fiber content to be a “high fiber food.”

Because fiber contents in excess of 10% or 12% are potentially problematic, “high fiber” dog foods typically have between 6% and 10% fiber content.

While fiber values can vary quite a bit in dog food, fiber is relatively inexpensive, so manufacturers are generally eager to provide as much as owners are interested in (this isn’t just for your dog’s benefit, as some manufacturers may try to reduce the amount of expensive protein or fat in your dog’s formula in favor of fiber).

Common Sources of Fiber for Dog Foods

apples for dogs

A few of the most common sources of fiber in commercial dog foods include (in no particular order):




Whole grains

Psyllium husk

Beet pulp



You’ll generally want your dog’s food to be based off high-fiber carbohydrates, as opposed to carbs that provide a ton of calories and relatively little fiber, such as refined grains.

Brown rice is better than white, whole grains are better than their processed counterparts.

Quality Dog Food Checklist: The Must-Haves

dry dog food

Whether you are searching for a food that addresses a specific nutritional need or you are just looking for a good all-around option, you should always be sure to provide your dog with a high-quality food.

Generally speaking, this means you want to look keep the following things in mind:

Opt for foods that list a whole protein as the first ingredient. Dogs are omnivores, who remain healthiest on a diet containing a variety of fruits, vegetables, and whole grains, but the bulk of their calories should come from protein sources. Dogs are not obligate carnivores in the sense that cats or rattlesnakes are, but they should still be provided with a meat-based diet.

Avoid foods with unidentified (or poorly identified) meat meals or byproducts. There is nothing inherently wrong with meat meals or byproducts; in fact, many contain a wealth of nutritional value. Your dog will actually enjoy health benefits from eating the cartilage, connective tissues, livers, gizzards and other organs that makeup meat meals and byproducts (although it may make your own stomach a bit squeamish). While beneficial, these food items must always be identified by a single species. In other words, you must avoid things like “meat meal” and “poultry byproducts,” but foods with “duck meal” or “pork byproducts” are perfectly acceptable.

Avoid foods with artificial colors or flavors. Artificial colors and flavors are completely unnecessary for foods comprised of nutritious ingredients. Your dog doesn’t care what color her food is, and good ingredients taste good without artificial enhancers. And while these ingredients aren’t exactly dangerous, they can trigger dog food allergies.

Look for foods that provide health-enhancing nutrients, such as omega fatty acids and antioxidants. Omega fatty acids (particularly omega-3 fatty acids) provide a number of health benefits, ranging from reduced inflammation to good coat condition, while antioxidants help support immune function, among other things.

Try to select foods manufactured in a country with high food-safety standards. This will help limit the potential hazards that may be lurking in your dog’s food. In practice, this means choosing foods manufactured in the USA, Canada, Australia, New Zealand or Western Europe.

Look for foods that contain probiotics. Probiotics are beneficial bacteria that help to promote proper intestinal function. When combined with a high-fiber diet, they pack quite the one-two punch. Opt for a dog food with probiotics included in the formula for a super stomach-friendly meal.

Health Conditions High-Fiber Dog Food Can Help Treat

fiber for obese dogs

Given the diverse array of benefits foods with high fiber content can provide your dog, it shouldn’t be surprising that these diets can become a key tool in the treatment of a number of health problems.

Some of the most noteworthy health conditions fiber can help treat include:


In addition to the role high-fiber diets can play in reducing the number of calories your dog consumes, fiber can help promote a healthy intestinal flora, which is thought to help combat weight gain and accelerate weight loss.

Intestinal Dysfunction

As explained earlier, fiber helps to curb most types of intestinal dysfunction.

You should always consult your vet if your pooch exhibits long-term intestinal problems of any type, but you can rest assured that your vet will probably discuss your dog’s fiber intake, and recommend increasing it, if you are not already providing a high-fiber diet.

Anal Gland Problems

Fair warning: This is going to get graphic.

Dogs have a pair of anal glands located at roughly the 4- and 8-o-clock positions around their anus. These glands produce a waxy, foul-smelling secretion (I warned you), that is normally released during the course of a normal bowel movement.

However, these glands occasionally become clogged, leading to impacted anal glands which can cause a dog pain, along with a host of other problems. This is one of the most common reasons dogs “scoot” across the floor, dragging their butts.

Obviously, this is a problem to be avoided. Fortunately, fiber is once again here to save the day. Fiber helps bulk up your dog’s stools, and this can help put more pressure on the anal glands.

This, in turn, can help ensure that the anal glands are expressed and emptied regularly.

Alternative Ways to Add More Fiber to Your Dog’s Diet

high fiber dog food

Of course, you don’t have to switch to a high-fiber food in order to get your dog more indigestible plant material in his diet.

You can also add a few household food products to help jack up the fiber content of your dog’s regular food. Some of the best ingredients for doing so include:

Canned pumpkin

Green beans



Bran flakes


High-Fiber Vegetables

Always incorporate these ingredients carefully and in moderation. Start by introducing very small quantities of these ingredients (for example, I only need to add about a teaspoon of pumpkin puree to my 90-pound pup’s dinner to firm up her poops).

Be sure to keep plenty of fresh, cool water available for your pup when increasing the fiber content of his food. And, as always, keep your vet in the loop about any dietary changes you make.

    great article! I have a maltese/shitzu who has anal gland issues. She was getting them cleaned at the vet every 2 weeks, soft poop. We discovered a high fiber food, which helped, but still soft poop, so vet every 3 or 4 weeks for cleaning. We now know she is allergic to chicken, hence soft poop, so took her off the high fibre, 12%, food, now eating lamb base food, fiber only 4%, she is back to every 2 weeks needing to get them emptied. I’m at my wits end. When they are full, she “leaks”, a horrible smelling liquid, she licks where she has leaked, she gets so embarrassed. Any suggestions would be so greatly appreciated!!

      Hey there, Lynn.
      So sorry to hear about the problems with your pooch!

      Obviously, you’ll want to work with your vet on this issue and heed the advice he or she provides. But is sounds to me like your pupper needs to go back to a food with higher fiber content — you just need one that’s lamb-based.

      Wellness Core comes in a lamb version. It only has 6.5% fiber content, but that’s at least a step in the right direction.

      Nutro Lite Weight also comes in a lamb version, and it boasts 11% fiber content.

      Let us know if either of those work (and again, talk about the change with your vet first)!

    why are the top 2 options grain free? are you not aware of the connection between grain free dog food and developing heart disease in dogs? with so many other options for high fiber diets, choosing grain free options as your #1 and #2 is very disappointing and dangerous for the dogs of the owners that read your article.

      Hey there, Adam. We are aware of the documented correlation between DCM and grain-free foods, and we’re shifting our recommendations as quickly as we can.
      Thanks for checking out the site and sharing your thoughts.

    My senior dog has a potato allergy. Needs more fiber but so many foods contain potato. What’s the alternative.

    Thank you so much for this article. My vet recommended a high fiber diet for my rough collie’s chronic diarrhea. She prescribed Hill’s Gastrointestinal Rx food, which did firm up the diarrhea quickly (so the increased fiber seemed to be the answer). But, reading the ingredients: corn, corn gluten and pecan shells! – I did NOT feel good about keeping her on this diet long term. I’m grateful there are other products out there with healthier ingredients for long term health.

    My dog is overweight vet said add more fiber to her diet problem is all high fiber dog food has some kind of chicken in it she allergic to chicken any suggestions

      Hey, Peggy.
      That’s a tough one — all of the ones we reviewed do have some type of chicken-based product. You may want to consider asking your vet for a recommendation.
      Failing that, you may be able to simply use your normal (low-fiber) food, but add a high-fiber ingredient or supplement to it. But we’d definitely encourage you to do so with your vet’s guidance.
      Best of luck!

        The “Blue Wilderness Rocky Mountain Recipe with Red Meat—Healthy Weight” is 10% fiber with no chicken! My poor doggo has gland issues and needs the high fiber, but chicken-based foods and treats make her chew her paws like crazy! The only problem is that it has been a little hard to get lately…

    My 16 month rescue pup who is is great physical shape, vet is very happy with her weight and muscle development, etc. has always had trouble with the anal glands leaking. The vet has assisted with them and so has her groomer. It is terrible and she is always licking at her backend.
    We feed her a very good food Merrick and I also give her carrots and real pumpkin.
    Please, any suggestions? Should I switch food?
    Thank you…

    My dog has allergies and is allergic to chicken. Also I recently have been seeing article after article stating that legumes, peas and etc are bad for dogs. I also read that potatoes aren’t good for them. So can you help me with a good food that doesn’t contain those items I would be more than greatful.

    Hi! I came across this article and just wanted to add that high-fiber treats are a great addition as well. Purely Dog is carob fruit for dogs — really high in fiber — and makes great poops!

    We just found out that our dog has diabetes and she has been getting insulin shots since May. They really havent been droping her blood sugars that much but we are stilling trying to figure out her dosages. It has been recommended that she go on a high fiber diet and in the article you recommended Blue Wilderness. I am certainly going to look into this but do u have any recommendations for websites that I can go to to educate myself on the whole dog diabetes thing bc I have had dogs my whole life and have never had one that is diabetic so this is all new to me.

    1. Ben Team Avatar

      Hey, Betty. Sorry about your pupper’s diagnosis.
      You may want to give our article about dog foods for diabetic dogs a read. We provide a lot of information there about the disease and recommend nine different foods that you may want to consider.
      Best of luck!

    I loved this article. But i have a problem my dog is toothless and has a liver problem. The vet pot get Hills which I don’t agree with. Can you give me a list of high fiber can food.. Thank you.

    1. Ben Team Avatar

      Hey, Wanda. So glad you found the article helpful.

      I’d suggest asking your vet about mixing in a little pumpkin puree with your pup’s food. Pumpkin puree is full of fiber and most (well, many) dogs like the taste.

      Just be sure to verify that it’d be safe to do so with your vet. Pumpkin is generally safe for dogs, but given his/her health issues, you’ll want to double check.

      Best of luck! Let us know how it goes.

    My two year old beagle has anal gland issues. Have tried many foods and he does not like a chicken flavor based dog good. Right now on ProPlan Lamb and Rice which is eats without hesitation. Would pumpkin help added to his food or sweet potato be better. Expressing his glands every 10 days to two weeks. Wasn’t a problem when on puppy food.

      When my dog’s anal gland acts up I add pumpkin to his food. It clears the problem.

    Very informative…Thank you so much…!!! I am very impressed how detailed your article is in regards to High Fiber diet and your recommendations. I have been feeding my shih tzus (10 months and 7 year old pets) grain free kibble dog food…. I went from ” Iams”, to “American Journey (grain free)” to ” I Love and You (grain free)”…. With great disappointment I am learning that the FDA is warning pet owners about the disadvantages of grain free diet with reference to its link to Dilated Cardiomyopathy (DCM) – warning that it is associated to the consumption of legume seeds, peas, lentils or potatoes. What is your say about this? I am looking into getting Wellness, Blue Wilderness Blue Buffalo, but my question for you is, will this be good for my Shih Tzus? The reason why I ask is because, some manufacturers make dog food specific for Shih Tzus. Please help me make a good decision.

    Thanks for the info. As much as I love my Bella girl I am on a fixed budget is there a dog food that is medium priced. She likes the food I give her but she likes to eat grass. I am moving to a place where that won’t be available.

    Proper nutrition is critical for your dog’s health and ability to live a long and full life. I think who loves his dog and who want to be sure they are giving the right nutrition. So, thanks for your great blog. This blog will be of great benefit to those who love their dogs. Just like me.

    My dog has been diagnosed with diabetes and we are not going to give him shots I feel it is to hard on the dog and not fair to him since they do not understand why they are constantly being poked. My vet said to do the high fiber diet so I will try the blue buffalo. And cut back on carbs and sugar. Any other advice

    (Royal Canin Veterinary Diet Satiety Support Dry Dog Food) When I first got my dog, a GSD/Husky, I don’t think he came from a really good environment. He had almost constant diarrhea. We took him to the Vet and he found some intestinal bacteria. Besides some shots and some medicine we had to give him for a week, he also prescribed the aforementioned dog food. He was only supposed to have it for a month or so, -but- it could be used as a “treat” thereafter. Well, he is now 2 1/2 years old and still eating the dog food as a treat. We have called it our “fiber” food ever since we first got it. Now I see your article advertising the same brand, but a different version. My Dakotah doesn’t really like dog food for his meals. -But- he loves it for treats and that is what he gets on our walks. For the most part his stools are solid. So I do believe he is getting enough fiber. By the way, you can only get this particular version of Royal Canin through a Vet. And thanks for your excellent article. Think I will start throwing in a couple of carrots to his diet.

      Thank you Chuck! Good to hear that Royal Canin is working for Dakotah. In truth the gold standard dog food can be different for every canine. Glad you took the time to find what works best for your buddy!
