If I didn’t know better, I’d think that dietary fiber had the best lobbying apparatus in the civilized world!
Everywhere you look, you see studies explaining the health benefits of fiber for one bodily system or another. And as it turns out, our dogs enjoy many of these same benefits!
This leads many owners to seek out a high-fiber food for their pooch. Before you click-and-pay for the first high-fiber food you see, take a moment to educate yourself about high-fiber dog foods (don’t worry, we’ll explain everything you need to know).
We’ll even recommend five great choices for you, and explain why they’re among the best options. Read on!

What Is Fiber, Anyway?
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 fiber 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 easy 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
A few of the most common sources of fiber in commercial dog foods include (in no particular order):
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.
The Benefits of High-Fiber Dog Foods
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!
Quality Dog Food Checklist: The Must-Haves
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
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.
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 pain and 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, which can often ensure they empty regularly.
Because of the way in which fiber helps to regulate blood sugar levels, it is often helpful in the management of diabetes. It may even help prevent Type-II diabetes, as it helps reduce food intake, although Type-II diabetes is not terribly common in dogs.

CONS: The biggest single problem with Royal CANIN Gastrointestinal Fiber Response is its reliance on chicken by-product meal as the primary protein source.

Most Blue Wilderness recipes are really good, and their Healthy Weight Chicken Recipe fails to disappoint. It’s packed with everything you’d want in a premium dog food, including whole proteins, several sources of omega fatty acids, and probiotics.

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