The best high fiber dog food is the Nutro Natural Choice Dry Dog Food as the best one, in case you’re in a hurry and just want to find out what our top recommendation is.

When you think of dog food, you probably think of meat. After all, dogs are carnivores, and they need a primarily meat-based diet to survive. However, to thrive, they also need fiber.

Fiber helps dog digestive systems operate at the highest level. For dogs with specific health problems, a diet high in fiber can help keep them healthy. However, it’s not always easy to know what type of high-fiber diet will work best.

Today, let’s take a close look at the best high fiber dog food. You can check out five mini-reviews of products that can help below and then read an easy-to-understand guide on selecting the right food based on your dog’s specific needs.

Guide to High Fiber Dog Food

Dogs get most of their nutrition from animal sources, but they have a limited ability to absorb nutrients from plant-based sources, too. Fiber is a necessary part of a healthy diet for dogs. Let’s take a closer look at what fiber is, what it does, and how much your dog needs.

What is Fiber?

Fiber is an indigestible carbohydrate material. It’s found in cell walls, which aren’t a part of animal cells. Instead, fiber is only found in plant-based materials. Common fiber sources include fruits, vegetables, grains, and seeds. It has a variety of health benefits, most of which are related to digestive function.

Fiber is divided into two types:

  • Soluble
  • Insoluble

Each has different benefits. Here’s a closer look:


This type of fiber dissolves in water. Some types of water-soluble fiber are also prebiotics.

A dog’s digestive system doesn’t do much with soluble fiber on its own. Instead, the fiber acts as food for bacteria that live in the large intestine. The bacteria break the fiber down into short-chain fatty acids, also known as volatile fatty acids.

These fatty acids provide valuable energy for digestive system cells. When the digestive system uses this energy, it operates more efficiently and effectively. Gut health, immune system function, and digestion all improve.

On the downside, when the bacteria consume soluble fiber, fermentation occurs. Fermentation in the gut often leads to excess gas. However, gas is often minimized if fiber is introduced slowly into your dog’s diet.


Dogs can’t digest insoluble fiber. Instead, it passes through the digestive system unchanged and unaltered. At first, this might not sound like much of a benefit, but it’s actually incredibly effective at stimulating the gastrointestinal tract.

Unlike soluble fiber, the insoluble type can be introduced quickly into your dog’s diet. That’s great news if your dog suffers from an occasional bout of constipation or diarrhea. Insoluble fiber doesn’t produce fermentation, so it doesn’t cause excess or other gastro issues.

What Foods Have the Best/Most Nutritious Fiber?

You’ll find no shortage of foods that proclaim something like they’re “high in fiber” or “contain 100% of your dog’s fiber needs.” Beware of marketing hype. You want to read the ingredients carefully to see what foods the fiber is derived from.

Fiber has different properties based on its source. Many less-than-stellar manufacturers use bulky fiber that boosts the overall weight of the food bag but provides little in the way of nutrition.

Excellent sources of soluble fiber commonly found in dog food:

  • Oats
  • Beans (Legumes)
  • Barley
  • Rice
  • Beets
  • Apples

Excellent sources of insoluble fiber commonly found in dog food:

  • Wheat bran
  • Oat Bran
  • Potatoes
  • Cereals
  • Carrots

Watch out for dog foods with an abundance of peas. While they’re a source of fiber, they typically don’t have as much fiber as many other sources. Peas are one of the most common sources of filler in dog foods.

Additionally, while fruit is often an excellent source of fiber, you want to avoid foods with a high fruit content when feeding a diabetic dog. However, other types of fibers do have benefits for a diabetic dog, and we’ll cover those in a further down.

The Benefits of High Fiber Diet

Generally, fiber benefits the entire gastrointestinal system. More specifically, a high-fiber diet is usually used to treat the following canine conditions:


Insoluble fiber is an effective treatment for both short-term and chronic constipation. The dog’s digestive system can’t digest it, so it passes through the entire intestinal tract. As it moves through the colon, it collects moisture from outside the colon. The moisture helps stool move out of the body.

Pumpkin and oats are often good choices if you need immediate constipation relief, while any of the sources of insoluble fiber listed above work well to keep your dog regular.


Although it seems counterintuitive, fiber treats both constipation and diarrhea. It’s what’s called a “stool normalizer.” Increasing fiber content is usually the first strategy when faced with any problem related to irregular bathroom habits.

When used to treat diarrhea, fiber absorbs water from inside the colon, which helps solidify the stool. As with constipation, pumpkin is also an effective treatment for diarrhea.

Anal Gland Issues

Canine anal glands secrete a strong-smelling liquid. It’s emitted whenever your dog has a bowel movement or rubs his rear against the ground. Expressing anal glands has two benefits:

  • It helps a dog mark his territory
  • It helps lubricate his stool

Sometimes, anal glands can become impacted or too full. If the dog has difficulty expressing his glands, he’ll become uncomfortable. You’ll want to have your dog’s anal glands checked out by your vet as part of routine health care.

An occasional blockage usually isn’t cause for concern. However, frequent blockage often indicates a gastrointestinal issue. You’ll want to increase your dog’s intake of both soluble and insoluble fiber.

Colon Cancer

A high fiber diet helps reduce the risk of colon cancer in dogs. By keeping your dog’s bowel movements regular, waste doesn’t have a chance to linger in the colon, where toxins are exposed to the intestinal walls. As exposure to toxins is reduced, so is the risk of developing colon cancer.

Pay attention to any changes in your dog’s bathroom habits. Both frequent constipation and diarrhea can be early warning signs of colon cancer in dogs.


Insoluble fiber helps combat obesity. It works by adding volume to the food, a concept also known as diluted calorie content. As the fiber absorbs water in the intestinal lining, the dog’s digestive system sends a signal to the dog’s brain that he’s not hungry anymore.

Basically, high-fiber foods make dogs feel full faster than low-fiber foods. Additionally, they feel fuller longer, and with no loss in overall nutrition.


High-fiber foods can help control diabetes. Fiber slows the breakdown of food, which, in turn, helps reduce spikes in blood sugar. A steady high-fiber diet is often part of a larger plan for controlling a dog’s diabetes.

However, if your dog has diabetes, always talk to your vet before switching your dog to a high-fiber diet. Not every diabetic dog benefits from this type of diet. You and your vet will develop a diabetes treatment plan together.

Pancreatic Insufficiency

Exocrine pancreatic insufficiency (EPI) is a fairly common digestive issue in dogs. The pancreas, due to genetics or illness, becomes unable to produce specific enzymes. The body’s ability to absorb nutrients from food suffers, resulting in a variety of health problems.

Soluble fibers help make the food easier for the body to break down and absorb. However, it’s a delicate balance. Dogs with EPI can’t have a diet too high in fiber, so you’ll need to work with your vet to determine what’s right for your dog’s specific situation.

How to Switch Your Dog’s Diet

Never immediately switch out your dog’s current diet with a new one. Instead, changing diets should take about a week or more.

Mix increasing portions of the new food into the old. Note that you’re not increasing your dog’s daily food consumption. For example, if he normally gets a cup of food each day, you’ll give him a quarter-cup of old food mixed with three-quarters of a cup of the old food.

The American Kennel Club recommends the following schedule:

  • Day 1: 25% new / 75% old
  • Day 3: 50% of each
  • Day 5: 75% new / 25% old
  • Day 7: First day of 100% new

Seven days is only a guideline. If your dog has any health issues, especially related to gastrointestinal disease, you’ll want to lengthen the transition period. Doubling the time, and allowing the dog’s system to grow accustomed to each blend, helps prevent stomach upset and related issues.

What is a High Fiber Diet?

Most regular dog food has a fiber content between 2% to 5%. That’s usually fine for healthy dogs. However, if they develop any of the issues above, you’ll want to up the fiber content in their food.

Specifics vary by brand, but high-fiber dog foods typically have a fiber range from 5% to 8%. If your dog has specific, usually serious issues, your vet might prescribe high-fiber food with a fiber content as high as 12%.

Additionally, supplements are available. You can find high-fiber treats, or simply feed your dog high fiber foods such as pumpkin or apple slices.
