However, the fiber mostly comes from plant-based ingredients, but you can add it into the dog’s diet through ingredients such as peas, green beans, and sweet potatoes.

In this blog post, we will discover the types and benefits of fiber and help you choose the best high-fiber foods for your pup! Read on for more information!

Types of Fiber

Dietary fiber includes plant food that is not easily digested by the body but is very beneficial in regulating bowel movements. It has two forms such as soluble and insoluble fiber.

Soluble Fibers

Soluble fiber easily dissolves in the water and helps lower cholesterol levels and control blood sugar levels. It can produce intestinal gas or diarrhea if consumed in large amounts or when it is first time added to a dog’s diet. To reduce these side effects, start with small doses and increase gradually.

Insoluble Fibers

Insoluble fiber does not easily dissolve in the water and helps constipation and the digestive system. Insoluble fiber is generally harmless in high doses. Still, too much can reduce the diet’s nutritional value by binding minerals, leading to diarrhea, vomiting, weight loss, poor coat quality, and even flatulence.

However, you must look for an insoluble fiber in dog food as it provides many benefits to the dog.

Benefits of Fiber

Dog foods must contain fiber to provide the following benefits to your dog:

  • Helps weight management
  • Improves the bowel system
  • Prevents constipation
  • Reduces bloating
  • Supports the immune system
  • Lowers the risk of colon cancer
  • Fights against infection and illness
  • Aids to healthy digestion
  • Improves diabetes mellitus

What to Look for When Choosing the Best High Fiber Dog Food

When looking for the high fiber dog diet, you need to consider the following things:

  1. Always look for whole grains such as oatmeal and brown rice.
  2. Consider having whole fruits and vegetables.
  3. Avoid refined grains such as wheat and corn.
  4. Look for healthy ways of getting fiber.
  5. You can have a supplemental source of fiber, such as psyllium husk and flaxseed.

Natural Sources of Fiber

There are many sources of adding fiber to a dog’s diet. Here are some natural sources of fiber listed below:


Pumpkin puree is a natural and healthy source of fiber. It contains dietary fiber of 7.1 grams per cup. You can use it as a topper to the dog’s food. When you add it to a dog’s food for the first time, just add a teaspoon for safe consumption.

Beet Pulp

Beet pulp, a colorless byproduct of sugar beet, is found in many high-fiber dog foods. The fiber content of beet pulp ranges from 11-to 19%. Dogs can easily digest the beet pulp.

Ground Flaxseed

Ground flaxseeds are a great source of fiber, containing 2 grams per tablespoon. It has omega-3 fatty acids that are good for a dog’s coat, skin, brain, and nervous system. You can add flaxseed into a dog’s diet by sprinkling it on the food or putting it into a treat-dispensing toy.


Baby carrots are considered the most healthy snack for dogs and are added mainly by the food brands in their recipes. Carrots are high in fiber, contain 2.8 grams, and benefit kidney and liver health.


Most dogs love to eat apples, and many owners feed them as it has extra fiber. An apple has 3 grams of fiber and is beneficial for a dog’s teeth health. You must not feed your dog many apple slices due to their high sugar content, and avoid its core and seeds.

Dark Leafy Green Vegetable

Dark leafy green vegetables contain 0.5 to 2 % grams of fiber in every cup. If your dog loves eating them, cut the vegetables into small pieces for easy digestion.

Brown Rice

Brown rice is an excellent source of fiber, containing 3 grams per cup. Many commercial food brands use brown rice in their dog’s weight management recipes.


What Is High-fiber Dog Food?

Dog food usually contains 2 % to 5 % fiber content. However, if there is 10 % to 12 % fiber present in dog food will be considered a high-fiber dog food.

Do Dogs Really Need Added Fiber?

Most dogs get an adequate amount of fiber from their regular food. However, some dogs may need added fiber if they have loose stools or digestion problems. Always ask your vet to determine the amount of fiber in your dog’s food.

How Much Fiber Does My Dog Need?

An adult dog’s diet must contain a 2.5 to 4.5 % fiber content. While the fiber helps regulate the bowel movements and supports the dog’s health, too much fiber can cause diarrhea and excessive gas. It is best to consult a veterinarian to decide the amount of fiber content.


A high-quality fiber source is essential; you must look for whole fruits and vegetables for an adequate amount of fiber. It helps prevent obesity in dogs.

Fiber-rich diets may help some dogs lose weight and are probably good for their digestive health. This allows dogs to feel full and satisfied without intaking many calories.

The average diet of adult dogs usually has 2.5 and 4.5 % fiber content. However, some dog foods contain more fiber than the prescribed ratio. The 10 % fiber in food is safe but try not to overdose the dog as it may lead to health issues.

The consumption of fiber-rich diets may also help control hyperglycemia (high blood sugar levels) and improve the overall function of the large intestine. In contrast, too much fiber can reduce the digestion of other essential nutrients and cause loose stools, frequent feces, and poor palatability.

Before adding new food or nutrients to the dog’s diet, always consult your veterinarian!
