Benefits of High Fiber Dog Food

You’re probably well aware of the many benefits a high fiber diet offers for you, but what about for your dog?

To find out, we first need to find out exactly what fiber is and examine the important role it plays in the digestive system.

What is fiber?

Fiber is an important nutrient for your dog’s overall health and wellbeing. This type of carbohydrate is found in plant-based ingredients and comes in two different forms: soluble and insoluble.

Soluble fiber dissolves in water and can be digested. Insoluble fiber cannot be digested by the body and passes through the gastrointestinal system more or less unchanged. 

Both types of fiber have their uses, and both can provide a wide range of advantages for your dog. Some of the benefits of high fiber dog food are listed below.

It ensures proper digestive function

The number one-benefit of high fiber dog food is that it helps your dog’s digestive system function properly.

Fiber regulates digestive function, ensuring that your pet is able to properly digest and absorb all the essential nutrients in his food. It also helps the good bacteria in your dog’s gut thrive, ensuring that illness and disease are kept at bay.

It prevents diarrhea and constipation

When your dog’s digestive system is working properly, his bowel movements will also be normal. This helps prevent problems like constipation, bloating and diarrhea.

It boosts the immune system

Fiber also nourishes the good bacteria in your dog’s digestive system, helping to ensure proper digestive balance. And with up to 70 percent of your dog’s immune system linked to the gut, including fiber in your dog’s diet can promote general health and wellbeing.

It aids weight loss

When shopping for high fiber dog food, you’ll probably notice that many fiber-rich recipes are designed to help your pet lose weight.


It all comes down to the fact that high fiber foods can help your dog feel full for longer.

These low-fat diets let your dog feel like he’s eaten a hearty meal, but at the same time ensure that he eats fewer calories.

It maintains healthy blood sugar levels and prevents diabetes

Next, the best high fiber dog food can also reduce your dog’s risk of diabetes. They do this by helping to maintain blood sugar levels within a healthy range, lowering the chances of any dangerous fluctuations.

This not only makes it easier to manage your dog’s diabetes but also helps prevent obesity.

It reduces anal gland inflammation

The best high fiber dog food can also prevent anal gland problems. Fiber helps your dog produce firmer, bulkier stools, which assists with naturally draining the anal glands when your pet does his business.

Reduces the risk of cancer

Because fiber helps your dog produce stools more quickly, it’s thought that it may also help reduce the risk of colon cancer.

Sources of Fiber for Dogs

Now that you know just how important fiber is for your dog, where can you find the best fiber foods for dogs?

The good news is that there are several ways to increase fiber consumption.

You can feed a high fiber dog food, give your pet specific ingredients known to be high in fiber, and even use fiber supplements for dogs.

Sources of fiber in dog food

There are several fruits, vegetables, and grains commonly used in commercial dog food to increase fiber content. These include:

  • Sweet potato
  • Pumpkin
  • Apple
  • Carrot
  • Oatmeal
  • Flaxseed
  • Psyllium husk
  • Brown rice
  • Beet pulp
  • Legumes

How to add more fiber to your dog’s diet

If you want to add more fiber to your dog’s diet without switching to a high fiber food, you may want to consider giving him healthy, high fiber treats.

Happily, there are plenty of “human” foods that can also make nutritious treats for dogs. Some examples include:

  • Canned pumpkin
  • Raw or steamed green beans
  • Cooked sweet potato
  • Peas
  • Raw or cooked carrots

Whichever ingredients you choose, be sure to give them only in moderation and monitor your dog for any signs any of these foods don’t agree with him.

How Much Fiber Is In Dog Food?

What constitutes a high fiber dog food?

To find out, you’ll need to take a closer look at the label.

How much fiber is in regular dog food?

If you’re reading this, you’re probably wondering, how much fiber does my dog need?

Most dog foods contain somewhere between 2% and 5% fiber. For most dogs, this provides sufficient fiber to ensure good health and proper digestive function.

You can find out how much fiber is in your dog’s food by reading the guaranteed or typical analysis on the label.

How much fiber is in high fiber dog food?

High fiber dog foods usually have a fiber content of 5-12%. However, many of these foods are designed to perform specific tasks, such as aiding weight loss or ensuring minimal digestive problems for dogs with sensitive stomachs.

As a result, it’s important to check with your veterinarian before feeding a high fiber dog food.

What to Look For In High Fiber Dog Food

There are several important factors you’ll need to take into account when searching for the best high fiber dog food for your furry friend.

First, you’ll need to consider your dog’s nutritional needs so you can be sure of choosing appropriate food.

For example, puppy foods are specially formulated to meet all the nutritional requirements of puppies, while adult foods provide all the vitamins and minerals an adult dog needs to stay happy and healthy.

Foods are also developed for dogs of different sizes, so if you own a large breed like a Labrador or Golden Retriever, you’ll need to feed a diet designed for large breeds.

Best high fiber dog foods comparison

The easiest way to find the right food for your pet is to compare high fiber dog food brands. You’ll need to consider:

  • How long the brand has been in business
  • Where the food is manufactured
  • Reviews from other customers
  • What quantities the food is sold in
  • How much it costs
  • Whether it’s designed for any specific goal, such as aiding weight loss

This should give you a better idea of which dog food brands and specific products could be suitable for your dog. The next step is to take a closer look at the label of any high fiber food you’re thinking of buying.

Reading dog food labels

Have you ever looked at a dog food label and felt completely overwhelmed by the information it contains?

To help make buying high fiber dog food a little less confusing, here are a few key factors you need to look at when reading dog food labels:

  • Complete and balanced. There are some pretty complicated rules and regulations surrounding what pet food manufacturers can and can’t say on food labels. However, under these regulations, any food labeled as “complete and balanced” must be able to provide all the nutrients your dog needs. Look for a statement of nutritional adequacy in line with the Association of American Feed Control Officials (AAFCO) requirements.
  • Ingredients list. Ingredients on dog food labels are listed in order of weight, so the first item listed is the major ingredient in the food. Look for a quality source of animal protein to be first on the list, and examine the top three ingredients to learn what makes up the bulk of the food.
  • Guaranteed analysis. This section lists the percentage of crude protein, crude fat, crude fiber, and moisture. If you want to know exactly how much fiber is in the food, you’ll find that info here.

Ask your vet

When in doubt, ask your trusted veterinarian for advice. Not only will your vet have an in-depth understanding of your dog’s nutritional needs, but they’ll also be able to recommend specific brands and foods.

Your vet can also offer tips to help you safely transition your dog to his new diet.

Can Too Much Fiber Be Bad for My Dog?

While fiber offers plenty of health benefits for your dog, it’s also possible to have too much of a good thing.

Too much fiber in your dog’s diet can lead to excess stools, very smelly gas, and even hamper the body’s ability to absorb nutrients, so it’s important to control how much your dog consumes.

Can high fiber dog food cause diarrhea?

If approved by your vet and if you make the transition slowly, high fiber dog food shouldn’t cause any digestive issues for your pet.

However, too much fiber can lead to excessive defecation and diarrhea, or even prevent essential nutrients from being properly absorbed. That’s why it’s important to ask your vet for advice before switching to a high fiber food for dogs.

Switching to a High Fiber Dog Food

If you’ve decided it’s time to switch your dog to a high fiber diet, take it slow. A sudden change in diet could cause an upset stomach for your pooch, potentially leading to vomiting and diarrhea, so you’ll need to introduce the new food gradually.

How to change to a high fiber diet

To give your dog’s stomach time to adjust, start by mixing in the high fiber food with his current diet — a ratio of ¼ new food to ¾ existing food is a good starting point.

After a couple of days of this, switch to a 50/50 ratio and then gradually increase the amount of high fiber food.

By slowly shifting to a high fiber diet, you’ll hopefully avoid any gastrointestinal upset.

Frequently Asked Questions

2. Should I give my dog fiber supplements?

Over-the-counter fiber supplements provide an easy way to add more fiber to your dog’s diet.

However, whether or not supplements are suitable depends on your dog’s health, age, and a range of other factors, so consult with your vet before giving any supplements to your dog.

3. Why are low-fat dog foods often high in fiber?

Final Thoughts

Fiber is an important nutrient for all dogs, but not every canine needs high fiber dog food. For many dogs, food with 2-5% fiber will be adequate for all their nutritional needs.

However, if your dog suffers from digestive problems like constipation, or if he needs to lose some weight, a high fiber diet can be beneficial.

Talk to your vet for advice on what to feed your dog, and compare a variety of products to find the best high fiber dog food for your pet.
