5 Best High Fiber Dog Foods for Healthy Digestion REVEALED

Fiber is equally as necessary as protein, carbs, and lipids in the right amounts.

Dietary fiber is essential for the bacteria and cells lining your dog’s intestines and also absorbs certain toxins, which helps to prevent their entry into circulation. 

Owning a dog means that you take care of his food and nutrition, giving him a complete and balanced diet, but it can be tough to find a high-fiber dog food that your dog will eat.

We have picky pups too, so we set out to find and test the highest-rated high fiber dog foods available.

After our testing, we compiled this list of the 5 best high fiber dog foods, plus another 5 that we felt were worth an honorable mention.

How We Chose the Best High Fiber Dog Food

best high fiber dog foods

Fiber provides essential nutrients to the bacteria and cells in your dog’s colon, allowing him to thrive. Fiber also prevents certain poisons from entering the bloodstream.

Because not all fiber is made equal, it’s important to understand which types are best for your dog’s whole body. 

If your dog is a picky eater, he may not be able to consume all high-fiber dog foods because of his preferences. With a little perseverance, you should be able to discover a high-fiber dog food that your dog will like. 

Fiber provides many of the same benefits to dogs as it does to people – it helps the digestive system operate more efficiently.

REMEMBER: It’s important to transition slowly when changing your dog’s food. Quick changes can upset sensitive stomachs.

Another positive of increasing fiber in your dog’s diet is relieving constipation.

Fiber draws water into the gut and contributes to the volume of your dog’s feces, which may aid in the maintenance of smooth digestive function even further.

On the flip side, if your dog eats too much fiber, it may poop more often (and pass gas more than usual).

With all the benefits in mind, we set out to find the best high fiber dog foods that contained quality ingredients.

We looked for brands that put the quality and health of pets first and put a few non-GMO and superfood options on our list for this reason.

As we mentioned, getting a dog to transition to a different food can be challenging. To combat this, we looked for dog foods with flavors we know dogs will love, like lamb and chicken.

After our testing, these 5 were our favorites. Let’s hop into it!

Best High-Fiber Dog Foods Reviewed

Effectiveness 4/5
Quality 5/5

Size: 30 lb. | Brand: Nutro | Type: Dry non-GMO formula | Flavor: Lamb, Chicken (Optional) | Target Species: Dog | Item Form: Other (Lamb); Dry (Chicken) | Breed Recommendation: Large Breeds (Lamb); All Breed Sizes (Chicken)

What We Liked

  • Foods rich in fiber and antioxidants are vital for healthy digestive and immune systems
  • Nutro Lite provides high-quality components at a low price
  • Dog food that is good for diabetic dogs

What We Didn’t Like

  • It may trigger food allergies in sensitive dogs

NUTRO Lite Adult Dry Dog Diet is a nutrient-dense food with fewer calories to help overweight dogs lose weight and maintain a healthy weight.

This makes it an especially good choice for dogs with diabetes.

This dry meal is strong in antioxidants and natural fiber, which aids digestion in dogs 1 year and older. 

It’s produced with lamb and chicken as primary ingredients and supplemented with brown rice, essential vitamins, and minerals, plus natural fiber for good digestion.

With all of these high-quality, high-fiber ingredients, you can rest assured that you’re feeding your dog nutritious and delicious food!

2. Best Dry Grain-Free Formula: Wellness CORE Dry Dog Food

Product Ratings

Affordability 4/5
Effectiveness 5/5
Quality 5/5

Size: 26 lb. | Brand: Wellness | Flavor: Turkey | Target Species: Dog (Adult) | Item Form: Dry | Breed Recommendation: All Breed Sizes

What We Liked

  • May help to alleviate poor digestive symptoms including diarrhea, gas, and vomiting
  • It may benefit dogs’ coats and anal sac health, while the high-quality protein helps create strong muscles that promote joint health and mobility
  • With a variety of flavors, dogs never get bored of it

What We Didn’t Like

  • Watch for signs of sensitivity, especially in younger dogs. While ingredients are blander than others, transitioning too quickly can lead to an upset stomach.

Most dogs get enough fiber in their food because they have enough fiber-containing ingredients. On the other hand, some breeds may need more fiber than other breeds. You should talk to your veterinarian first to see if your dog’s food needs more fiber.

CAUTION: A lot of fiber at once can make your dog bloat and have diarrhea, so be careful. Striking the right balance is hard, and a gradual transition to the new food is vital.

Our dogs responded well when it was time to test this food.

They transitioned to it faster than other foods, probably because the main ingredient is turkey in a grain-free formula, making it easier on their stomachs.

We love that this formula has much less fat than the original formula and is high in protein and high fiber. This helps dogs to have healthy digestion while building and maintaining lean muscles.

3. Best Dry Formula: Blue Buffalo Wilderness High-Protein Dry Dog Food

Product Ratings

Affordability 4/5
Effectiveness 4/5
Quality 4/5

Size: 24 lb. | Brand: Blue Buffalo | Flavor: Chicken | Target Species: Dog | Item Form: Dry | Breed Recommendation: Medium Breeds, All Breed Sizes

What We Liked

  • Anal gland problems were resolved as a result of this easy-to-digest meal
  • Blue Wilderness Dog Food is developed specifically to fill your dog’s nutritional requirements
  • This grain-free meal contains protein-rich, deboned chicken and life-sustaining antioxidants to provide your dog with the energy it needs to flourish

What We Didn’t Like

  • Grain-free meals might potentially be harmful to certain types of dogs’ health, despite their apparent benefits, according to recent studies

Blue Buffalo Wilderness Dog Food is one of the best high fiber dog foods. This dry food contains protein which accounts for 38% of the total, fat which accounts for 17% and carbs which are 38% of the total.

Industry standards indicate that the brand comprises 36% protein and 16% fat; however, this percentage may differ.

Many foods contain carbs in amounts of more than 40%. We feel that Blue Buffalo exceeds industry standards in all the right ways.

Blue Buffalo Wilderness is 5-star dog food, and our dogs agree with the accolades. It’s easy to get our dogs to eat this high-fiber dog food.

4. Best High-Fiber Dog: Instinct Raw Boost Dog Food

Instinct Raw Boost Dog Food

Product Ratings

Affordability 3/5
Effectiveness 4/5
Quality 5/5

Size: 30 lb. | Brand: Instinct | Type: Dry grain-free formula and freeze-dried raw pieces | Flavor: Chicken, turkey meal, peas| Target Species: Dog | Item Form: Raw, Dry, Frozen | Breed Recommendation: All Breed Sizes

What We Liked

  • Allergy-prone dogs may particularly benefit from it
  • Weight gain and digestion problems may be eased
  • Instinct may help you keep your dog’s weight under control

What We Didn’t Like

  • It’s rather expensive

Based only on its ingredients, Instinct Raw Boost Dog Food seems to be a good dry product.

Lipids account for 23% of protein composition, whereas carbs account for around 29%. The brand’s average protein and fat composition is 38% and 21%, respectively. 

The total carbohydrate load for the whole product range is 33%. An approximate 55% fat-to-protein ratio. This meal is higher in protein than others and there’s a lot of fat there.

This dog food has fewer carbohydrates than a regular dry dog meal. Aside from the peas, this seems to be a meat-heavy feast.

5. Best Powder Formula: The Missing Link All-Natural Dog Supplement

Product Ratings

Affordability 4/5
Effectiveness 4/5
Quality 4/5

Size: 1 lb. | Brand: Missing Link | Type: Powder formula | Flavor: Skin & Coat | Target Species: Dog | Item Form: Powder | Breed Recommendation: All Breed Sizes

What We Liked

  • The Missing Link may be beneficial for dogs that suffer from itching
  • The Missing Link’s superfood supplement boosts colon health
  • Cold-processed ingredients are completely free of GMOs
  • Boosts the nutritional content of any dog food

What We Didn’t Like

  • A few dogs may find the taste or texture unpleasant

After The Missing Link was discovered, there was a greater availability of healthy food than was previously accessible in nature or commercial food.

Simply sprinkle this superfood supplement on your dog’s food to give it a fantastic nutritional boost.

Original Skin & Coat for Canines is created with natural, high-quality whole foods that help enhance the look of your pet’s skin and coat.

While this doesn’t take the place of healthy food in your dog’s diet, it can help give your dog that extra boost he needs.

In order to guarantee that the powdered supplement stays fresh and healthy, it’s nitro-flushed before being vacuum-packed.

This recipe will aid you in maintaining the health of your dog. After they’ve been weaned from their mothers, this meal is appropriate for puppies and dogs of all ages.

The Winner

Overall, we loved Nutro Natural Choice Dry Dog Food – For Dogs Aged 1+. Nutro’s dry formula is made entirely of non-GMO ingredients from trusted sources.

The first ingredient is real lamb, which is what gives this dish its protein, while fiber is boosted with healthy brown rice.

Honorable Mentions

Here’s a brief look at the 5 best high fiber dog foods we tested that didn’t quite make our list.

 1. Solid Gold Grain-Free Dog Food – Considered for Dry grain-free formula

Though not the most budget-friendly option, with Solid Gold, your dog gets a lot of nutrition, and the puffy kibble pieces are low in fat and calories.

The high fiber content makes sure that your dog gets a lot of gut-benefitting nutrients.

Our dogs prefer the flavor of Wellness CORE Dry Dog Food so it took a spot in our list of top picks.

 2. Holistic Select Dry Dog Food – Considered for weight-management issues

This is a fiber-dense combination. You’ll reduce your pet’s chance of colon cancer while also helping him keep a regular bowel movement.

Flaxseed isn’t only a good source of fiber, but it also has skin and coat advantages. The high fatty acid content will give his coat a lovely gloss.

Prebiotics and probiotics help to regulate digestion.

While we love this formula overall, our dogs preferred other kibbles with The Missing Link All-Natural Dog Supplement sprinkled over the top for added nutrition.

 3. Nutrisca Grain-Free Dog Food – Considered for Grain-free

The grain-free blend from Nutrisca is a cost-effective way to give your dog more fiber. The salmon is the star, despite the fact that it’s significantly less costly than a complete meal. 

While we love the nutritional benefits of salmon, some of our dogs got nasty fish breath, so we preferred the Nutro Natural Choice Dry Dog Food – For Dogs Aged 1+.

 4. Fromm Gold Coast Grain-Free Dog Food – Considered for Dry formula

At Fromm Gold Coast, grain-free meals start with whitefish and salmon, which are also produced without wheat.

This food helps you regulate your dog’s weight while still providing him with the nutrition he needs. Get a 4-pound sample bag if you’re not sure whether your dog will like the food. 

Our dogs weren’t fans of the food, so we didn’t push them to test it beyond the 4-pound bag. They definitely preferred the Wellness CORE Dry Dog Food.

 5. Royal Canin Fiber Response Dog Food – Considered for Gastrointestinal response formula

Thanks to Royal Canin, we can get high-quality high-fiber dog food, though it must be prescribed by a veterinarian.

We got that prescription for our dogs with severe anal gland issues and gave this food a try.

The results were mixed. We were happy with what we saw in our dogs’ stools, but our dogs weren’t totally thrilled with the flavor of the kibble.  

It works well for many dogs, and we have friends who love their Royal Canin. However, it didn’t place in our top 5 because it needs a prescription so it’s a bit hard to get.

Instead, we chose to recommend Instinct Raw Boost Dog Food which is also high fiber and can be purchased in-store or online.
