What is High-Fiber Dog Food?

High-fiber dog food is a healthy formulation for your dog’s diet containing a high proportion of dietary fibers.

High-fiber dog food should contain high-quality plant-derived fiber sources such as peas, whole beans, spinach, and more. A high concentration of such whole foods can boost the digestive ability of dogs and maintain their overall immune system.

Do Dogs Need High-Fiber Food?

Yes, high-fiber dog food is necessary. The general idea is that carnivores like dogs only need high protein content in their food.

However, this idea can be misleading. High-fiber content is essential for dogs to flush out toxins from their gut, consistent stool, and better digestion. Without a healthy gut and digestive system, no amount of nutritious food will have any positive results for your dog.

Is a High-Fiber Diet Good for Dogs?

Yes, high-fiber dog food is good.

Using high-fiber diets comes with several health benefits. Here is a closer look at them:

  • Consistent Poop Texture. Fiber-rich food supports consistent stool texture. Therefore, it is good for both dogs with diarrhea and dogs with constipation.
  • Regular Bowel Movements. Dietary fibers keep the dog’s intestines running smoothly and on a regular basis. This helps prevent constipation and anal gland problems.
  • Improved Digestion. This is the most pronounced benefit of a high-fiber diet. Prebiotics aid in digestion and prevents unwanted bloating in dogs.
  • Healthy Weight Control. High-fiber foods help with weight management as they are rich in dietary fiber – fiber helps add bulk to the food and keep the dog satiated for longer. Prebiotics also support weight loss by keeping the dog‘s bowel movements regular.
  • Strong Immune System. A high-fiber dog food ensures that the toxins inside a dog’s gut are flushed out regularly. It is also rich in antioxidants which strengthen immunity.
  • Diabetes Mellitus Management. A high-fiber food is good for managing diabetes mellitus. Prebiotics help reduce blood sugar levels and prevent sudden spikes.

How do I Know if a Dog Food is High-Fiber?

Make sure to check for the following factors to determine whether a pet food is high-fiber or not:

  • Overall Fiber Content. High-fiber dog food usually has around 6% crude dietary fiber.
  • Insoluble vs. Soluble Fibers. Both soluble and insoluble fibers are necessary as they have different roles: soluble fibers reduce blood sugar levels, whereas insoluble fibers enhance stool texture. Thus, good high-fiber food must have both types of fibers for overall health.
  • High-Quality Fiber Sources. The sources of fiber must be high-quality. Otherwise, no matter the concentration, there will be no health benefits.

What Should I Look for in a High-Fiber Dog Food?

When looking for premium quality high-fiber dog food, you need to consider features like natural ingredients, balanced formula, and flavor preference. In addition to these factors, it is useful to opt for a recipe featuring one or more of these high-fiber fruits & veggies:

  • Beetroot: Beet pulp has one of the highest-fiber sources amongst natural ingredients – 11-19% per cup.
  • Carrots: Contain 2.8 grams of fiber on average and improve liver and kidney function.
  • Pumpkin: A flavorful superfood with 7.1 grams of dietary fiber per cup
  • Ground Flaxseed: Features 2 grams of fiber per tablespoon. They are also a great source of omega-3 fatty acids that improve skin and coat health in dogs.
  • Berries: The most indulgent source of natural fibers. Blueberries and strawberries contain at least 3 grams of dietary fiber in each cup.

How Much High-Fiber Dog Food Should I Feed My Dog?

As a rule of thumb, each serving of your high-fiber food should have 6-10% crude fiber.

This works for most breeds of dogs in adult life stages. It is best to keep it at 6% for your puppy or a small breed dog. Anything below this content will not serve the purpose of a high-fiber diet and might lead to digestive issues. Make sure your pet has at least 10gm of fiber in each meal.

But it is important to follow the manufacturer’s feeding instructions as they may vary depending on the formulation and brand.

Are There Any Drawbacks to a High-Fiber Diet for Dogs?

A high-fiber dog food has a few drawbacks if it is not balanced.

Diarrhea, bloating, and gastritis are common issues when dogs have too much fiber in their diet. There have been cases of hard stools and weight gain issues due to excessive fiber intake. It is thus important to consult a veterinarian to understand the correct amount of fiber your dog needs.
