Purchasing the Best High Fiber Dog Foods for Constipation

Why Eat Fiber-Rich Food?

You may be asking why a high fiber meal is a suitable choice if your dog is constipated. This is due to the fact that fiber, both insoluble and soluble, can assist control gastrointestinal motion. Insoluble fiber passes through the digestive tract and adds weight to the stool, which helps to relieve constipation (or loose stools), although both types are beneficial in foods. Fiber can also help with:

  • Assist your dog in losing or maintaining weight.
  • Enhance blood sugar stability
  • Lower your risk of colon cancer

All of these are fantastic reasons to switch your dog to a higher fiber diet!

What to Look for in a Fiber-Rich Dog Food

If you’re not sure what to look for in high-fiber dog diets, have a look at the list below!


The first thing you should check for in a dog food is how much fiber it contains (obviously). This is classified as “crude fiber.” Fiber levels in dog food vary greatly. Many dog feeds include only 1-2%, whilst others have 10% or more.

Most dogs only require 2-4% fiber in their meals, but if your dog is constipated, they may require a bit more. We recommend contacting with your veterinarian to determine how much your dog should be receiving.

Additional Ingredients

You’ll also want to look at the elements in a dog food that aren’t fiber-containing. Your dog will require a lot of protein, so look at the amount and quality of the food.

Real meat as the initial component is always preferred, however meat by-products and meat by-product meals are also acceptable.

Aside from the protein source, you’ll want to be sure the remainder of the contents are healthy and beneficial to your pet.

Legumes and peas

Peas and beans are two ingredients to avoid in dog food. Though much more study is needed, there have been some correlations between them and canine heart disease. When purchasing dog food for your dog, you’ll need to decide how you feel about these substances (especially since many higher fiber dog foods contain these ingredients).


If you’re not cautious, dog food may quickly become prohibitively expensive. It is beneficial to shop around for the greatest discounts by looking for more than one cuisine that includes the elements you want.


Reviews from other dog owners are an excellent method to determine how wonderful a dog food is and how effectively it treats constipation. These assessments are frequently more truthful than branding and marketing promises.
