When you’re choosing the most appropriate dog food for Rover, you should focus on giving him a complete and balanced diet.

As well as ensuring that protein, carbs, and fats are all present in the right proportions, you should also make certain your dog is getting enough fiber on board.

Why is this?

Well, fiber delivers valuable nutrients to the bacteria and cells in your dog’s colon. Fiber also helps to stop some toxins from absorbing into the bloodstream.

Finding the best high-fiber dog food that your dog will wolf down can be tough, though.

If your dog is a picky eater, he might not find all high-fiber dog food to his liking.

With a bit of patience, you should find a food that’s rich in fiber that your dog will relish. We review ten of these for you today, so you’re spoiled for choice.

By providing your pooch with the right amount of fiber, you’ll be delivering the following benefits:

  • Lowers the risk of colon cancer
  • Regulates Rover’s bowel movements
  • Helps prevent constipation
  • Strengthens his immune system
  • Reduces risk of infections
  • Supports weight management
  • Stops canine bloating

Fiber can also help to improve diabetes, according to the AKC (American Kennel Club).

Not all fiber is created equal, though, so it pays to be aware of what kind works best for dog’s whole body health.

You should always look closely at the labels on any dog foods you’re considering. Ideally, look for food that’s high in insoluble fiber. This type of fiber can relieve constipation, reduce bloating, and regulate bowel movements in your dog. Most vet’s prescription diets for dogs will have elevated levels of insoluble fiber.

Even if you’re brand new to dog ownership, you’ll already be aware that dogs love eating. If they eat food that’s laden with insoluble fiber, this expands their digestive systems. Resultantly, they will feel fuller more rapidly. This helps prevent overeating and obesity. By eating fiber-rich food, dogs will also feel fuller for longer.

There are many sources of insoluble fiber you could introduce into your furball’s diet, including:

  • Pumpkin
  • Beet pulp
  • Ground flaxseed
  • Apples
  • Dark leafy greens
  • Brown rice
  • Carrots

Beyond adding these foods to your dog’s diet, you could also consider any of the formulas on our shortlist, all ideal for dogs requiring a high-fiber diet. is reader-supported. When you buy via the links on our site, we may earn an affiliate commission at no cost to you.

1) Why does my dog need dietary fiber in the first place?

Food with the right amount of fiber can help your dog in many ways. Not only does feeding your dog a fiber-rich diet improve his overall colon health, but you’ll also be minimizing his chances of developing colon cancer. High-fiber dog food can also be beneficial for weight management purposes. Fiber goes some way toward stabilizing blood sugar levels in diabetic dogs. Fiber also serves to help control constipation and diarrhea.

2) How does fiber play a role in canine weight management and weight loss?

By feeding your dog high-fiber foods, it will increase the bulk in his diet. He’ll feel fuller for longer without adding calories.

3) What are the best foods I can give my dog if I want to increase the amount of fiber he’s consuming?

Firstly, consider a high-fiber dog food like the ones on our list today. That way, you won’t need to worry about sourcing ingredients as the formula already contains ample fiber. Brown rice, oats, pumpkin seeds, flaxseed, vegetables like carrots and beet pulp, and apples all contain plenty if dietary fiber.

4) What’s the difference between soluble fiber and insoluble fiber?

Fiber, then, is the element of plant-based foods that pass through your dog’s digestive system without being broken down or digested. Soluble fiber (gums, plant pectins) dissolves in water. Insoluble fiber (plant cellulose, hemicellulose) doesn’t dissolve in water. Broadly speaking, soluble fiber can help to improve digestion. This type of form can also reduce blood sugar levels, making it potentially useful as a component of managing diabetes. Insoluble fiber, by contrast, will attract water into your dog’s stools. This softens the stools and makes it easier for your dog to poop. This type of fiber also promotes bowel health and keeps your pooch regular.

5) What happens if I feed my dog a diet containing too much fiber?

Too much fiber in your dog’s diet can trigger bloating and gas, so avoid this.

6) How does fiber in dog food help to manage diarrhea?

Fiber in dog food absorbs moisture. At the same time, it has gelling and binding properties that mean high-fiber foods are worth introducing if your pup is suffering from a nasty bout of diarrhea.

7) I heard that fiber is not considered an essential nutrient.

This is technically correct, but the vast bulk of commercial dog food contains fiber, as it’s certainly beneficial, even if it’s not termed essential. Don’t sell your furball short here.

8) How is it possible for fiber to reduce my dog’s risk of developing colon cancer?

The way in which fiber accelerates elimination means your dog’s exposure to carcinogens will be limited. As an unbuilt bonus, the fiber should also alleviate diarrhea and constipation symptoms.

9) How is fiber believed to help with managing diabetes?

Fiber slows down digestion in your dog. This alone may help prevent blood sugar levels from suddenly spiking. Some research also suggests that fiber can sometimes reduce sensitivity to insulin in dogs. The reason for this is not yet fully understood.

10) If I want to change my dog to a high-fiber dog food, how should I do this?

Make the change gradually over the course of a ten-day period. Begin by introducing 25% new food with 75% of his old food. Stick with this ratio for a few days to get him accustomed to the new food. Start mixing 50% old food and 50% new food for a few days. Add even more of his new food until, after ten days, he’s wolfing down all-new high-fiber dog food.


We hope today’s showcase of the best high-fiber dog foods has given you plenty of options for switching up Rover’s diet.

Whenever you’re changing your dog’s food, you should do so gradually over the course of ten days. Start by mixing 25% new food with 75% of his old food. Then, increase the ratio so he’s eating a 50/50 mix of old and new food. Push the new food up to 75% of his total ration, and then move on to all-new food after ten days.

We would always advise starting off with a small bag of food until you’re sure it makes a good fit for Fido.
