Fiber for Dogs Guide

The benefits of fiber in dog food are vast. Not only does fiber help to regulate blood sugar levels, but it also helps to keep your dog regular and can even help prevent some diseases. In order to determine the best fiber in dog food for your pet, you need to understand what fiber is and what benefits it provides.

What is fiber?

Fiber is a type of carbohydrate that the body cannot digest. There are two types of fiber – soluble and insoluble. Soluble fiber dissolves in water and helps to form a gel-like substance in the gut, which slows down digestion. This is important for blood sugar control as it helps to regulate the release of sugar into the bloodstream. Insoluble fiber does not dissolve in water and helps to add bulk to the stool, which keeps the digestive system regular.

Fiber can also be defined in two ways; by solubility and by fermentability. Fiber solubility is determined by how well the fiber dissolves in water. Fermentability is determined by how quickly the bacteria in the gut ferment the fiber. Different types of fibers have different solubility and fermentability levels, which is why it’s important to understand both when determining the best type of fiber for your dog.

High-Fiber label on pet food products may be misleading:

AAFCO requires pet food manufacturers to indicate the maximum percentage of fiber when listing ingredients on dog food labels. This requirement to have the guaranteed analysis disclosing only the maximum crude fiber can be misleading as it does not give the consumer an accurate representation of the true fiber content in the food. A more accurate way to determine the fiber content would be for pet food companies to list the minimum percentage of crude fiber. This would give dog owners a better idea of how much actual fiber is in the food.

For example, a dog food brand with a maximum of 10% crude fiber has no more than 10 grams of crude fiber for every 100 grams of total dog food. However, this food could actually have as little as 1% crude fiber, which would be much lower in actual fiber content.

Many pet food companies choose to list the maximum percentage of crude fiber because it is less expensive to add fillers and other indigestible ingredients that increase the crude fiber content without adding any nutritional value. These ingredients are often referred to as “fiber fillers” and can include things like cellulose, hemp, and flax.

What experts say about high-fiber diets in dog food labels:

In this report by Deborah E. Linder of Cummings School of Veterinary Medicine at Tufts University, she further argues that crude fiber labels only account for a variable portion of insoluble fiber and do not give an accurate representation of the total dietary fiber.

Below is a table showing the crude fiber listing on AAFCO’s table recommendation of the maximum amounts that pet food manufacturers should include;

Dietary fiber is made up of both soluble and insoluble fibers. The most common type of insoluble fiber in dog food is cellulose, which is plant-based. Cellulose is not digestible by dogs or humans, so it does not provide any nutritional value. Other types of insoluble fibers include hemicellulose and lignin.

Soluble fibers are fermentable by the bacteria in the gut and can be broken down into short-chain fatty acids (SCFAs). These SCFAs are used for energy by the body and have been shown to have health benefits, such as reducing inflammation, improving gut health, and aiding in weight loss.

The most common type of soluble fiber in dog food is pectin, which is found in fruits and vegetables. Other types of soluble fibers include gums, mucilage, and fructans.

4 Main Benefits of Fiber for Dogs:

As a dog owner, it is important to understand the benefits of fiber and how to add it to your pet’s diet. Some of the benefits of fiber include:

Fiber helps in Blood sugar control:

As mentioned above, soluble fiber helps to regulate blood sugar levels by slowing down digestion and the release of sugar into the bloodstream. This is especially important for dogs with diabetes as it can help to prevent spikes in blood sugar levels.

Fiber helps Digestive health and prevents constipation:

Fiber is important for digestive health as it helps to add bulk to the stool and keeps the digestive system regular. This is important for dogs who suffer from constipation or diarrhea as fiber can help to alleviate these symptoms.

Fiber can help to prevent some terminal diseases:

Some studies have shown that fiber can help to reduce the risk of certain diseases such as obesity, heart disease, and cancer. This is due to the fact that fiber helps to regulate blood sugar levels and cholesterol levels, which can lead to these diseases.

Fiber assists with weight loss:

Fiber is important for weight loss as it helps to regulate hunger levels. This is because fiber takes longer to digest, which means that you feel fuller for longer after eating. This is especially important for dogs who are overweight or obese as fiber can help them to lose weight in a healthy way.

How to Recognize the Symptoms of Diabetes in Your Dog and What You Should Do If You Suspect It

If your dog is urinating more frequently, drinking more water, and/or losing weight despite having a good appetite, these could be signs of diabetes. If you suspect that your dog has diabetes, it is important to take them to the vet for a check-up as soon as possible. Early diagnosis and treatment are essential for managing this condition.

The water-holding fiber in the intestine acts as a barrier, slowing nutrient absorption. Fiber also slows the emptying of the stomach, which is why your pet would be feeling fuller after eating high-fiber foods. This delayed emptying can help regulate blood sugar levels by preventing spikes after meals.

There are two types of fiber: soluble and insoluble.

Soluble Fiber:

Soluble fiber dissolves in water and forms a gel-like substance in the intestine, which slows down digestion. This is important for blood sugar control as it helps to regulate the release of sugar into the bloodstream. Good sources of soluble fiber include oats, barley, and legumes.

Insoluble fiber:

Insoluble fiber does not dissolve in water and helps to add bulk to the stool. This is important for preventing constipation as it helps to keep the digestive system regular. Good sources of insoluble fiber include wheat bran and vegetables.

When choosing a dog food, it is important to look for one that contains both soluble and insoluble fiber. This will ensure that your pet is getting the best possible nutrition and the most benefits from their food.

The best way to add fiber to your dog’s diet is to choose a food that is high in fiber. You can also add some cooked vegetables or oats to their regular food. If you are adding fiber to your dog’s diet for the first time, it is important to do so slowly to avoid any digestive problems.

High-fiber Dog Food Recipes:

There are hundreds of dog food recipes that are high in fiber. Some pet food manufacturers include fiber in pet food to increase the bulk and to compensate for adding little of other ingredients such as proteins and fat. It is important to check the label on the food to make sure that it does not contain too much fiber as this can lead to health problems.

8 Best Sources of Fiber in dog food diet:

There are many sources of fiber that you can add to your dog’s diet. Some of the best sources of fiber include:

Rice:

White rice is a good choice for dogs recovering from a stomach upset since it is bland and easy to digest. Plain chicken and white rice are available in small amounts and are readily absorbed.

Brown rice are also great options for dogs but they are not as easily digestible as white rice. In fact, brown rice are great for humans.

Rice contains these nutrients:

Pumpkin:

Pumpkin is a great source of soluble fiber, which makes it ideal for blood sugar control. It is also a low-calorie food, which makes it perfect for dogs who are trying to lose weight.

Pumpkin also contains these nutrients:

Vitamin A

Potassium

Copper

Manganese

Potatoes:

Sweet potatoes are another great source of soluble fiber, making them ideal for blood sugar control. They are also a good source of vitamins and minerals, including potassium and magnesium. Sweet potatoes can be given cooked or raw and make a great addition to any dog’s diet.

On a Dry-matter basis, raw potato fiber is 88.4% while cooked potato fiber is 90.2% as shown in the chart below showing the chemical composition of raw and cooked potato fiber.

4 Signs/Symptoms of fiber deficiency in pet food diet:

There are a few signs and symptoms to look out for that may indicate your dog is not getting enough fiber in their diet. These include:

  • Diarrhea: Diarrhea is the most common symptom of fiber deficiency in dogs. If your dog is having loose stools or watery diarrhea, it may be a sign that they are not getting enough fiber in their diet.
  • Weight loss: If your dog is losing weight, it may be a sign that they are not getting enough calories or nutrients in their diet. Fiber helps to add bulk to the food and can help dogs feel fuller longer.
  • Constipation: If your dog is constipated, it may be a sign that they are not getting enough fiber in their diet. Fiber helps to add bulk to the stool and can help to keep things moving along smoothly.
  • Hunger: If your dog is always hungry, it may be a sign that they are not getting enough fiber in their diet. Fiber helps to add bulk to the food and can help dogs feel fuller longer.

Prebiotics and probiotics: What’s the difference?

Prebiotics are a type of soluble fiber that is not digested by the body but fermented by the bacteria in the gut. Unlike probiotics that are not fiber, prebiotics is a type of soluble fiber or fermentable carbohydrates also called oligosaccharides in the gut.

Probiotics are live bacteria and yeasts that are good for your health, especially your digestive system. They help to restore the natural balance of microbes in the gut when it’s been disrupted by an illness or change in diet.

Both prebiotics and probiotics are important for gut health, but they have different roles. Probiotics help to restore the balance of good and bad bacteria in the gut, while prebiotics help to feed the good bacteria.

Wet vs Dry High-fiber dog food:

There are two main types of high-fiber dog food: wet and dry. Wet food typically has a higher moisture content than dry food, which can be beneficial for dogs who are prone to constipation.

Dry food typically has a lower moisture content and is a good option for dogs who are trying to lose weight. High-fiber dog food is also available in both kibble and canned forms.

The best way to determine which type of food is best for your dog is to talk to your veterinarian. They can help you choose a food that meets your dog’s individual needs.

Fiber content in wet dog food is generally higher:

Canned dog food typically has a higher moisture content than dry food, which can be beneficial for dogs who are prone to constipation. The fiber content in canned dog food is also generally higher than that of dry food.

11 Health Conditions for Which Fiber May Assist in Nutritional Management.

Below are 11 health conditions that may be alleviated by a high-fiber dog diet;

  1. Anal gland or sac disease: Fiber may help to bulk up the stool and make it easier to pass, which can help to reduce the inflammation and irritation associated with anal gland disease. If your dog has anal gland issues, we have reviewed the most ideal diet here.
  2. Dental disease: The abrasive action of fiber can help to remove plaque and tartar from the teeth, which can help to reduce the risk of dental disease.
  3. Diabetes: Fiber can help to regulate blood sugar levels and may help to prevent or delay the onset of diabetes.
  4. Gastrointestinal issues: Fiber can help to bulk up the stool and make it easier to pass, which can help to reduce the inflammation and irritation associated with gastrointestinal issues.
  5. Weight management: Fiber can help to keep dogs feeling full longer, which can help with weight management

Estimating Dietary Fiber in Dog Food:

Looking at the fiber content in most commercial dog food available on the market, the average dry dog food contains 2.5 and 4.5 percent crude fiber. In low-calorie diets, it may even be higher – up to 10% as per Dog Food Advisor’s guide on fiber.

In the table below, you can see that the guaranteed analysis of max crude fiber for Diet A is 11.3% and 10% for Diet B. The 1.3% difference may appear close but true comparison reveals that Diet A had double the amount of fiber as Diet B.

t1701c06table02

How is that?

Diet B has 4.6g/Mcal of insoluble fiber while Diet A has 27.9 g/Mcal. In other words, Diet A has 6 times more insoluble fiber than Diet B. Diet B has 22.4 g/Mcal of soluble fiber and Diet A has 27 g/Mcal of soluble fiber, a smaller difference but overall, the total fiber for diet A is 54.9 g/Mcal while Diet B has 25.1 g/Mcal.

It is important to understand the make-up of fiber content in any dog food brand and specifically understanding;

  1. The % guaranteed analysis of crude fiber
  2. The rough estimates of soluble and insoluble fiber in grams per Megacalorie.

Fiber Supplementation:

There is limited info on the recommended dose of fiber to give dogs as supplemental fiber. A 2000 Study on the treatment of chronic idiopathic large-bowel diarrhea in dogs with a highly digestible diet and soluble fiber, Lieb found human supplements to be effective.

In the study, Lieb Ms. recommended that dogs get a median daily dose of 2 tablespoons of a popular human psyllium supplement. He also highlighted that a range was 0.75 to 6 teaspoons could be effective depending on the health condition of the dog needing fiber supplements.

Read the whole study here.

Fecal Scoring and determining the right fiber:

Whether your dog is on dietary fiber supplements or not, it is important to monitor their fecal matter. You need to watch out for the changes in fecal appearance, texture, and how much is being passed. This will help you and your veterinarian adjust the amount of fiber needed for your dog.

There are several ways to score a dog’s stool but for simplicity, we will use the chart below by Purina. You can also check out this one by University of Missouri.

Type 1: Hard, dry stool that is difficult to pass. May be accompanied by and pellets

Helpful tip: Add moisture to the diet with canned food, broth, or water.

Type 2: Firm but not hard, pliable and segmented in appearance. Does no residue on the ground when picked up.

Helpful tip: Increase the amount of dietary fiber.

Type 3: Log-shaped, moist surface. Little or no segmentation and leaves resident on the ground when picked up.

Helpful tip: no specific changes need to be made.

Type 4: Soft surface with a mucous coat. Sausage-shaped and may contain undigested food.

Helpful tip: Add fiber to the diet gradually as this may indicate an intolerance.

Type 5: Very moist, but has a distinct shape. It may be present in piles rather than log.

Helpful tip: tip: Add fiber to the diet gradually as this may indicate an intolerance.

Type 6 & 7 : Unformed, liquid stool that may be accompanied by straining.

Helpful tip: This is an emergency and you should seek veterinary care immediately as your dog may be dehydrated.

Helpful tips when transitioning to a High-fiber dog diet:

When starting or transitioning to a high-fiber diet, it is important to know the following;

  • Increase fiber gradually over 7–10 days. This will help your dog’s digestive system adjust to the change and avoid potential gastrointestinal upset. Gut bacteria takes time to adapt
  • Insoluble fiber adds bulk to the stool, make sure your dog has access to plenty of fresh water to prevent dehydration.
  • Increase exercise gradually as well. This will help your dog’s digestive system adjust to the change and avoid potential gastrointestinal upset.
  • Monitor your dog’s stools closely for any changes in consistency, frequency, or volume.
  • Loose stool is expected during the transition and shouldn’t worry you.
