Fiber refers to a group of substances grouped with carbohydrates. Unlike starches, fibers are resistant to digestion in the small intestine. As a result, fibers are fermented by bacteria in your colon. Fiber helps keep your dog's digestive system functioning correctly.

In the wild, fur is a natural component of a canid’s diet. Wild dogs eat the fur of their prey, such as rabbits, rodents, or other small mammals. Fur is a beneficial source of fiber for dogs that aids in the digestion of food, allowing it to pass through the digestive system more efficiently—this aids in preventing constipation in dogs and reduces the risk of bloat.  

Other benefits of fur consumption include maintaining blood sugar levels, a source of vitamin B12, which aids in cognitive ability, and a source of manganese, which aids joint and ligament health. Bacillus spp., a common bacteria within the gut microbiome, produces keratinase, an enzyme that degrades keratin. The minor keratin degradation allows minimal extraction of the fur’s vitamin and mineral content, making them available to your dog. 

Although fur is found in kibble as whole animals are processed in the rendering plant, it does not have the same benefits as natural fur due to the high heat processing of the rendered materials. 

IIncreasing the bulk and water content of the digestive contents is the primary purpose and benefit of consuming enough dietary fiber.

In dogs with normal or slow intestinal transit times, fiber seems to shorten it; in dogs with quick intestinal transit times, fiber lengthens it. Together, these elements encourage and control healthy bowel movements.

Acetate, propionate, and butyrate, the typical byproducts of microbial fiber fermentation, are extremely important for your dog's colon health. By producing short-chain fatty acids, fiber increases the amount of anaerobic flora and decreases luminal pH.

The antibacterial properties of short-chain fatty acids may reduce pathogenic (disease-causing) intestinal bacteria, increase gut resistance to pathogenic bacterial colonization, and aid in the prevention and treatment of intestinal illnesses and cancer. Prebiotic dietary fibers also encourage the development of beneficial bacteria that guard the GI tract against disease invasion.

Prebiotic fibers may also improve immune function by modifying gut-associated immune cells via their carbohydrate residues and decreasing fecal odor by altering fecal metabolite concentrations.

It has been discovered that fiber is essential to colonocytes to maintain the health and proper operation of the entire GI tract.

Diabetes, obesity, gallstones, hypercholesterolemia, IBS, constipation, colonic diverticulosis, colorectal cancer, celiac disease, Crohn's disease, migraine headaches in children, and dental cavities in adults have all been treated with dietary fiber.

Changes in bacterial flora that occur during pregnancy and aging may affect health and disease resistance. The prevalence of potential infections like Clostridium perfringens is increased in older dogs.

Different types and amounts of dietary fiber may play a part in treating particular medical diseases in dogs and cats.

Since it absorbs water in diarrhea and adds moisture to constipation, fiber controls the amount of water in the intestines. By controlling the water content of the stool, more fermentable fibers (such as gums and soy fibers) can help dogs with diarrhea and constipation by making a watery stool drier and a dry stool moister.

With the higher digestible viscosity associated with slower transit and delayed stomach emptying, fiber's binding and gelling properties aid in controlling diarrhea. Dogs with constipation benefit from fermentable fibers' increased weight and moisture content in the stool.

ave been associated with allergies, diarrhea, and inflammatory bowel disease. In this case, prebiotic fibers can assist in restoring or maintaining a healthy balance of beneficial bacteria while also inhibiting the growth of dangerous organisms and their role in the development of disease.

It's also important to remember that dogs fed raw have smaller poops and are known to experience fewer issues with their anal glands. Poops that are more consistent and harder express the anal glands naturally, enabling them to work correctly.

Recommended sources of fiber include psyllium husk, larch, and slippery elm. The dosage for dried psyllium husk is based on feeding fiber at 5% of your dog’s meal.

Because it is a dried product, you multiply the required amount of fiber by 0.2 to account for the lack of moisture in the psyllium husk. You can then convert the amount to teaspoons (tsp) using the calculation of 6 teaspoons in a dry ounce. As per the calculations, the following would be given: 

Add ¼ teaspoon for every 10 pounds of dog. Watch your dog’s stool to determine if the amount needs to be adjusted. 

Slippery elm should be given with food. Placing it in warm water will result in a gelatinous product that can be combined with other foods. The dosage is: 

Small dogs: ¼ teaspoon three times a day

Medium dogs: ½ to ⅔ teaspoon three times a day

Large dogs: ¾ to 1 teaspoon three times a day

The management of diabetes mellitus in humans, dogs, and cats includes dietary changes. The glycemic index is a system for rating carbohydrates based on how carbohydrates affect blood sugar levels.

Both slowly and quickly fermentable fiber types help to lower blood glucose levels in diabetic animals.

Changing the source of carbohydrates or adding fiber can impact a food's glycemic index. Clinical studies have demonstrated that feeding dogs foods containing cellulose, soybean hulls, or peanut hulls can minimize or even eliminate the need for an insulin prescription. Sorghum and barley were also shown to produce lower insulinogenic responses in dogs and cats than in rice.

Fiber is broken down enzymatically by intestinal microorganisms such as bacteria, fungi, and protozoa but not by intrinsic mucosal digestive enzymes. These microorganisms present in the lower small and large intestines are known as anaerobes or facultative anaerobes because they can survive without oxygen. They can live by converting food into energy through fermentation.

The bacteria that inhabit the lower gastrointestinal system are similar to those that inhabit the rumen in ungulates like cows. The type of fermentable substrate influences the availability of various bacterial species. Different substrates support different microorganisms. As end products, different combinations of substrates and microbes result in various amounts of short-chain fatty acids and methane.

Although fiber is regularly included in commercial foods, it is not considered necessary for a dog's diet. Dogs do not get much energy from the typical end products of bacterial fermentation, but short-chain fatty acids are crucial for colon health.

However, it is already a standard component of commercial dog food and raw feeding models like the Real Ancestral Diet.

Providing a small amount of fiber (5 percent) that contains both quickly and slowly fermentable fibers in meals for healthy pets is recommended. The efficacy of "pharmacologic dosages" of specific nutrients (fiber) in preventing chronic diseases is currently a hot topic in human and veterinary nutrition.

Obesity, diabetes, colitis, diarrhea, and constipation are a few other conditions that can benefit from adding fiber to the diet. Dogs who don't get enough fiber frequently experience loose stools or diarrhea, blocked anal glands, excessive appetite, and low energy.

If your dog is currently eating kibble, you can add fiber by topping off her dish with any of the following:

Flaxseed: High in dietary fiber and antioxidants and can improve intestinal health in your dog.

Apples: High in fiber while low in calories; also great for dental health.

Carrots: High in fiber; also beneficial to the liver and kidneys.

Green beans: Low in calories and high in fiber.

Broccoli: Easy-to-digest fiber source that contains vitamins and trace elements.

Fur and feathers: Fur and feathers are an excellent source of fiber and manganese.

There’s likely fiber in your dog’s commercial kibble from beet pulp, but this is where examining your dog’s poop comes in. If your dog’s poop is frequently runny or doesn’t seem to have a firm consistency, adding a source of fiber to its dish is recommended. 

Make sure to include a range of fiber sources in your dog's diet, whether you're home cooking or feeding them raw food. An easy way to provide adequate levels of fiber is to feed dogs whole prey with fur or feathers intact. Procuring whole unprocessed animals can be challenging. However, many commercial products in an air- or freeze-dried form meet these fiber requirements. 

The treats at Real Dog Box  also provide sources of fiber as the rabbit feet, cow ears, boar ears, and other treats still contain their fur and feathers. 

Psyllium husk can provide a source of fiber and bulk up your dog's stools, whether home cooking, raw feeding, or giving them a commercial diet. Psyllium expands and gives intestinal contents greater solidity when combined with water, encouraging your dog's body (or your own) to move the contents through, resulting in a firmer stool.

Fruits and vegetables are also excellent fiber sources. The next lesson covers the importance of fruits and vegetables in the dog's raw bowl.

Fiber can be insoluble or soluble, but both benefit our dog's (and our own) health.

The primary purpose and benefit of sufficient dietary fiber are improving and maintaining the digestive system.

  Providing whole-food sources with the fur and feathers still intact increases fiber in the diet, resulting in a healthier dog.
