Basics of High Fiber in Your Dog’s Diet

Fiber is actually a part of edible plants that cannot be digested, or at least resists digestion. Fiber cannot be found in any animal based products, only in plants. It is made up of several compounds, all of which are carbohydrates. Usually fiber is characterized in two ways, solubility and fermentability. Insoluble fiber cannot be dissolved in water, and instead absorbs it. As such, as it works through the digestive tract, fiber helps promote regular bowel movements and clears the tract.

One major contribution is that fiber affects how quickly food passes through the digestive system. It is the ultimate regulator! In cases of diarrhea it will slow things down. In cases of constipation it works to speed things up. This is why fiber has such a normalizing effect on digestion. In turn, a healthy digestive system will also improve your pet’s immune system. It will also help them maintain a healthy weight and prevent bloating, constipation, and diarrhea.

Fiber in Dog Food

Fiber is not usually considered an essential nutrient in a well balanced diet for your dog. Dogs cannot derive any energy from it and it is not a big part of their ancestral diet. Despite this though, fiber is still included in almost every commercial dog food. This is because a high fiber dog food will help improve your dog’s digestive health. It can also help improve conditions like diabetes, chronic constipation, and diarrhea.

Perhaps the leading reason many dog owners put their dogs on a high fiber dog food is to help them maintain a healthy weight.

Your pet’s nutritional requirements for fiber will depend on their age, breed, activity levels, and overall well being. If you have questions about fiber in your dog’s diet you should consult with a veterinarian. Find out the amount of fiber your pet needs and start feeding your dog something to help instead of hinder their digestive health. Most manufacturers will use vegetables and whole grains, for both nutritional value and as a source of fiber. But, some use less quality sources like peanut shells or grain hulls.

Ideal Fiber Content in your Dog Food

Look at the Guaranteed Analysis section of your dog food label. This will tell you how much of each nutrient is in the food. Usually your dog’s diet should include anywhere from 1% to 10% fiber. Moderate levels of fiber are usually around 2% to 4%. High fiber dog foods are usually in the 5% to 10% range. In amounts more than 10 percent, the food may actually be detrimental to your pet unless recommended by your vet. Unfortunately, the Guaranteed Analysis does not tell you the whole story. It says nothing about the quality of fiber.

For that information you turn to the listed ingredients. Usually the top five ingredients make up the majority of your dog’s dry dog food. There you will find the highest sources of fiber. You will also be able to determine if they are quality ingredients for your pet, or whether they are causing gastrointestinal problems.

Not Any Fiber Will Do

If rapidly fermented fiber sources are used in excess, your dog might have negative reactions to the food. What you need to do is check out the fiber sources. Not all fiber sources will be good for your dog, especially if they have allergies or sensitivities to certain grains or ingredients. In fact, fiber sources like corn, soy, wheat, and rice most often cause allergic reactions in dogs. You will need to find the best dog food brand that is rich in fiber, but also suits the individual needs of your pet.
