Dietary fibers for dogs are recommended for healthy gut flora, solid stools, and an overall well-kept digestive system. This article answers all common questions about crude fibers, soluble and insoluble fibers for dogs, as well as prebiotics. We have also reviewed the top 5 best fiber-rich dog foods and the top 5 best fiber supplements for dogs.
What Are Fibers in a Dog’s Diet?
Dietary fibers in dogs, also commonly referred to as roughage, are the indigestible aspects of plant matter that assists in the bodily function known as intestinal peristalsis. In other words, it’s a type of carbohydrate found in foods that pass through a dog’s digestive process but is not digestible. Furthermore, it has the ability to absorb water. Fiber for dogs can come in one of two components: soluble and insoluble fiber.
Soluble fiber is soluble in water, that is, it dissolves in water. It also tends to ferment easier in the colon to later turn into gases and is the type of fiber that passes through the digestive tract with more ease. These fibers also form viscous or gelatinous substances. Dogs who suffer from bacterial overgrowth will benefit from soluble fiber as it helps produce short-chain fatty acids from the fermentation, which provide energy. On the other hand, insoluble fiber does not dissolve in water and its key proponent is used to provide bulk in the digestive tract and does not ferment, which makes it metabolically inert.
Dietary fiber is able to literally change how nutrients are absorbed and passed in the body. Dog food labels provide information regarding how much crude fiber it contains. Crude basically refers to the method in which the product was tested and how much of that particular content is found in the food. In technical terms, it’s the indigestible contents of cellulose, lignin, and pentosans measured as a quantitative number. It has nothing to do with the actual quality of the food itself. In this case, the crude fiber is taken from the food to determine the amount of fiber level which is then used to determine crude protein. Most dog foods that you buy contain about 5% crude fiber. Any food that is above 5% is considered “high fiber food”.
What Are Fibers Good For?
A diet rich in high fiber for dogs contains a number of benefits that range from a healthy colon to bulking activity, as well as assist in weight management. As the fiber passes through the body, the bacteria in the intestines break it down. Fiber assists in the defecation process and prevents hemorrhoids by facilitating the natural emptying of the anus. In addition, some vets even say that fiber-rich foods help prevent colon cancer in dogs. Aside from regulating the intestines and aids in maintaining the healthy gut flora, fibers also slow down the absorption of glucose levels in the blood. Lower glucose levels mean less insulin activity which may lead to serious health complications down the road.
Fibers as a weight management aid help your dog feel full for longer periods of time, thus keeping it from over-eating. This also reduces the chances of developing obesity and therefore, diabetes as well. In addition to weight management and keeping your dog fit, fiber plays a crucial role in your dog’s immune health by reducing inflammations and therefore, reduces the risk of cardiovascular diseases. It also increases the growth or sustainability of beneficial bacteria in the gut. Though keep in mind, dogs who suffer from chronic diarrhea should not take too much fiber as it may worsen their symptoms or it may be an indication of an underlying problem.
How Much Fiber Do Dogs Need?
An average-sized dog’s typical diet consists of roughly 2.5% to 4.5% fiber. More than 5% crude fiber for a normal dog is sufficient as long as it’s not too much. Larger dogs may need more due to their size. Small dogs only need 1 TB of fiber serving as opposed to bigger dogs. Additionally, dogs who suffer health ailments, such as those which are gastrointestinal related, may need a specified amount. In this case, professional opinion from the vet is recommended.
When beginning to introduce fiber-rich foods for dogs, slow and steady is the key. You don’t want to run the risk of giving too much at one time. Generally, you can tell if your dog is getting sufficient fiber in his diet by examining how he or she is doing. If he is active, defecating regularly, is growing and is at an ideal weight for his age then chances are he’s getting enough. Conversely, if he’s having digestive issues and weight problems then you may need to increase the fiber.
Some vets recommend whether the source is from vegetables, pumpkin, or psyllium husk powder, a teaspoon for every 10lbs of body weight is enough once or twice a day. For mashed sweet potatoes, you can use 1-3 tablespoons.
What Are the Dangers Associated with Fiber-Rich Diets in Dogs?
An overabundant amount of fiber in the diet can lead to upset stomach, gas, bloating, and also abdominal discomfort and pain. Dogs, on average, should have two bowel movements a day.
Although it’s common knowledge that high fiber for dogs provides an array of benefits and health advantages, too little or too much is not ideal. In fact, giving too much fiber to your dogs can result in adverse reactions. Excessive fiber can cause dogs to defecate very often causing many minerals and nutrients to not be properly digested and absorbed. Due to excessive defecation and fewer nutrients, your dog may counter this issue by eating more than is recommended which can ultimately lead to weight gain. Moreover, too much fiber can lead to a condition known as colitis, which is an inflamed colon. Colitis can cause your dog to strain during defecation and may excrete blood or mucus in the stool.
What Is a Good Source of Fiber for Dogs?
In regards to finding a good source of fiber for dogs, it’s always recommended to choose whole options, as in, whole fruits and vegetables. Most carbohydrate sources contain a decent amount of fiber. When choosing carb sources, aim for the higher fiber content as opposed to refined grain sources as they will provide many calories but too little nutrition. Some common sources of fiber include beet pulp, peanut hulls, rice hulls, bran, and pectin. In addition to these, you will find quite a bit of commercialized dog food products that get their fiber sources from flaxseed, whole grains, carrots, oats, apples, and legumes.
Other fiber-rich dog foods include sweet potato and pumpkin which are excellent sources of fiber for your dog and are considered superfoods. You can scoop up some of the pulp of each and add it to your dog’s dinner for a real boost. Other common sources that dog owners tend to lean on are high-fiber dog treats and fiber tablets. In the case of fiber tablets, they are usually only necessary in severe cases. You can also get a generous source of fiber from green foods such as green beans.
How Can I Add Fiber to My Dog’s Diet?
To incorporate more fiber into your dog’s diet you may want to switch up your dog food brands to a higher fibrous content kibble. For dog owners who don’t want to make the transition, there are fiber capsules and similar prebiotic supplements on the market, but adding fibrous foods is usually recommended and more natural.
As previously mentioned, you can begin by adding small portions of pumpkin pulp or puree, roughly 1 tablespoon per 20lbs of weight. Sweet potatoes and green beans can be microwaved or blended into their dog food. Bran cereal works wonders for your dog. You can add pieces of these high-fiber bits into the food or serve them separately as snacks. Just make sure they are not filled with added sugars.
Moreover, you can incorporate more fiber-rich dog supplements into your dog’s diet by way of buying more fibrous vegetables. These veggies can be steamed in a way that makes it easier to chew and be given throughout the day as nutritious snacks. Likewise, a source of fiber for puppies can be any of these items mentioned but mashed to a softened texture. Lastly, add some prebiotics to your dog’s diet. These can be bought as supplements, generally bundled with dog probiotics. If unsure, ask your vet for some recommendations.
Do Fiber-Rich Foods for Dogs Help with Diarrhea?
For dogs who have stomach problems and frequent diarrhea, fiber-rich dog food or just plain sources of fiber can aid them greatly. For example, insoluble fiber works as a bulking agent in stools and absorbs the water in the intestinal tract which, in turn, produces harder fecal matter.
Soluble fiber helps provide more friendly bacteria in the gut through the fermentation process while it assists in balancing the acid levels. Additionally, soluble fiber delays gastric emptying, thus better controlling the flow. However, too much fiber is counterproductive because it will actually speed up the digestion transit which is what you don’t want. Moderation is key.
Importance of Fiber for Dogs with Exocrine Pancreatic Insufficiency
Dietary fiber plays a very crucial role for dogs who suffer from Exocrine Pancreatic Insufficiency (EPI). This disorder prohibits the break down of food and restricts the body’s ability to utilize the important nutrients. To treat this, dogs are advised to take soluble fibers as well as undergo an enzyme replacement therapy. Only soluble fiber will work for this since fiber naturally is not a great aid for pancreatic enzymes, but the soluble kind is easily digestible. These specialized meals will have to be fed to your dog several times a day for optimum efficiency.
