  • Digestion Aid: This is the most common advantage to a high fiber diet and the one that everyone is aware of. Fiber offers the regulation of digestion function through a variety of functions – it can draw water into the intestine if your dog is constipated or draw water from the intestine if your canine has diarrhea. It also provides additional ‘bulk’ to your dog’s poop, ensuring smooth digestive function.
  • Improved Blood Sugar Levels: This is also linked to the next two points – blood sugar levels are important for both weight and canine diabetes. Adding proper amounts of fiber into your dog’s diet ensures their blood sugar stays within a healthy and consistent range, which helps fight obesity and avoid a diabetes diagnosis. The same applies to humans as well!
  • Weight Management: With obesity being a recognized problem with many domesticated dogs, ensuring your furry friend stays within a healthy weight range is very important. Fiber is a great addition to your dog’s diet as it takes up room in their stomach and isn’t digested, meaning it stays in their system for longer periods. This ensures they won’t feel hungry, allowing them to feel full without adding calories.
  • Reduce the chance of diabetes: Fiber is suggested to be consumed by humans that are at a high risk of developing diabetes, and the same approach applies to dogs. As diabetes causes the malfunctioning of the pancreas, this means that insufficient amounts of insulin are created by the body. Insulin regulates blood sugar levels and, when there isn’t enough, blood sugar levels don’t act as they should. Fiber can keep blood sugar levels where they should be by slowing down the rate that sugar is absorbed by a dog’s body. Some studies have shown that if a dog consumes regular amounts of fiber, their susceptibility to diabetes can decrease quite a lot.
  • Alleviate clogged anal glands: It isn’t the most appealing topic, but fiber can help with your dog’s anal glands. Small dogs especially can be affected by blocked anal glands, however, fiber can assist by changing your dog’s stool. As fiber changes the consistency of stools to firm and bulky, this assists with allowing the release of the anal glands naturally due to pressure caused when they go to the bathroom. Clogged anal glands can cause your canine friend a lot of discomfort, so helping with this is a huge benefit!

Best Sources (Ingredients) for Fiber

  • Carrots: A common choice when it comes to ingredients full of fiber is carrots – not only are they a high fiber and low-calorie vegetable, they are also packed with vitamins K, A, and B6 (which help with eyesight). They are a great choice as they offer more than just fiber, including positively benefiting heart health and helping with digestive issues.
  • Apples: Apples are another low calorie, high fiber option for your furry friend. They are full of vitamins and have great overall health benefits for all types of dog breeds. Always remember to remove the core though, as apple seeds in large amounts can be quite toxic to dogs!
  • Flaxseed: When you see flaxseed as an addition in dog food, it is usually milled (not whole). This is because when it is whole, its’ tough outer shell makes its fiber insoluble. Once it is milled, and the outer shell is removed, it becomes soluble dietary fiber. Flaxseed joins with different things, such as fat, cholesterol, and bile, which ensures your dog’s digestive system stays in top condition and they have continuing digestive health.
  • Pumpkin: Another vegetable choice is some canned or steamed pumpkin – pumpkin isn’t just high in fiber, it is also low in calories and high in potassium. And, if you choose the canned variety, there is also an added level of ease when adding it to your dog’s daily meal.

There are also oats, psyllium husk, barley, peaches, tomatoes… the list goes on!

How much Fiber is Considered “High Fiber”?

Generally, dog food has a fiber content of 1-10%, with anything above the 5% level being considered high fiber. If food has over 10% fiber content, this can negatively affect stool volume and firmness, which is not beneficial.

  • Does my dog need more fiber? – Although a traditional ‘wild’ canine diet contains very little fiber in it, as a dog does not have any physiologic need for it, it has been shown that dogs who eat processed dog foods that contain fiber do benefit from it. It assists with digestion and some fibers contain vitamins and minerals, which offer great benefits all-round.
  • Are carrots good fiber for dogs? – Yes, they are! Carrots are a low calorie, high-fiber snack for your dog. They also contain antioxidants and vitamin A, which are great for maintaining overall health and wellbeing.
  • Is potato high in fiber? – It depends on the potato you are referring to, as sweet potatoes are great sources of fiber however other types of potatoes don’t offer the same fiber levels. Additionally, there have been warnings from the FDA regarding possible connections between food containing potatoes and canine dilated cardiomyopathy (DCM), therefore potatoes may not be an appropriate addition to a dog’s diet. And never feed your dog raw potatoes!
