Why Dogs Need Fiber

dog food bowl with spoon of fiber

Canines need fiber in their diets to help keep the digestive tract functioning, but that is not the only area in which fiber adds health benefits. A high-fiber diet can help dogs lose weight, lower sugar levels, and reduce the risk of colon cancer. It helps with constipation, loose stools, and diarrhea. Fiber is not found in animal meats or proteins. It must come from plant materials like fruits and vegetables.

Fiber, a carbohydrate, comes in two forms, soluble and insoluble.

  • Soluble fiber attracts water and turns gel-like in the process, which slows down digestion. Soluble fibers work to help reduce cholesterol and blood sugar, reducing the risk of diabetes.
  • Insoluble fiber helps food pass through the digestive tract and adds bulk to a dog’s stool. Insoluble fiber also brings water into the stool, which helps it soften and pass easier.

When To Consider A High Fiber Dog Food

There are several reasons your pup may need a higher-fiber diet. If they are struggling with constipation or are putting on weight, this food can help. Older canines often become less active and may start to experience more digestive upset. Because they do not move as much, they do not burn off as many calories, leading to weight gain. A higher-carb formula keeps them feeling full, for a longer stretch of time, without taking in extra calories.

Dogs who have diabetes may benefit from a higher-fiber food as it slows digestion and keeps sugar levels lower. Fewer spikes and dips in blood sugar help stabilize diabetic canines. Fibers reduce the sensitivity canines have to insulin as well. While not suitable for every diabetic pup, the diet is beneficial for some pups. Always discuss changes with your vet first.

Canines who suffer from anal gland irritation and malfunction may benefit from a more fibrous diet. The carbs can help them poop, which helps the anal glands to release.

Remember that too many fibrous proteins can be a problem, so do not overdo it. Discuss changing your pup’s diet with your vet. Make the change gradually rather than all at once. Changing foods too often or rapidly can cause dogs to develop stomach upset and irritation, Including pooping blood.

Personal Experience With American Journey

“Our dog Barley was suffering from anal gland issues, so we did an elimination diet and found he was allergic to poultry. When I was looking for poultry-free dog food for Barley, I also focused on higher fiber to further support anal gland health. So, we landed on this food which is fish-based and also 6% fiber (a little higher than avgerage). Since switching to the American Journey food 6 months ago, Barley has had zero anal gland issues.”

How To Add Fiber To A Dog’s Diet

Switching to or mixing in a high fiber dog food or other highly fibrous foods to their diet is an easy and effective way to raise the fiber intake. If you are not ready to switch your dog to a higher fiber formula, plenty of fresh fruits and vegetables can be added to the bowl or used as snacks. There are several natural, very healthy sources. These include beet pulp, pumpkin, ground flaxseed, lettuce, kelp, carrots, green beans, apples, brown rice, and berries like strawberries and blueberries.

Good Sources Of Fiber For Dogs

Pumpkin is one of the best sources of fiber owners can choose to give their dogs. Other high-quality sources include broccoli, microgreens, leafy greens, and grains. Other highly fibrous foods include squash, sweet potatoes, oats, barley, and quinoa, to name a few. If you add fresh vegetables or fruit to your pup’s diet, use plain, fresh produce. It is particularly important not to feed your pet foods prepared for humans or other animals. It may contain ingredients like garlic, onion, or added sweeteners and sugars that are unhealthy or even toxic for canines to eat.

How To Change Your Dog’s Food

It is not ideal to switch your dog’s food too quickly. The change should be a gradual process. Regardless of what food you are switching to, slowly mix the new food with the old, and gradually increase the amount of the new food until your dog is no longer eating any of the older varieties. It can take several days, even up to two weeks or more, to fully transition over. It is essential to take the process slowly, as switching too quickly can cause digestive upset, stomach pain, and even straining to poop or blood in a dog’s feces.

Not Sure High Fiber Is Right For Your Pup?

High-fiber dog food isn’t right for every pup. If you are still determining if higher fiber is the right direction for your sweet pup, there are plenty of other options to consider. Owners can look for low-carb dog food, human-grade, as well as dog food formulas for overweight and obese dogs, diabetic formulas, freeze-dried foods, and many more. It is best to evaluate your dog’s health situation and know what you are looking for in order to make the best dietary decisions for your pet. Always discuss changing a dog’s diet, especially if your dog has any medical conditions or special needs, with your veterinarian or pet nutritionist first.
