High-fiber diets are now known for their nutritional advantages when used in combination with a healthy lifestyle. This applies to our dog’s diet as well. However, before you make the choice to increase your pup’s fiber intake, talk to your veterinarian and do research on what is an appropriate food for your specific dog, as some dogs suffer from food allergies and may require grain-free puppy food or similar instead. Therefore, try to understand why extra fiber a is plus, what it is, and how it works. If your dog is suffering from the following, then talk to their veterinarian and start assessing what changes need to be made in your dog’s diet.

  • Constipation
  • Diarrhea
  • Poor blood sugar levels (diabetes)
  • Difficulty with weight loss (obesity)
  • Gland problems
  • Hemorrhoids

What Is Fiber?

Fiber is a part of carbohydrates that are not easily digestible in the dog’s body. It resists enzymatic digestion in the small intestine. Fiber is plant-based material that is often found in the cell walls of grains and plants that the body doesn’t process in the diet. This crude fiber is called roughage which helps with bowel movements, can aid weight loss, and help improve a dog’s health—especially diabetic dogs. There are 2 types of fiber: soluble and insoluble. Soluble fiber is what it sounds like. It absorbs water. It breaks down into mucus-like material at different rates depending on the fiber. This material ferments and passes through the colon while releasing gases for digestion. In contrast, insoluble fiber absorbs much less water and won’t ferment. Too much of fast fermenting fiber can cause issues so it’s important to choose a high-fiber dog food that won’t negatively affect your pup’s digestive system.

What Should You Look for in a High-Fiber Dog Food?

There are some great high-fiber dog foods available but there are also others that you won’t want to feed your dog. High-fiber dog foods that list cellulose in their ingredients means there is the potential that they may use shredded paper as a filler. Reading nutrition labels on pet food to look for specific sources of dietary fiber and talking to your veterinarian can help pick the best food for your dog. Standard dog food has 2–4% fiber, whereas a high fiber one will be 6–10% and a source of vitamin and protein-rich ingredients. Dogs need their change to a new high-fiber food to be gradual and monitored. A quick change from low fiber to high fiber can trigger colitis, which is inflammation of the colon. This can mean too much defecation, diarrhea, and loss of nutrients. It can also lead to weight gain as your pet ends up hungrier. So, with a quality, new high-fiber dog food, moderation is the best way to go. Remember, when assessing a new food:

  • Dogs need different fiber than humans. Human fiber isn’t dog fiber. Humans can eat corn and grain. Dogs should not due to their short digestive tract.
  • Test new dog food in small amounts. Don’t purchase too much in case your pet reacts badly physically or taste wise.
  • Your pup’s system needs adjustment time so change foods gradually.
  • Choose nutrition over cost. Expensive is not always best and cheap isn’t either. Read the nutritional labels and get advice from your veterinarian.

What Food Should You Choose?


Many dog foods claim they are full of protein and high fiber so it is wise to not only look at the ingredient list but extra benefits a food may offer. You can often find one that is natural, high fiber, and beneficial to other health issues your dog may have. Look for the following:

  • Whole protein is their first ingredient on the nutrient list. Dogs need fruits, vegetables, and whole grains but also proteins that come from meat.
  • Avoid foods with vaguely described products that simply say by-products and meat meal. These two items are actually beneficial to your dog but should be listed as a single item. Make sure they are descriptive such as “pork by-product” rather than simply meat by-product.
  • Avoid foods with artificial color or flavors as they can trigger allergies.
  • Look for omega-3 fatty acids for anti-inflammatory help as well as antioxidants.
