10 Best High Fiber Dog Foods of 2021 – Reviews & Top Picks

Earthborn HolisticA high fiber diet is often advised for . In some cases, this type of diet might be recommended by a veterinarian, especially if your dog suffers from constipation or diarrhea, after eating.

Specialty high fiber dog foods usually contain anywhere from 4% to 12% fiber levels. For an average-sized dog, weighing approximately 50 pounds, this is the equivalent of feeding 12 cups of pumpkin in a single day. These foods really are high in fiber.

Most of these foods are available without a prescription. They increase the size and weight of your dog’s stool, making it easier to pass and helping to prevent constipation. Fiber also absorbs water, so it solidifies watery diarrhea, therefore hardening your dog’s stools.

With plenty of choice on the market, it makes choosing the right brand and the right food difficult. To help, we have studied some of the most popular foods and compiled a list of reviews of the best foods.

  • The 10 Best High Fiber Dog Foods – Reviews 2021

    1. Royal Canin Gastrointestinal High Fiber Dog Food – Best Overall

    Royal Canin Veterinary Diet Gastrointestinal High Fiber Dry Dog Food

    Royal Canin Gastrointestinal High Fiber Dry Dog Food is a dry kibble consisting of chicken by-product meal, brown rice, and brewer’s rice as its primary ingredients. Chicken by-product meal is not the most appealing of ingredients, being made from food processing leftovers, but it does have a high protein concentration.

    It also contains corn and other corn derivatives. It has slightly lower than average protein and higher than average carbs. It has 3.6% fiber content, which is not the highest, but this Royal Canin high fiber food is well-loved by owners and dogs alike, is suitable for dogs of all sizes and breeds, but it is on the pricey side. Despite the cost, however, if your veterinarian has advised you to feed a high fiber food, this makes an excellent choice of dry kibble.

    • Omega-3 oils derived from fish oil
    • Antioxidants help maintain immune system
    • Includes prebiotics for good gut bacteria
    • Slightly pricey

    2. Rachael Ray Nutrish Dry Dog Food – Best Value

    Rachael Ray Nutrish Little Bites Small Breed Natural Real Chicken & Veggies Recipe Dry Dog Food

    With primary ingredients of chicken and chicken meal, Rachael Ray Nutrish Little Bites Small Breed Dry Dog Food is packed with carbohydrates to give your small breed dog extra energy. It also includes omega oils that will keep your dog’s coat healthy and shiny. Cranberries help your dog control stress, and the formulation is rich in peas, beets, and carrots, which give the recipe approximately 4.5% fiber concentration.

    The ingredients do include alfalfa, which is included for its high fiber levels, but it is more commonly associated with horse feed than dog food. Unfortunately, the food does contain artificial coloring, iron oxide. This gives the food a red color, which obviously isn’t for the benefit of the dog but to appeal to owners. Another reason that this food has been kept from the top spot is that it does not include any probiotics, which are used to coat high-quality food and make it easier for your dog to digest the kibble.

    The food is well balanced, with average levels of protein, carbohydrates, and fat, and it is very well priced, being the cheapest food, per pound, in our list of reviews. This makes it the best high fiber dog food for the money.

    • Cheap
    • Well balanced kibble
    • Includes omega oils
    • 5% fiber
    • Includes artificial coloring
    • No probiotics

    3. Blue Buffalo Life Protection Dog Food – Best for Puppies

    Blue Buffalo Life Protection Formula Small Breed Puppy Chicken & Oatmeal Recipe Dry Dog Food

    Blue Buffalo’s Life Protection Formula Dry Dog Food has a good 5.6% fiber content, and its primary ingredients are chicken, chicken meal, brown rice, barley, and oatmeal. You will also find flaxseed, which is a good source of omega-3 and soluble fiber.

    Alfalfa meal is included in the food, which helps boost the fiber level, but is a common ingredient in horse feed.

    The formula does not include any artificial colorings, which is a positive, but it does contain garlic. Garlic is considered a somewhat controversial ingredient in dog food. Although there are some claimed benefits to the ingredient, it is toxic in large quantities and there are many critics that believe it is still damaging even in smaller amounts. Dried yeast is another controversial item found in this food, although unless your dog is specifically allergic to it, it should be fine in the volumes found in the food.

    The Blue Buffalo formula has average protein and fat levels, as well as carbohydrates, and is considered the best brand for puppies because of its small kibble and the inclusion of a probiotic coating that will help your puppy digest the food more easily.

    • 6% fiber
    • Flaxseed oil provides omega-3
    • No artificial colorings
    • Small kibble is suitable for puppies
    • Includes garlic and dried yeast
    • Protein could be higher for puppies

    4. Wellness CORE Grain-Free Dry Dog Food

    Wellness CORE Grain-Free Ocean Whitefish, Herring & Salmon Recipe Dry Dog Food

    The CORE Grain-Free Dry Dog Food from Wellness comes in a variety of flavors, including an ocean whitefish, herring, and salmon recipe. The poultry-free recipe has higher than average protein levels and lower than average carbs.

    Wellness CORE Grain-Free Dry Dog Food has 7% fiber thanks to the inclusion of ingredients like pea and tomato pomace. There is also flaxseed, which not only adds soluble fiber to the mix but also omega-3 oil. One of the benefits of the Wellness CORE mix is that it is a grain-free recipe. Some pets suffer from allergies or may be intolerant to grains. This can lead to itching, flaky skin, and other symptoms including gastric distress. If you have eliminated other potential causes of these allergy symptoms, it could be the grain in your dog’s food that is causing them discomfort.

    CORE is an expensive food, but it gets a lot of its nutritional ingredients from high-quality meat protein sources, in particular from whitefish, herring, and salmon, in this recipe, and does not rely on the addition of excessive amounts of vegetable or fillers. It is also happily lacking in controversial ingredients, with only tomato pomace and pea fiber considered slightly controversial because they are deemed to only have moderate nutritional benefits.

    • High meat protein content
    • Does not contain meat by-products or filler
    • Added vitamins and minerals provide further benefit
    • Grain-free recipe
    • Expensive
    • Not all owners want a grain-free recipe

    5. American Journey Healthy Grain-Free Dog Food

    American Journey Healthy Weight Chicken & Sweet Potato Recipe Grain-Free Dry Dog Food

    American Journey Healthy Weight Grain-Free Dry Dog Food is another grain-free recipe, this time combining chicken and sweet potato as its primary ingredients. It has approximately 5.5% fiber content and is considered to have higher than average protein content as well as below-average fat and carbs.

    This is another high-quality, premium food, that contains no truly controversial ingredients. It does include plain beet pulp and pea protein, both of which are scorned for their minimal nutritional value, but they are non-harmful and non-toxic. Beet pulp is only considered controversial because it is considered a filler, but it is high in fiber, hence its addition in this food. Pea protein is also considered a filler, but it is high in concentrated proteins so it does have nutritional benefits.

    Among other beneficial additives, American Journey has included taurine, which is an amino acid that encourages the healthy function of the heart muscle. This has been included because, although taurine is not an essential mineral for dogs, it has been shown to be lacking in dogs on a grain-free diet. With this being a grain-free food, its inclusion is considered beneficial.

    • Grain-free good for grain insensitivity
    • No filler or by-products
    • Added taurine
    • 6% fiber
    • Expensive
    • Grain-free isn’t best for all dogs

    6. Natural Balance Fat Dogs Low Calorie Dog Food

    Natural Balance Fat Dogs Chicken & Salmon Formula Low Calorie Dry Dog Food

    Natural Balance Fat Dogs Low Calorie Dry Dog Food is high in fiber, with approximately 11.5% fiber content, and is geared towards overweight dogs that need to shed pounds.

    As such, Natural Balance has very low-fat content, which is achieved through the use of ingredients such as beet pulp, pea fiber, alfalfa meal, and dried tomato pomace. In a lot of cases, these ingredients would be considered moderate to low quality because of their low nutritional benefit. But when they are used to reduce calories, they provide a beneficial source of protein and fiber.

    The primary ingredients are chicken meal and salmon meal. These are considered forms of meat concentrate and have much higher concentrations of protein than standard meat. This recipe is also high in garbanzo beans, which are also referred to as chickpeas. These are high in protein, although vegetable protein is not considered as beneficial or as high quality as meat protein.

    Natural Balance does contain brewer’s yeast, so you should avoid this food if your dog is known to have an allergy to this particular ingredient. Also, while there are no studies to back this up, there is a growing number of people who claim that brewer’s yeast increases the likelihood of dogs developing bloat.

    • Low levels of fat
    • 5% fiber content
    • Primary ingredients are chicken, salmon, and garbanzo beans
    • Pricey
    • Only really suitable for overweight dogs

    7. Taste of the Wild Grain-Free Dry Dog Food

    Taste of the Wild High Prairie Grain-Free Dry Dog Food

    Taste of the Wild High Prairie Grain-Free Dry Dog Food uses buffalo as its main ingredient and has around 4% fiber content, which is about average for this type of high fiber food. It has average protein and fat levels, although these could still be higher to benefit most dogs.

    The formula is grain-free, but there is a long list of ingredients that mean this food is unlikely to be suitable for those dogs that do suffer from food allergies. However, it does include fresh vegetables and fruit, while the beef, venison, and other meat ingredients encourage strong and robust muscle growth. There are no artificial additives or preservatives.

    Your dog will also benefit from the probiotics that improve digestion and make it easier for them to benefit from the nutritional ingredients. Added vitamins include omega-3 and omega-6, although there are foods with a more optimal level of omega-6. This food may not have enough protein for highly active dogs but should be more than sufficient for less active canines.

    There are no ingredients that are considered unsafe for canine consumption, and only the pea protein and potato protein are considered low quality, which makes this a premium quality food, despite the long list of ingredients.

    • No grains
    • Plenty of meaty ingredients for protein
    • No harmful ingredients
    • Not ideal balance for active dogs
    • Omega-3 concentration could be higher

    8. Blue Buffalo Wilderness Grain-Free Dog Food

    Blue Buffalo Wilderness Chicken Recipe Grain-Free Dry Dog Food

    Blue Buffalo claims to use a recipe that harks back to the days when wild dogs would have thrived on a diet that was rich in meat protein and free from ingredients like grain. Many food manufacturers include ingredients such as corn because they are cheap and help to increase protein and other nutrient levels. In reality, however, protein derived from these sources is not as good quality or as beneficial for your dog as meat protein. Some dogs can also be sensitive to grain ingredients, which can lead to itchy skin, excessive scratching, and gastrointestinal complaints.

    The Blue Buffalo Wilderness Grain-Free Dry Dog Food formula has 6% fiber and, thanks to the inclusion of fish meal and flaxseed, among other ingredients, it also offers decent levels of omega-3 and omega-6. It does contain yeast, which is another potential irritant, but unless your dog is allergic to this particular ingredient, it should be considered perfectly safe in the levels included.

    • Grain-free recipe
    • 6% fiber
    • Omega-3 and omega-6 oils
    • Primary ingredient is real chicken
    • On the expensive side

    9. Earthborn Holistic Meadow Grain-Free Dog Food

    Earthborn Holistic Meadow Feast Grain-Free Natural Dry Dog Food

    With a 4.4% fiber ratio, Earthborn Holistic Meadow Feast Grain-Free Dry Dog Food has a moderate level of fiber. Its primary ingredient is bison meal, which is a concentrated form of bison with a high protein level. It also has a high concentration of peas, which helps provide natural fiber.

    Another major ingredient is canola oil. Canola oil is considered a controversial additive because it is derived from GM rapeseed. With that said, it is a good source of omega-3, although not as biologically available as essential oils from fish.

    The food is considered to derive a lot of its protein from good quality meat ingredients, but the existence of canola oil, coupled with the pea protein and pea fiber that are found in this formula are not good quality, especially considering the premium price tag attached to this particular food.

    • Decent level of meat content
    • Grain-free formula
    • Includes canola oil
    • Includes pea protein and pea fiber
    • Expensive

    10. Blue Buffalo Basics Diet Dry Dog Food

    Blue Buffalo Basics Limited Ingredient Diet Turkey & Potato Recipe Small Breed Adult Dry Dog Food

    Blue Buffalo is known for producing some high quality, premium foods, including grain-free and high fiber foods. The Basics line has less of a premium price tag. One way in which Blue Buffalo has kept the price tag down by using a recipe that is high in carbs. Carbs are a cheap way of filling a dog up, but they do not provide the nutritional value that your dog needs.

    This food is considered to have a higher than average carb rating. It does have a 6.7% fiber concentration, which is considered above average, although its fat content is not that low for a food labeled diet.

    The Blue Buffalo Basics Limited Ingredient Diet Dry Dog Food also contains canola oil, which is derived from GM rapeseed and does not provide the same omega-3 concentration as good quality fish oil. Dried yeast is also found in this food, and as well as being a potential allergen, there are a number of owners that claim it increases the likelihood of dogs contracting bloat.

    • Fairly cheap
    • Slightly lower than average fat
    • Fat ratio isn’t as low as other diet foods
    • Contains canola oil
    • Contains yeast
    • Utilizes fillers like alfalfa meal
