This is our review of the best low carb dog food in 2021
Dogs are omnivores with digestive systems optimized to thrive on high protein animal products.
Although carbohydrates can provide your active pup with usable energy, fats are usually the primary energy source in canine diets.
When dog foods have excess simple carbohydrates, these ingredients can contribute to weight gain and high blood sugar levels.

But every pup is different. So I researched the best low carb formulas in every category to help you make the best decision for your furry best friend.

- Caloric Content: 412 kcal/cup
- Type of Product: Grain-Free, Gluten-Free, No Corn, No Wheat, No Soy, High-Protein
- Life Stage: Adult
- Best For: Low Carb Dog Food for Small Breeds
Most small breed dog foods use high levels of refined carbohydrates to meet the high-calorie needs of toy breeds. But not all small dogs do well on a high-carb diet.
So this dog food features alternative sources of complex carbohydrates and a high protein content instead.
Turkey is the primary source of the high 36% protein content. All dogs, no matter how small, need high levels of quality protein in their diets.
This higher protein content combines with a high 16% fat content to ensure that this food meets your tiny friend’s daily caloric requirements.
Lentils and peas act as alternative sources of complex carbohydrates to ensure small breeds still get adequate glycogen from a low 33% carbohydrate recipe. Dogs with smaller muscle mass can’t store significant amounts of glycogen and are susceptible to hypoglycemia. 
Additional protein from turkey and chicken meal offer natural sources of glucosamine and chondroitin. These chondroprotective ingredients are essential for protecting the weak joints of tiny legs.
Small breeds also often have difficulty chewing and swallowing the kibble of most average dog food formulas. Reviews from parents of tiny pets highly recommend the small shape and size of this kibble exclusively designed for little mouths.

- Type of Product: Grain-Free, No Corn, No Wheat, No Soy

- Best For: Low Carb Dog Food for Large Breeds
Large breeds have relatively slower metabolisms than their smaller cousins. They are also more predisposed to issues associated with obesity due to their already large body mass. This grain-free dog food helps manage their health risks with a lower carbohydrate content.
The 27% protein content from chicken is ideal for gentle giants. Chicken is a lean meat that offers high-quality animal protein without extra calories or fat. The lower 12% fat content also helps limit the caloric content of this recipe to 365 kcal/cup.
Although the 47% carbohydrate content is higher than others on this list, it consists primarily of complex carbohydrates. Starchy vegetables like peas and sweet potatoes are lower in calories than alternative refined carbohydrates from grains.
Excluding grain-based products and other common causes of food intolerances also helps manage larger pups’ sensitive systems.
Giant breeds often experience a higher risk of bloat or gastric upset. Lower carb diets can help reduce the inflammatory response.
The alternative sources of carbohydrates included in this recipe are also rich in fiber. Fiber does not provide extra energy, but it is a valuable prebiotic that helps support the good bacteria in the gut responsible for breaking food down and reducing bloat risks. 
Owners of gentle giants recommend this dog food for pups with digestive issues and often notice improvements in stool frequency and consistency.
- First 5 Ingredients: Chicken, Chicken Meal, Sweet Potatoes, Pea Fiber, Potatoes

Weight control is the most common reason dog owners choose to transition their dogs to a low carb diet. This weight management formula limits carbohydrates and fats to control the caloric content of this dog food.
The moderate 26% protein content of this food is ideal for dogs on weight control diets. Chicken provides adequate levels of amino acids without drastically increasing the caloric amounts. Higher levels of protein could also be too much for dogs with sedentary lifestyles.
An exceptionally low 6.5% fat content is essential for dogs who need to lose weight. Your dog needs fat for energy but will store it as excess pounds when he does not use it.
This crude percentage works together with the lower 47.5% carbohydrate content to manage weight gain.
Despite the low-fat content, ocean fish meal ensures that your dog still gets the healthy omega fatty acids he needs. These fats are especially vital for overweight dogs as they help reduce inflammation in stressed joints. 
The recipe is also free from grains, gluten, wheat, corn, and soy. These ingredients can irritate the digestive systems of sensitive pups. And unlike some low-fat formulas, most dog owner reviews recommend the natural flavor for picky pets.

This grain-free limited ingredient diet features a base of only eight whole foods that provide balanced nutrition while eliminating common allergens. The low carbohydrate content also helps prevent inflammation in sensitive digestive systems. 
Salmon is the single source of the high 32% protein content in this dog food. Single source proteins are vital for limited ingredient formulas because they limit exposure to other proteins that may cause allergic reactions.
This fish is an ideal animal protein for sensitive dogs because of its high levels of healthy fats. The high 18% crude fat content contains significant amounts of omega-3 fatty acids. This fat helps boost immune function and reduce inflammation.
There are no fillers included in this recipe. Artificial flavors, colors, and preservatives often trigger adverse reactions in sensitive dogs. The formula is also chicken-free and excludes any grains that may cause a gluten allergy.
Fortification with Canidae’s proprietary blend of antioxidants, probiotics, and chelated minerals allows this simple recipe to meet your dog’s daily nutritional needs. Dog owners often report improvements in skin health on this diet.
Low Carbohydrate Dog Food Buying Guide
Although carbohydrates can be a safe component of a healthy canine diet, some pups need low carb dog foods to thrive due to health concerns.
What are Carbohydrates?
Carbohydrates are one of the three main macronutrients that your dog’s body uses to obtain energy.
Sugars, starches, and fiber from grains, fruits, and vegetables are all carbohydrates. These sugars are easily digested but may contribute to excessive weight gain in some dogs.
Do Dogs Need Carbohydrates?
Dogs are omnivores who depend primarily on protein and fat from their diet. They do not need significant amounts of carbohydrates to stay healthy.
Dog foods with higher levels of carbohydrates may damage your pup’s metabolism and contribute to GI inflammation.
Although fats and protein are easier to digest, carbohydrates appear in canine diets for extra energy.
Very active dogs or toy breeds with fast metabolisms may benefit from consistent dietary carbohydrates. But high-fat ingredients can also supply adequate power.
Benefits of Low Carb Diet
The primary benefits of low carb dog food relate to feeding your dog a diet that he can digest efficiently based on his evolution. Reducing carbohydrate content can also help overweight dogs lose fat by reducing excessive calories in their daily meals.
Diabetic dogs often require low carbohydrate diets to prevent dangerous blood sugar spikes. And the higher protein content of some low carb formulas may help meet the extra amino acids necessary for healing processes in unhealthy pups.
Excessive carbohydrates can also contribute to inflammation in the digestive tract. Low carb diets can help offer relief and soothe their bowels. Plus, carbohydrates can trigger some allergic reactions. Low carb dog food can help manage these reactions in sensitive dogs.
Additional benefits of managing your dog’s weight with low carb dog food include reducing the risk of heart and kidney issues associated with canine obesity.
What to Look for When Buying Low Carb Dog Food
Not all carbohydrates are created equal. And without carbohydrate content explicitly included on the dog food label, it can be challenging to determine the best low carb diet for your dog.
Simple vs. Complex Carbs
Even low carb dog foods will generally contain some sources of carbohydrates. The healthiest carbohydrates for dogs are complex carbohydrates found in whole grains and grain-alternatives.
Simple carbohydrates from refined grains are high in sugar but low in fiber and nutrients. Whole grains include the fibrous parts of the plant that are generally richer in vitamins and minerals.
Dogs who require a low carb diet generally do best on grain-free formulas that use starchy vegetables as alternative sources of complex carbohydrates. These ingredients take longer to break down and will not cause sharp blood sugar spikes.
If a dog food contains less carbs, the recipe generally has to make up for the lost energy with a higher protein content.
Protein is the most critical macronutrient in any canine diet, providing the amino acids necessary for growth and body functions.
Dogs have digestive systems designed for real meat. Look for a formula that uses animal protein instead of plant protein. Real meat should always be the first ingredient, as animal protein is much more bioavailable to dogs than plant protein.
Although carbohydrates can be an excellent source of digestible energy, fat is the primary energy source of canine diets. Dogs can quickly use the calories from fat to support a healthy metabolism and active lifestyle.
Omega fatty acids can further promote overall well-being in your dog by supporting a healthy skin, coat, and immune system. These healthy fats have anti-inflammatory effects and can help stimulate natural skin oil production.
Vitamins and Minerals
Every canine diet needs a balanced amount of vitamins and minerals. These nutrients are critical for ensuring your pup stays happy and healthy.
The best bioavailable sources of vitamins and minerals in low carb dog food are whole fruits and vegetables.
How to Calculate Carbs in Dog Food
The label of most dog foods does not contain the carbohydrate content of the formula. Instead, you can use the guaranteed analysis of your dog food to calculate the estimated carbohydrate content yourself.
Simply add together the total moisture, protein, fiber, and fat content of the food before subtracting the result from 100. The remaining percentage represents the estimated total carbohydrate content in the dog food.
Feeding your dog a low carb diet can help manage the health conditions associated with canine obesity.
Carbohydrates can be an excellent source of quickly digestible energy for active dogs. But excessive amounts of carbs can cause unwanted weight gain and contribute to the risks associated with high blood sugar in sedentary pups.
Dogs thrive on high protein diets that use fats as the primary source of energy. They do not necessarily need the high levels of carbohydrates frequently found in commercial dog foods today.
I recommend Blue Buffalo Wilderness Grain-Free Dog Food as the best low carb dog food overall. This high-protein, grain-free formula provides concentrated nutrition without high levels of carbohydrates.
