7 Best Dog Foods without Corn, Wheat, and Soy

By Kevin Myers | 2021 Update

Buying food for your dog can be a difficult and overwhelming decision. Pet parents need to consider many things to make the best decision for their dog’s health. Your dog might evenhave allergies and specific nutritional needs.

When reading the ingredients on the packet, it is common to see ingredients such as meat, vegetables, grains, and fruits, but if you see corn, wheat, or soy in the list of ingredients, you should steer clear of making a purchase. While corn, wheat, and soy have been used as inexpensive filler ingredients in dog food for a while, many pet parents have noticed allergic reactions and digestive problems due to them.

After reviewing the available options, I have compiled a list of the best dog foods free of corn, wheat, and soy.

Buyer’s Guide

In current times, there is growing awareness about the nutritional needs of animals. While various options in the market can make it difficult, even overwhelming, to understand what’s best for your dog, information is also readily available to pet parents for guidance.

When you think of the ingredients you should watch out for in dog food, things like artificial additives and by-products often come to mind. These things can certainly affect your dog’s overall health, but you should also consider corn, wheat, and soy as part of the list. Many companies are making it a priority to craft formulas that are free of these harmful ingredients.

The Negative Impacts of Corn, Wheat, and Soy in Dog Food

You are probably wondering – what exactly could go wrong if my dog consumes corn, wheat, or soy? The reason why these ingredients can be harmful to your dog is listed below.

Impact on The Digestive System

  • While corn, wheat, and soy are relatively safe for humans to consume, they are plant-based ingredients. Dogs are carnivores whose intestines are used to digesting high amounts of protein and are not equipped to handle and absorb the nutrients available in plant-based forms. Not only can this result in indigestion, but a diet with corn, wheat, and soy fails to provide your dog with the nutrients it needs.
  • Wheat, corn, and soy are some of the most heavily genetically modified food sources and often contain pesticides. These negatively impact the digestive system and can cause severe inflammation in the digestive tract with repeated use.

Weight Gain and Obesity

  • When digested, the body turns corn into sugar which can raise your dog’s sugar levels, impacting its health. Corn may be added in the form of corn syrup, making the food addictive and overly sweet, leading to overeating, which is especially harmful to your dog if it has diabetes.
  • The inclusion of wheat and corn can also lead to weight gain in certain dogs. Improperly refined grains can yield more carbohydrate content than necessary for a balanced diet, leading to obesity.

Allergies

  • Wheat also contains gluten which is known for triggering allergies and sensitivities in many dogs.
  • These ingredients can also trigger allergies in dogs leading to upset stomachs, recurrent skin problems, and ear infections. There have also been incidences of some dogs experiencing severe itching around the face and paws. As a result, dogs might scratch the irritated areas, leading to open wounds that could become infected.

Other Issues

  • Soy contains chemicals called phytoestrogens which are similar to the reproductive hormone estrogen, which can cause issues with the reproductive system, such as hormonal imbalance.
  • The inclusion of corn, wheat, and soy can also lead to lower food quality. The core ingredients such as meat and vegetables are bulked up with these items, resulting in foods low in protein, amino acids, vitamins, and minerals.

The Benefits of Switching to Diets Free of Corn, Wheat, and Soy

Switching to a diet free of corn, wheat, and soy can benefit your dog’s overall health in many ways.

  • Since filler ingredients such as wheat, corn, and soy are absent, biologically appropriate nutrients are present in higher quantities, such as proteins, fiber, vitamins, and minerals, which results in a highly nutritious and well-balanced meal that keeps your dog strong and healthy.
  • With a meal free of these additives, your pet will feel fuller for longer and be more active.

  • If your dog is prone to digestive problems, a grain-free diet can also encourage healthy digestion and reduce the probability of flatulence issues and pooping more often. Nutrients are readily absorbed due to their species-specific nature.

Dog foods that do not contain wheat, corn, and soy are better options for dogs with diabetes and cancer. Complex and natural carbohydrates can aid in managing blood sugar levels.

Myths and Facts

In 2019, the Food and Drug Administration (FDA) investigated claims of a potential link between certain grain-free diets and Dilated Cardiomyopathy (DCM). Although no cause and effect were established, the issue became a topic of debate. There are still many academic researchers who strongly believe that grain-free diets may contribute to DCM.

However, a recent study published in June 2020 refutes these claims and found no clear link between grain-free diets and DCM. The peer-reviewed article has been published in the Journal of Animal Science and contained a comprehensive examination of almost 150 previous studies. The study established no definitive link between grain-free diets and DCM and called for further research and analysis.

These findings are good news for pet parents with dogs and puppies with grain-free diets. However, it is still important that you make an informed decision when buying foods free of wheat, corn, and soy. The mere absence of these ingredients does not make food the best for your dog.

How to Find The Best Dog Food Free of Corn, Wheat and Soy

While formulas free of wheat, corn, and soy are better than their alternatives, all dog foods are not created equal. High-quality food formulas usually share the following characteristics.

Rich in Meat Proteins

Real meat is the first ingredient in high-quality dog food instead of any fillers. Dogs are carnivores, so meat has to be the main ingredient in their diets for them to thrive. When real meat is the first ingredient in any dog food formula, you can rest assured that your dog will get the necessary amount of protein.

High Moisture Content

The average carnivorous diet is at least 70% water to meet daily fluid intake levels. Premium-quality dog food is also rich in moisture. Wet dog foods aid in preventing urinary infections, digestive issues, and other ailments your dog may experience. Additionally, it provides your dog with an adequate amount of fluids.

Minimally Processed Natural Ingredients

High-quality dog foods contain wholesome and natural ingredients that are minimally processed, which helps keep the original flavors and textures intact and does not diminish the nutritional value of the ingredients. When ingredients are cooked at high temperatures or heavily processed in other ways, they lose their initial flavor and nutritional content.

The Ingredients You Should Avoid in Dog Food

When purchasing grain-free dog food, check the label of ingredients to ensure the following don’t appear in the first few ingredients.

Meat Meal

Meat meal is made from animal parts that are unfit for consumption and usually consist of animal meats and organs cooked at high temperatures. It is not high quality like real meat and can also be difficult to digest.

Bone Meal

Bone meal is a powder made from ground bones and other leftover portions like cattle hooves. High quantities of bone meal in dog food can cause digestive issues and affect the kidneys.

High Levels of Carbohydrates

The starches from potatoes, green peas, and sweet potatoes are high in carbohydrates and biologically inappropriate. They can lead to weight gain and cause a variety of other health issues. The recommended amount of carbohydrate content in dog food is 20%.

Artificial Preservatives

Artificial preservatives in dog food include ethoxyquinBHT, and BHA, all of which are linked with health issues such as liver problems and cancer. Natural preservatives are made using vitamins C & E and are considered safe. These are present in the ingredient list as a type of “tocopherol” or “ascorbate.”

Carrageenan

Carrageenan is a thickening agent used for improving food texture. It has no nutritional value for dogs and can also cause inflammation in the digestive system.
