Grain-Free or Grain-Inclusive: Is Grain-Free Dog Food Better?

When choosing the right food for your dog, you’ve probably come across the debate: grain-free vs. grain-inclusive—is grain-free dog food better? With so much conflicting information out there, it’s easy to feel overwhelmed. Let’s break it down simply, so you can make the best decision for your pup.
What Does Grain-Inclusive Mean?
Grain-inclusive dog food contains grains like rice, barley, oats, or wheat as a source of complex carbohydrates, which are more slowly digested compared to simple carbohydrates, providing a more sustained source of readily available energy. These grains also provide dietary fibre, essential nutrients, including vitamins and minerals. Some dogs thrive on grain-inclusive diets, especially if they have no grain sensitivities.
On the other hand, grain-free dog food is made without grains, often substituting them with alternative carbohydrate sources like sweet potatoes, lentils, or peas.
Is Grain-Free Dog Food Better?
The answer isn’t one-size-fits-all—it depends on your dog’s individual needs. Here’s a look at the key differences:
Potential Benefits of Grain-Free Dog Food
Great for Dogs with Grain Sensitivities
Some dogs have grain allergies or intolerances that can lead to itching, digestive issues, or ear infections. Removing grains can help alleviate these symptoms. Grain-free does not mean carbohydrate-free, as complex carbohydrates are found in many non-grain ingredients such as peas, lentils, chickpeas, tapioca, potatoes, and sweet potatoes.
Higher Protein Content
Many grain-free pet foods are higher in protein than their grain-inclusive counterparts.
Grain replacements (e.g., peas, legumes, lentils) are a good source of carbohydrates by also providing a good source of protein as well, so grain-free diets tend to be a bit higher in protein as a result.
While extra protein is typically not a problem for most healthy pets, it can be problematic in certain medical conditions such as later stages of kidney disease, or pancreatitis in the case of increased fat.
Easier Digestion for Some Dogs
While most dogs tolerate grains and gluten without any issues, some may digest grain-free formulas more easily, especially those with sensitive stomachs.
Gluten-free diets are necessary for humans diagnosed with celiac disease or nonceliac gluten sensitivity, but this is not a common problem in pets and most tolerate gluten without any difficulty. The exception is some Irish Setters with inherited gluten sensitivity.

Potential Benefits of Grain-Inclusive Dog Food
Although carbohydrates are not considered essential nutrients and are often mislabeled as “fillers,” they do play a critical role in your pet’s body. In particular, carbohydrates provide a highly digestible, readily available energy source. Foods which are rich in complex carbohydrates are also an important source of essential nutrients.
The shape, texture and density of kibble and wet food also depend on the carbohydrate (starch) content of the food. This is important, as mouthfeel and the structure of food help to determine palatability.
Whole grains like brown rice, barley, and oatmeal provide essential fibre, which supports gut health by promoting regular digestion and healthy stool consistency.
Fibre-rich diets can also aid in nutrient absorption and help maintain a balanced microbiome in the digestive system. Additionally, grains offer a natural source of essential vitamins, minerals, and antioxidants that contribute to overall well-being.
So, Is Grain-Free Dog Food Good for Dogs?
Grain-free food can be a great option for some dogs, particularly those with specific dietary needs. However, it’s important to look beyond just “grain-free” and focus on overall ingredient quality. Whether you choose grain-free or grain-inclusive, your dog’s food should be nutritionally balanced, high in quality protein, and suited to their specific needs.
How to Choose the Best Food for Your Dog
Check the Ingredients List – High-quality protein should be the first ingredient, with wholesome sources of carbohydrates and fats.
Consider Your Dog’s Needs – Age, activity level, and health conditions all play a role in determining the best diet.
Consult Your Vet – If you’re unsure whether grain-free or grain-inclusive is best, your veterinarian can provide guidance based on your dog’s health.
