Buying Guide for Grain-Free Dog Food

Ready to switch to grain-free dog food? Here’s what you need to know.

Is Grain-Free Dog Food Healthy?

It can be. Some dogs are allergic to grains and gluten, so avoiding them will make them feel better. However, some dogs shouldn’t be fed grain-free formulas. 

Some dogs are prone to canine dilated cardiomyopathy (DCM) if they don’t eat grains. This affects their cardiac muscle and makes it hard for their heart to pump blood through their body.

While the cause of canine DCM is unknown, factors like a lack of taurine and grains in food have been studied

DCM occurs higher in specific breeds — like Great Danes, Boxers, Golden Retrievers, and Cocker Spaniels. These dogs typically need grains. However, always check with your veterinarian to see if a grain-free or grain-inclusive diet is better for your dog. 

Why Do Dogs Need a Grain-Free Diet?

A grain-free diet is helpful for dogs who have food allergies or sensitivities to grains. If you notice your pup has itchiness, excessive hair loss, inflamed skin, and “hot spots,” they may need to avoid grains. 

Benefits of Grain-Free Food Options

There are quite a few benefits of grain-free food. If you’ve found that your dog can’t properly digest grains, you may be ready to switch. Here’s what to look forward to: 

  • Reduced inflammation in joints (since the body is no longer fighting off allergies or intolerances)
  • Improved digestion and firmer stool (because grains can irritate sensitive tummies in certain dogs)
  • Higher cognitive function (since grain allergies can also affect thinking and cause “brain fog”)
  • Clearer skin and a shinier coat (because grain allergies can cause itchiness, small bumps, and a dull coat in certain dogs)

And there may be even more benefits. Of course, these will vary from dog to dog. 

What to Look For When Buying Grain-Free Dog Food

What should you look for when buying grain-free dog food? Here’s what to keep an eye on.  

Meat Protein as the First Ingredient

Whether they’re eating grain-free or not, dogs need high-quality protein. It’s essential to focus on real animal meat as the first ingredient — including (but not limited to) pork, chicken, fish, lamb, and beef. 

Healthy Fats

Fats are super crucial, especially in grain-free dog food. This is because fats are your dog’s #1 source for energy production and heart health (with omega fatty acids).

So, focus on top sources like fish oil, coconut oil, and meat fats (like chicken, lamb, and beef). 

Vitamins and Minerals 

Commercial dog foods already offer the correct percentages of vitamins and minerals for dogs as per AAFCO recommendations.

But, supplemented vitamins and minerals like glucosamine, l-carnitine, taurine, and calcium can be extra beneficial for dogs, especially when they aren’t eating grains. 

No Fillers and Additives

Additives and fillers are used to cut costs for manufacturers. But, they usually don’t offer many additional benefits to your dog.

Luckily, it’s harder for them to include these ingredients with grain-free foods. But, you should still avoid artificial colors, flavors, preservatives, and by-products that aren’t disclosed as what they are.

In worst-case scenarios, these additives have caused severe health issues. 

Our Verdict

Now that you’re ready to make the leap into grain-free foods, you can feel confident in choosing the best option for your pup. 

My top choice is Wellness CORE Grain-Free Wild Game Duck dry dog food

It’s suitable for most adult dogs, includes novel proteins to keep gut health in tip-top shape, and is free of fillers. 

But even if you choose one of the other grain-free options on this list, your dog will be in good hands. And, each one is tasty and healthy, giving you both peace of mind. Of course, if you have any questions, feel free to talk to your vet. 


Want to know more about buying Grain-Free dog food? Here are a few common questions and their answers.

Is grain-free food a better option for my dog?

That depends. Your dog needs carbohydrates to produce energy. But they eat grain too often, it can cause obesity, lack of gut health, and decreased energy. If your veterinarian approves a grain-free diet, it can be a great way to get in more wholesome ingredients — like animal proteins and healthy fats. 

Just remember that any grain-free option that you choose still has ample fiber, taurine, and vitamins like zinc. These are essential nutrients found in grains that need to be supplemented in grain-free diets.

Should puppies be fed grain-free food?

Puppies can eat grain free dog food. A grain-free diet can benefit puppies who have grain allergies and food sensitivities. However, you should check with your veterinarian first. 

Can my dog digest grains if he has a sensitive digestive system?

Sometimes. The most common intolerances are specific proteins, soy, and corn. But many dogs can still digest grains like rice and oatmeal. However, if your dog can’t, a grain-free diet is a great choice. 

Do vets recommend grain-free food?

Vets recommend grain-free dog food for certain dogs, especially if they have grain allergies. But, it’s important to discuss any diet changes with your veterinarian before switching your dog’s food. They will be able to tell you whether it’s suitable for your dog’s blood sugar, allergies, and overall health.
