Is your dog allergic to grains? You’ll be happy to know that grains aren’t necessary for a dog’s diet.

Don’t get me wrong, there are benefits to your dog eating grains, but if your dog is allergic to grains, the cons of having such in his diet far outweigh its benefits. Fortunately, with a grain-free diet, your dog can still live a healthy and happy life. 🙂

Unsure whether your dog has a grain allergy?

If your dog is allergic to certain grains, or all grains, you’ll notice one or more of the following symptoms after a meal containing grains:

  • Inflamed skin
  • Itchiness
  • Excessive flatulence
  • Diarrhea
  • Vomiting
  • Ear infections
  • Hair loss or bald patches
  • Sores and scabs

Even if your dog isn’t allergic to grains, putting him on a grain-free diet won’t hurt. On a grain-free diet, your dog will experience higher energy levels, less flatulence and shedding, smaller stools, and a shinier coat. 🐕

Plus, you get to worry less about your dog having a bad reaction to something he ate.

So, how can you tell which grain-free dog food is the best for your pooch?

There are a lot of dog foods out there with packaging claiming to be “grain-free.” Sadly, many of these foods aren’t as grain-free or as top-quality as they claim to be.

For the health and happiness of your pup, we’ve put together a list of grain-free dog foods you can trust for quality, taste, and your dog’s wellbeing. Every single one is truly grain-free, pet-safe, and highly nutritious.

How to Choose Best Grain-Free Food for Dogs

Grain-free dog food doesn’t contain any wheat, corn, or other grains. Grains are added to dog food as a source of carbohydrates, which are crucial for energy. Grain-free dog foods use other nutritious carb sources, such as potatoes and pea flour, as a substitute for grains.

They are available as wet and dry dog foods, and typically have a high protein content. If your dog shows allergy symptoms, such as diarrhea, puking, flatulence, or skin irritation, after eating a meal containing grains, talk to your vet to determine the exact cause of the allergic reaction.

Your dog can also benefit from a grain-free diet even if he isn’t allergic to grains, but to get grain-free dog food that offers all of the benefits and none of the downsides of switching to such a diet, look out for the following features.

What Things to Consider When Buying Grain-Free Dog Food

100% Grain-Free Labelled

Your regular dog food will contain grains as a source of carbohydrates. Such types of dog food are easier to find and typically cost less than grain-free dog foods. If you check the labels of such dog foods, you’ll see that their ingredients consist of one or more of the following grains:

  • Barley
  • Oats
  • Rye
  • Wheat
  • Corn
  • Rice
  • Soy

If your dog is allergic to grains, you’ll want a dog food with a label that contains none of these grains. Instead of these grains, a 100 percent grain-free dog food will use potatoes, pumpkin, or pea flour as its carb source.

Having a source of carbohydrates in your dog’s diet is important because it will provide the calories needed for an active lifestyle. It also provides fiber for a healthy digestive system. So, look out for a dog food that’s 100 percent grain-free but provides an alternative carb source.

Whole Proteins as Primary Ingredient

The best quality grain-free dog foods have a rich whole protein source as their first ingredient. The whole protein can be poultry, fish, or meat, such as beef or pork. Chicken and venison are common choices, but what counts as the right one for your dog will depend on his palate and his allergies.

For instance, your dog may be allergic to poultry, which means a grain-free recipe containing venison or fish will make for a better choice.

Vitamins and Minerals

Vitamins and minerals are essential for a balanced diet that will keep your dog healthy and active. The vitamins and minerals, including vital fatty acids, will boost your dog’s immune system, bone and muscle strength, mental performance, skin and fur quality, and more.

Natural Ingredients

Artificial additives and preservatives in your dog’s food can be injurious to his health. Always go for a dog food that uses strictly natural ingredients, such as actual meat, real fruits, and vegetables, instead of by-products or thickeners.

Fruits and Vegetables

The presence of fruits and vegetables in your dog’s food is a good sign that it contains natural ingredients and a healthy dose of essential vitamins and minerals.


What is the FDA warning about grain-free dog food?

The Food and Drug Administration (FDA) warns that a constant diet of off-the-shelf grain-free dog foods can cause canine dilated cardiomyopathy (DCM) in dogs. DCM is a condition that impedes your dog’s heart’s ability to pump blood.

It is caused by an enlarged and weakened left ventricle that prevents the heart from relaxing and filling with blood.

After reviewing over 500 cases of DCM, the FDA warns that the risk of developing such an ailment is more likely in dogs that eat grain-free dog foods from the following brands:

  • Blue Buffalo
  • California Natural
  • 4Health
  • Acana
  • Merrick
  • Natural Balance
  • Nature’s Domain
  • Fromm
  • Earthborn Holistic
  • Nutro
  • Orijen
  • Nature’s Variety
  • NutriSource
  • Taste of the Wild
  • Rachael Ray Nutrish
  • Zignature

Unfortunately, many of these are well-known and trusted brands—some of which we even still recommend. It’s up to you to do the research and weigh the pros and cons of any one food.

Does my dog need a grain-free diet?

There are a number of benefits your dog stands to gain from switching to a grain-free diet, but whether or not switching diets is the right choice for you and your bud will depend on various factors. If your dog isn’t allergic to grains, there’s no pressing need to switch to a grain-free diet. Very few dogs are actually allergic to grains and can thrive on a grain diet.

To figure out whether your dog requires a grain-free diet, talk to your vet. He/she will take into consideration the age and health of your dog to determine if switching to a grain-free diet is in your dog’s best interest.

You can also consider switching your dog’s diet if he exhibits the following symptoms after eating meals that contain grains:

  • Inflamed skin
  • Itchiness
  • Excessive flatulence
  • Diarrhea
  • Vomiting
  • Frequent ear infections
  • Hair loss or bald patches
  • Sores and scabs

If switching to a grain-free diet, be sure to do so gradually by mixing in higher protein dog food with regular dog food, gradually increasing the amount over time. This will give your dog’s digestive system time to acclimate and prevent a negative reaction, such as diarrhea or constipation.

This rule actually applies to any dog food switch. A sudden complete change-over is never recommended, even when switching a puppy to an adult formula of the same brand and product line.

Is it really healthier for a dog to eat grain-free foods?

While dogs have evolved to be able to digest grains, most vets still recommend that grains only make up a small part of your dog’s diet. A good ratio for a balanced doggy diet is 10 percent grains, 40 percent proteins, and 50 percent vegetables.

Dogs have an easier time digesting a grain-free meal, especially those with fewer carbs and more protein and animal fats. By switching your dog’s diet from grain to grain-free, your pooch will experience the following health benefits:

  • Stay fuller for longer after each meal
  • Reduced risk of canine food allergies
  • Healthier skin and coat
  • Smaller stools
  • Reduced flatulence

What is the difference between grain-free and gluten-free?

Grain-free dog foods are pet foods that contain no grains and use other foods as a carbohydrate source. On the other hand, gluten-free foods contain ingredients that have no gluten.

Gluten is a protein found in grains like wheat, rye, barley, and so on. Gluten-free dog food won’t contain such proteins. Because gluten is available in only some grains, all 100 percent grain-free dog foods will contain no gluten, while a gluten-free dog food may or may not be grain-free.
