Foods which are ‘free-from’ have become increasingly popular in the supermarket. You’ve probably noticed as you browse through the aisles, that many foods are ‘dairy-free, ‘gluten-free’ or ‘soy-free’, and consumers lap them up on the assumption that ‘free-from’ foods are healthier or more natural.

Over the past decade, consumer interest in pet nutrition has been on the rise. And it’s no surprise, as after all, pets are part of the family, so why shouldn’t they also have the most healthy, natural foods? The ‘free-from’ craze has also toppled over into the market, and many owners are now seeking boutique, exotic-ingredient and grain-free (BEG) diets. In 2017, according to the U.S. Bureau of Labor and Statistics, $31.1 billion was spent on the development and manufacturing of pet food. This huge sum of money has been exponentially increasing year on year, and the demands for grain-free and BEG diets have been a large influence.

Buying Guide

The truth is, the idea that grain-free dog food is better for your pup has been rooted in a non-scientifically backed myth. It’s a common misconception that grains are linked to allergies or gluten intolerance, or are filler ingredients and linked to high carbohydrate contents. Yes, many grain-free diets are excellently constructed, and some dogs do much better on a grain-free diet, but if your pet isn’t one of them, grains can be very healthy for him.

So, what are the Most Common Grains found in Dog Food?

  • Wheat
  • Barley
  • Corn
  • Oats and oatmeal
  • White rice
  • Brown rice
  • Rye
  • Sorghum  

Grains are an excellent source of fiber, protein, vitamin E and omega oils. They are particularly healthy if they are whole grains, which are more natural than refined grains. 

Some grain-free dog food brands have, in fact, been associated with health implications. Heart disease is more commonly observed among dogs fed a BEG or grain-free diet due to’ dilated cardiomyopathy’ or’ DCM’. DCM is a heart condition where the walls of the heart become thin and flaccid, resulting in less ability to deliver effective pumps of the blood around the body. Eventually, the blood pressure inside the heart causes the weak walls to dilate and increase the heart’s size. 

The exact link between DCM and grain-free diets is still not fully understood, however, it is believed to be linked to a taurine deficiency in dogs who eat these diets. There have been suggestions that the deficiency could be from a primary dietary deficiency in taurine, reduced bioavailability, increased losses of taurine in the feces, or a change in the metabolism in the body of taurine.

The FDA (U.S. Food and Drug Administration) has been passively recording data on the topic, and due to recent awareness, many grain-free diets are now adding taurine to their ingredients list, to avoid the development of DCM.

However, not all grain-free dog foods are bad. In fact, many are excellently compiled. Also, a small minority do benefit from a grain-free diet, as each dog has its own unique nutritional needs. So, if your pet is particularly sensitive to grains, finding the right grain-free dog food is important. You should look for high-quality food which is fully nutritionally balanced. Your vet can be a great resource for information on which brands might suit your dog.   

Advantages of No Grain Food for Dogs

While the advantages of grain-free diet are not rooted in science, their popularity indicates some advantages to feeding certain individual dogs on grain-free formulations. 

These include:

1. Not all Grains are healthier than vegetables

Whole grains are wonderful, healthy ingredients that are full of nutrients such as fiber, vitamins, protein, and omega oils. They can help regulate digestion and boost health. However, not all grains are healthier than vegetables. Many cheaper companies will use refined grains. Whole grains contain the endosperm, germ, and bran, whereas refined grains only contain the endosperm. This reduces their nutritional value considerably. Refined grains are considered ‘filler’ ingredients, creating bulk and adding fewer valuable nutrients than their weight is worth. In these cases, healthy vegetables and fruit are much better alternatives.

2. Some dogs have intolerances to Grains

Grain allergies and intolerances are uncommon. Food allergies account for <1% skin allergies, and <10% of general allergies. Among them, most food allergies are to animal proteins and not grain. However, it is important to note that even though they are rare, they are not impossible. Some dogs truly are intolerant and have reactions to foods containing grains. 

3. Grains can increase Flatulence

In comparison to other ingredients, grains can ferment more than other ingredients during the digestion process, leading to excess gas being produced. This is low down in the intestinal tract. Therefore, it doesn’t cause gastric bloating, but for some dogs, it can cause flatulence. Low-quality, refined grains are more likely to cause this issue, rather than whole grains. It should be noted that other ingredients such as lactose, potatoes, and table scraps are also common causes of flatulence. Also, an imbalance in the gut microbiome (friendly, commensal bacteria) also increases methane production. The good news is, many grain-free diets have additional probiotics to aid digestion.

What to look for in Dog Food without Grains

When searching for a new food, whether it is normal or grain-free, there are many things to consider. It is not as simple as picking one off the shelf based on how appealing the packaging is. Doing your research, and even contacting the manufacturer directly is really important. Therefore, it takes more time than just making a decision in the pet store. The following questions should be considered:

Does the manufacturer employ a qualified nutritionist?
  • An animal nutritionist should either have a Ph.D. in animal nutrition, or be board-certified by the American College of Veterinary Nutrition, or the European College of Veterinary Comparative Nutrition.
Does the Diet formulation meet AAFCO nutrient profiles?
  • These are guidelines set out by the AAFCO (Association of American Feed Control Officials), which detail how much of every nutrient and mineral the food should contain based on the life-stage of your dog (for example, puppy or adult). Some packaging will show an ‘adequacy statement’ stating that it meets AAFCO standards, others you will need to phone the manufacturer to confirm.
Where is the Food manufactured?
  • Sometimes the packaging will state ‘produced in the USA’. Home country products are best, as you can be assured that the ingredients are of a higher quality and that there is less of a carbon footprint on the manufacturing of the food.
Are the Ingredients of high quality?
  • The ingredients list is in order of weight, and therefore the first ingredient has the highest quantity. Meat proteins should be first on the list, followed by high-quality carbohydrates, such as pumpkin. Some grain-free diets substitute grain with highly refined starches such as potato and cassava, which do not add nutritional value, so this should be considered when looking at grain-free diets. 
Does the recipe have added taurine?
  • The addition of taurine may lower the risk of grain-free diet-associated DCM, although specific levels needed to prevent DCM have not been scientifically established.
Does the food suit the life-stage of your dog?
  • Different foods are formulated for different life-stages. A young, growing dog should be on puppy food, as this has higher levels of protein and calcium to aid growing muscles and bones. A senior dog should be on a senior food, as this has higher levels of omega oils for aching joints as well as a lower calorie content to address a more sedentary lifestyle.
What do the consumer reviews say?
  • Looking at consumer reviews will give you a good understanding of how the food is at ground level. Reading how the food affected dogs first-hand, for better or for worse, is a valuable insight into the product.

FAQ – Veterinary Recommendations

👩‍⚕️ Is Grain-Free Food better for Dogs?

There is no scientific evidence that grain-free food is better for dogs than a high-quality grain inclusive diet. Common myths related to this type of food are that grains are a common cause of allergies, grain-free pet foods are lower in carbohydrates, grains cause gluten intolerance and that grains are filler ingredients. These are all incorrect, and grains, especially whole grains, are incredibly beneficial to your dog’s health. For a tiny proportion, grain-free dog food will suit them better due to mild gut or skin sensitivities, however, this is the exception and not the rule.

🐶 Do dogs need these diets?

Dogs do not need grain-free diets to be healthy. Grains, especially whole grains, are excellent sources of fiber, minerals, protein, omega oils and vitamin E (an antioxidant that improves the immune system). Grain-free diets may suit dogs with skin or gastrointestinal sensitivities, however, for many of these dogs, a grain-free diet will not make any difference.

🐾 Are there any problems with Drain-Free diets?

Grain-free diets do carry health risks. The main risk associated with them is the development of dilated cardiomyopathy (DCM). The exact link between the diet and condition is still unknown, however, it is suspected that taurine levels play a role. Dilated cardiomyopathy is a serious condition, which can lead to heart failure, and therefore buying a grain-free diet with a suitable taurine level is essential. Also, grain-free diets are sometimes associated with high-fat content. This is because some try to have a low carbohydrate content, and therefore the calories must come from a different nutritional source. High-fat content is not suitable for all dogs, especially dogs who are overweight or have suffered from pancreatitis in the past.

🐕 Is it true that Dogs are Allergic to Grains?

Food allergies are uncommon in dogs. Less than 1% of skin allergies are related to food, and less than 10% of all other types of allergies, such as gastrointestinal-related allergies, are from food. Of these allergies, animal proteins such as chicken, beef and dairy products are the most common causes. However, grain allergies and sensitivities do exist, but they are infrequent in dogs.

🐾 Are grains and Gluten-Intolerance linked?

Gluten intolerance (also known as celiac disease) in humans is a hereditary autoimmune condition, linked to hypersensitivity to wheat (and sometimes barley and rye) gluten proteins. In dogs, it is extremely rare, and there has only been one report of it from a single inbred Irish Setter family. Therefore, even though grains will cause problems for those afflicted with gluten intolerance, it is not something that should cause pets.

🦴 Are Grain-Free Diets carbohydrate-free?

By removing grains from a diet, a carbohydrate source is removed. However, most grain-free diets contain other carbohydrate sources such as pumpkin, sweet potatoes and potatoes. Some of these have an even higher carbohydrate content than grains themselves, and therefore grain-free diets are not carbohydrate-free. But that isn’t a bad thing, as carbohydrates are an essential energy source and a necessary nutrient required for life. Some grain-free diets specifically aim to be low in carbohydrates and substitute grains for peas, lentils or beans. These are healthy ingredients, but for some dogs, these will cause more of a gastrointestinal upset than grains would have. These diets which are low in carbohydrates also have a higher fat content, which is not suitable for overweight dogs or dogs who are prone to developing pancreatitis.

🐶 Which are good and which are bad Grains?

Whole grains are grains that contain the endosperm, germ, and bran, whereas refined grains only contain the endosperm. Therefore, whole grains are more nutritional for your pet. This does not mean that processed grains are bad for your dog, but they do not provide as many nutrients as whole grains. Grain can be either a whole grain or refined grain, and therefore it is important to check the packaging to determine how much it has been processed. A typical example of a refined grain is white rice, and its wholegrain version is brown rice.
