What is the Best Grain Free Dog Food? 
Grain free dog food has become exceptionally popular in recent years, moving in tandem with the rise in popularity of grain and gluten-free diets for us humans.
The grain free pet food industry is not only growing, but developing, at a rapid rate. The popularity of grain free diets has led to an unprecedented explosion of the number of options available. The grain free movement is also evolving to encompass concurrent 'real food', 'ancestral', 'freeze dried' and 'raw' movements.
So, with an ever-growing number of grain free diets gracing the store shelves (or in our case, the web pages!), how do we navigate what seems like a simple question: What is the BEST grain free dog food?
What IS Grain-Free Food?
The definition of grain free dog food is a diet free from all grains, including wheat, corn, rice, oats and barley.
Is 'grain free' the same as 'gluten free'? No. Gluten refers to the proteins found in wheat, rye, barley and triticale. These are all classified as grains. However other grains exist which do not contain gluten, such as rice. Therefore, grain free food is always gluten free, but gluten free food may still contain some types of grains.
Fun fact: true coeliac disease (gluten allergy) is almost unheard of in dogs and cats, with the exception of Irish setters.
Is 'grain free' the same as 'filler free'? Don't be fooled into assuming that 'grain free' also means 'filler free', or 'carbohydrate free'. It's basically impossible to create kibble without some form of carbohydrate holding the biscuit together. This means that when manufacturers remove grains from the recipe, they often replace them with other carbohydrates such as potato, tapioca, or chick peas. Always check the ingredients if you aren't sure!
Is grain free dog food good for your dog?
This is a complicated question, but ultimately the short answer is: yes! Gone are the days when 'grain free' meant 'hyper holistic' and unbalanced nutritionally. Nowadays, most premium grain free dog foods are complete and balanced in accordance with international feeding guidelines. Furthermore, they actually tend to be very high in quality when compared to many cheap grain-based recipes, with most surpassing supermarket brands and hitting the premium bracket due to their ingredients. No empty husks of rice here, no sir!
"I heard that dogs can't digest grains properly - is that true?"There's a lot to be said on this topic, and you can read more about it in Dr Kim's comprehensive guide to grain free dog food. In short, while your poodle's distant relative may be the wolf, their digestive system has undoubtedly changed a lot over tens of thousands of years alongside humans. To contrast to wolves, domestic dogs have developed plant-digesting salivary and pancreatic enzymes which even cats don't possess! So, in general, most dogs can digest grains just fine.
However, grain free dog food may benefit your dog if they are allergic to grains. Much the same as a lactose intolerent person avoiding milk, a grain free diet is required if your dog is allergic.
But it's important to note that true grain allergies are very rare in dogs. Sure, many people anecdotally report an improvement in their dog's allergies when they swap to a grain-free diet, but the benefit may lie in the quality of the food and its digestibility, rather than the simple lack of grains.
See our section on allergies below for more information on grains and food allergies.
Does Grain Free Dog Food Cause Heart Disease?
In the last few years, veterinary cardiologists in the United States reported increased rates of a deadly heart condition, dilated cardiomyopathy (DCM), in Golden Retrievers and breeds which are not typically predisposed to DCM in general. Frequently these dogs were noted as being fed 'botique, exotic or grain free' diets, or BEG diets for short.
At this stage, research is still ongoing and it is unclear as to the underlying cause of the reported cases of diet related DCM. Some possible theories include nutritional imbalances in the foods themselves, unknown effects of certain exotic ingredients such as legumes, fruits, flaxseeds etc, or even potentially an unknown toxin.
For pet parents concerned about nutritional deficiencies, feeding a rotational diet may help. A rotational diet offers a your dog with some variety while also reducing the risk of a deficiency developing from feeding a particular diet over an extended period of time. Rotational feeding involves offering your dog a combination of high quality diets, ideally varying protein sources and formats (eg. dry, freeze dried, wet).

3. Best Grain Free Food For Allergies (Novel / Single Protein Formulas)
Can my dog go grain free for allergies?
Many people report their dogs doing very well on grain free diets, improving problem conditions such as itchy skin or tummy problems. However, grain free diets will only benefit dogs that are allergic to grains. True food allergies are not actually that common in dogs, with less than 5% of dogs found to have a food allergy. And when a true allergy does exist, the most common allergies are to meat proteins including chicken, beef, or pork, rather than grains.
That said, grain free dog foods can still be a good way to eliminate the itchies: they often use low-allergenic, novel proteins such as kangaroo, duck, salmon, venison, bison and more, reducing the risk of an upset tummy or skin.
Therefore, in order to create a list of 'the best grain free diets for food allergies', we have selected our top novel protein grain free diets. Not only are these free from common allergens such as chicken, pork, dairy, soy and beef, but they are also free from less common allergens such as wheat and other grains.
