Picking the best food for your dog is one of the most important decisions that you’ll ever make for them. A well-balanced, high-quality diet can make the difference between top canine health and nutritional deficiency. So, it’s essential to get it right.

For some dogs, the best nutrition means a grain-free doggy diet. A grain-free diet is precisely what it sounds like, a diet containing zero grains.

Whether your dog does better on this type of diet, or perhaps it’s a choice that you’ve made after researching grain-free vs. grain-inclusive diets, this guide is a must-read.

The Grain-Free Dog Food Debate

Grain Free Dog Food
Grain-free can be great for sensitive stomachs, but some studies have linked it to serious health concerns.

So, before we jump into our top grain-free choices, it’s important to talk you through the grain-free dog food debate. In the world of human nutrition, many of us choose to ditch grains to reduce bloating, improve skin texture, lower depression, and many other reasons. But what are the reasons for choosing a grain-free diet for our dogs?

There are many reasons why some dogs need a grain-free diet. It could be a definite intolerance to grains or certain types of grain. Or perhaps your dog is being tested for allergens, and your vet had suggested a temporary grain-free diet. Some dogs are less gassy without grains, and some parents simply think it’s a better option for their pup.

With the rise in popularity of grain-free, gluten-free, paleo, and other diets for humans, pet food brands are creating all kinds of similar options for our Fidos. However, in 2018, the FDA announced that they were looking into a potential link between grain-free diets and an increased rate of dilated cardiomyopathy (DCM), a life-threatening heart condition. This investigation worried some owners, and rightly so. However, in 2020, the FDA confirmed that they had not found a causal link between grain-free diets and the rise of DCM.

The takeaways are very mixed among all concerned audiences. Despite this recent announcement, many vets, canine nutritionists, and owners remain wary of grain-free diets, while many feel reassured that it is okay to feed grain-free nutrition. Nonetheless, you must be armed with the latest facts when picking the proper diet for your canine. So, if your dog needs or prefers a grain-free diet, the FDA believes there is no reason not to choose one, but it is always wise to check with your vet as there may be other reasons to reconsider.


Ingredients to Look For

A well-balanced diet contains specific components to meet one’s nutritional needs.

Whether your dog needs grain-free or grain-inclusive nutrition, all dogs need a well-balanced diet. Below we have listed the main food groups your dog needs and what ingredients to look out for in the ingredients list.

Whole Meats

One of the greatest signs of high-quality dog food is when meat is the first ingredient, regardless of the diet. Whole meats and meat-specific meals (aka, beef meal, chicken meal, etc.) are rich in protein, and should be the main components of your dog’s meal plan. Meat provides essential amino acids needed to maintain healthy muscles and overall maintenance. It also supplies energy, fats, vitamins, minerals, and a yummy taste.

Meat meals are concentrated protein which is highly nutritious for dogs and can provide up to four times as much protein as whole meats. Some brands prefer to stick to whole meats only, but as long as it is listed as a specific animal-sourced meat meal, it is an excellent ingredient for Fido. Avoid ingredients such as “meat derivatives” or “poultry meal,” as you cannot determine what specific meat or animal by-product it contains.

Healthy Carbohydrates

Healthy carbohydrates are essential in a dog’s diet because it provides energy that meat alone cannot provide. Healthy carbs are natural ingredients such as grains, but these are ingredients that you want to avoid if you are looking for a grain-free diet. Instead, you need to look for ingredients such as potatoes, peas, and lentils that provide energy. They are also nutritious, providing extra fiber, vitamins, minerals, and other antioxidants. If your dog struggles to digest these items, you might benefit from reviewing these options as well.

Omega Fatty Acids

Fats have earned themselves a bad reputation, but a dog would become very sick without them. Healthy fats are essential during the developmental period, needed for brain and eye development. Plus, they support skin and coat health, offer bone and joint support, aid digestion, enhance nutrient absorption, and improve overall wellness. Great sources of healthy fats include meat meals, fish, fish oils, eggs, and plant oils.

Fruits & Vegetables

Fruit and vegetables are essential for dogs, as they provide necessary vitamins and minerals to keep their immune system healthy, which enables them to fight illness and disease. Fruits and veggies also provide fiber, which is vital for gut health. Plus, it helps them feel fuller for longer, meaning they can maintain a healthy weight.

Glucosamine

Glucosamine is a crucial component of a dog’s diet as it supports joints. This is particularly important if you have a larger breed, very active pup, or senior pooch whose joints need extra support. Even if your pooch is a small breed or doesn’t have joint problems when they are young, you can set them up with healthier joints by choosing a diet with glucosamine.

Glucosamine is commonly found in high-quality products compared to lower-quality products. Glucosamine is provided through added supplements or sources, including meat meals, fish oil, eggs, and green-lipped mussels. Suppose the food you choose does not have a suitable level of glucosamine. In that case, you can add additional glucosamine supplements under the direction of your vet.

Natural Preservatives

Natural is not necessary but is highly recommended as the healthiest dietary option for your dog. Natural food is essential if your dog chooses a grain-free diet because they have a sensitive digestive system. Artificial preservatives and other unnatural ingredients can irritate the doggy digestive system, so it’s essential to avoid them.

Preservatives are required to make sure that the food arrives in your dog’s bowl fresh and safe to eat. Natural preservatives include ascorbic acid (vitamin C), mixed tocopherols (vitamin E), and botanical oils such as peppermint and rosemary extract. If you find food coloring in the ingredients list, ditch the product straight away. The presence of food coloring is a sure-fire sign of a poor-quality product.

Frequently Asked Questions

Various grain free dog foods next to each other in open cans
Here are some of the most frequently asked questions about all things grain-free dog food and doggy diets.

Are grain-free diets healthier than grain-inclusive diets?

Not necessarily, as it all depends on your dog and their individual dietary needs. If your dog is doing well on a grain-inclusive diet, there is no reason to change them to a grain-free diet. As the saying goes, “if it ain’t broke, don’t fix it.” However, if your vet has suggested taking grains out of their diet, either for digestive or allergy reasons, it could be better for them. Be sure to discuss any concerns you have with your vet, who can offer you tailored nutritional advice.

Are grain allergies common in dogs?

Although many dogs are allergic to grains, grains are not the most common reason for doggy allergies. Research shows that specific protein allergies are more common in dogs than grain allergies. The most common allergies include beef, chicken, eggs, and dairy. Allergy symptoms include itchiness, ear infections, gastrointestinal problems, chronic gas or diarrhea, or sore feet. If you are thinking about switching to a grain-free diet because of these symptoms, you could do an at-home allergy test from EasyDNA but also speak to your vet first to rule out other potential concerns.

Are grain-free foods safe for my dog?

Yes, according to the most recent update from the FDA, grain-free foods are safe for your dog. There was initial concern that grain-free diets could be linked to the rise in DCM cases across the country. However, after much intense research, there is no causal link between the two. Research is still ongoing, but as long as the food you choose is AAFCO compliant and high-quality, grain-free foods are safe for your dog.

Why are grains used in dog food?

Contrary to what some people say, grains are not used as cheap fillers. Depending on the grains used, they are highly nutritious and beneficial for your dog’s health. They are a great source of vitamins, minerals, energy, and fiber. However, high-quality grain-free recipes deliver with nutritious, healthy, and tasty ingredients as well. Common grain alternatives are sweet potatoes, peas, and lentils.

What makes good-quality grain-free dog food?

There are a few signs of high-quality grain-free dog food to consider when choosing a grain-free product for your dog. The first is that the primary ingredient should always be real meat or meat meal. Protein is the most crucial component of doggy nutrition, regardless of whether they need a grain-free or grain-inclusive diet. A grain-free product should be AAFCO compliant, well-balanced, and contain healthy carbs, healthy omega fats, fruits, veggies, and natural preservatives.

Can I feed my puppy a grain-free diet?

There is no reason why you cannot feed your puppy a grain-free diet, just as long as the product is deemed to meet the needs of developing puppies. Developing puppies need higher protein, energy, and healthy omega fats to assist with brain and vision development. A product should state on the packaging in the nutritional guide whether it meets the needs of developing puppies according to AAFCO guidelines.


Final Thoughts

Over the last few decades, the popularity of grain-free dog diets has increased. And despite the FDA announcement mentioned above, they are still a top choice for many dog owners. But remember that whether you are looking to update your dog’s grain-free diet or you are making the switch between grain-inclusive and grain-free, it’s crucial to speak to your vet about nutritional changes.

The most recent studies led the FDA to announce no causal links between grain-free diets and DCM.
