Pet parents searching for the best quality dog food are going against the grains and opting for a different source of carbohydrates for their fur-babies.

If your dog is a fussy eater or they have a grain allergy, grain-free dog foods might be a good alternative. Dogs still need carbs as part of their diet, so many grain-free dog foods replace grains with vegetables like potatoes and peas.

Trying to cut grains out of your pup's diet? We've rounded up the five best grain-free dog foods to help you make the best choice for your pet's dietary needs (and your budget!).

Open Farm Grain-Free Dry Dog Food

Vet recommended

Open Farm offers ten high-quality standard grain-free dry dog food options covering all life stages. All variations are free from preservatives and artificial flavors.

Open Farm sources all its meat from Certified Humane farms, and its seafood meets Ocean Wise and Seafood Watch sustainability standards. Each ingredient listed in Open Farm's grain-free dog food lists its origin for complete transparency.

Dr. Georgia Jeremiah, member of Wag!’s licensed veterinary team, personally recommends Open Farm to her own clients: “Open Farm dog food is formulated with high-quality ingredients and does not contain any artificial preservatives, flavors, or colors. The company also prioritizes the use of ethically sourced and humanely raised ingredients.”

Open Farm designs its recipes to keep fur-babies happy and healthy. One notable ingredient in its grain-free dog foods is coconut oil, a source of fatty acids that can help treat skin conditions and cognitive dysfunction syndrome (CDS).

As of May 2023, Open Farm grain-free dog foods have never been recalled. Open Farm grain-free recipes meet the Association of American Feed Control Officials (AAFCO) nutrient profiles for all life stages or maintenance (adults).

What pet parents say about Open Farm

"My Ozzie and Shelby were breaking out and skin rashes from the other food. I was feeding them from the vet. I turned to open Farms and found out that I could find out where all the ingredients came from and that my dogs love the food. Ozzie had a problem chasing after the ball and was sleeping all the time and once I turned to open farms, he runs after that ball."

"This food is great, my Maximus loves it, he actually eats all of it. Seems like his health has improved, he’s happier and less sluggish. The bite size of the kibbles is perfect for him as well. Will continue to purchase his food [from] Open Farm!"

Raised Right

Vet recommended

Raised Right boasts a selection of grain-free dog foods, with 11 recipes for adult dogs and puppies.

It's one of the best grain-free dog foods for protein sources — three of the top five ingredients in all variations are human-grade protein sources. For example, Raised Right’s Original Turkey Adult Dog Recipe lists turkey thigh, turkey liver, and turkey heart as the top three ingredients.

Dr. Jeremiah recommends Raised Right to her clients: “Raised Right offers a human-grade dog food consisting of only whole foods and no fillers or synthetic additives such as vitamin and mineral powders. Their ingredients can also be traced back to the source, and each batch is tested for safety.”

One reason Wag! loves Raised Right is that organic spearmint is one of the top five ingredients in many Raised Right recipes. Spearmint is rich in nutrients and antioxidants, containing vitamin A, vitamin B1, vitamin B6, folic acid, iron, magnesium, and more. Its formulas also contain flaxseed oil, a great source of omega-3 fatty acids.

Raised Right recipes meet the AAFCO nutrient profiles for maintenance (adults) or growth (puppies).

What pet parents say about Nom Nom

"Nom Nom has been delivering food for our picky Aussie/Border Collie mix for the last six months. He always eats it and he loves it. It is VERY convenient. If someone is watching him while we travel - we just send the correct number of pouches. So easy. We will not be [canceling] anytime soon."

"Nom Nom is the closest thing to dog food that my dog will eat. She is VERY picky and will often go 2 or 3 days without eating-even the Nom Nom. I have tried all the tips, but the tips are written by people not a persnickety 8 pound Chihuahua with a mind of her own. With all that said Nom Nom is a life saver in that at least she is eating something good and good for her."

What pet parents say about Wellness Core

"We have 2 golden-doodles. One can eat anything with no issues the other appears to have chronic digestive issues. We have been tried several different high end food over the last few years and finally decided to try a grain free brand. I am amazed that the tummy issues have stopped and both dogs are sated enough that there is food left in the bowl. Which was never the case with the cream colored one. He was always looking for more. The pellets are a bit larger than the other brands we tried so they actually get less than before. Our chow hound has made us need to regulate what is eaten so we measure the food vs leaving food down all the time. We are using the seafood brand."

"My dog loves this quality brand of dry food. He had serious skin allergy issues, but my search for the needed food for him ended after I found Wellness Core. His skin allergy problems disappeared, and he loves the food. Thank-you!"

FAQ

What does "grain-free dog food" mean?

Grain-free dog foods refer to any dog food that doesn't include rice, corn, cereal, oats, or wheat as one of its ingredients. Other grains commonly used in dog foods include millet, buckwheat, and certain grasses.

Is grain-free food better for dogs?

Grain-free dog food may benefit your pup, depending on their health and dietary requirements. Grains are a primary source of carbohydrates in many dog foods, so many grain-free dog foods contain potatoes and pea flour as alternatives.

Your vet may recommend grain-free dog food if your fur-baby has allergies, digestive issues, or skin conditions. Consult your vet before changing your dog to a grain-free diet.

Can grain-free dog food be bad for dogs?

There are some concerns that grain-free foods can be bad for dogs. In July 2018, the FDA began investigating potential links between grain-free dog foods and the development of canine dilated cardiomyopathy (DCM).

The study is looking at the relationship between DCM and grain-free dog foods that feature potatoes, legumes, and pulses (like peas and lentils) high in their ingredients lists.

It’s worth noting that the FDA states that potatoes, legumes, and pulses have been used in dog foods for decades and aren’t considered inherently dangerous to dogs. Grains also contain precursors to taurine, which is important to healthy heart function.

As of December 2022, the FDA’s investigation is ongoing, with no new scientific information to share at the time of writing.

Are grain allergies common in dogs?

Grain allergies are not as common as most allergies in dogs. A 2016 study involving 297 dogs found that beef, dairy, and chicken allergies were the most common, accounting for 66% of cases. Wheat — which is the most common grain allergy in dogs — came in fourth, affecting 38 dogs. Beef and dairy are the most common dog food ingredients that cause allergic reactions.

How does Wag! determine paw ratings for dog food?

Our editorial team conducts independent research when choosing foods to feature and how to rate them. Our paw ratings are largely based on the ingredients and nutritional content of each food. Here’s a quick guide to what our paw ratings mean:

1 paw: High filler content, meat not listed as first ingredient
2 paws: Meat meal, bone meal or meat by-products listed as first ingredient
3 paws: Named meat listed as first ingredient (e.g., chicken)
4 paws: Same as 3 paws, but also made with whole, limited ingredients and minimal processing
5 paws: Same as 4 paws, but made with human-grade ingredients, slow-cooked/cooked at low temperatures to preserve nutrient content; is vet-approved or has won awards from veterinary bodies; non-synthetic sources of vitamins, minerals, and antioxidants
Half-paws may be awarded for extra benefits, like affordability, trustworthiness, etc.
