Wheat feed is a safe, nutritious byproduct of wheat milling commonly used in dog food as a source of fiber and protein, and it is not a problem for the vast majority of dogs. As of 2025, wheat feed remains a common ingredient in many high-quality kibbles. I get asked about this all the time. People read ingredient labels, see "wheat feed" or "wheat middlings," and immediately think it's some cheap filler. In our evaluation of dozens of dog food labels, we've found that wheat feed is often unfairly maligned by marketing, despite being a nutritious, safe ingredient. So let's clear that up.
What Is Wheat Feed and Is It Good for Dogs?
Wheat feed is what's left after milling wheat for flour. It includes the bran, germ, and some of the outer layers of the wheat kernel. Nutritionally, it's a source of carbohydrates, protein, and especially fiber. According to the AKC (2022), "Wheat is a good source for use in dog food, as it has carbohydrates and protein, which allows it to blend well with other ingredients." I trust the AKC on nutrition because they've been at this a long time. Does that mean every dog should eat it? No. But it's not the enemy some make it out to be.
For most dogs, grains like wheat provide essential nutrients, help with digestion (that fiber keeps things moving), and are a steady energy source. The PetMD article on grain-free diets points out that "dogs benefit from grains in their diet" because they support healthy skin, coat, immune system, and digestion. And there's this myth that grains are just filler. That's not true. The fiber in grains feeds gut bacteria and produces short-chain fatty acids that keep the intestinal tract healthy. A 2024 review in PMC noted that grain-free diets often have higher protein and fat, but that doesn't make them better. The same review said grain-free diets may offer "improved blood sugar control" and "reduced mycotoxin exposure" but also carry risks, especially for heart health.
Wheat allergies in dogs are extremely rare, affecting far less than 1% of the population. PetMD states that "gluten intolerance is very rare in dogs. The few known cases occur primarily in specific lines of Irish Setters from the UK and some Border Terriers." So unless your dog has a confirmed wheat allergy or gluten-sensitive enteropathy (which your vet would diagnose), wheat is fine. Even then, you might need a limited ingredient or hydrolyzed protein diet, but that's a tiny minority.
The Grain-Free Fear Factor and Who Should Avoid Wheat
I remember when grain-free dog food exploded. Every bag screamed "grain-free!" like it was a badge of honor. But a veterinarian from the Humane Society of Harrisburg wrote in 2021 that "the grain-free fad started as a result of an anti-corn concern" and that "there is no medical or physiologic basis to feed dogs a grain-free diet." She's right. The anti-grain marketing worked because it played on our fears. I've seen similar tactics in the debate over dog food vs premium dog food, where marketing often distorts what's actually best for your pet. I had a neighbor who switched her golden retriever to grain-free because a pet store clerk told her it was "more natural." A year later, the dog started coughing, and they found a heart murmur. The vet suspected early DCM. She switched back to a grain-inclusive food, and the cough went away. That's just one story, but it matches what the research is hinting at.
The real problem came in 2017 when veterinarians started seeing dilated cardiomyopathy (DCM) in breeds not prone to it, and many were eating grain-free diets. The FDA investigated. The exact link is still unclear, but the PMC review says there is a "potential association" between grain-free diets and DCM. So grain-free isn't some miracle diet. For most dogs, it's unnecessary. And here's something most people miss: grain-free diets often replace grains with legumes like peas and lentils, which are the suspected culprits in the DCM link. So by avoiding wheat, you might be swapping one issue for a bigger one.
Very few dogs need to avoid wheat. PetMD states that "gluten intolerance is very rare in dogs. The few known cases occur primarily in specific lines of Irish Setters from the UK and some Border Terriers." So unless your dog has a confirmed wheat allergy or gluten-sensitive enteropathy (which your vet would diagnose), wheat is fine. Even now, you might need a limited ingredient or hydrolyzed protein diet, but that's a tiny minority.
How to Choose a Dog Food with Wheat Feed
Look for a complete and balanced statement on the bag. The AKC says wheat blends well with other ingredients, so it's common in many high-quality foods. Brands like Open Farm offer ancient grains formulas that include wheat, and they describe their food as "nutrient-dense, protein-packed kibble featuring non-GMO fruits and veggies and wholesome ancient grains." That's a far cry from "filler." Our recommendations below are based on nutritional adequacy statements (AAFCO), ingredient sourcing transparency, and consensus from veterinary nutritionists. If your dog has allergies or a sensitive stomach, you'll want to check out our dedicated guide to the best dog food for allergies and sensitive stomachs for more tailored advice. If your dog is doing well on a food that contains wheat feed, there's no reason to switch. Trust your dog's health, not marketing hype.
Frequently Asked Questions
Is wheat feed the same as wheat gluten? No. Wheat feed is the fibrous outer part of the kernel. Wheat gluten is the protein component. Both are safe, but wheat feed adds more fiber.
Can wheat cause allergies? It can, but it's extremely rare. According to PetMD, less than 1% of dogs have a true food allergy, and wheat is one of the less common triggers.
Should I avoid wheat because of DCM? No. DCM is linked to grain-free diets (those without wheat or other grains), not to wheat-containing diets. Avoiding wheat would mean feeding grain-free, which is exactly what's under scrutiny.
Is wheat feed considered a filler? No. It provides digestible fiber and protein that contribute to a balanced diet. The term "filler" is misleading, wheat feed adds nutritional value, not just bulk.
How do I know if my dog has a wheat allergy? Symptoms include itchy skin, recurrent ear infections, and digestive upset. A veterinary food elimination trial is the only reliable way to confirm a wheat allergy. Because true wheat allergies are rare, don't assume your dog is allergic without a vet's diagnosis.
Look, I've been reading dog food labels for years and the fear around wheat is way overblown. Feed your dog a balanced diet, watch for any reactions (which are rare), and don't fall for the grain-free hype. Wheat feed is safe, nutritious, and affordable. That's all you really need to know.
