I have a number in my head that I’m slightly embarrassed to share. In the first year of owning Churro, my French Bulldog. I spent somewhere around three hundred dollars on dog food that I now know I should never have bought. Different bags, different brands, all with impressive sounding names and packaging that screamed ‘premium.’ All of them, when I finally learned to read a label properly, contained ingredients that had no business being in my dog’s bowl.
The pet food industry is enormous and largely unregulated in terms of marketing claims. A brand can call itself ‘natural,’ ‘premium,’ or ‘wholesome’ without those words meaning anything specific at all. The only thing that actually tells you what’s in the bag is the ingredient list on the back and most people, including me for a long time, don’t know what they’re looking at.
This article is my attempt to fix that. I’m going to walk you through the specific ingredients that are red flags on any dog food label, explain why each one matters, and then name the brands that consistently show up with these problems. I’m not a vet. I’m a dog owner who spent too much money learning this the hard way, and I’d rather you didn’t have to.
Let’s start with the ingredients. Because the brands only matter once you understand what you’re looking for.
QUICK ANSWER – What dog food brands should you avoid?
Avoid any brand whose label lists BHA, BHT, or ethoxyquin as preservatives, corn or wheat as the first ingredient, vague ‘meat by-products’ or ‘animal digest,’ artificial dyes like Red 40 or Yellow 6, or corn syrup. Brands that consistently appear with these issues include Kibbles ’n Bits, Pedigree, Gravy Train, Alpo, and Ol’ Roy. The full explanation ingredient by ingredient and brand by brand is below.
First, Let Me Teach You How to Actually Read a Dog Food Label
Before I name a single brand, I want to give you the skill that makes this article actually useful long-term. Because brands change formulas. New bad brands launch every year. If you know what to look for on a label, you don’t need anyone to give you a list you can evaluate any bag yourself in sixty seconds.
The First Five Ingredients Rule
Ingredients are listed in order of weight, from most to least. This means the first five ingredients make up the vast majority of what’s actually in your dog’s food. If those first five are mostly grains, by-products, and fillers that’s what your dog is primarily eating. A food that lists ‘Ground Yellow Corn’ as the first ingredient is a corn-based food, regardless of what the front of the bag claims.
What you want to see: A specific, named meat source in the first position. ‘Deboned Chicken,’ ‘Lamb,’ ‘Salmon’ actual named proteins. What you don’t want: ‘Meat,’ ‘Poultry,’ or anything preceded by ‘Animal.’ Vague means low quality and low transparency
The AAFCO Statement
Every legitimate dog food should carry an AAFCO nutritional adequacy statement somewhere on the packaging. It will say something like: ‘formulated to meet the nutritional levels established by AAFCO Dog Food Nutrient Profiles.’ If this is missing entirely, that’s a serious red flag. It means the food hasn’t been validated against minimum nutritional standards.
The Specific Ingredients to Avoid And Why Each One Matters
This is the section I wish I’d had when I first got Churro. I’m going through each red flag ingredient one by one what it is, why it’s in there, and why you should care.
RED FLAG: BHA (Butylated Hydroxyanisole) and BHT (Butylated Hydroxytoluene)
These are synthetic chemical preservatives used to stop fats from going rancid and extend shelf life. They’re cheap and effective, which is why budget brands love them. The problem: BHA and BHT have been linked to cancer in lab animal studies, and they bio-accumulate meaning they build up in your dog’s system over time with repeated exposure. BHA is actually listed as a possible human carcinogen. Several countries have restricted or banned these in human food, yet they remain legal in pet food in the US.
What you want instead: Mixed tocopherols (natural Vitamin E), ascorbic acid (Vitamin C), or rosemary extract. These preserve food naturally without the chemical concerns.
RED FLAG: Ethoxyquin
Another synthetic preservative, originally developed as a pesticide and rubber hardener. It’s been linked to liver and kidney damage in dogs at high doses. The FDA has asked manufacturers to voluntarily reduce it, and most reputable brands have moved away from it. But it still shows up in some budget foods, particularly in fish-based formulas, where it’s sometimes added to fish meal before it even reaches the dog
food manufacturer.
RED FLAG: Meat By-Products and Animal Digest
This is the one that got me the most when I first understood it. ‘Meat by-products’ can legally include things like lungs, kidneys, and intestines which aren’t inherently terrible but also bones, blood, and fatty tissue. The problem isn’t just the quality. It’s the vagueness. You genuinely don’t know what you’re getting because it’s not specified. ‘Animal digest’ is even more vague, it’s a chemically treated slurry of various animal parts used as a flavour coating on kibble. It’s essentially the thing that makes terrible food smell appealing to dogs.
RED FLAG: Corn, Wheat, and Soy as Primary Ingredients
These grains aren’t inherently toxic, so I want to be precise here. The problem is when they appear as the first one or two ingredients, because that means your dog is eating primarily grain, not protein. Corn and wheat are cheap sources of calories and bulk, they’re used to make a bag look and feel full without the cost of real meat. Dogs can digest grains, but their digestive systems are designed primarily for protein. A corn-first formula is a budget product dressed up as dog food.
Corn gluten meal is a step worse, it’s a by-product of corn processing used as a cheap protein booster. It inflates the protein percentage on the label without providing the amino acid profile your dog actually needs.
RED FLAG: Artificial Dyes: Red 40, Yellow 5, Yellow 6, Blue 2
I genuinely laugh every time I see these in a dog food. Your dog is completely colour blind to red. They cannot see yellow the way you do. These dyes serve absolutely zero nutritional purpose and exist entirely to make the food look appealing to the human buying it. The irony is brutal.
Beyond being pointless, artificial dyes have been linked to hyperactivity and allergic reactions in sensitive dogs. Red 40 in particular has been a subject of concern in both human and animal research. There is no legitimate reason for any of these to be in your dog’s food.
RED FLAG: Corn Syrup and Added Sugars
Yes, some dog food brands add corn syrup. Why? Because dogs have sweet receptors and sugar makes food taste better, which means your dog eats more of it and you buy it again. It’s the same reason ultra processed human snacks are addictive. Corn syrup adds no nutritional value whatsoever, contributes to weight gain and blood sugar instability, and is a marker of a brand that is optimising for palatability over nutrition.
RED FLAG: Propylene Glycol
A synthetic additive used to keep semi-moist foods soft and chewy. It’s banned in cat food by the FDA but somehow still permitted in dog food. It’s a humectant, it absorbs water, which is also used in antifreeze, though in a different form. For dogs with sensitivities, it can cause digestive issues. More importantly, it’s another signal that a brand is choosing cheap chemistry over real food.
Dog Food Brands to Avoid – And Exactly Why
Now that you understand the ingredients, the brands make sense. I want to be clear about how I’m approaching this section: every callout below is based on publicly available ingredient information, FDA recall records, and documented consumer complaints. Formulas do change over time, so I’d always recommend checking the current label yourself. But these are the brands that have consistently appeared with red flag ingredients across multiple reviews and databases.
I’m also not saying these foods will harm every dog. Some dogs eat Pedigree for ten years and seem fine. I’m saying: when you know what’s in them, you can make a more informed choice. That’s all.
Kibbles ’n Bits
Corn is the first ingredient. Contains artificial colours (Red 40, Yellow 5, Yellow 6, Blue 1). High in sugars. Minimal real meat protein. Has faced recalls including detection of elevated euthanasia drug pentobarbital in some dry products in the past. This is budget food dressed up with bright colours that appeal to human buyers, not dogs.
Pedigree
One of the world’s best selling dog foods and one of the most ingredient compromised. Corn and wheat appear as primary ingredients in most
formulas. Contains meat by products, artificial colours, and corn gluten meal. The marketing is enormous; the ingredient quality is not. Better options exist at similar price points.
Gravy Train
Made headlines in 2018 when testing revealed trace amounts of pentobarbital, the drug used to euthanize animals in some products. Also contains BHA as a preservative and relies heavily on corn based ingredients. This is one of the clearest examples of fundamental manufacturing and sourcing failure in the pet food industry.
Alpo
Contains meat by products, soy, and artificial colours throughout its product range. Protein content is boosted by cheap plant based sources rather than named animal proteins. Has had multiple recalls over the years. The ‘hearty’ branding does not reflect the ingredient reality.
Ol’ Roy (Walmart Brand)
Walmart’s own-brand dog food, and the ingredients reflect the price point. Ground yellow corn as the primary ingredient in most formulas. Heavy use of by products, artificial colours, and corn syrup in some lines. At this price point, real meat protein cannot be the primary ingredient, the economics simply don’t work.
Beneful (Purina)
Worth mentioning separately because Purina makes genuinely good products (Pro Plan is widely respected by vets) but Beneful is a different story. Contains propylene glycol in some formulas, artificial colours, and sugar. Multiple consumer lawsuits have been filed over the years, though Purina maintains the food is safe. The point is: brand name recognition means nothing. Always read the sub-line label.
One more important note: I am not a vet and I am not saying any of these brands will cause specific health problems in your specific dog. What I am saying is that based on publicly available ingredient analysis and recall history, there are much better options available at similar or comparable price points. The choice is yours.
So What Should You Actually Look For? A Positive Checklist
I don’t want to leave you with just a list of what not to buy. Here’s the positive checklist what good dog food actually looks like on a label.
A Quick Note for Each Breed – Why These Ingredients Hit Differently
I cover four breeds on this site, and I want to be specific about why these red flag ingredients are particularly worth avoiding for each of them.
French Bulldog
Frenchies have brachycephalic airways and famously sensitive stomachs. Corn-first foods and artificial dyes hit harder on this breed because their digestive systems are already working against them. Chicken by products are a very common sensitivity trigger for Frenchies specifically. Any food with vague ‘poultry by products’ and corn as a primary ingredient is a recipe for the kind of gas that will clear a room. I know this personally. In vivid detail.
Labrador Retriever
Labs will eat anything. Genuinely. This is both their greatest charm and their greatest vulnerability when it comes to food. A corn heavy, sugar added formula will be inhaled happily by most Labs but it contributes directly to the weight gain issues this breed is so prone to. Corn syrup and high carb fillers in a breed that already has almost no natural portion control is a bad combination.
Golden Retriever
Goldens are prone to skin and coat issues and can be sensitive to certain additives. Artificial dyes and chemical preservatives like BHA can aggravate skin sensitivities in this breed. If your Golden has recurring skin issues or a dull coat and you’re feeding a brand from the avoid list above, the food is worth examining as a contributing factor.
German Shepherd
GSDs have sensitive digestive tracts and are prone to bloat a serious and potentially life-threatening condition. Cheap fillers like corn and soy contribute to gas build up, which is a risk factor for bloat in deep chested breeds. A food full of corn by products and artificial additives is a particularly poor choice for a German Shepherd. High quality, named protein as the first ingredient is non-negotiable for this breed.
FAQs – What People Ask Me About Dog Food Brands to Avoid
Q: Is Purina a dog food brand to avoid?
Purina is a big family of products and the answer is genuinely ‘it depends.’ Purina Pro Plan is widely recommended by veterinary nutritionists and has strong feeding trial data behind it. Purina Beneful, on the other hand, contains artificial dyes, propylene glycol in some formulas, and has faced consumer lawsuits. Same parent company, very different products. Always read the specific sub brand label.
Q: Is Royal Canin a dog food brand to avoid?
Royal Canin is a vet recommended brand with extensive breed specific research behind it. It’s not on my avoid list. The ingredient list is not as clean as premium natural brands you’ll see corn and by products but the formulations are backed by nutritional science and feeding trials, which many boutique natural brands don’t have. It’s a mainstream option I’d consider acceptable, not ideal.
Q: What is the number one worst dog food ingredient?
If I had to pick one: BHA. A synthetic preservative that bio-accumulates in your dog’s system over time, is classified as a possible carcinogen, and has zero nutritional benefit. There is no good reason for it to be in your dog’s food when natural alternatives like mixed tocopherols exist. If I see BHA on a label, I put the bag back.
Q: Is grain-free dog food better?
Not automatically. Grain free doesn’t equal healthy, some grain-free formulas replace grains with legumes like peas and lentils, which have their own ongoing questions around heart health in dogs. The question is always: what are the first five ingredients? A grain inclusive food with named meat first and whole grains is often better than a grain free food where peas are the first ingredient.
Q: How do I check if a dog food has been recalled?
The FDA maintains an updated searchable recall database. DogFoodAdvisor.com also tracks recalls with brand specific history pages and sends email alerts for new recalls. I’d recommend bookmarking both and checking any new food before you commit to it.
Final Word from Raza
The three hundred dollars I spent on the wrong food for Churro taught me something that no amount of reading would have. You can’t trust the front of a bag. You can’t trust the brand name. You can’t trust a price point. The only thing you can trust is the ingredient list and only once you know what you’re looking at.
I genuinely hope this article saves you some of that money. And more importantly, I hope it saves your dog from eating food that isn’t good enough for them. They can’t read the label. That’s our job.
