16 Worst Dog Food Brands To Avoid (+16 Top Choices)

Unfortunately, not all dog foods are created equal!

That’s why it’s essential to learn about the worst dog food brands and discover the best dog foods of 2023, to ensure your furry friend is getting the nutrition they deserve.

The list is based on factual data regarding the percentage of all the ingredients used in the various dog foods.

What makes the dog food brands on this list worth avoiding is that they fail to provide many—if any—of those nutrients your dog needs to stay healthy. Instead, they use a variety of low-quality ingredients and types of filler.

These can be harmful or unnamed ingredients that make them bad choices. Below you can find our research. The top worst dog foods didn’t change too much from previous year.

We structured the following list of dog food brands to avoid this year in a way that will make it easy for you to make a more informed shopping decision.

You will have a better understanding of why it is critical to seek out the better option for your pup by first emphasizing the bad dog food and then reading about healthy dog food brands to choose from.

16 Worst Dog Food Brands to Avoid This Year

Worst Wet Dog Food: Cesar Filets

Cesar Filets is considered one of the worst dog foods because of its high salt content (we covered the best low sodium dog food options).

Cesar Filets worst dog food brand

It has sufficient water for processing, animal liver, chicken, beef and meat by-products, wheat gluten, ground wheat flour, cornstarch, salt, pea fiber, sodium tripolyphosphate, calcium carbonate, added color, choline chloride, magnesium.

It helps if you also understand that the quality of ingredients cannot tell the whole story, but the amount of meat in the dog food is critical to consider before determining whether it falls in the best or worst category.

The amount of protein in Cesar filet is about 44%, with 22% fat and 25% carbohydrates.

This analysis shows that this dog food includes an above-average level of protein intake and just near-average fat.

At the same time, the carbs are below average compared to a portion of typical canned dog food.

Another factor making it a low-quality dog food is that it has artificial colorings added to it, which is useless and not preferred.

Worst Dog Treats: Sportmix Wholesomes Biscuits

Sportmix biscuit treats are on the list of dog food brands to avoid because it is made of unwanted dry leftovers and includes preservatives and fats harmful to dogs.

Sportmix Wholesomes Gourmet Biscuits

If we estimate the product’s meat content, it shows that it contains about 24% protein content, 13% fat, and about 54% carbohydrates.

After analyzing these numbers, it is clear this is a poor choice and is just a bit above average compared to other high-quality dog foods.

Worst Adult Dry Dog Food: IAMS Proactive Health

The primary ingredient in IAMS Proactive Health Adult Chunks dry dog food is chicken.

Though chicken is a quality item and raw chicken comprises about 80% water, but when cooked, most of the water is lost, which reduces the meat content to just a portion of its initial weight.

Worst Adult Dry Dog Food – IAMS Proactive Health Adult Chunks

After processing, these ingredients would probably account for a smaller fraction of the whole content of the finished food.

The second ingredient is cornmeal which is coarse ground flour made from the dried corn. Corn is a controversial and inexpensive cereal grain of low nutritional value to a dog.

For that reason, it is not a preferred part of any dog food.

The third ingredient of this product is sorghum (milo), a starchy cereal grain with a similar nutrient profile to corn.

Because it is gluten-free and claims a smoother blood sugar performance than other grains, sorghum may be considered a satisfactory non-meat ingredient.

The fourth ingredient is chicken by-product meal, which is a dry product of the slaughterhouse waste.

This meal is made after all prime cuts have been separated, which includes almost anything left, including beaks, feet, and even undeveloped eggs, anything except the feathers.

But on the bright side, these portions are meat concentrates and comprise protein approximately 300% more than the fresh chicken.

The fifth ingredient is beet pulp, a controversial ingredient, as it is a high fiber by-product made of sugar beet processing.

Although this food contains all the amino acids a dog needs, it is still considered a low-quality dog food.

Worst Puppy Food: IAMS ProActive Health Smart Puppy

Pups are very much like human children in the sense that what you feed them early on can have a significant impact on their growth and development.

Iams ProActive Health Smart Puppy Original Formula is the worst puppy food even though it may contain the phrase “Health Smart” on its label.

Worst Puppy Food- IAMS ProActive Health Smart Puppy

In one disturbing case, a dog owner on the Consumer Affairs website observed that her pet displayed indications of a parasite soon after eating this food.

However, a vet confirmed the digestive health issues arose due to the food, and no parasites were present in the dog, luckily.

Kal Kan Complete Adult

This dog food makes the list because of questionable ingredient quality that is not nutritional and is somewhat harmful to dogs.

Kal Kan Complete Adult Dog Food

The primary ingredient is corn, which we just mentioned does not provide the proper nutrition your dog needs.

The second ingredient is meat and bone meal which is a dry product from the mammal tissues, including bones, exclusive of any added hair, blood, hoof, hide trimmings, horn, manure, rumen contents, and stomach.

Meat and bone meal may have a lower digestibility than most of the other meat meals.

Scientists believe that this decreased absorption may be because of the lower essential amino acid and higher ash content in the ingredient.

The meat itself can come from any mixture of cattle, pigs, goats or sheep, making classifying impossible for particular food allergens.

Although meat and bone meals are still considered meat concentrates rich in protein, a generic ingredient like this cannot be considered a quality item.

Kal Kan’s third ingredient is a soybean meal which a by-product or leftover of soybean oil production more often found in farm animal feed.

Although soybean meal comprises about 48% of protein, this ingredient would be estimated to have a lower biological value than meat.

Inexpensive plant-based ingredients like this can boost the total protein, an element that must be considered while judging the actual meat content of this dog food.

The fourth ingredient is wheat which is another cereal grain and possesses the same issues as corn.

The fifth ingredient includes chicken leftovers or animal by-products, a dry leftover product of slaughterhouse waste.

I think you get the point that these types of ingredients are not ideal for your furry friend.

Twin Pet Dry Dog Food

Twin Pet dog food is a plant-based dry dog food utilizing a limited amount of unnamed and unidentified meat as its primary source of animal protein.

Twin Pet contains cheap ingredients of poor quality that do not provide the necessary nutrition to dogs.

Twin Pet Dog Food

Like the dog food brands we already discussed, the first ingredient is corn, so you already know how we feel about that.

The second ingredient is wheat middlings, also known as wheat mill run. It is a cheap by-product that remains after cereal grain processing.

Unfortunately, the disparities in nutrient content in the wheat middlings can be a critical concern in determining their aptness for being used in any dog food or even livestock feeds.

In actuality, wheat middlings is just the milling dust as well as floor sweepings. It is an ingredient that is typically associated with low-quality pet foods.

The third ingredient is the meat and bone meal, a rendered product from the mammal tissues. It has lower digestibility in comparison with the other meat meals.

Other unhealthy, non-nutritional ingredients in this dog food include unspecified animal fat and salt. The quantity of salt is also unknown, making it difficult to determine the nutritional value of this ingredient.

Altogether this product is one of the worst dog food brands.

Gravy Train

Gravy Train is a dog food to avoid because it lacks nutritional items needed for the strong growth of the dog.

Gravy Train dog food brand to avoid

It is a meat-based canned food that utilizes a moderate amount of meat or poultry by-products as the primary source of animal protein.

Don’t Miss:

Purina Dog Chow

Purina has introduced many pet food brands manufactured by the Nestle Purina PetCare Company.

The company began as the Ralston Purina Company in 1893, and presently it includes more than half a dozen various product items.

Purina Dog Chow

Purina dog chow’s flaws include low-quality ingredients like grain wheat, soy and corn meal, artificial food coloring, preservatives, and flavors.

Unfortunately, many dog owners continue to buy these products because they are inexpensive and very well promoted.


Beneful is another product line that lies under the Purina umbrella of brands.

Purina released the brand in 2001 and its main draw is that its boxes come in various shapes, textures, and colors.

Beneful offers different varieties of dry dog food products and wet dog food that contains “real meats” like chicken, beef, and salmon.

Purina Beneful dog food

If you take a quick look at the ingredient list for some of Beneful’s food, you will find that they are likely outweighed by standard products and plant proteins, while there are some natural meats included.

For example, the Purina Beneful Original with Real Beef lists beef as the main ingredient but it also contains five fillers or by-products.

There are also numerous artificial ingredients in their dog foods.

Beneful’s wet dog food products are made with wheat, corn, soy ingredients, and artificial flavors.

The Pedigree Brand

This dog food is owned and produced by Mars PetCare, a subordinate of Mars, Inc., the sixth-largest privately held company in the United States.

Pedigree provides a wide variety of dry and wet dog food and other dog treats marketed as excellent food.

Pedigree Dog Food

They make products for adult dogs, senior dogs, puppies, and recipes for dogs of different sizes and other health and dietary needs.

If you check the ingredients list for most of these products, you will find that they do not vary in their formulation.

Many Pedigree products list whole grain corn as one of the first ingredients.

Not only is this ingredient a common food allergen for dogs, but it also provides below-average nutrition.

Most of their dog foods are heavy on carbs and filled with inexpensive fillers and artificial flavors.

The only reason this brand is popular because it is cheap and affordable.

See Also:

Kibbles ‘n Bits

This brand of dog food is easily one of the most popular brands on the market.

But a quick glance at their formulas demonstrates that not only is joy missing -their motto is Joy in every bite – from the ingredients list, but so are many high-quality ingredients which they claim that their food includes.

Kibbles 'n Bits dog food

Kibbles ‘n Bits dog food is supposed to be made with flavorful roasted meats like chicken and beef.

One look at the ingredients list on their dry food products will show they are very carb-heavy corn-based, which is the first ingredient in many cases.

Kibbles ‘n Bits wet dog food is also loaded with corn, wheat, and soy ingredients, making it a dog food to avoid.

Ol’ Roy Dog Food

The Ol’ Roy brand of dog food is manufactured/Produced by the Mars Group specifically to sell in Wal-Mart stores.

Though Ol’ Roy certainly belongs on the list of worst dog food brands of all time, it is still among the highest-selling in the United States.

Ol’ Roy Complete Nutrition Dry Dog Food

The key reason is probably the fact it is easy to find and the affordable price.

A review of the ingredients list for numerous Ol’ Roy products reveals they use corn, soy and wheat ingredients, cheap meat products and artificial flavors.

A 50-pound bag of Ol’ Roy dog food costs less than $25, another red flag because it is a low standard of dog food.

Original Line of Diamond Dog Food

The Diamond Pet Food Company is owned and produced by Schell & Kampeter, and comprises three product lines.

The original Diamond line of dog food lacks the desired nutritional content you should be looking for in your dog’s food.

Diamond dog food

A review of several Diamond dog food products reveals the use of corn, soy and wheat ingredients.

Many of the meat-based ingredients come from unnamed sources like fish meal or meat by-products of questionable quality.

They don’t use many artificial flavors and colors like other bad dog food brands on this list, so that’s a plus.

Still, it would be good to avoid any brand that makes heavy use of wheat, soy, and corn.

Blackwood 1000 Dog Food

Blackwood 1000 dog food has an ingredients list that’s full of items that deliver no health benefits to dogs and can even be harmful to their health.

Blackwood 1000 Dog Food

It also contains a lot of ingredients that are comprised of GMOs. Since many studies suggest that GMOs are not safe for human consumption, it’s certainly not a good idea to fill your dog with such foods daily.

Wegmans Bruiser Kibble Variety Mix

This brand of dry dog food has ingredients that have been considered dangerous for dogs to eat, including BHA, xantham gum, BHT, corn gluten, and food coloring.

Wegmans Bruiser Kibble Variety Mix demonstrates the motto that you typically get what you pay for.

Wegmans Bruiser Kibble Variety Mix dog food

It is affordable dog food, but if you’re looking to give your dog stable nourishment, you should look for an alternative option.

Alpo by Purina

After many complaints about dogs getting sick and dying that ate Alpo dog food – which Purina makes – it prompted the FDA to start an investigation into the company’s processing plants.

If the brand does not bother to meet basic production guidelines, then there is no need to consider it a healthy product for your dog.

What Dog Foods are Killing Dogs?

If you read about a recent FDA statement regarding grain-free dog food, please visit the links below for more detailed information.

It is important to note that they still have not found any evidence to say the dog food brands in their report directly cause these reported DCM cases.

Here is a direct link to the FDA’s investigation and their current findings.

At this time, there have been no recalls made on these brand’s products since the FDA’s findings are still inconclusive.

Champion Pet Foods, makers of Acana and Orijen, have updated their FAQs to address this topic which you can find here.

We always recommend consulting with your vet about your pup’s specific dietary needs.

Just like human food, there is no ‘one size fits all option for dogs either.
