Red items when present indicate controversial ingredients
The first ingredient in this dog food lists chicken. Although it is a quality item, raw chicken contains about 80% water. After cooking, most of that moisture is lost… reducing the meat content to just 20% of its original weight.
To reflect its lighter mass, this item should more accurately occupy a lower position on the list.
Which brings us to brewers rice… the second and (more likely) the dominant ingredient in this dog food.
Brewers rice represents the small grain fragments left over after milling whole rice.
This is an inexpensive cereal grain by-product and not considered a quality ingredient.
The third ingredient is wheat. Now, contrary to what you may have heard, wheat isn’t necessarily a bad ingredient.
On the other hand, although there’s no way to know for sure here, the wheat used in making many pet foods can be similar to the kind used to make feed for livestock.
And that can sometimes be problematic.
What’s more, wheat is commonly linked to canine food allergies1.
For these reasons, we rarely consider wheat a preferred component in any dog food.
The fourth ingredient is poultry by-product meal… a dry rendered product of slaughterhouse waste. It’s made from what’s left of slaughtered poultry after all the prime cuts have been removed.
In a nutshell, poultry by-products are those unsavory and inedible leftovers deemed “unfit for human consumption”.
This stuff can contain almost anything… feet, beaks, undeveloped eggs… you name it.
What’s more, this item doesn’t even specify the source animal (is it chicken, duck or pigeon?).
On the brighter side, by-product meals are meat concentrates and contain nearly 300% more protein than fresh poultry.
The fifth item is corn gluten meal. Gluten is the rubbery residue remaining once corn has had most of its starchy carbohydrate (the good stuff) washed out of it.
Compared to meat, glutens are inferior grain-based proteins low in many of the essential amino acids dogs need to sustain life.
This inexpensive plant-based ingredient can significantly boost the total protein content reported in this dog food.
The sixth item is animal fat. Animal fat is a generic by-product of “rendering”… the same high-temperature process used to make meat meals.
Since there’s no mention of a specific animal, this stuff could come from almost anywhere… restaurant grease, slaughterhouse waste, diseased cattle… even euthanized pets.
Needless to say, generic animal fat is not a quality ingredient.
The next ingredient is corn. Corn is subject to the same problems and shortcomings as wheat (previously discussed). That’s why we don’t consider corn a quality addition either.
The eighth ingredient is soy flour… a high-protein by-product of soybean processing.
Soy protein has a low biological value compared to meat.
The ninth ingredient is corn bran. Corn bran is made from the tough outer layer of a corn kernel and is especially rich in dietary fiber.
The tenth ingredient is soybean meal. Soybean meal is actually a by-product. It’s what remains of soybeans after all the oil has been removed.
Soybean meal contains 48% protein… inferior plant-based protein. So, it has the ability to raise the reported protein content of any dog food product.
Fish meal is another high protein meat concentrate.
Unfortunately, this particular item is anonymous. The term “fish” does little to properly describe this ingredient. What species? What parts?
Fish meal is commonly made from the by-products of commercial fish operations.
What’s more, the controversial chemical ethoxyquin is frequently used as a preservative in fish meals.
But because it’s usually added to the raw fish before processing, the chemical does not have to be reported to consumers.
We find no public assurances from the company this product is ethoxyquin-free.
Without knowing more, and based upon this fish meal’s location on the list of ingredients, we would expect to find only a trace of ethoxyquin in this product.
Animal digest is a (generic) chemically decomposed concoction of unspecified body parts… from unspecified animals. Believe it or not, animal digest is usually sprayed onto the surface of a dry kibble to improve its taste.
From here, the list goes on to include a number of other items.
But to be realistic, ingredients located this far down the list (other than nutritional supplements) are not likely to have much of an effect on the overall rating of this product.
With two notable exceptions…
Garlic oil may be a controversial item. We say “may be” here because we are not certain of the oil’s chemical relationship to raw garlic itself.
In rare cases, garlic has been linked to Heinz body anemia in dogs.2
Most of the professional literature we surveyed did not provide any conclusive warnings regarding the use of garlic… especially in small amounts (as it is here).
Although we see no reason to be overly concerned, we do feel it is a mistake to include such controversial ingredients in any dog food product.
Unfortunately, this Pro Plan product also contains menadione… a controversial form of vitamin K linked to liver toxicity, allergies and the abnormal break-down of red blood cells.
On a more positive note…
This dog food appears to contain chelated minerals… minerals that have been chemically attached to protein. This makes them easier to absorb. Chelated minerals are usually found in better dog foods.
Purina Pro Plan Dry Dog Food
The Bottom Line
Judging by its ingredients alone, Purina Pro Plan appears to be a below-average kibble.
But ingredient quality by itself cannot tell the whole story. We still need to estimate the product’s meat content before determining a final rating.
The dashboard displays a dry matter protein reading of 30%, a fat level of 18% and an estimated carbohydrate content of 44%.
As a group, the brand features an average protein content of 31% and an average fat level of 17%. Together, these figures suggest an overall carbohydrate content of 44% for the full product line.
Average protein. Average fat. And near-average carbohydrates… when compared to a typical dry dog food.
Yet when you consider the plant-based protein-boosting effect of the corn gluten meal, this is the profile of a kibble containing only a modest amount of meat.
What’s worse, it’s difficult to ignore the unusual abundance of Red Flag items.
Bottom line?
Purina Pro Plan is primarily a grain-based dry dog food using only a fair amount of chicken, beef or lamb as its main sources of animal protein… thus earning the brand two stars.
Not recommended.
