Dried peas:
Dried peas are one of the significant components of dog food. But how are they controversial? Although they offer suitable dietary fibers and carbohydrates, they can lead to conditions like diarrhea, vomiting, and even DCM if given in a concentrated amount.
Garlic Oil:
Garlic may be a controversial ingredient of the Purina One Large breed puppy food. Maybe? What does that mean? While most of the vet nutritionists have explained the benefits of garlic, we are not sure if it is entirely adverse for the dog or not.
But the controversial thing about it is that when garlic reacts with oil, they have a chemical relationship that can affect the dog. These experts have linked garlic with Heinz body anemia in dogs, which is quite rare but possible. However, the small amounts of garlic haven’t shown any severe warnings in the case of Purina, one large breed puppy food warning.

The first ingredient in this dog food is chicken. Although it is a quality item, raw chicken contains up to 73% water. After cooking, most of that moisture is lost, reducing the meat content to just a fraction of its original weight.
After processing, this item would probably account for a smaller part of the total content of the finished product.
The second ingredient includes rice flour. Rice flour is made from either white or brown rice and is considered a gluten-free substitute for wheat flour.
The next ingredient is corn gluten meal. Gluten is the rubbery residue remaining once corn has had most of its starchy carbohydrate washed out of it.
Although corn gluten meal contains 60% protein, this ingredient would be expected to have a lower biological value than meat.
And less costly plant-based products like this can notably boost the total protein reported on the label — a factor that must be considered when judging the actual meat content of this dog food.
The fourth ingredient is corn. Corn is an inexpensive and controversial cereal grain. And aside from its energy content, this grain is of only modest nutritional value to a dog.
For this reason, we do not consider corn a preferred component in any dog food.
The next ingredient is chicken by-product meal, a dry rendered product of slaughterhouse waste. It’s made from what’s left of a slaughtered chicken after all the choice cuts have been removed.
In addition to organs, this item can also include feet, beaks, undeveloped eggs and almost anything other than prime skeletal muscle.
On the brighter side, by-product meals are meat concentrates and contain nearly 300% more protein than fresh chicken.
The quality of this ingredient can vary, depending on the caliber of the raw materials obtained by the manufacturer.
The sixth ingredient is wheat. Wheat is another cereal grain and subject to the same issues as corn (previously discussed).
The seventh ingredient lists soybean meal, a by-product of soybean oil production more commonly found in farm animal feeds.
Although soybean meal contains 48% protein, this ingredient would be expected to have a lower biological value than meat.
And less costly plant-based products like this can notably boost the total protein reported on the label — a factor that can’t be ignored when judging the actual meat content of this dog food.
The next item listed is beef fat. Beef fat (or tallow) is most likely obtained from rendering, a process similar to making soup in which the fat itself is skimmed from the surface of the liquid.
Although it may not sound very appetizing, beef fat is actually a quality ingredient.
After the natural flavor, we find glycerin. Glycerin is used in the food industry as a natural sweetener and as a humectant to help preserve the moisture content of a product.
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 affect the overall rating of this Purina product.
With 6 notable exceptions…
First, caramel is a natural coloring agent made by caramelizing carbohydrates. It’s used by pet food manufacturers to impart a golden brown tint to the finished product.
However, the concentrated version of this ingredient commonly known as caramel coloring has been more recently considered controversial and found to cause cancer in laboratory animals.
In any case, even though caramel is considered safe by the FDA, we’re always disappointed to find any added coloring in a pet food.
That’s because coloring is used to make the product more appealing to humans — not your dog. After all, do you really think your dog cares what color his food is?
Next, we find dried peas. Dried peas are a good source of carbohydrates. Plus they’re naturally rich in dietary fiber.
However, dried peas contain about 27% protein, a factor that must be considered when judging the meat content of this dog food.
In addition, chicory root is rich in inulin, a starch-like compound made up of repeating units of carbohydrates and found in certain roots and tubers.
Not only is inulin a natural source of soluble dietary fiber, it’s also a prebiotic used to promote the growth of healthy bacteria in a dog’s digestive tract.
Next, the minerals listed here do not appear to be chelated. And that can make them more difficult to absorb. Chelated minerals are usually associated with higher quality dog foods.
This recipe also contains sodium selenite, a controversial form of the mineral selenium. Sodium selenite appears to be nutritionally inferior to the more natural source of selenium found in selenium yeast.
And lastly, this dog food includes menadione, a controversial form of vitamin K linked to liver toxicity, allergies and the abnormal break-down of red blood cells.
Since vitamin K isn’t required by AAFCO in either of its dog food nutrient profiles, we question the use of this substance in any canine formulation.
Based on its ingredient panel alone, Purina One Dog Food looks like an average dry kibble.
The dashboard displays a dry matter protein reading of 30%, a fat level of 18% and estimated carbohydrates of about 44%.
As a group, the brand features an average protein content of 30% and a mean fat level of 16%. Together, these figures suggest a carbohydrate content of 45% for the overall product line.
And a fat-to-protein ratio of about 54%.
Which means this Purina product line contains…
Above-average protein. Near-average fat. And below-average carbs when compared to other dry dog foods.
However, when you consider the protein-boosting effect of the corn gluten and soybean meals and dried peas in this recipe and the inclusion of corn germ meal and soybean germ meal in other recipes, this looks like the profile of a kibble containing at least a moderate amount of meat.
