Ingredients Analysis

The first ingredient in this dog food 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.

The second ingredient is meat and bone meal, a dry “rendered product from mammal tissues, including bone, exclusive of any added blood, hair, hoof, horn, hide trimmings, manure, stomach and rumen contents”.1

Meat and bone meal can have a lower digestibility than most other meat meals.

Scientists believe this decreased absorption may be due to the ingredient’s higher ash and lower essential amino acid content.2

What’s worse, this particular item is anonymous. So, the meat itself can come from any combination of cattle, pigs, sheep or goats — which can make identifying specific food allergens impossible.

Even though meat and bone meals are still considered protein-rich meat concentrates, we do not consider a generic ingredient like this to be a quality item.

The third 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 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.

The fifth ingredient is 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 must be considered when judging the actual meat content of this dog food.

The sixth ingredient includes 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.

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.

After the egg and chicken flavor, we find wheat. Wheat is another cereal grain and subject to the same issues as corn (previously discussed).

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, we’re always disappointed to find artificial coloring in any 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, 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.

In addition, this recipe 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.

Next, garlic oil can be a controversial item. Although many favor the ingredient for its claimed health benefits, garlic has been linked to Heinz body anemia in dogs.3

So, one must weigh the potential benefits of feeding garlic against its proven tendency to cause subclinical damage to the red blood cells of the animal.

Additionally, we find no mention of probiotics, friendly bacteria applied to the surface of the kibble after processing to help with digestion.

And lastly, this food contains 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 its nutrient profiles, we question the use of this item in any canine recipe.

Nutrient Analysis

Based on its ingredients alone, Purina Dog Chow looks like a below-average dry dog food.

The dashboard displays a dry matter protein reading of 24%, a fat level of 11% and estimated carbohydrates of about 57%.

As a group, the brand features an average protein content of 26% and a mean fat level of 12%. Together, these figures suggest a carbohydrate content of 54% for the overall product line.

And a fat-to-protein ratio of about 47%.

Which means this Purina product line contains…

Near-average protein. Below-average fat. And above-average carbs when compared to a typical dry dog food.

When you consider the protein-boosting effect of the corn gluten and soybean meals, this looks like the profile of a kibble containing just a moderate amount of meat.
