Purina Pro Plan Natural Dog Food receives the Advisor’s mid-tier rating of 3 stars.

The Purina Pro Plan Natural product line includes seven dry dog foods.

Each recipe below includes its related AAFCO nutrient profile when available on the product’s official webpage: Growth, Maintenance, All Life Stages, Supplemental or Unspecified.

• Purina Pro Plan Natural Duck and Rice [M]
• Purina Pro Plan Natural Turkey and Barley [A]
• Purina Pro Plan Natural Grain Free Small Breed [M]
• Purina Pro Plan Natural Chicken and Brown Rice [A]
• Purina Pro Plan Natural Grain Free Tuna and Egg [M]
• Purina Pro Plan Natural Grain Free Lamb and Egg [M]
• Purina Pro Plan Natural Grain Free Chicken and Egg [M]

Purina Pro Plan Natural Turkey and Barley was selected to represent the other products in the line for this review.

The first ingredient in this dog food is turkey. Although it is a quality item, raw turkey contains about 80% 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 is brewers rice. Brewers rice is a cereal grain by-product consisting of the small fragments left over after milling whole rice. Aside from the caloric energy it contains, this item is of only modest nutritional value to a dog.

The third ingredient is barley. Barley is a starchy carbohydrate supplying fiber and other healthy nutrients. However, aside from its energy content, this cereal grain is of only modest nutritional value to a dog.

The fourth ingredient is chicken meal. Chicken meal is considered a meat concentrate and contains nearly 300% more protein than fresh chicken.

The fifth ingredient is dried egg product, a dehydrated form of shell-free eggs. Quality can vary significantly. Lower grade egg product can even come from commercial hatcheries — from eggs that have failed to hatch.

In any case, eggs are easy to digest and have an exceptionally high biological value.

The sixth ingredient is brewers yeast can be a controversial item. Although it’s a by-product of the beer making process, this ingredient is rich in minerals and other healthy nutrients.

Fans believe yeast repels fleas and supports the immune system.

Critics argue yeast ingredients can be linked to allergies. This may be true, but (like all allergies) only if your particular dog is allergic to the yeast itself.

In addition, a vocal minority insists yeast can increase the risk of developing the life-threatening condition known as bloat. However, this is a claim we’ve not been able to scientifically verify.

In any case, unless your dog is specifically allergic to it, yeast can still be considered a nutritious additive.

What’s more noteworthy here is that brewers yeast contains about 48% protein, a factor that must be considered when judging the actual meat content of this dog food.

The seventh ingredient 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 item could come from almost anywhere: roadkill, spoiled supermarket meat, dead, diseased or dying cattle — even euthanized pets.

For this reason, we do not consider generic animal fat a quality ingredient.

The eighth ingredient is oatmeal, a whole-grain product made from coarsely ground oats. Oatmeal is naturally rich in B-vitamins, dietary fiber and can be (depending upon its level of purity) gluten-free.

The ninth ingredient is pea protein, what remains of a pea after removing the starchy part of the vegetable.

Even though it contains over 80% 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 meat content of this dog food.

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 product.

With five notable exceptions…

First, we find pea fiber, a mixture of both soluble and insoluble dietary fiber derived from pea hulls. Aside from the usual benefits of fiber, this agricultural by-product provides no other nutritional value to a dog.

Next, fish oil is naturally rich in the prized EPA and DHA type of omega-3 fatty acids. These two high quality fats boast the highest bio-availability to dogs and humans.

Depending on its level of freshness and purity, fish oil should be considered a commendable addition.

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

Next, this food also contains 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.

And lastly, this 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.

Purina Pro Plan Natural Dog Food
The Bottom Line

Judging by its ingredients alone, Purina Pro Plan Natural looks like an average dry product.

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 31%, a fat level of 19% and estimated carbohydrates of about 42%.

As a group, the brand features an average protein content of 31% and a mean fat level of 19%. Together, these figures suggest a carbohydrate content of 43% for the overall product line.

And a fat-to-protein ratio of about 61%.

Above-average protein. Above-average fat. And below-average carbs when compared to a typical dry dog food.

When you consider the protein-boosting effect of the pea protein in this recipe and the canola meal contained in other recipes, this looks like the profile of a kibble containing a moderate amount of meat.

Bottom line?

Purina Pro Plan Natural is a plant-based dry dog food using a moderate amount of chicken meal as its main source of animal protein, thus earning the brand 3 stars.

Recommended.

Please note certain recipes are sometimes given a higher or lower rating based upon our estimate of their total meat content and (when appropriate) their fat-to-protein ratios.
