Purina Pro Plan Bright Mind Dog Food Review (Dry)

Purina Pro Plan Bright Mind product range is made up of three recipes which each receive the Dog Food Advisor’s rating, 4.5 stars.

The table below shows each recipe in this range including our rating and the AAFCO nutrient profile: Growth (puppy), Maintenance (adult), All Life Stages, Supplemental or Unspecified.

Recipe and Label Analysis

Purina Pro Plan Bright Mind Adult 7+ Chicken and Rice was selected to represent the other products in the line for detailed recipe and nutrient analysis.

Ingredients Analysis

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 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 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 poultry.

The quality of this ingredient can vary, depending on the caliber of the raw materials obtained by the manufacturer.

We consider poultry by-products slightly lower in quality than a single-species ingredient (like chicken by-products).

The third ingredient is rice. Is this whole grain rice, brown rice or white rice? Since the word “rice” doesn’t tell us much, it’s impossible to judge the quality of this item.

The next 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.

The fifth ingredient lists 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 next ingredient is wheat, another cereal grain and subject to the same issues as corn (previously discussed).

The seventh ingredient is corn germ meal, a meal made from ground corn germ after much of the oil has been removed. Corn germ meal is a protein-rich by-product left over after milling corn meal, hominy grits and other corn products.

However, the protein found in corn germ meal (about 25% dry matter basis) must be considered when judging the meat content of this dog food.

The eighth ingredient is medium-chain triglyceride vegetable oil (MCT), a fatty-acid supplement derived from palm kernel or coconut oil.

Medium-chain triglycerides have been shown to improve cognitive function in older dogs.¹

Because of its proven safety² as well as its potential to help in the treatment of canine cognitive dysfunction syndrome (CDS), MCT can be considered a positive addition to any senior recipe.

The ninth ingredient is barley, 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 tenth ingredient is fish meal, another protein-rich meat concentrate.

Fish meal is typically obtained from the “clean, dried, ground tissue of undecomposed whole fish and fish cuttings” of commercial fish operations.³

Unfortunately, this particular item is anonymous. Because various fish contain different types of fats, we would have preferred to have known the source species.

From here, the list goes on to include a number of other items.

But realistically, ingredients located this far down the list (other than nutritional supplements) are not likely to affect the overall rating of this Purina product.

With seven notable exceptions…

First, we find 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 failed to hatch.

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

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.⁴

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.

In addition, we note the inclusion of dried fermentation products in this recipe. Fermentation products are typically added as probiotics to aid with digestion.

We also find soybean oil in this recipe. This item is red flagged here only due to its rumored (yet unlikely) link to canine food allergies.

However, since soybean oil is high in omega-6 fatty acids and contains no omega-3’s, it’s considered less nutritious than flaxseed oil or a named animal fat.

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.

We also note the use of 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 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 Pro Plan Bright Mind Dog Food looks like an average dry product.

The dashboard displays a dry matter protein reading of 33%, a fat level of 16% and estimated carbohydrates of about 43%.

As a group, the brand features an average protein content of 33% and a mean fat level of 17%. Together, these figures suggest a carbohydrate content of 42% for the overall product line.

And a fat-to-protein ratio of about 51%.

Which means this Purina product line contains…

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

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

Our Rating of Purina Dog Food

Purina Pro Plan Bright Mind is a grain-inclusive dry dog food using a moderate amount of named by-product meal as its dominant source of animal protein, thus earning the brand 4.5 stars.

However, those concerned about the presence of menadione in this recipe may wish to ignore our rating and look elsewhere for a different product. Or consider using diet rotation to reduce the risks associated with feeding the same dog food… continuously, for a lifetime.
