Rating: ☆☆☆☆☆

Purina Pro Plan Veterinary Diets EN Gastroenteric Canine Dog Food is not rated due to its intentional therapeutic design.

The Purina Pro Plan Veterinary Diets EN Gastroenteric product line includes four dry dog foods, each designed to help in the treatment of digestive issues.

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.

Important: Because many websites do not reliably specify which Growth or All Life Stages recipes are safe for large breed puppies, we do not include that data in this report. Be sure to check actual packaging for that information.

Protein = 24% | Fat = 27% | Carbs = 50%

The first ingredient in this dog food 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 second 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 third 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 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 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 sixth ingredient is coconut oil, a natural oil rich in medium-chain fatty acids.

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) and chronic skin disorders, MCT can be considered a positive addition to this recipe.

The seventh ingredient is dicalcium phosphate, likely used here as a dietary calcium supplement.

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 six notable exceptions

First, we find wheat bran. Wheat bran is made from the tough outer layer of a wheat kernel. Brans are especially rich in dietary fiber, protein, vitamins and minerals.

Next, soybean oil 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.

In addition, garlic 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.

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

In addition, this food 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 recipe 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.

EN Gastroenteric Dog Food
The Bottom Line

Although this is a prescription product, our review has nothing to do with the accuracy of claims made by the manufacturer as to the product’s ability to treat or cure a specific health condition.

So, to find out whether or not this dog food is appropriate for your particular pet, it’s important to consult your veterinarian.

With that understanding…

Judging by its ingredients alone, Purina Pro Plan Veterinary Diets EN Gastroenteric looks like a below-average dry product.

But ingredient quality by itself cannot tell the whole story. We still prefer to estimate the product’s meat content before concluding our report.

The dashboard displays a dry matter protein reading of 26%, a fat level of 12% and estimated carbohydrates of about 54%.

As a group, the brand features an average protein content of 26% and a mean fat level of 10%. Together, these figures suggest a carbohydrate content of 57% for the overall product line.

And a fat-to-protein ratio of about 39%.

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 meal in this recipe, and the potato and pea proteins contained in others, this looks like the profile of a kibble containing just a moderate amount of meat.

Bottom line?

Purina Pro Plan Veterinary Diets EN Gastroenteric is a plant-based dry dog food using a moderate amount of named meat and by-product meals as its main sources of animal protein.
