The first ingredient in this dog food is corn. Corn is an inexpensive and controversial cereal grain of only modest nutritional value to a dog.

For this reason, we do not consider corn a preferred component in any dog food.

The second ingredient is wheat. Wheat is another cereal grain and subject to the same issues as corn (previously discussed).

The third ingredient is meat and bone meal, a dry “rendered product from mammal tissues, including bone, exclusive of 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. It doesn’t even specify the source animal.

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

The fourth ingredient is corn gluten meal. Gluten is the rubbery residue remaining once corn has had most of its starchy carbohydrate washed out of it.

Compared to meat, glutens are inferior grain-based proteins lower in many of the essential amino acids dogs need for life.

This inexpensive plant-based ingredient can significantly 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 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: restaurant grease, slaughterhouse waste, diseased cattle — even (although not likely) euthanized pets.

We do not consider generic animal fat a quality ingredient.

The sixth ingredient is soybean meal. Soybean meal is relatively useful by-product — what remains of soybeans after all the oil has been removed.

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 seventh ingredient is lamb meal. Lamb meal is considered a meat concentrate and contains nearly 300% more protein than fresh lamb.

The eighth 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.

By the way, contrary to popular belief, brewers rice has nothing to do with the process of brewing beer.

The ninth ingredient lists the controversial food moisturizer, propylene glycol. Propylene glycol has been banned by the FDA for use in making cat food.

But it can still be found in some lower quality dog foods.

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 seven notable exceptions

First, we’re always disappointed to find artificial coloring in any dog food. Coloring is used to make the product more appealing to you, not your dog. After all, do you really think your dog cares what color his kibble is?

Next, garlic oil may be a controversial item. We say “may be” here because we are not certain of the oil’s chemical relationship to raw garlic itself.

Although most experts favor the ingredient for its numerous health benefits, garlic (in rare cases) has been linked to Heinz body anemia in dogs.3

However, the limited professional literature we surveyed provided no definitive warnings regarding the use of garlic — especially when used in small amounts (as it likely is here).

In addition, this food contains animal digest. Animal digest is a chemically hydrolyzed mixture of animal by-products that is typically sprayed onto the surface of a dry kibble to improve its taste.

Sugar is always an unwelcome addition to any dog food. Because of its high glycemic index, it can unfavorably impact the blood glucose level of any animal soon after it is eaten.

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

Additionally, the minerals listed here do not appear to be chelated. And that can make them more difficult to absorb. Non-chelated minerals are usually associated with lower quality dog foods.

And lastly,this recipe 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 either of its dog food nutrient profiles, we question the use of this substance in any canine formulation.

Purina Healthy Morsels Dog Food
The Bottom Line

Judging by its ingredients alone, Purina Healthy Morsels Dog Food looks like a below-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 24%, a fat level of 13% and estimated carbohydrates of about 55%.

And a fat-to-protein ratio of about 52%.

Below-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 a limited amount of meat.

Bottom line?

Purina Healthy Morsels is a plant-based dry dog food using a limited amount of unspecified meat and bone meal as its main source of animal protein, thus earning the brand 1 star.

Not recommended.
