The first ingredient in this dog food is lamb. Although it is a quality item, raw lamb 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 includes 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 oat flour. Since oat flour is nothing more than finely ground oats, it provides about the same gluten-free nutritional content as raw oats.

The fourth ingredient is sorghum. Sorghum (milo) is a starchy cereal grain with a nutrient profile similar to corn.

Since it is gluten-free and boasts a smoother blood sugar behavior than other grains, sorghum may be considered an acceptable non-meat ingredient.

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

The sixth 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 seventh ingredient includes 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.1

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

What’s more, the controversial chemical ethoxyquin is frequently used as a preservative in fish meals.

But because it’s usually added to the raw fish before processing, the chemical does not have to be reported to consumers.

We find no public assurances from the company this product is ethoxyquin-free.

Without knowing more, we would expect to find at least a trace of ethoxyquin in this product.

The eighth ingredient is chicken fat. Chicken fat is obtained from rendering chicken, a process similar to making soup in which the fat itself is skimmed from the surface of the liquid.

Chicken fat is high in linoleic acid, an omega-6 fatty acid essential for life. Although it doesn’t sound very appetizing, chicken fat is actually a quality ingredient.

The ninth 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 tenth ingredient is beet pulp. Beet pulp is a controversial ingredient, a high fiber by-product of sugar beet processing.

Some denounce beet pulp as an inexpensive filler while others cite its outstanding intestinal health and blood sugar benefits.

We only call your attention here to the controversy and believe the inclusion of beet pulp in reasonable amounts in most dog foods is entirely acceptable.

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 note the inclusion of sodium hexametaphosphate, a man-made industrial polymer with no known nutritive value.

HMP is used in making soap, detergents, water treatment, metal finishing and most likely here to decrease tartar build-up on the teeth.

Although some might disagree, we’re of the opinion that food is not the place for tartar control chemicals or any other non-nutritive substances.

Next, this recipe contains fructooligosaccharide, an alternative sweetener2 probably used here as a prebiotic. Prebiotics function to support the growth of healthy bacteria in the large intestine.

In addition, flaxseed meal is one of the best plant-based sources of healthy omega-3 fatty acids. Flax meal is particularly rich in soluble fiber.

However, flaxseed contains about 19% protein, a factor that must be considered when judging the actual meat content of this dog food.

Next, 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.

And lastly, 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.

Eukanuba Natural Lamb and Rice Formula Dog Food
The Bottom Line

Judging by its ingredients alone, Eukanuba Natural Lamb and Rice Formula dog food 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 26%, a fat level of 16% and estimated carbohydrates of about 51%.

As a group, the brand features an average protein content of 26% and a mean fat level of 14%. Together, these figures suggest a carbohydrate content of 52% for the overall product line.

And a fat-to-protein ratio of about 53%.

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

When you consider the protein-boosting effects of the flax meal and brewers dried yeast, this looks like the profile of a kibble containing a below average amount of meat.

Bottom line?

Eukanuba Natural Lamb and Rice Formula is a plant-based dry dog food using a below-average amount of lamb as its main source of animal protein, thus earning the brand 3.5 stars.

Recommended.
