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 chicken by-product meal, a dry rendered product of slaughterhouse waste. It’s made from what’s left of a slaughtered chicken after all the choice 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 chicken.

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

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 wheat gluten. Gluten is the rubbery residue remaining once wheat has had most of its starchy carbohydrate washed out of it.

Although wheat gluten contains 80% protein, this ingredient would be expected to have a lower biological value than meat.

The fifth 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 wheat gluten and corn gluten meal can notably boost the total protein reported on the label — factors that must be considered when judging the actual meat content of this dog food.

The sixth 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.

After the natural flavor, we find 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 four notable exceptions

First, vegetable oil is a generic oil of unknown origin. The ratio of omega-6 to omega-3 fats in any oil is nutritionally critical and can vary significantly (depending on the source).

Without knowing more, it’s impossible to judge the quality of an item so vaguely described. However, compared to a named animal fat, a generic vegetable oil cannot be considered a quality ingredient.

Next, we find grain distillers dried yeast, a by-product resulting from the fermentation of grains separated from distilling mash as a by-product of the production of ethanol (biofuel).

Even though it contains over 40% 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.

In addition, this recipe contains fructooligosaccharide, an alternative sweetener1 probably used here as a prebiotic. Prebiotics function to support the growth of healthy bacteria in the large intestine.

And lastly, this food includes 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.

Royal Canin Giant Dog Food
The Bottom Line

Judging by its ingredients alone, Royal Canin Giant 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 32%, a fat level of 16% and estimated carbohydrates of about 44%.

As a group, the brand features an average protein content of 32% and a mean fat level of 16%. Together, these figures suggest a carbohydrate content of 44% for the overall product line.

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

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 wheat gluten, corn gluten meal and grain distillers dried yeast, this looks like the profile of a dry product containing just a moderate amount of meat.

Bottom line?

Royal Canin Giant is a plant-based dry dog food using a moderate amount of named by-product 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.
