|Estimated Nutrient Content|

|Calorie Weighted Basis||25%||37%||39%|
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 brown rice, a complex carbohydrate that (once cooked) can be fairly easy to digest. However, aside from its natural energy content, rice is of only modest nutritional value to a dog.
The third 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 prime cuts have been removed.
In addition to organs (the nourishing part), this stuff can contain almost anything — feet, beaks, undeveloped eggs — anything except quality skeletal muscle (conventional meat).
On the brighter side, by-product meals are meat concentrates and contain nearly 300% more protein than fresh chicken.
In any case, although this item contains all the amino acids a dog needs, we consider chicken by-products an inexpensive, lower quality ingredient.
The fourth 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 fifth ingredient is wheat gluten. Gluten is the rubbery residue remaining once wheat has had most of its starchy carbohydrate washed out of it.
Compared to meat, glutens are inferior plant-based proteins low in some 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 sixth ingredient is corn gluten meal, another plant-based protein booster.
The seventh ingredient includes 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.
After the natural flavor, we find powdered cellulose, a non-digestible plant fiber usually made from the by-products of vegetable processing. Except for the usual benefits of fiber, powdered cellulose provides no nutritional value to a dog.
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, 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.
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, we note the inclusion of vegetable oil, 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, 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 also 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.
Royal Canin Breed-Specific Adult Dog Food
The Bottom Line
Judging by its ingredients alone, Royal Canin Breed-Specific Adult looks like a below-average dry dog food.
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.
As a group, the brand features an average protein content of 28% and a mean fat level of 15%. Together, these figures suggest a carbohydrate content of 49% for the overall product line.
And a fat-to-protein ratio of about 56%.
Near-average protein. Near-average fat. And near-average carbs when compared to a typical dry dog food.
When you consider the protein-boosting effect of the wheat gluten and corn gluten meal, this looks like the profile of a kibble containing a below-average amount of meat.
Royal Canin Breed-Specific Adult is a plant-based dry dog food using a below-average amount of chicken by-product meal as its main source of animal protein, thus earning the brand 2.5 stars.
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.
