Corn
Corn is a refined carbohydrate source. It usually reads as a starch and energy source rather than a protein driver. It reads as an mid-tier carb source.
Royal Canin
Royal Canin Large Comfort Care starts with chicken by-product meal, brewers rice, and corn, with moderate-low fat and glucosamine disclosed.
I would use it as a calmer large-dog daily food, not for high-protein or fresh-meat-led goals.

01. NUTRIENT PROFILE
Compare protein, fat and energy density in low, typical and high bands.
This food is on the lower side for crude protein among extruded foods.
This food is on the lower side for crude fat among extruded foods.
This food sits around the typical calorie range among extruded foods. Check the feeding guide and weight trend alongside this comparison.
Undisclosed values are not treated as zero.
02. INGREDIENT QUALITY & DISCLOSURE
The analysis uses the registered ingredients. Complete-panel coverage is not verified, so an unlisted ingredient cannot be assumed absent.
Read the listed ingredients below. Complete-panel coverage is not verified here; do not infer that an unlisted ingredient is absent.

Corn is a refined carbohydrate source. It usually reads as a starch and energy source rather than a protein driver. It reads as an mid-tier carb source.
chicken by-product meal is a by-product meal. It can still contribute protein, but the primary-ingredient read should stay conservative. It reads as an bottom-tier protein source.
brewers rice flour is a refined carbohydrate source. It usually reads as a starch and energy source rather than a protein driver. It reads as an lower-tier carb source.
Animal protein · chicken by-product meal (#2), dried fish protein digest (#17)
Plant protein · corn gluten meal (#4), wheat gluten (#10)
Animal-based does not always mean clearly sourced.
Unspecified animal protein is read conservatively.
03. CHOOSING FOR YOUR DOG
chicken by-product meal supply animal protein, starting at ingredient 2. Corn, brewers rice flour supply carbohydrate energy. A carbohydrate source leads the list, a meaningful distinction when seeking a meat-led recipe.
corn gluten meal, wheat gluten supplement plant protein further down the list, after the first three ingredients. The crude-protein figure includes both animal and plant contributions. chicken fat add fat and energy; fat content is a separate choice criterion from the protein sources.
Across the registered ingredients, multiple protein sources appear, including chicken, unspecified. Some protein sources are not fully identified, which limits choices that require excluding a specific protein.
Among foods made the same way, protein is lower, fat is lower, and calorie density is typical. Calorie density alone does not separate this into an active-dog or weight-management food. Consider protein exclusions and fat, then set portions for the dog’s weight and activity.
Plant-protein concentration remains the clearest trade-off here.
04. COMPARE FOODS
Exact protein-type matches come first, then close protein-family matches fill the comparison.
05. MANUFACTURING & DISCLOSURE
Founded in 1968 in France.
There is a usable disclosure baseline, but the public record is still fairly thin.
This brand has a confirmed public recall history, with a recent 2023 mislabeling case in public sources.
