brewers rice
brewers rice 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.
Royal Canin
Royal Canin Shih Tzu Adult combines rice and brown rice with chicken by-product meal and chicken fat.
Alongside 22% protein, its 18% fat and 3,898 kcal/kg provide relatively dense energy, making it a candidate for active adult Shih Tzus or those eating small portions.
It relies more on fat for energy than on a high-protein profile. It is unsuitable for weight-prone dogs or chicken and wheat avoidance, and higher fat does not guarantee acceptance.

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 higher side for crude fat among extruded foods.
This food is on the higher side for calorie density among extruded foods. The same serving can provide more energy, so check portion guidance.
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.

brewers rice 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.
brown rice is a whole or coarse grain ingredient. It usually plays more of a carbohydrate and fiber role than a core protein role. It reads as an upper-tier carb and fiber 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.
Animal protein · chicken by-product meal (#3)
Plant protein · wheat gluten (#6)
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 3. brewers rice, brown rice supply carbohydrate energy. A carbohydrate source leads the list, a meaningful distinction when seeking a meat-led recipe.
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.
Among foods made the same way, protein is lower, fat is higher, and calorie density is higher. This combination provides more energy per gram. Compare it when smaller portions need to supply calories, and adjust grams first for a dog prone to weight gain. Higher calories do not establish a higher animal-protein share.
High calorie density 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.
