What’s actually in Royal Canin Yorkshire Terrier?
We analyzed Royal Canin Breed Health Nutrition Yorkshire Terrier Adult dry dog food. The top five ingredients are brewers rice (a beer-brewing by-product), brown rice, chicken by-product meal, chicken fat, and wheat gluten. Corn gluten meal and corn also appear in the formula, meaning three separate grain-derived fillers — wheat gluten, corn gluten meal, and corn — pad out the ingredient list alongside the two rice varieties.
The breed-specific elements include a small, specially shaped kibble designed for a Yorkie’s tiny jaw, GLA safflower oil for coat health, L-tyrosine for skin pigmentation, and omega-3 fatty acids from fish oil. Yorkshire Terriers have one of the longest, most demanding coats of any breed, so these coat-focused additions are genuinely relevant — layered on top of a formula that’s fundamentally grains and by-products.

The good stuff
GLA safflower oil is a standout inclusion for Yorkies. Gamma-linolenic acid supports the skin barrier and coat quality from the inside, which matters enormously for a breed whose floor-length silky coat is its defining feature. Fish oil provides EPA and DHA omega-3 fatty acids for additional coat luster and skin health. L-tyrosine supports skin pigmentation — a relevant addition for a breed whose coat color can fade.
Chelated minerals (zinc, manganese, copper proteinates) ensure better nutrient absorption in a tiny dog with a fast metabolism. Glucosamine and chondroitin support the joints and kneecaps in a breed highly susceptible to patellar luxation. Fructooligosaccharides serve as a prebiotic for the sensitive digestive system Yorkies are known for. Natural preservation with mixed tocopherols and rosemary extract avoids artificial preservatives like BHA/BHT.
The not-so-good stuff
Wheat gluten, corn gluten meal, and corn — three grain-derived fillers in a single formula. These are cheap protein boosters and binding agents that inflate the guaranteed analysis without delivering the amino acid profile of real animal protein. For a four-to-seven-pound dog that eats very little food per day, every bite needs to count, and grain fillers dilute the nutritional density.
Chicken by-product meal at position three is the only animal protein in the top five ingredients. By-product meal is a generic category — heads, feet, intestines — not the same as named chicken meal or whole chicken. Powdered cellulose (wood pulp) appears as a fiber filler with zero nutritional value. There are no whole meats anywhere in the formula, meaning your Yorkie never encounters actual chicken, beef, or fish — only processed meals and by-products.
How it compares
At C/58, Royal Canin Yorkshire Terrier outscores the standard Royal Canin (C/58) and ties the Royal Canin French Bulldog (C/58), but remains firmly average. The coat-support supplements give it a slight edge over the other breed-specific formulas, though the underlying grain-and-by-product pattern is identical across the line.
For Yorkshire Terriers specifically, Wellness Complete Health (B/82) delivers deboned chicken as the first ingredient with salmon oil for coat support — a dramatically better protein foundation for a small breed. Nutro (B/77) offers chicken, brown rice, and whole grains without the gluten fillers, plus omega fatty acids for coat health. Either option provides better base nutrition while addressing the same Yorkie-specific concerns.

The bottom line
Royal Canin Yorkshire Terrier earns a C grade (58/100) from KibbleIQ. The GLA safflower oil, fish oil, L-tyrosine, and joint supplements are genuinely relevant for a breed with a demanding coat, fragile kneecaps, and sensitive digestion. But the formula builds those supplements on top of brewers rice, by-product meal, wheat gluten, corn gluten meal, and powdered cellulose — ingredients that don’t belong in a premium breed-specific food. Your Yorkie will get better nutrition from Wellness Complete Health (B/82) or Nutro (B/77) paired with a fish oil supplement for that famous silky coat. Shop on Amazon →
