The scores
Blue Buffalo Life Protection Adult: B (78/100) — Above average. Deboned chicken and chicken meal lead the formula, backed by whole grains (brown rice, oatmeal, barley), flaxseed for omega-3s, and a LifeSource Bits antioxidant blend.
Royal Canin French Bulldog Adult: C (58/100) — Mid-C. Brewers rice first, wheat second, chicken by-product meal third, wheat gluten at #5. Breed-specific supplements (glucosamine, L-tyrosine, omega-3s, FOS prebiotics) lift the score into C territory, but the wheat-heavy base is a concerning choice for the breed.
A 20-point gap that crosses a full letter grade. Blue Buffalo sits in solid B territory among mid-premium mainstream brands. Royal Canin French Bulldog sits in mid-C, propped up by breed-specific supplements rather than quality base ingredients.
How the ingredients compare
The top five ingredients tell the story:
Blue Buffalo: Deboned Chicken, Chicken Meal, Brown Rice, Oatmeal, Barley
Royal Canin French Bulldog: Brewers Rice, Wheat, Chicken By-Product Meal, Chicken Fat, Wheat Gluten
Blue Buffalo leads with two named animal protein sources — deboned chicken (fresh whole meat) and chicken meal (concentrated rendered protein). The three grains that follow are all whole grains with genuine nutritional value. No corn, no wheat, no soy, no by-products in the top five.
Royal Canin French Bulldog leads with brewers rice — a processed grain by-product from beer brewing. Position two is wheat, one of the most common food allergens in dogs and particularly concerning for French Bulldogs, which are among the most allergy-prone breeds. Chicken by-product meal at position three is the primary animal protein source, but it’s a generic rendered by-product (heads, feet, intestines) rather than clean muscle meat. Chicken fat at #4 provides calories. Wheat gluten at #5 doubles down on wheat — it’s a concentrated plant protein that inflates the guaranteed-analysis protein percentage.
For an allergy-prone breed, leading with wheat and doubling down with wheat gluten is the defining problem with this formula. Frenchies commonly develop wheat sensitivities, and a breed-specific food for this breed putting wheat as the second ingredient is hard to defend nutritionally.
Where Blue Buffalo pulls ahead
Real animal protein foundation. Two named chicken sources in the first two positions — deboned chicken and chicken meal — versus a by-product meal buried behind brewers rice and wheat. This is the single biggest differentiator and the primary reason for the 20-point gap. Blue Buffalo’s protein comes from clean muscle meat and concentrated meal; Royal Canin’s comes from rendered by-products.
Wheat-free formulation. For French Bulldogs specifically, this is a major advantage. Wheat allergies and sensitivities are among the most common food issues in the breed, manifesting as itchy skin, ear infections, digestive upset, and chronic paw licking. Blue Buffalo contains no wheat anywhere in the formula. Royal Canin French Bulldog puts wheat at #2 and wheat gluten at #5 — a combination that’s essentially contradictory for the breed it targets.
Quality whole grains. Brown rice, oatmeal, and barley are whole grains with genuine nutritional value — fiber, B vitamins, and slow-digesting carbohydrates. Royal Canin uses brewers rice (a processing by-product) as its primary grain source, which delivers empty carbohydrate calories without the whole-grain benefits.
LifeSource Bits antioxidant blend. Blue Buffalo includes small, dark-colored pieces of vitamin- and antioxidant-rich ingredients that aren’t subjected to the high-heat extrusion process used for the main kibble. This preserves heat-sensitive nutrients like vitamin C and certain B vitamins. Royal Canin uses a standard synthetic vitamin and mineral premix without this cold-processing step.
Lower price. Despite scoring 20 points higher, Blue Buffalo Life Protection typically costs less per pound than Royal Canin French Bulldog’s breed-specific formula. You get better ingredients and pay less for them. Shop on Amazon →
Where Royal Canin holds its own
Breed-specific kibble shape. This is Royal Canin’s genuine advantage. The kibble is designed as a flat, pillow-shaped piece specifically for French Bulldogs’ brachycephalic (flat-faced) jaw structure. Frenchies often struggle to pick up and chew standard round kibble, and the targeted shape is a real quality-of-life feature. Blue Buffalo’s general-purpose kibble shape doesn’t address this.
L-tyrosine for skin pigmentation. Royal Canin includes L-tyrosine, an amino acid that supports skin and coat pigmentation. Frenchies commonly have pigmentation issues on their noses, paws, and belly skin, and targeted amino acid supplementation is a thoughtful breed-specific addition.
FOS prebiotics for sensitive digestion. Fructooligosaccharides feed beneficial gut bacteria and support digestive health. French Bulldogs are notoriously prone to gas, loose stools, and sensitive stomachs — FOS addresses this directly. Blue Buffalo doesn’t include FOS in its standard formula.
Glucosamine and EPA/DHA. Royal Canin includes glucosamine hydrochloride for joint support (Frenchies are prone to intervertebral disc disease and hip dysplasia) and fish oil for skin-supporting omega-3 fatty acids. These are genuinely relevant breed-specific additions, though their benefit is layered on top of a weak base formula. Shop on Amazon →
The bottom line
Blue Buffalo Life Protection (B/78) wins decisively over Royal Canin French Bulldog (C/58) by 20 points and a full letter grade. The combination of real animal protein first, wheat-free formulation, and quality whole grains makes Blue Buffalo the clearly better choice for Frenchie owners — especially given the breed’s allergy-prone nature.
Royal Canin’s breed-specific additions (kibble shape, L-tyrosine, FOS, glucosamine) are thoughtful, and the kibble shape is a real functional advantage for flat-faced dogs. But layering breed-targeted supplements on top of a wheat-heavy, by-product-based formula doesn’t overcome the fundamental ingredient quality gap. If your Frenchie has sensitivities (many do), wheat at position #2 is working against you, not for you.
For French Bulldogs with confirmed food sensitivities, consider Blue Buffalo Basics (B/78) for a cleaner limited-ingredient option, or Canidae (B/77) for a multi-protein approach. Read our full reviews of Royal Canin French Bulldog and Blue Buffalo for the complete breakdown.
