Royal Canin leads on brand trust and sensitivity risk, but in our view Hill's takes it overall on a stronger nutrition profile and far better value, since Royal Canin's large-breed formula is among the priciest per 1,000 kcal we score.
This verdict is our opinion under the PetScored rubric, not veterinary advice. The exact sub-scores are in the table below; each food’s source confidence and limitations stay on its own scorecard.

Royal Canin
Large Breed Adult
Built around size-specific formulation and a strong research pedigree. The main drawback is a premium price for a formula that still leans heavily on by-products and grains.

Hill's Science Diet
Adult Large Breed Chicken & Barley
A feeding-trial-substantiated large-breed maintenance kibble with chicken first and a grain-forward base (barley, brown rice, wheat, corn). Strong brand-trust record; the corn and soy fractions and a 20% protein floor are the tradeoffs.
