Royal Canin vs Hill's: compare the actual recipes
Royal Canin Medium Adult scores C (65/100) under our current method. We do not name a winner against Hill’s until the exact Hill’s recipe has been identified. Sources checked on 8 September 2026.
Identify the product before comparing it
This review covers Royal Canin Medium Adult dry food, intended by its manufacturer for adult medium-breed dogs weighing 11-25 kg, from 12 months. Listed sizes are 4, 10 and 15 kg. Medium Adult 7+ and the wet recipes are separate products.
The historical PetFoodRate entry “Hill’s Medium Adult Optimal Care” and the merchant offer “Adult 1-6 Medium chicken” have different names. This check has not established recipe equivalence. The historical entry’s score must not be transferred to the current offer simply because the names look similar.
Royal Canin’s current declared recipe
The ingredient list starts with dehydrated poultry proteins, followed by wheat, maize flour, wheat flour and maize. It also lists hydrolysed animal proteins, animal fats and dehydrated pork proteins. Their individual percentages are not disclosed. Manufacturer label.
| Analytical constituent | Declared value |
|---|---|
| Crude protein | 25% |
| Fat | 14% |
| Crude ash | 6.3% |
| Crude fibre | 1.4% |
| Moisture | Not provided for this French formula |
The previous description “rice first, 14% chicken” does not describe this current label. We have also removed estimates of total meat and cereal percentages: the published information does not support those calculations.
What C (65/100) means
The recalculation uses the existing PetFoodRate method, without changing its rules. Component grades are C for proteins, C for nutrition, B for undesirables, D for transparency and B for species adaptability.
This is our classification-based score from declared information. It is not a clinical trial result or a grade for every Royal Canin product. The wording “dehydrated poultry proteins” alone does not establish that the ingredient is a by-product.
Check your exact Hill’s bag
Record its full name, age range, dog size, flavour, pack size and ingredient list. Compare the analytical constituents for that precise reference. A renamed product is not automatically the same formulation, and a score for another variant cannot settle the comparison.
For cost comparisons, use current bag prices and net weights. We do not maintain a price gap or daily saving estimate without verified prices and feeding quantities for both references.
