Overview
Royal Canin's Size Health Nutrition line builds its formulas around a dog's breed size, and this Medium Adult recipe is tuned specifically for medium breed dogs rather than being a one size fits all food. The ingredient list includes brewers rice, chicken by-product meal, oat groats, wheat, corn gluten fat, and fish oil, with added EPA and DHA and L-lysine, aimed at supporting weight management, immune health, and skin and coat condition.
Because the recipe contains fish, oat, and wheat, it is worth checking those allergen notes if your dog has known sensitivities, since this is not a limited ingredient or allergen-free formula. At $61.99 for a 17 lb bag, it sits at a premium price point that reflects Royal Canin's veterinary nutrition positioning rather than a budget option.
Nearly 3,900 ratings at a 4.7 star average, along with roughly 3,000 units bought in the past month, point to a well established, frequently repurchased formula among medium breed owners.

Benefits
Maintains Immune Health, Ideal Weight, And Skin Health
The ingredient list, brewers rice, chicken by-product meal, oat groats, wheat, corn gluten fat, and fish oil, points to a formula built for digestibility and weight management rather than a grain-free or limited ingredient approach. Added EPA and DHA and L-lysine target skin, coat, and immune support, and the allergen notes for fish, oat, and wheat are worth checking against any known sensitivities your dog has.
What buyers say
A 4.7 star average across nearly 3,900 ratings, plus about 3,000 units bought in the past month, suggests medium breed owners who try this formula tend to stick with it.
Yes. It includes oat groats and wheat along with brewers rice, so it is not a grain-free formula. If your dog needs to avoid grains, this is not the right choice.
Is this only for medium breed dogs?
Yes, this recipe is part of Royal Canin's Size Health Nutrition line and is formulated specifically for medium breed adults. Royal Canin makes separate size specific formulas for small and large breeds.
