Overview

A 24.2 pound bag of Royal Canin's veterinary hydrolyzed protein dry food, formulated with hydrolyzed soy protein at moderate calorie density for adult dogs with food sensitivities.

This is a veterinary diet, meaning it is formulated for use under a vet's guidance for dogs with diagnosed food sensitivities or skin issues linked to diet, rather than a general-purpose adult food. Hydrolyzing the soy protein breaks it into smaller fragments that are less likely to trigger an immune reaction, which is the basis for its use in elimination or sensitivity diets.

  • Hydrolyzed soy protein formula
  • Moderate calorie content
  • 24.2 pound bag
  • Veterinary diet for food sensitivities and skin support

Who it's for

Dogs diagnosed by a veterinarian with a food sensitivity or a diet-related skin condition, and already on or being started on a hydrolyzed protein diet, are the fit. It is not intended as a routine choice for dogs without a diagnosed sensitivity.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out
  • Hydrolyzed soy protein for reduced allergenic reactivity
  • Moderate calorie formula supports weight management
  • Large 24.2 pound bag reduces reorder frequency
  • Formulated for all breed sizes
What to check first
  • Intended for veterinary use, not a routine diet swap without a diagnosis
  • Large bag size is a poor fit if a trial diet does not suit the dog

Performance notes

The moderate calorie formulation targets weight management alongside the hydrolyzed protein's role in reducing sensitivity reactions, so it serves two purposes in one diet. As with any veterinary diet, effectiveness for a specific dog depends on that dog's actual sensitivity profile, which is why it is typically prescribed rather than chosen off the shelf.
