Royal Canin Anallergenic review

We don't put a score on this food. It is a veterinary diet, formulated for a diagnosed condition and meant to be fed on a vet's advice. Your vet has seen your dog and we have not, so a number from us could only pull you towards their advice or away from it, and neither of those is ours to do. What follows is what the label declares, what the analysis works out at, and where to buy it, with no judgement attached to any of it.

Anallergenic is the name Royal Canin gives this dry food. The maker puts it forward for food elimination trials and for long term feeding of dogs it describes as severely food sensitive.

DryAdultSenior

Royal Canin Anallergenic is a dry food the maker puts forward for food elimination trials and for long term feeding of severely food-sensitive dogs. We do not put a score on it. Its single protein source is a feather hydrolysate, broken into very short fragments, on a maize starch base.
