Hill's Prescription Diet Gastrointestinal Biome Wet Dog Food with Chicken 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.
Hill's places this in its Prescription Diet range as Gastrointestinal Biome, a chicken wet food the maker presents as fibre led feeding for dogs whose gut is being managed by a vet.
