Hill's Prescription Diet Hills Prescription Diet Gastrointestinal Biome Mini 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.
Gastrointestinal Biome Mini is a chicken-led digestive care kibble in a small pellet. Hill's offers it in the Prescription Diet range for smaller dogs whose gut is being managed under veterinary supervision.
Gastrointestinal Biome Mini is a chicken-led digestive care kibble in a small pellet, fed to smaller dogs under a vet's supervision. We do not put a score on it. It is built around digestibility, so fibre runs high at 6.9% and the meat share is modest.
