Hill's Prescription Diet Hills Prescription Diet Gastrointestinal Biome Stew 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 Stew is a chicken stew under Hill's Prescription Diet label. Hill's aims it at dogs whose digestion is being managed on veterinary instruction.

Our view

Likely to suit

  • Dogs whose digestion is being managed on veterinary instruction
  • Prebiotic fibre chosen with the gut flora in mind, declared at 3.2%
  • A dog that needs coaxing through a rough patch: pork liver helps palatability
  • More water with each meal, at 78.5% moisture

Worth watching

  • Pork as well as chicken, worth raising if your vet picked a protein deliberately
  • Much of the list in category terms, so the full makeup is not spelled out
