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.

Our view

Likely to suit

  • Adult dogs whose vet has recommended a fibre led gut diet
  • Owners who want the prebiotic blend itemised, from pecan shell to cranberry
  • A fibre level written in on purpose: 7.3% of dry matter
  • Any size, with the label's table running from a 1kg dog to a 50kg one

Worth watching

  • Chicken, pork and fish all on the list, under an opening line that names none of them
  • Cereals, oils and fats given only as headings
