Hill's Prescription Diet i/d Stress Mini Dog Food 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.

i/d Stress Mini is a small bite kibble built around chicken and Hill's own ActivBiome+ blend, sold in the Prescription Diet range. Hill's puts it forward for little dogs whose digestive upsets it links to stress.

DryAdult

A veterinary diet for small dogs, so it carries no score from us. Hill's links the digestive upsets it is aimed at to stress. Fat is held low at 8.8% of dry matter, with starch carrying the energy, which is how a digestive kibble of this kind is built.

Our view

Likely to suit

  • Small dogs fed on a vet's advice for digestive upsets
  • A low-fat build, at 8.8% of dry matter
  • Prebiotic fibre declared as a blend at 7.5%, from beet pulp, flaxseed, pecan shell, citrus and cranberry

Worth watching

  • Chicken, turkey, fish and dairy on the label, with category entries that could carry more
  • No moisture declared, so the dry-matter figures assume a standard 8%
