Hill's Prescription Diet i/d Low Fat 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.

The kibble is i/d Low Fat, a chicken based recipe built on broken rice with the fat level pulled back. Hill's sells it inside the Prescription Diet range for dogs the maker says need fat restricted while their digestion is treated.

DryAdult

Hill's i/d Low Fat is a chicken based kibble on broken rice, sold for dogs the maker says need fat restricted while their digestion is treated. It is fed on a vet's advice and we do not score it. Fat converts to 8.9% of dry matter, which is the name of the food doing what it says.

Our view

Likely to suit

  • Adult dogs whose vet has recommended a low-fat digestive diet
  • Owners who want the prebiotic blend itemised, at 7.5%
  • Every size, from a 1kg dog upwards on the bag's guide
  • A mineral panel printed dose by dose

Worth watching

  • Chicken and turkey in a single meal entry
  • Category wording for most of the list, which will not clear a strict avoidance plan
  • Portion and duration are the vet's call
