Hill's Prescription Diet

Hill's Prescription Diet l/d Dry 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.

l/d is the dry liver diet in Hill's Prescription Diet range, built around plant protein sources and a lowered protein level. The maker aims it at dogs whose liver condition is being managed under veterinary care.

DryAdult

Hill's dry liver diet, built on plant protein at a lowered level for dogs whose liver condition is managed by a vet. Fat comes second on the list and energy reaches 407 kcal per 100g, so a smaller bowl carries the calories. We do not score veterinary diets, so this page sets out the label and leaves the judgement to your vet.

Our view

Likely to suit

  • Dogs whose vet is managing a liver condition and has prescribed l/d
  • A smaller bowl that still holds condition, fat at 23.8% of dry matter
  • Owners who want the protein sources named: soybean meal, dried whole eggs and maize gluten meal

Worth watching

  • Category wording at the top of the list, with no animal species named anywhere
  • No copper figure printed on the additive declaration

Written by our editorial team. Independent guidance, not veterinary advice.

What's in it
  • CerealsFirst on the list.
  • Oils and fatsHigh placing for a fat, and where much of the energy comes from.
  • Vegetable protein extractsSoybean meal and maize gluten meal, by Hill's own naming.
  • Eggs and egg derivativesDried whole eggs, the animal side of the protein.
  • Seeds, minerals
  • Meat and animal derivativesNo species identified.
  • Derivatives of vegetable origin

Iron, iodine, manganese, zinc at 136mg and selenium, with a natural antioxidant; no copper figure is printed.

Soya, maize and egg are named; anything else could sit inside the category terms, so an exclusion plan needs the practice's view.
