Hill's Prescription Diet

Hill's Prescription Diet k/d Early Stage 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.

k/d Early Stage is the Prescription Diet kidney food for dogs at the early part of a renal diagnosis. It is built around a held-back protein level and Hill's own prebiotic blend.

DryAdult

The Prescription Diet kidney food for dogs at the early part of a renal diagnosis, fed on a vet's advice, so we put no score on it. It is built around a held-back protein level, with egg and pea protein doing the protein work and fat carrying the energy. Hill's own prebiotic blend is declared at 1.1%.

Our view

Likely to suit

  • Dogs whose vet has diagnosed early-stage kidney disease and recommended this food
  • A reduced protein plan, with protein declared at 17.4%
  • Owners who want the protein sources named: dried whole eggs and pea protein
  • A trace element panel printed with doses attached

Worth watching

  • Meat and animal derivatives with no species named
  • Fish oil at 1.8% and egg high on the list, both to account for on an exclusion plan
