Hill's Prescription Diet z/d Mini Food Sensitivities Dry Dog Food Original Bag 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.

z/d Mini is the small-kibble version of Hill's hydrolysed food sensitivities diet, sold in the Prescription Diet range for little dogs and fed on a vet's say-so.

DryAdult

The small-kibble version of Hill's hydrolysed food sensitivities diet, from the Prescription Diet range; we do not score veterinary diets. The protein source is chicken liver hydrolysate, printed at 26% of the bag, and maize starch carries the carbohydrate.

Our view

Likely to suit

  • Small adult dogs whose vet has prescribed a hydrolysed diet
  • Owners who want to know how much of the bag the hydrolysed protein makes up
  • Little mouths, with a small kibble and a feeding guide that stops at 15kg
  • Every added mineral printed with a dose

Worth watching

  • Fish oil at 0.9% sits beside the chicken hydrolysate, so a strict one-protein trial has two animal sources to account for
  • No moisture declared, so the dry matter figures assume 8%

The details

Dog fit

Listed for small adult dogs on a vet's advice. The guide runs from 30 grams a day at 1kg to 245 grams at 15kg, and the vet settles where your dog sits.
