Hill's Prescription Diet r/d Weight Reduction 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.

r/d Weight Reduction is a wet food, and Hill's carries it in the Prescription Diet range. The maker intends it for dogs losing weight to a plan their vet has set.

WetAdult

A wet weight-reduction diet from the Hill's Prescription Diet range, meant for dogs losing weight to a plan their vet has set. The build is the standard one for a reducing food: fat at 8.8% of dry matter and fibre at 13.6%. Energy is 81 kcal per 100g.

Our view

Likely to suit

  • Dogs on a vet-set weight-loss plan
  • A full-looking bowl on few calories, since the food is so dilute
  • Owners who want calcium declared, here at 0.88% of dry matter
  • Adults of any size, as the range lists them

Worth watching

  • No ingredient names an animal apart from the eggs, so the list cannot settle an exclusion trial
  • Umbrella terms mean the mix behind them can move with supply
