Hill's Prescription Diet r/d 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.
In the Hill's Prescription Diet range this is r/d, a chicken-based dry diet. The maker offers it for weight reduction in dogs whose slimming is being supervised by a vet.

Our view
Likely to suit

- Owners who want a fibre-led bowl: crude fibre is declared at 12.2%
- Dogs of every size, with feeding set out by bodyweight from 1kg to 50kg
- A printed trace mineral panel, each entry dosed
Worth watching
- Category wording near the top, so the label cannot be read as an exclusion list
- Chicken is the only animal named, at 12% inside meat and animal derivatives
