Pro Plan Veterinary Diet Dermatosis 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.
Purina sells this one through Pro Plan Veterinary Diets as Dermatosis, a herring-based dry diet the brand formulates for dogs whose skin problems a vet is managing.
Purina's herring-based dry diet for dogs whose skin problems a vet is managing, fed on a vet's advice. We do not put a score on it. The list runs to nine entries, which is the point on a diet of this kind.
Our view
Likely to suit
- Dogs on a vet-directed skin plan
- Owners keeping a food diary, with only nine entries to track
- Dogs kept off dairy and poultry
Worth watching
- Digest names no animal, and pork fat adds a further species
- Corn starch and rapeseed, if either has come up for your dog before
Written by our editorial team. Independent guidance, not veterinary advice.
