Purina Pro Plan Sensitive Skin & Stomach (salmon & rice) is the formula most veterinary dermatology conversations eventually reach, because it pairs a single novel-leaning animal protein (salmon) with easily digested rice and a guaranteed omega-3 level that shows up on the label, not just in marketing copy.
| Item | Detail |
|---|---|
| First ingredient | Salmon (fresh), followed by salmon meal |
| Protein / Fat | 26% protein, 16% fat (adult formula) |
| Key skin nutrients | Guaranteed omega-3 from fish oil; vitamin A and zinc |
| Grain status | Grain-inclusive (rice, oat meal, barley) |
| Typical street price | $62–78 for a 30 lb bag (about $2.10–2.60/day for a 40 lb dog) |
Why dermatologists keep recommending it
Skin and stomach trouble usually share one root: chronic inflammation aggravated by ingredients the dog digests poorly. This formula solves for both at once. Salmon supplies EPA and DHA at levels that measurably reduce itching within 6–8 weeks in many dogs, while the absence of chicken, corn, and wheat removes the three most common triggers. Purina also publishes feeding-trial results behind the line, which most competitors cannot claim.
Where it falls short
The formula is not hypoallergenic in the strict veterinary sense — it still contains animal fats of mixed origin, so dogs with confirmed food allergies may still react. Pea protein appears mid-list, adding plant protein that inflates the crude-protein number without matching meat quality. Owners wanting a true limited-ingredient diet should read our comparison files before settling. Calorie density is moderate (3,930 kcal/kg), so large active dogs eat through a 30 lb bag in under three weeks.
FAQ
Is this formula good for dogs with itchy skin?
It is one of the most evidence-backed retail options for mild itching. Fish-oil omega-3s are the active ingredient; if a dog shows no improvement in 8 weeks, a veterinary elimination diet is the next step.
Does it contain chicken?
No whole chicken or chicken meal in the salmon formula, but it does contain poultry fat in some regional batches, so true chicken-allergic dogs should verify the current bag.
