What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, Purina ONE +Plus Skin & Coat occupies an interesting middle ground: high-trust threads on r/dogs and r/DogFood repeatedly describe owners switching down from Pro Plan and seeing no real-world difference for significantly less money. One r/dogs commenter explicitly preferred Purina ONE Skin & Coat over Pro Plan after their dog responded better to it. The conflicting signal is meaningful: dogfoodadvisor.com gives the Purina ONE +Plus line only a 3-star rating — below their score for Pro Plan — and a r/DogFood thread raised legitimate concerns about caloric density (over 500 calories per cup) that could matter for less-active dogs prone to weight gain.
What reviewers liked
- High-trust r/dogs and r/DogFood threads describe it as nearly equivalent to Pro Plan at lower cost
- Salmon-first formula targets skin and coat issues
- Strong verified-purchase signals across Walmart, Chewy, and Petco
- Senior owners on r/DogFood specifically praise the Vibrant Maturity variant within the line
- Widely available at grocery and big-box stores, not just pet specialty retailers
Where it falls short
- dogfoodadvisor.com rates the +Plus line only 3 stars — below Purina Pro Plan
- A r/DogFood commenter flagged caloric density (500+ cal/cup) as too high for less-active dogs
- Not a true clinical sensitivity formulation — dogs with severe issues may still need Pro Plan or Hill's
- Some Chewy reviewers report dogs preferring Pro Plan's palatability
- Skin & coat marketing claims are looser than the specialty-formulated competitors

We surface this disagreement rather than paper over it.
At roughly $50 for 31 lb, it's priced almost identically to IAMS while targeting skin and coat specifically. Specialist communities generally treat it as the smart-money pick if your dog doesn't have a diagnosed sensitivity requiring a true veterinary formulation.
