Our verdict

Is Diamond Pet Foods Skin & Coat All Life Stages Dog Salmon & Potato Formula a good dog food?

We score it 49/100 (Average). This reflects the ingredient quality, composition and label transparency of the recipe as declared on the label.

How we score

Only part of the analytical constituents are declared, so the nutritional picture is incomplete.

100% of this recipe has no printed percentage. Estimated shares are model estimates, not label facts.

Why you might choose it

  • Single named animal protein: fish.
  • Doesn't list grain ingredients.
  • Declares energy content, which most labels omit.

Why you might not

  • Meat makes up an estimated 4% of the dry matter (5% as fed); carbohydrates dominate.
  • 100% of the recipe mass has no printed percentage, so the exact split cannot be verified.

Who is this food for?

Suits

  • Labelled by the manufacturer for all lifestages
  • Grain-free: no grain ingredients listed
  • Single named protein: fish
  • Doesn't list chicken, beef, turkey, lamb, venison, pork, duck as ingredients

These points are derived from declared ingredients and analysis, not a substitute for veterinary advice. If your dog has a diagnosed condition, food choice is a medical nutrition decision: speak to your vet. Find foods that fit your dog.

Contributions are rounded to two decimals, so they may not sum exactly to the subtotal. The full coefficient table is published on the methodology page.

Nutritional: declared analysis vs reference ranges

How the declared analysis compares with FEDIAF reference ranges for adult dogs. The label prints as-fed values; we convert to a dry-matter basis before scoring, and the bands are dry-matter ranges. Scores rise to 100 at the band midpoint: the reference is adequacy, not maximisation. Nutrients with a published upper limit taper again above it; fat is policed through calorie density rather than a direct penalty.

Guaranteed-analysis FEDIAF score: crude minimums and maximums are bounds, not typical values; moisture (a maximum) uses the processing median where available; experimental US score.

NutrientAs fed (label)Dry matter (scored)Score

Omega fatty acids (omega-6 and omega-3): scored as the mean of its declared components (omega-6 100). The FEDIAF minimum for omega-6 is linoleic acid specifically.

Scored over 5 declared nutrients (combined weight 70); undeclared nutrients do not affect the score. Moisture was not declared and was estimated at 9.5% from the food type.

Low confidence: partial analysis or moisture estimated from the food type.

This measures agreement with published reference ranges, not suitability for an individual dog. For medical conditions, follow veterinary guidance.

Transparency: what the label discloses

How much the manufacturer discloses, measured against the FEDIAF Code of Good Labelling Practice and Regulation 767/2009. Mandatory items dominate the weighting.
