Is Diamond Pet Foods Extreme Athlete Adult Dog Chicken & Rice Formula a good dog food?

We score it 50/100 (Average). This reflects the ingredient quality, composition and label transparency of the recipe as declared on the label.

How we score

Why this score?

This recipe achieves an overall rating of 50 out of 100. The inclusion of ingredients without printed percentages contributed -10.6 points, and the processing format adjusted the score by -6.7. Conversely, the overall quality of the ingredient list added +6.4 points, while being labelled nutritionally complete contributed +2.3 points to the final evaluation.

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.

Not recorded

The Recipe score measures how attractive and transparent the declared ingredient list is. It is not, by itself, proof that the food is nutritionally appropriate for long-term feeding. The Nutritional and Evidence scores measure what we can verify towards that stronger claim.

Why you might choose it

Single named animal protein: chicken.
Declares energy content, which most labels omit.
Nutritionally complete: formulated to be fed as the whole diet.

Why you might not

Meat makes up an estimated 5% of the dry matter (7% as fed); carbohydrates dominate.
100% of the recipe mass has no printed percentage, so the exact split cannot be verified.

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.

Nutrient	As fed (label)	Dry matter (scored)	Score
Protein	32	35.4 (band 18 to 40%)	100
Fat	25	27.6 (band 5.5 to 20%)	100
Fibre	4	4.4 (band 0.5 to 5%)	100
Omega fatty acids (omega-6 and omega-3)	-	-	100
Energy (kcal/100g)	411	454.1	50

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.

Portion-control flag: 411 kcal/100g as fed with fat at 27.6% dry matter, above the reference band. High-energy foods need smaller portions.

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.

Safety: recall history

Recall and safety-notice history, time-decayed. This dimension is shown alongside the score and never feeds the headline number.

No recalls recorded in our database.

Evidence: what the brand claims, and what supports it

The claims made on the pack and product page, checked against the declared label. We record claims as stated; "consistent" means our stored label data supports the claim, "contradicted" means it conflicts with it. Functional claims are recorded but never scored.
