Is Purina US Adult Large Breed Chicken & Rice Formula Dry Dog Food a good dog food?
We score it 44/100 (Poor). The main reasons are set out in "Why you might not" below, and every step of the calculation is shown under "How we calculated this score".
Why this score?
This recipe achieves an overall rating of 44 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 +4.8 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.

- Transparency60
- Safety100
- EvidenceNot 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
- 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 8% of the dry matter (11% as fed); carbohydrates dominate.
- Only protein and fat declared; fibre, ash and moisture missing from the analysis.
- 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 adult dogs
- Labelling or feeding guide is aimed at large dogs
- Doesn't list lamb, venison, pork, duck as ingredients
Consider something else if:
- Your dog avoids chicken: the label lists chicken
- Your dog avoids beef: it is listed as an ingredient
- Your dog avoids turkey: the label lists poultry
- Your dog avoids fish: the label lists fish meal
- Your dog avoids grain: the label lists rice - white
- You want a single-protein recipe: this one lists more than one animal protein
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. Use the homepage filter to find foods that fit your dog.

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 | 26 | 28.7 (band 18 to 40%) | 99.3 |
| Fat | 12 | 13.3 (band 5.5 to 20%) | 100 |
| Energy (kcal/100g) | 382 | 422.1 | 100 |
Scored over 3 declared nutrients (combined weight 50); 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.
| Item | Points |
|---|---|
| Ingredient list on the label (mandatory) | 10/10 |
| Printed percentages on the label (voluntary) - not on file | 0/20 |
| Analytical constituents declared (mandatory) - not on file | 0/15 |
| Additives declared (mandatory) | 10/10 |
| Energy value declared (voluntary) | 5/5 |
| Complete/complementary designation (mandatory) | 5/5 |
| Feeding guidance given (mandatory) | 10/10 |
| Manufacturer identity and address (mandatory) | 10/10 |
| Country of manufacture stated (voluntary) | 10/10 |
| Batch and date labelling (mandatory) - not on file | 0/5 |
Capped at 60: mandatory items missing (Analytical constituents declared, Batch and date labelling).
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.
Claims on file; none we can check against the label
| Claim | Type | Check | Substantiation |
|---|---|---|---|
| Glucosamine and EPA, an omega-3 fatty acid, for joint health and mobility (on page) | Functional | not checkable | Manufacturer assertion |
| Highly digestible formula for optimal nutrient delivery (on page) | Functional | not checkable | Manufacturer assertion |
| Omega-6 fatty acids and vitamin A to nourish skin and coat (on page) | Functional | not checkable | Manufacturer assertion |
| No artificial colors or flavors (on page) | Free-from | not checkable | Manufacturer assertion |
