Our verdict

Is Purina CA Adult Large Breed Shredded Blend Chicken & Rice Formula Dry Dog Food a good dog food?

We score it 40/100 (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".

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

  • 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 7% of the dry matter (11% 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 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: the label lists beef fat
  • 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. Find foods that fit your dog.

Recipe: how the 1-100 score is calculated

Why this score?

This recipe achieves a final score of 40 out of 100 based on several key factors. The overall quality of the ingredient list added +4 points. However, ingredients without printed percentages reduced the score by -10.6. Additionally, the processing format deducted -6.7 and the carbohydrate content contributed -2.3.

Scored with model v3 on 2026-10-25. Each component is the feature value for this product multiplied by the model's published coefficient.

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.

Omega fatty acids (omega-6 and omega-3)--100
Energy (kcal/100g)369407.7100

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 8 declared nutrients (combined weight 100); undeclared nutrients do not affect the score. Moisture was not declared and was estimated at 9.5% from the food type.

Declared fortification: 9 nutritional additives on the label
  • Vitamin A 15,000 IU/kg
  • Vitamin E 460 IU/kg
  • Vitamin C 70 mg/kg
  • Selenium 0.35 mg/kg
  • Linoleic Acid 1.7%
  • EPA 0.14%
  • DHA 0.12%
  • Glucosamine 500 ppm
  • Bacillus coagulans 600 million CFU/lb

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.

50/100 · limited — 2 checkable claims: 1 consistent, 1 contradicted.

Contradicted by the label

  • "High protein formula" — the declared label says otherwise on high protein.

Consistent with the label

  • "100% complete and balanced nutrition" — supported by the declared complete and balanced data.

7 further claims on file that we cannot check against the label.

Limited: at least one claim contradicts the declared label, or a recent upheld ASA ruling applies.
