Our verdict
Is Pro Plan NF Renal Function Dry Dog Food a good dog food?
We score it 38/100 (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".
Complete extruded dry food for adult dogs, with maize, rice and dried egg as the main ingredients.
Declared analysis sits below the FEDIAF minimum for protein.
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.
Who is this food for?
Suits
- Labelled by the manufacturer for adult dogs
- Doesn't list chicken, beef, turkey, lamb, venison, duck as ingredients
Consider something else if:
- Your dog avoids fish: the label lists fish oil
- Your dog avoids pork: the label lists pork fat
- Your dog avoids grain: the label lists maize / corn
- You want a single-protein recipe: this one lists more than one animal protein
- You need more protein than this: 13.0% on a dry-matter basis is in the low band
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.

Feeding and storage
Feeding guide
The recommended period of use is initially up to 6 months but lifetime use in case of irreversible disturbance of uric acid metabolism for reduction of urate stones formation. It is recommended that a veterinarian’s opinion be sought before use or before extending the period of use. Water should be available at all times. For dogs over 70kg: for each additional 5kg of body weight, feed an additional 25g of dry pet food. When feeding dry and wet, for each addition of 100g Canine NF wet can, reduce by 35g dry kibble. Substitute 100g of your dog’s current food with this sample. Body weight (kg) Dry (g/day) Dry + can combined Dry (g/day) Can/day: 2.5kg 65g, 20g, 1/3 can; 5kg 105g, 35g, 1/2 can; 10kg 165g, 30g, 1 can; 15kg 220g, 80g, 1 can; 25kg 310g, 170g, 1 can; 35kg 385g, 250g, 1 can; 45kg 455g, 320g, 1 can; 70kg 615g, 340g, 2 cans.

Recipe: how the 1-100 score is calculated
Why this score?
The overall score is 38 out of 100. Ingredients without printed percentages contributed -10.6, and the processing format contributed -6.7. The overall quality of the ingredient list contributed +3.2, while the carbohydrate content contributed -2.8. This is a general explanation of how the score works, not veterinary advice. For any health condition, food choice is a decision for your vet.
Scored with model v3 on 2026-10-25. Each component is the feature value for this product multiplied by the model's published coefficient.

Score history across model versions
The score shown above is always computed with the latest published model. Earlier scores are kept for the record and are never edited or deleted; a scoring change ships as a new model version with a public write-up 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.
| Nutrient | As fed (label) | Dry matter (scored) | Score |
|---|---|---|---|
| Protein | 13 | 14.4 (band 19.39226519337017 to 40%) | 51.9 |
| Fat | 14.5 | 16 (band 5.9254143646408854 to 20%) | 100 |
| Fibre | 2 | 2.2 (band 0.5 to 5%) | 92.8 |
| Calcium | 0.8 | 0.9 (band 0.5386740331491714 to 2.5%) | 80.6 |
| Phosphorus | 0.4 | 0.4 (band 0.43093922651933714 to 1.6%) | 70.6 |
| Sodium | 0.2 | 0.2 (band 0.10773480662983428+%) | 100 |
| Calcium:phosphorus ratio | 2 | 2 (band 1 to 2%) | 100 |
| Omega fatty acids (omega-6 and omega-3) | - | - | 100 |
| Energy (kcal/100g) | 390 | 430.9 | 100 |
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 9 declared nutrients (combined weight 105); 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
- Vit A: 31,000 IU/kg
- Vit D3: 1,000 IU/kg
- Vit E: 350 IU/kg
- Iron (II) sulphate monohydrate: (Fe: 200 mg/kg)
- Calcium iodate anhydrous: (I: 3.1 mg/kg)
- Copper (II) sulphate pentahydrate: (Cu: 21 mg/kg)
- Manganous sulphate monohydrate: (Mn: 74 mg/kg)
- Zinc sulphate monohydrate: (Zn: 185 mg/kg)
- Sodium selenite: (Se: 0.22 mg/kg)
Medium confidence: the full five-part analysis is on file; where moisture was not declared it was 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.

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.
