Dry Extruded complete
Is Pro Plan NF Renal Function Dry Dog Food a good dog food?
We score it 37/100 (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 score of 37 out of 100. Ingredients without printed percentages adjust the rating by -13.1. Furthermore, the processing format contributes -7 to the overall score. The carbohydrate content also adjusts the total by -2.8. Finally, the additive load influences the result by -2.7.
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.

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.
Complete extruded dry food for adult dogs, with maize, rice and dried egg as the main ingredients.
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
- 3 poor-graded ingredients make up about 29% of the recipe.
- Low in protein: 13% protein on a dry-matter basis.
- 100% of the recipe mass has no printed percentage, so the exact split cannot be verified.

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.

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. 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.
| Nutrient | As fed (label) | Dry matter (scored) | Score |
|---|---|---|---|
| Protein | 13 | 14.1 (band 18 to 40%) | 55 |
| Fat | 14.5 | 15.8 (band 5.5 to 20%) | 100 |
| Fibre | 2 | 2.2 (band 0.5 to 5%) | 92.3 |
| Calcium | 0.8 | 0.9 (band 0.5 to 2.5%) | 81.1 |
| Phosphorus | 0.4 | 0.4 (band 0.4 to 1.6%) | 71.7 |
| Calcium:phosphorus ratio | 2 | 2 (band 1 to 2%) | 100 |
| Omega fatty acids (omega-6 and omega-3) | - | - | 100 |
| Energy (kcal/100g) | 390 | 423.9 | 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 8 declared nutrients (combined weight 100); undeclared nutrients do not affect the score. Moisture was not declared and was estimated at 8% from the food type.
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.
| 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) | 5/10 |
| Energy value declared (voluntary) | 5/5 |
| Complete/complementary designation (mandatory) | 5/5 |
| Feeding guidance given (mandatory) | 10/10 |
| Manufacturer identity and address (mandatory) | 5/10 |
| 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).
