veterinary diet
This is a medical nutrition decision. Speak to your vet.
This is a veterinary diet product: a "dietetic" feed designed for a particular nutritional purpose and intended for use under veterinary direction. The score and figures below are readings of the label, the same as for any other food: they can't tell you whether this product is right for your dog.

Our verdict
Is Hill's Pet Nutrition Prescription Diet Derm Complete Rice & Egg Recipe Dry Dog Food a good dog food?
We score it 45/100 (Average). This reflects the ingredient quality, composition and label transparency of the recipe as declared on the label.
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 beef, turkey, lamb, venison, pork, duck as ingredients
Consider something else if:
- Your dog avoids chicken: the label lists chicken
- Your dog avoids fish: the label lists fish oil
- Your dog avoids grain: the label lists rice - brown / whole grain
- You want a single-protein recipe: this one lists more than one animal protein
- You need more protein than this: 17.3% 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.

Recipe: how the 1-100 score is calculated
Why this score?
The overall score is 45 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 +4.9, while the carbohydrate content contributed -2.7. 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.

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 | 17.3 | 19.1 (band 18.994475138121548 to 40%) | 70.3 |
| Fat | 17.4 | 19.2 (band 5.803867403314918 to 20%) | 100 |
| Fibre | 1.4 | 1.5 (band 0.5 to 5%) | 84 |
| Calcium | 0.62 | 0.7 (band 0.5276243093922652 to 2.5%) | 74.8 |
| Phosphorus | 0.54 | 0.6 (band 0.42209944751381223 to 1.6%) | 78.9 |
| Sodium | 0.22 | 0.2 (band 0.10552486187845306+%) | 100 |
| Calcium:phosphorus ratio | 1.1 | 1.1 (band 1 to 2%) | 78.9 |
| Energy (kcal/100g) | 382 | 422.1 | 100 |
Scored over 8 declared nutrients (combined weight 95); undeclared nutrients do not affect the score. Moisture was not declared and was estimated at 9.5% from the food type.
No nutritional additives section declared on the label.
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) | 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 |

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.
0/100 · limited — 1 checkable claim: 0 consistent, 1 contradicted.
Contradicted by the label
- "Single, high quality, intact animal protein to help avoid adverse reactions to food" — the declared label says otherwise on single protein.
8 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.
