Our verdict
Is Hill's Pet Nutrition Prescription Diet t/d Small Bites Chicken Flavor Dry Dog Food a good dog food?
We score it 43/100 (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".
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
- Single named protein: chicken
- Doesn't list beef, turkey, lamb, fish, venison, pork, duck as ingredients
Consider something else if:
- Your dog avoids grain: the label lists rice - white
- You need more protein than this: 18.3% 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?
This food scored 43 out of 100. Undeclared ingredient shares came in at -10.6 points, because some ingredients are listed without printed percentages, and the processing format contributed -6.7 points while the additive load contributed -3.1 points. The overall quality of the ingredient list added +2.9 points, partly offsetting those deductions. 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 | 18.3 | 20.2 (band 18 to 40%) | 76.1 |
| Fat | 16.5 | 18.2 (band 5.5 to 20%) | 100 |
| Fibre | 10.8 | 11.9 (band 0.5 to 5%) | 100 |
| Calcium | 0.63 | 0.7 (band 0.5 to 2.5%) | 75.9 |
| Phosphorus | 0.45 | 0.5 (band 0.4 to 1.6%) | 74.9 |
| Sodium | 0.25 | 0.3 (band 0.1+%) | 100 |
| Calcium:phosphorus ratio | 1.4 | 1.4 (band 1 to 2%) | 94 |
| Energy (kcal/100g) | 347 | 383.4 | 100 |
Fibre: Declared as a maximum; the high-fibre taper is not applied.
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.
Declared fortification: 2 nutritional additives on the label
- Vitamin E 746 IU/kg
- Vitamin C 190 ppm
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 |
