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.
Hill's Pet Nutrition Prescription Diet t/d Small Bites Chicken Flavor Dry Dog Food
Dry Extruded complete veterinary diet
Is Hill's Pet Nutrition Prescription Diet t/d Small Bites Chicken Flavor Dry Dog Food a good dog food?
We score it 44/100 (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?
The overall score is 44 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 -2.3. 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.
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.
Why you might choose it
- Single named animal protein: chicken.
- Declares energy content, which most labels omit.
- Nutritionally complete: formulated to be fed as the whole diet.
Why you might not
- Only protein, fat and fibre declared; ash and moisture missing from the analysis.
- 100% of the recipe mass has no printed percentage, so the exact split cannot be verified.

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 |
| 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 7 declared nutrients (combined weight 90); undeclared nutrients do not affect the score. Moisture was not declared and was estimated at 9.5% from the food type.
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 |
Capped at 60: mandatory items missing (Analytical constituents declared, Batch and date labelling).
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.
100/100 · moderate — 1 checkable claim: 1 consistent, 0 contradicted.
Consistent with the label
- "Complete and balanced nutrition for maintenance of adult dogs" — supported by the declared complete and balanced data.
6 further claims on file that we cannot check against the label.
Moderate: every checkable claim is consistent with the declared label.
