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 l/d Dry Dog Food Original a good dog food?
We score it 20/100 (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 cereals, oils and fats and vegetable protein extracts as the main ingredients.
Declared analysis sits below the FEDIAF minimum for protein.
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, fish, venison, pork, duck as ingredients
Consider something else if:
- Your dog avoids grain: the label lists cereals
- You are limiting fat: 23.8% on a dry-matter basis is in the high band
- You need more protein than this: 18.2% 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 recipe achieves an overall rating of 20 out of 100. Several factors influenced this score. The presence of ingredients without printed percentages contributed -10.6 to the calculation. Additionally, the processing format added -6.7 while the carbohydrate content resulted in -5.4. Furthermore, the overall quality of the ingredient list adjusted the total by -5. 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 | 16.7 | 18.2 (band 19.907608695652172 to 40%) | 63.8 |
| Fat | 21.9 | 23.8 (band 6.082880434782608 to 20%) | 100 |
| Fibre | 2.4 | 2.6 (band 0.5 to 5%) | 98.1 |
| Calcium | 0.78 | 0.8 (band 0.5529891304347826 to 2.5%) | 79.1 |
| Phosphorus | 0.55 | 0.6 (band 0.4423913043478261 to 1.6%) | 78.1 |
| Sodium | 0.17 | 0.2 (band 0.11059782608695652+%) | 100 |
| Calcium:phosphorus ratio | 1.4 | 1.4 (band 1 to 2%) | 95.1 |
| Omega fatty acids (omega-6 and omega-3) | - | - | 100 |
| Energy (kcal/100g) | 407 | 442.4 | 50 |
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.
Portion-control flag: 407 kcal/100g as fed with fat at 23.8% dry matter, above the reference band. High-energy foods need smaller portions.
Declared fortification: 10 nutritional additives on the label
- Vitamin A 27,814 IU/kg
- Vitamin D3 715 IU/kg
- Vitamin E 550 mg/kg
- Vitamin C 90 mg/kg
- Beta-carotene 1.5 mg/kg
- Iron 19.7 mg/kg
- Iodine 1.3 mg/kg
- Manganese 3.9 mg/kg
- Zinc 136 mg/kg
- Selenium 0.2 mg/kg
High confidence: full analysis plus minerals or omegas and declared energy.
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) | 15/15 |
| Additives declared (mandatory) | 10/10 |
| Energy value declared (voluntary) | 5/5 |
| Complete/complementary designation (mandatory) | 5/5 |
| Feeding guidance given (mandatory) | 10/10 |
| Manufacturer identity and address (mandatory) | 10/10 |
| Country of manufacture stated (voluntary) | 10/10 |
