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 k/d + Mobility Dog Food
Dry Extruded complete veterinary diet
Is Hill's k/d + Mobility Dog Food a good dog food?
We score it 35/100 (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 for this recipe is 35 out of 100. Ingredients without printed percentages weighed the score down by -12.7 points, while the processing format reduced it by -7 points and the carbohydrate content took off a further -3.4 points. On the positive side, the meat content contributed +2.4 points. 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.
97% 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, venison, pork, duck as ingredients
Consider something else if:
- Your dog avoids fish: the label lists crustaceans
- Your dog avoids grain: the label lists cereals
- You are limiting fat: 22.7% on a dry-matter basis is in the high band
- You need more protein than this: 15.2% 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. Use the homepage filter to find foods that fit your dog.

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.
| Model | Score | |
|---|---|---|
| v2 | 35/100 | current |
| v1 | 32/100 | |
| v1.9 | 34/100 |
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 | 14 | 15.2 (band 18 to 40%) | 59.2 |
| Fat | 20.9 | 22.7 (band 5.5 to 20%) | 100 |
| Fibre | 2.1 | 2.3 (band 0.5 to 5%) | 93.8 |
| Calcium | 0.62 | 0.7 (band 0.5 to 2.5%) | 75.2 |
| Phosphorus | 0.28 | 0.3 (band 0.4 to 1.6%) | 53.3 |
| Calcium:phosphorus ratio | 2.2 | 2.2 (band 1 to 2%) | 89.3 |
| Energy (kcal/100g) | 402 | 437 | 50 |
Scored over 7 declared nutrients (combined weight 90); undeclared nutrients do not affect the score.
Portion-control flag: 402 kcal/100g as fed with fat at 22.7% dry matter, above the reference band. High-energy foods need smaller portions.
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 (3% of the recipe mass) (voluntary) | 0.6/20 |
| 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 |
| Batch and date labelling (mandatory) - not on file | 0/5 |
Capped at 60: mandatory items missing (Batch and date labelling).

Evidence: what the brand claims, and what supports it
The marketing claims made on the pack and product page, and how much evidence sits behind them. We record the claims as stated; we do not assess whether they are true.

| Formulated to improve ability to run, walk and jump in as little as 21 days (on page) | Functional | Manufacturer assertion |
| Supports natural ability to build and maintain muscle mass (on page) | Functional | Manufacturer assertion |
