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 rating

Is Hill's Prescription Diet k/d + Mobility Dog Food a good dog food?

We score it 38/100 (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".

How we score

Why this score?

The overall score reaches 38 out of 100. Undeclared ingredient shares, meaning ingredients without printed percentages, contributed -10.3. The remaining ingredients contributed -3.5, lower-quality ingredients added -3.2, and the additive load contributed -2.6. 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.

98% 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.

Complete extruded dry food for adult dogs, with meat and animal derivatives, chicken and vegetable by as the main ingredients.

Why you might choose it

  • Declares energy content, which most labels omit.
  • Nutritionally complete: formulated to be fed as the whole diet.

Why you might not

  • 5 poor-graded ingredients make up about 49% of the recipe.
  • High in fat: 22% fat on a dry-matter basis.

Who is this food for?

Suits

  • Labelled by the manufacturer for adult dogs
  • Doesn't list beef, turkey, lamb, venison, duck as ingredients

Consider something else if:

  • Your dog avoids chicken: the label lists chicken
  • Your dog avoids fish: the label lists crustaceans
  • Your dog avoids pork: the label lists pork liver
  • Your dog avoids grain: the label lists oat bran
  • You want a single-protein recipe: this one lists more than one animal protein
  • You are limiting fat: 22.3% on a dry-matter basis is in the high band
  • You need more protein than this: 16.5% 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.

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.

Energy (kcal/100g)112430.8100

Scored over 7 declared nutrients (combined weight 90); undeclared nutrients do not affect the score.

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.

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

  • "Low level of phosphorus, restricted level of high-quality protein, high levels of EPA and total omega-3 fatty acids, and adequate level of vitamin E" — supported by the declared low protein data.

8 further claims on file that we cannot check against the label.

Moderate: every checkable claim is consistent with the declared label.
