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.

Is Hill's Pet Nutrition d/d Duck Formula Wet Dog Food a good dog food?

We score it 48/100 (Average). This reflects the ingredient quality, composition and label transparency of the recipe as declared on the label.

How we score

Why this score?

The recipe reached a score of 48 out of 100. The overall quality of the ingredient list contributed +4.2 points, while undeclared ingredient shares cost -10.6 points. The oil and fat content cost -2.4 points, and the additive load reduced the score by -1.7 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.

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

  • Doesn't list grain ingredients.
  • Nutritionally complete: formulated to be fed as the whole diet.

Why you might not

  • Meat makes up an estimated 9% of the dry matter (18% as fed); carbohydrates dominate.
  • 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.

Who is this food for?

Suits

  • Labelled by the manufacturer for adult dogs
  • Grain-free: no grain ingredients listed
  • Doesn't list chicken, beef, turkey, lamb, venison, pork as ingredients

Consider something else if:

  • Your dog avoids fish: the label lists fish oil
  • Your dog avoids duck: the label lists duck
  • You want a single-protein recipe: this one lists more than one animal protein

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.

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.

NutrientAs fed (label)Dry matter (scored)Score
Protein17.278.2 (band 18 to 40%)100
Fat16.474.5 (band 5.5 to 20%)100
Fibre313.6 (band 0.5 to 5%)100
Calcium0.924.2 (band 0.5 to 2.5%)32.7
Phosphorus0.622.8 (band 0.4 to 1.6%)23.9
Calcium:phosphorus ratio1.51.5 (band 1 to 2%)99
Omega fatty acids (omega-6 and omega-3)--100

Fibre: Declared as a maximum; the high-fibre taper is not applied.

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 7 declared nutrients (combined weight 90); undeclared nutrients do not affect the score. Moisture was not declared and was estimated at 78% 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.

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.

50/100 · limited — 2 checkable claims: 1 consistent, 1 contradicted.

Contradicted by the label

  • "Limited ingredient nutrition with a single, animal protein to avoid common allergens in dogs with food sensitivities" — the declared label says otherwise on single protein.

Consistent with the label

  • "Animal feeding tests using AAFCO procedures substantiate that Hill's Prescription Diet d/d Duck Recipe Dog Food provides complete and balanced nutrition for maintenance of adult dogs" — supported by the declared complete and balanced data.

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

Limited: at least one claim contradicts the declared label, or a recent upheld ASA ruling applies.
