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 rating

Is Hill's Pet Nutrition d/d Potato & Duck Recipe Dog Food a good dog food?

We score it 40/100 (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 score is 40 out of 100. Ingredients without printed percentages contributed -10.6 points, the processing format contributed -6.7 points, the overall quality of the ingredient list contributed +3.7 points, and the oil and fat content contributed -2.8 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.

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

Why you might not

  • Meat makes up an estimated 6% of the dry matter (14% as fed); carbohydrates dominate.
  • No analytical breakdown is published.
  • 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 as ingredients

Consider something else if:

  • Your dog avoids fish: the label lists fish oil
  • Your dog avoids pork: it is listed as an ingredient
  • 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

Analytical constituents not declared

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.

0/100 · limited — 1 checkable claim: 0 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.

11 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.
