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 Pet Nutrition z/d Hydrolyzed Chicken Flavor Dog Food a good dog food?
We score it 50/100 (Average). This reflects the ingredient quality, composition and label transparency of the recipe as declared on the label.
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.
Who is this food for?
Suits
- Labelled by the manufacturer for adult dogs
- Doesn't list beef, turkey, lamb, venison, pork, duck as ingredients
Consider something else if:
- Your dog avoids chicken: the label lists hydrolysed chicken liver
- Your dog avoids fish: the label lists fish oil
- Your dog avoids grain: it is listed as an ingredient
- 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. Find foods that fit your dog.

Recipe: how the 1-100 score is calculated
Why this score?
We rate this product at 50 out of 100. Undeclared ingredient shares, meaning ingredients without printed percentages, contributed -10.6 points. The overall quality of the ingredient list contributed +3.2 points, and being labelled nutritionally complete contributed +2.3 points. The oil and fat content had a negative effect of -1.9 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.
Scored with model v3 on 2026-10-25. Each component is the feature value for this product multiplied by the model's published coefficient.

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.
| Nutrient | As fed (label) | Dry matter (scored) | Score |
|---|---|---|---|
| Protein | 21.2 | 96.4 (band 19.738636363636367 to 40%) | 100 |
| Fat | 16 | 72.7 (band 6.03125 to 20%) | 100 |
| Fibre | 4.8 | 21.8 (band 0.5 to 5%) | 100 |
| Calcium | 0.83 | 3.8 (band 0.5482954545454546 to 2.5%) | 49.1 |
| Phosphorus | 0.59 | 2.7 (band 0.4386363636363637 to 1.6%) | 32.4 |
| Sodium | 0.31 | 1.4 (band 0.10965909090909093+%) | 100 |
| Calcium:phosphorus ratio | 1.4 | 1.4 (band 1 to 2%) | 94.4 |
| Omega fatty acids (omega-6 and omega-3) | - | - | 100 |
| Energy (kcal/100g) | 96.5 | 438.6 | 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 9 declared nutrients (combined weight 105); undeclared nutrients do not affect the score. Moisture was not declared and was estimated at 78% from the food type.
Declared fortification: 16 nutritional additives on the label
- Vitamin E Supplement
- L-Ascorbyl-2-Polyphosphate (source of Vitamin C)
- Thiamine Mononitrate
- Niacin Supplement
- Calcium Pantothenate
- Vitamin B12 Supplement
- Pyridoxine Hydrochloride
- Biotin
- Vitamin D3 Supplement
- Riboflavin Supplement
- Folic Acid
- Ferrous Sulfate
- Zinc Oxide
- Copper Sulfate
- Manganese Sulfate
- Calcium Iodate
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.
| 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) - not on file | 0/15 |
| Additives declared (mandatory) | 5/10 |
| Energy value declared (voluntary) | 5/5 |
| Complete/complementary designation (mandatory) | 5/5 |
| Feeding guidance given (mandatory) | 10/10 |
| Manufacturer identity and address (mandatory) | 5/10 |

Evidence: what the brand claims, and what supports it
