Our verdict
Is ZIWI Tripe & Lamb a good dog food?
We score it 69/100 (Average). This reflects the ingredient quality, composition and label transparency of the recipe as declared on the label.
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 all lifestages
- Grain-free: no grain ingredients listed
- Doesn't list chicken, beef, turkey, venison, pork, duck as ingredients
Consider something else if:
- Your dog avoids lamb: the label lists lamb tripe
- Your dog avoids fish: the label lists green-lipped mussel
- You want a single-protein recipe: this one lists more than one animal protein
- You are limiting fat: 27.9% on a dry-matter basis is in the high 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. 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.
| Nutrient | As fed (label) | Dry matter (scored) | Score |
|---|---|---|---|
| Protein | 44 | 49 (band 24.55456570155902 to 40%) | 100 |
| Fat | 24 | 26.7 (band 7.502783964365256 to 20%) | 100 |
| Fibre | 3 | 3.3 (band 0.5 to 5%) | 100 |
| Energy (kcal/100g) | 490 | 545.7 | 50 |
Scored over 4 declared nutrients (combined weight 60); undeclared nutrients do not affect the score. Moisture was not declared and was estimated at 10.2% from the food type.
Portion-control flag: 490 kcal/100g as fed with fat at 26.7% dry matter, above the reference band. High-energy foods need smaller portions.
Declared fortification: 13 nutritional additives on the label
- Dipotassium Phosphate
- Magnesium Sulfate
- Zinc Amino Acid Complex
- Iron Amino Acid Complex
- Copper Amino Acid Complex
- Manganese Amino Acid Complex
- Selenium Yeast
- Vitamin E Supplement
- Thiamine Mononitrate
- Riboflavin
- Pyridoxine Hydrochloride
- Vitamin D3 Supplement
- Folic Acid
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) | 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) | 5/10 |
| Country of manufacture stated (voluntary) | 10/10 |
| Batch and date labelling (mandatory) - not on file | 0/5 |
