Our verdict
Is Lifelong Duck + Sweet Potato Recipe a good dog food?
We score it 60/100 (Average). This reflects the ingredient quality, composition and label transparency of the recipe as declared on the label.
Complete wet food in chunks for dogs of all life stages, with duck, turkey and cooking broth as the main ingredients.
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 all lifestages
- Grain-free: no grain ingredients listed
- Doesn't list beef, lamb, fish, venison, pork as ingredients
Consider something else if:
- Your dog avoids chicken: the label lists chicken liver
- Your dog avoids turkey: the label lists turkey
- Your dog avoids duck: the label lists duck
- You want a single-protein recipe: this one lists more than one animal protein
- You are limiting fat: 27.3% 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.

Score history across model versions
The score shown above is always computed with the latest published model. Earlier scores are kept for the record and are never edited or deleted; a scoring change ships as a new model version with a public write-up on the methodology page.
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.
| Nutrient | As fed (label) | Dry matter (scored) | Score |
|---|---|---|---|
| Protein | 8 | 36.4 (band 20.045454545454547 to 40%) | 100 |
| Fat | 6 | 27.3 (band 6.125000000000001 to 20%) | 100 |
| Fibre | 1.5 | 6.8 (band 0.5 to 5%) | 100 |
| Energy (kcal/100g) | 98 | 445.5 | 100 |

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.
