Our verdict
Is K9 Optimum Senior Chicken a good dog food?
We score it 63/100 (Average). This reflects the ingredient quality, composition and label transparency of the recipe as declared on the label.
Complete extruded dry food for senior dogs, with chicken, dried poultry and rice as the main ingredients.
Only part of the analytical constituents are declared, so the nutritional picture is incomplete.
50% 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 senior dogs
- Doesn't list beef, lamb, venison, pork, duck as ingredients
Consider something else if:
- Your dog avoids chicken: the label lists chicken
- Your dog avoids turkey: the label lists dried poultry
- Your dog avoids fish: the label lists salmon
- Your dog avoids grain: the label lists rice - white
- 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?
This recipe achieves an overall score of 63 out of 100 based on several key factors. The meat content contributed +3.2 points, while the overall quality of the ingredient list added +6.2 points. However, the processing format reduced the score by -6.7 points, and ingredients without printed percentages resulted in a deduction of -5.3 points.
Scored with model v3 on 2026-10-25. Each component is the feature value for this product multiplied by the model's published coefficient.

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 | 25 | 27.6 (band 18 to 40%) | 96.2 |
| Fat | 12 | 13.3 (band 5.5 to 20%) | 100 |
| Fibre | 4.5 | 5 (band 0.5 to 5%) | 100 |
| Calcium | 1.3 | 1.4 (band 0.5 to 2.5%) | 98.1 |
| Phosphorus | 1 | 1.1 (band 0.4 to 1.6%) | 100 |
| Calcium:phosphorus ratio | 1.3 | 1.3 (band 1 to 2%) | 88 |
| Omega fatty acids (omega-6 and omega-3) | - | - | 100 |
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 9.5% from the food type.
Declared fortification: 8 nutritional additives on the label
- 3a672a Vitamin A 18000 IU
- 3a671 Vitamin D3 1200 IU
- 3a700 Vitamin E 150 IU
- 3b605 & 3b606 Zinc 153 mg
- 3b103 & 3b106 Iron 95 mg
- 3b503 Manganese 35 mg
- 3b405 & 3b406 Copper 6 mg
- 3b202 Iodine 1 mg
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 (50.1% of the recipe mass) (voluntary) | 10/20 |
| Analytical constituents declared (mandatory) - not on file | 0/15 |
| Additives declared (mandatory) | 5/10 |
| Energy value declared (voluntary) - not on file | 0/5 |
| Complete/complementary designation (mandatory) | 5/5 |
| Feeding guidance given (mandatory) - not on file | 0/10 |
| Manufacturer identity and address (mandatory) | 5/10 |
| Country of manufacture stated (voluntary) | 10/10 |
| Batch and date labelling (mandatory) - not on file | 0/5 |
Capped at 60: mandatory items missing (Analytical constituents declared, Feeding guidance given, Batch and date labelling).
