Virbac Kidney Support Dog Food K1
Dry Extruded complete

Is Virbac Kidney Support Dog Food K1 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.
Why this score?
This recipe achieves an overall score of 50 out of 100 based on several key factors. On the positive side, the overall quality of the ingredient list adds +5.2 points, and printing percentages for most of the recipe contributes +2 points. However, the score is reduced by -13.1 points due to ingredients without printed percentages, and the processing format subtracts -7 points.
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.
Complete extruded dry food for dogs of all life stages, with rice, poultry and unspecified animal fats and oils as the main ingredients.
Why you might choose it
- Nutritionally complete: formulated to be fed as the whole diet.
Why you might not
- High in fat: 24% fat on a dry-matter basis.
- 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 all lifestages
- Doesn't list beef, lamb, venison, duck as ingredients
Consider something else if:
- Your dog avoids chicken: the label lists poultry
- Your dog avoids turkey: the label lists poultry
- Your dog avoids fish: the label lists fish oil
- Your dog avoids pork: the label lists hydrolysed pork
- Your dog avoids grain: the label lists rice - white
- You want a single-protein recipe: this one lists more than one animal protein
- You are limiting fat: 24.2% 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. Use the homepage filter to 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.

|---|---|---|
| v2 | 50/100 | current |
| v1 | 50/100 | |
| v1.9 | 50/100 |
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 | 20.5 | 22.5 (band 18 to 40%) | 82.3 |
| Fat | 22 | 24.2 (band 5.5 to 20%) | 100 |
| Fibre | 5.5 | 6 (band 0.5 to 5%) | 100 |
| Calcium | 0.8 | 0.9 (band 0.5 to 2.5%) | 81.4 |
| Phosphorus | 0.4 | 0.4 (band 0.4 to 1.6%) | 72 |
| Calcium:phosphorus ratio | 2 | 2 (band 1 to 2%) | 100 |
| 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.
Medium confidence: the full five-part analysis is on file; where moisture was not declared it was 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) - 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 (Feeding guidance given, Batch and date labelling).
