veterinary diet
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.

Dry Extruded · completeveterinary diet
Our verdict
Is Virbac Urology Dissolution & Prevention U1 a good dog food?
We score it 48/100 (Average). This reflects the ingredient quality, composition and label transparency of the recipe as declared on the label.
Complete extruded dry food for adult dogs, with poultry, rice and unspecified animal fats and oils as the main ingredients.
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, 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
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?
The overall score is 48 out of 100. Ingredients without printed percentages contributed -10.6 points, and the processing format contributed -6.7 points. The overall quality of the ingredient list contributed +4.9 points, with being labelled nutritionally complete adding +2.3. 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.

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 | 34 | 37.4 (band 18 to 40%) | 100 |
| Fat | 17.5 | 19.2 (band 5.5 to 20%) | 100 |
| Fibre | 5 | 5.5 (band 0.5 to 5%) | 100 |
| Calcium | 0.8 | 0.9 (band 0.5 to 2.5%) | 81.4 |
| Phosphorus | 0.6 | 0.7 (band 0.4 to 1.6%) | 83 |
| Sodium | 0.9 | 1 (band 0.1+%) | 100 |
| Calcium:phosphorus ratio | 1.3 | 1.3 (band 1 to 2%) | 90 |
| 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 8 declared nutrients (combined weight 95); undeclared nutrients do not affect the score.
Declared fortification: 17 nutritional additives on the label
- Vitamin A 11000 IU
- Vitamin D3 1100 IU
- Vitamin E 570 mg
- Vitamin B1 3.8 mg
- Vitamin B2 11 mg
- Vitamin B3 30 mg
- Vitamin B5 26 mg
- Vitamin B6 3 mg
- Vitamin B9 0.48 mg
- Vitamin B12 0.062 mg
- Choline 740 mg
- Taurine 1500 mg
- Copper 15 mg
- Iron 25 mg
- Iodine 1.1 mg
- Zinc 120 mg
- L-carnitine 330 mg
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).

Evidence: what the brand claims, and what supports it
The claims made on the pack and product page, checked against the declared label. We record claims as stated; "consistent" means our stored label data supports the claim, "contradicted" means it conflicts with it. Functional claims are recorded but never scored.
100/100 · strong — 3 checkable claims: 3 consistent, 0 contradicted.
Consistent with the label
- "High protein and sodium content encourages water intake to increase urination" — supported by the declared high protein data.
- "Contains a high-quality protein content (34%) to increase water intake, thereby increasing urine volume and frequency" — supported by the declared high protein data.
- "34% high-quality protein (85% animal origin) improves the palatability of the food and also stimulates water intake which increases urine volume and helps to keep the urine dilute" — supported by the declared high protein data.
21 further claims on file that we cannot check against the label.
Strong: at least three checkable claims, all consistent with the declared label, and no compliance cap.
