Is Aviform Flexus 10 Premium Hip and Joint Supplement for Dogs a good dog food?
This is a supplement, not a complete diet, so it is not scored on our 1-100 scale. The ingredient breakdown below shows what is in it; a supplement should be fed alongside, not instead of, a complete diet.
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.

Contributions are rounded to two decimals, so they may not sum exactly to the subtotal. The full coefficient table is published on the methodology page.
This is not a complete diet, so the 1-100 rating does not apply to it. Read the recipe breakdown above as ingredient-quality context only.
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.
| Model | Score | |
|---|---|---|
| v2 | 63/100 | current |
| v1 | 62/100 |
