Our verdict

Is ProDog Raw Flexx Joint Supplement 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.

Complementary supplement for dogs of all life stages, with msm, glucosamine and hemp protein as the main ingredients.

Final score

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.

Safety: recall history

Recall and safety-notice history, time-decayed. This dimension is shown alongside the score and never feeds the headline number.

No recalls recorded in our database.

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.
