How we score

The vet rating is the reviewing veterinarian’s approved overall judgment, weighing evidence, dosing, safety and value. It is not a formula.

We consider the research supporting a product’s claims, how its labelled dosing compares with the evidence, safety and tolerability, and value per labelled serving.

We cover the whole category and let a competitor win where it genuinely earns it.
