How this score is used

Every ingredient's quality score feeds the ODF Score of every food that lists it, weighted by label position - the formula is public, down to the last penalty.

How our rating works

This is label analysis, not veterinary advice - if your dog has a health condition, talk to your vet before switching foods.
