How it works
Three steps to a transparent pet food score
We score every ingredient individually per species, then compose a final A to E grade. No marketing claims, no brand influence.
- 01
Search the product
Find a brand by name, paste a composition, or scan a barcode. The database covers thousands of commercial pet foods.
- 02
PetFoodRate analyses
Every ingredient is scored individually per species using our curated database of 500+ ingredients with benefits, risks, and scientific notes.
- 03
Get an A to E grade
The final grade is composed from five sub-scores: proteins, nutrition balance, undesirables, transparency, and species adaptability.

FAQ
Questions we hear every day
How does PetFoodRate score pet food?
Every product is scored from A to E across five dimensions: proteins, nutrition balance, undesirables (artificial additives, preservatives, ambiguous fillers), transparency (named vs unnamed ingredients), and species adaptability. Each ingredient in our database carries its own score, and the product score is a weighted composition of its ingredients.
Which pets does PetFoodRate cover?
PetFoodRate covers ten species: dogs, cats, rabbits, hamsters, guinea pigs, chinchillas, ferrets, birds, turtles, and reptiles. Every ingredient is scored separately for each species because nutritional needs vary significantly (for example, taurine is essential for cats but neutral for dogs).
Is PetFoodRate really free?
Yes. Browsing product scores, comparisons, and the ingredient encyclopedia is free. PetFoodRate is funded through affiliate partnerships with major pet food retailers (Chewy, Zooplus, Amazon) and display advertising. We never accept payment to change a score.
How honest are the scores?
Our scoring algorithm, ingredient database, and methodology are fully documented on the Methodology page. Scores are deterministic: given the same ingredient composition, you always get the same A to E grade. Our commercial partners do not influence scoring.
