Why BreedLookup
BreedLookup calculates daily calorie needs using the Resting Energy Requirement formula from the National Research Council's Nutrient Requirements of Dogs and Cats (2006), the same methodology used by veterinary nutritionists at Ohio State, Tufts, and UC Davis. Breed weight ranges come from AKC and TICA standards. Age conversion uses epigenetic research published in Cell Systems (2020) by UC San Diego researchers.
Every tool is free, requires no account, and works with any food brand. See our sources and methodology.
