Frequently asked
How much Blue Buffalo for a 25 kg dog?
At 378 kcal/100 g, a neutered 25 kg dog eats ~298 g/day (1,253 kcal target, treats removed), split ~149 g per meal.
Blue Buffalo vs the bag chart?
Blue's chart, like most, assumes a more active dog than the average pet. The formula number with your label kcal is the tiebreaker.
How many cups of Blue Buffalo is that per day?
About 2.5 cups at a typical 100 g cup — but cups vary by up to 40% between kibbles and scoops, which is why this page works in grams (252 g/day for a 20 kg neutered dog). Weigh once, and the cup question disappears.
Why does the Blue Buffalo bag chart suggest a different amount?
Bag charts are printed for the average dog of each size and tend to run generous. This calculator uses your dog's actual weight and life stage against Blue Buffalo's representative energy (378 kcal/100 g) — if your exact formula's label differs, enter its kcal/kg ÷ 10 and the portion rescales instantly.
