How much should I feed my dog?
Estimate daily calories, cups per day, and monthly cost for any dry food. Enter your pet’s details — add a food’s calories-per-cup and price-per-kg to see portions and cost.
Estimates only — not veterinary advice. These figures use standard veterinary energy formulas and assume a healthy, typical pet. Growing, pregnant, nursing, or unwell animals and those on prescription diets differ. Always confirm portions with your veterinarian and the feeding guide printed on the bag.

Frequently asked questions
How much dry food should I feed my dog or cat?
Start from your pet's daily calorie needs, then divide by the calories per cup printed on your food's bag. This calculator estimates daily calories from resting energy (70 × weight in kg ^ 0.75) multiplied by a lifestyle factor, then converts that to cups once you enter the food's kcal/cup. Always cross-check against the feeding guide on the bag and adjust to keep your pet at a healthy body condition.
Why do neutered pets need fewer calories?
Spaying or neutering lowers metabolic rate, so neutered adults use a lower maintenance factor (about 1.6× resting energy for dogs, 1.2× for cats) than intact ones. Feeding them like an intact or active animal is a common cause of slow weight gain.
Should I measure food in cups or grams?
Grams are far more accurate — a "cup" varies with kibble size and how you scoop. We show both: the calculator assumes about 110 g per cup by default (editable under Advanced) so you can weigh portions on a kitchen scale for consistency.
How is the monthly cost estimated?
We take the grams per day from the plan, multiply by your food's price per kilogram, and scale to an average month (30.4 days). It is an estimate for comparing foods, not an exact bill.
Is this a substitute for veterinary advice?
No. These are general estimates based on standard veterinary energy formulas. Growing, pregnant, nursing, or unwell pets and those on prescription diets have different needs — confirm any feeding plan with your veterinarian.
