Work out how much to feed your dog by combining the daily calories your dog needs with the calorie density printed on the food bag. Most dog foods list a kcal per cup or kcal per kilogram value, and dividing your dog daily energy requirement by that density gives the portion to serve. This tool takes your dog daily calories and the food energy per cup, then returns cups per day and, if you split meals, the amount per serving. It also shows an approximate weight in grams using a typical kibble density so you can weigh portions for accuracy. Feeding by weight is more precise than by scoop, which helps prevent gradual weight gain. Everything runs in your browser. This is general guidance, not veterinary advice, so adjust to your dog body condition and follow the food label and your vet.
It divides your dog daily calorie need by the food energy density in calories per cup, giving the number of cups per day. It also converts that into grams if you enter the food weight per cup.
The value, often labelled kcal per cup or metabolizable energy, is printed on the food bag or the manufacturer website. Enter it exactly for an accurate portion.
Yes, most adult dogs do best on two meals, so divide the daily cups in half. The tool shows the full day amount, so split it across your feeding schedule.
