Dog Food Calculator
How this calculator works
This calculator starts with your dog's resting energy requirement (RER), a standard veterinary formula based on body weight, and multiplies it by a factor for life stage and activity level. The result is a daily calorie target, converted into cups using a typical dry-food energy density of about 350 kcal per cup.
Frequently Asked Questions
How many times a day should I feed my dog?
Most adult dogs do well with two meals a day. Puppies usually need three to four smaller meals until about six months of age.
Why does the result differ from my food bag's chart?
Feeding charts are generic starting points. This calculator adjusts for your individual dog's weight, life stage and activity, and calorie density varies between brands — always check the label.
Should the cups be split between meals?
Yes. The total is for the whole day, so divide it across however many meals you feed.
