Frequently asked questions
- How many calories should my dog eat per day?
- Start from the resting energy requirement (RER = 70 × weight_kg^0.75) and multiply by a life-stage factor (e.g. ~1.6 for a neutered adult). This calculator does the math — confirm with your vet.
- How do I convert calories to cups?
- Enter the kcal per cup printed on your food bag and the calculator divides daily calories by that number to estimate cups per day.
