Pocket VetDog calorie calculator
Estimate your dog's daily calorie needs from resting energy (RER) and an activity factor (MER), and how many cups to feed based on your diet's energy density.
Frequently asked
How many calories does my dog need per day?
Start from RER = 70 × (weight in kg)^0.75, then multiply by an activity factor (about 1.6 for a neutered adult). The result is a starting estimate — adjust to your dog's body condition.
How much should I feed my dog?
Divide the daily calorie target by your food's calories per cup. Split into two or more meals and re-check body condition every few weeks.
