Puppy Calorie Calculator
Calculate your puppy's daily calorie needs using age-adjusted growth factors — not adult dog formulas.
What Is the Puppy Calorie Calculator?
Calculate your puppy's daily calorie needs using age-adjusted growth factors — not adult dog formulas.
Adult calorie calculators seriously underestimate what puppies need. A 10-week-old puppy needs up to 2.5 times their resting energy requirement just to fuel normal growth. This calculator uses the correct age-adjusted growth factors so your puppy gets the energy they actually need.
Every result is based on published veterinary research and breed-size-specific growth data — not generic averages. This tool is completely free, works instantly in your browser, and requires no account or sign-up.

How It Works
Puppy calorie calculations start with the same RER formula as adults — 70 x (weight kg) to the power of 0.75. But instead of multiplying by an activity factor, we multiply by a growth factor that changes dramatically with age.
Under 8 weeks: 3.0x RER. Weeks 8-12: 2.5x RER. Weeks 12-20: 2.0x RER. Over 36 weeks: 1.6x RER. These high multipliers reflect the enormous energy cost of building bone, muscle, and organ tissue from scratch. Giant breeds get additional calories in early months because their growth sprint is more prolonged. As the growth factor approaches 1.0 at around 12 months, the puppy transitions to adult feeding calculations.
Veterinary Research
Every formula is derived from peer-reviewed veterinary studies and clinical guidelines, not guesswork or generic rules.
