About the Dog Calorie Calculator

Veterinary nutrition starts from the Resting Energy Requirement: RER = 70 × (body weight in kg)^0.75. The exponent means calories scale sub-linearly with weight — a 30 lb dog needs about 420 kcal at rest, not double a 15 lb dog's needs.

Adjusting for Life Stage

MER multiplies RER by activity and life-stage factors: neutered adults 1.6, intact 1.8, puppies and working dogs 2.0, weight-loss plans 1.0. These are starting points — monitor body condition monthly and adjust portion sizes by 10% as needed.
