How This Calculator Works

This calculator uses the veterinary-standard Resting Energy Requirement (RER) formula:

RER = 70 × (body weight in kg)0.75

The RER is then multiplied by a factor based on your dog's life stage, activity level, and neutering status to determine their Maintenance Energy Requirement (MER) — the total daily calories they need.

Activity Level Multipliers

FactorMultiplier
Neutered adult, low activity1.2 - 1.4
Intact adult, moderate activity1.6 - 1.8
Active/working dog2.0 - 5.0
Puppy (4-12 months)2.0
Senior dog1.0 - 1.2

Tips for Accurate Feeding

  • Use a measuring cup or kitchen scale for consistency
  • Split daily amount into 2 meals for adults, 3 for puppies
  • Monitor your dog's weight every 2-4 weeks and adjust accordingly
  • Treats should make up no more than 10% of daily calories
