How the formula works
Resting Energy Requirement (RER) = 70 × (kg)0.75. We then multiply by a life-stage factor and an activity factor to estimate Maintenance Energy Requirement (MER). This matches the AAHA / WSAVA guidelines used in clinic.
Pregnancy, lactation, recovery from illness, and certain breeds need different multipliers. When in doubt, work with your vet.
