How much should I feed my dog?
The amount of food your dog needs depends on their weight, age, activity level, and the caloric density of their food. This calculator uses veterinary-standard formulas to determine your dog's daily caloric needs.
Understanding RER and MER
RER (Resting Energy Requirement) is the number of calories your dog needs at rest. It's calculated as:
RER = 70 × (body weight in kg)⁰·⁷⁵
MER (Maintenance Energy Requirement) is the RER multiplied by an activity factor to account for daily energy needs.
