Daily Energy Requirement (DER)
Expert Tip
Adjust calorie intake based on body condition. A dog with visible ribs needs more food, while a dog with no visible waist needs fewer calories.
Calculation Methodology & Details
Formula
The Resting Energy Requirement (RER) is the energy needed to perform basic life functions at rest. The Daily Energy Requirement (DER) scales RER to account for physical activity and metabolic state.

How to Calculate Dog Calories: Step-by-Step
Follow this method to find daily caloric targets:
Determine Weight in kg
Obtain weight. If in lbs, divide by 2.205.
Calculate Resting Energy (RER)
Raise the weight in kg to the power of 0.75, then multiply by 70: RER = 70 × (kg)^0.75.
Determine Activity Factor
Select factor: 1.2 for weight loss, 1.6 for neutered adult, 1.8 for intact, and 2-3 for active/working or growing pups.
