Dog Calorie Calculator
Calculate your dog's Resting Energy Requirement (RER) and Maintenance Energy Requirement (MER) based on weight, activity, and Body Condition Score (BCS).

Daily Caloric Target (MER)
Expert Tip
Most commercially sold dog food charts overestimate calorie requirements by 10-20%. Always feed based on your dog's Body Condition Score rather than cup recommendations on bags.
Calculation Methodology & Details
Formula
Resting Energy Requirement (RER) represents the baseline energy needed to sustain organ functions. Maintenance Energy Requirement (MER) adjusts the baseline based on activity, neuter status, growth, and body condition score (underweight pets get extra calories, while obese pets require restriction).

How to Compute Dog Calories: Step-by-Step
Determine daily calorie budgets with these steps:
Determine Weight in Kilograms
Obtain weight. Divide pounds by 2.2 to get weight in kg.
Calculate Resting Metabolic Base
Raise the weight in kg to the power of 0.75, then multiply by 70 to find the RER.
Apply Multipliers
Multiply by the lifestyle factor (e.g. 1.6 for neutered dogs) and adjust based on Body Condition Score (underweight, ideal, or overweight).
