Dog Calorie Calculator — Daily Calories for Dogs & Cats
Estimate how many calories per day your pet needs, using the standard resting-energy formula and a life-stage factor. Use your pet's ideal weight when weight loss is needed.
How the calculation works
Resting energy requirement (RER) is estimated as 70 × (body weight in kg)0.75. The result is multiplied by a factor for life stage and lifestyle to estimate daily energy requirement. This is a starting point only — adjust with your vet based on body condition, activity and health.
