Dog Calorie Calculator
Estimate how many calories your dog needs each day using the same resting energy and maintenance energy method that veterinary nutritionists use. The tool first computes resting energy requirement as seventy times body weight in kilograms raised to the power of 0.75, which reflects how energy needs scale with size rather than linearly. It then multiplies that resting figure by a maintenance factor chosen for your dog situation, such as neutered adult, intact adult, weight loss, or active working dog, to give a daily maintenance energy requirement in calories. Enter weight in kilograms or pounds and pick the factor that best matches your dog. The result is a starting point for portioning food, not a prescription. Everything runs locally in your browser, and this is general information, not veterinary advice, so confirm with your vet for medical needs.

Frequently asked questions
What is RER and MER?
RER is resting energy requirement, the calories a dog burns at rest, calculated as 70 times body weight in kg to the power 0.75. MER is maintenance energy requirement, found by multiplying RER by an activity or life stage factor.
What activity factor should I choose?
Typical multipliers range from about 1.2 for a neutered inactive adult up to 2.0 or more for active or working dogs, with puppies using higher factors around 2 to 3. Pick the band that matches your dog daily activity.
Does it account for weight loss goals?
It calculates maintenance calories for the weight you enter. To help a dog lose weight, enter its target weight rather than current weight, and confirm the plan with your vet.
