Feeding & Nutrition
Dog Calorie Calculator
Calculate how many calories your dog needs per day based on weight, life stage, and activity level using the veterinary RER formula.
Frequently Asked Questions
- What is RER and why does it matter?
- RER (Resting Energy Requirement) = 70 × weight(kg)⁰·⁷⁵. It's the minimum calories needed to sustain life at rest. Your dog's actual needs are RER × an activity/life-stage multiplier.
- How much should I feed my neutered adult dog?
- Neutered adult dogs need about 1.4× RER. An active intact dog needs up to 2× RER. Puppies and lactating dogs need the most — up to 2.5× RER.
- Should I feed based on current or ideal weight?
- If your dog is overweight, calculate calories using their target weight rather than current weight to avoid overfeeding.
