Frequently Asked Questions

How many calories does my dog need per day?
It varies widely. A 10kg moderately active dog needs about 500-600 calories, while a 30kg active dog might need 1500-1800. Use the calculator for personalized results.
Should I reduce calories for a neutered dog?
Yes, neutering reduces metabolic rate by 25-30%. Reduce calories accordingly to prevent weight gain.
How do activity levels affect calorie needs?
Sedentary dogs need baseline RER, moderately active need 1.5-2x RER, and working/sporting dogs may need 2-3x RER or more.
What's the best protein ratio for dogs?
Most dogs do well with 18-25% protein. Active and working dogs benefit from 25-30%. Puppies and nursing dogs need even higher protein levels.
Do large breed puppies need different calories?
Yes, large breed puppies should be fed for controlled growth to prevent joint problems. Don't overfeed to speed up growth.
