How It Works
This calculator multiplies the food weight in grams by the caloric density (kcal per 100g) to give you exact calories from meals, then adds calories from treats separately. The treat percentage shows you how big a portion of your dog's daily intake comes from extras.
Most dog owners underestimate treat calories by 50%. A single dental chew can contain 70-100 kcal. Factor these in consistently and you will have accurate daily calorie control.
Veterinary Research
Every formula is derived from peer-reviewed veterinary studies and clinical guidelines, not guesswork or generic rules.
