Calorie estimates are calculated using the Resting Energy Requirement formula (RER = 70 × weight_kg0.75) with life stage, activity, and body condition multipliers sourced from the Merck Veterinary Manual and the FEDIAF 2025 Nutritional Guidelines for Complete and Complementary Pet Food for Cats and Dogs. These figures are starting-point estimates — individual dogs vary, and actual needs may be 20–30% higher or lower. This tool does not constitute veterinary advice. If your dog is significantly underweight, overweight, or has any health condition, please speak to your vet before changing their diet.
This is your dog's current weight, not their ideal weight.
Daily walks, around 30–60 minutes
Typical range: 280–480 kcal/100g. Check the feeding guide on your food packaging for an accurate figure.

If your vet or food packaging suggests a different gram amount, adjust the calorie density slider above to match the figure on your food's label.
The daily calorie figure is calculated from your dog's Resting Energy Requirement — the minimum energy needed to sustain essential body functions at rest — then adjusted for life stage, activity, and body condition. A neutered adult dog at moderate activity needs roughly 1.6× their RER; a very active intact dog might need 2.5× or more. The gram figure converts that calorie target using the energy density of your chosen food type, which varies considerably between dry kibble, wet food, and raw diets. Always check the feeding guide on your food packaging, since calorie density varies by brand and recipe. These figures are estimates: monitor your dog's weight and body condition every few weeks and adjust portions if needed.
