Unsure how many grams of kibble your dog needs each day? Overfeeding leads to obesity and joint stress, while underfeeding causes malnutrition and energy loss.
Enter your dog’s weight, life stage, and kibble caloric density below to calculate their ideal daily portion based on veterinary energy standards.

🐶 The Science Behind the Formulas
1. RER (Resting Energy Requirement)
RER is the energy required by a healthy, resting dog in a thermo-neutral environment to sustain basic life functions.
- Standard Formula:
RER = 70 × (Weight in kg)^0.75
2. DER (Daily Energy Requirement)
DER factors in your dog’s current lifestyle, growth status, and neuter status on top of RER.
- Formula:
DER = RER × Life Stage Multiplier
3. Finding Kibble Caloric Density (kcal/100g)
Check the back of your dog food bag for metabolizable energy (ME). If it reads 3700 kcal/kg, that equals 370 kcal/100g.
