How much to feed per day
Estimated daily serving (g/day) based on the metabolizable energy of this food (3823 kcal/kg) and the maintenance energy requirement (MER) of an adult dog per FEDIAF 2024, from the lowest value (low-activity dog; neutered or indoor cat) to the moderate one (moderately active dog; active cat). It is a starting point: adjust to your pet's body condition and your veterinarian's advice. The calculation ignores age, neutering (in dogs) and individual clinical conditions.
| Weight of the dog | Energy requirement | Recommended serving |
|---|---|---|
| 5 kg | 318–368 kcal/day | 83–96 g/day |
| 10 kg | 534–619 kcal/day | 140–162 g/day |
| 20 kg | 898–1040 kcal/day | 235–272 g/day |
| 30 kg | 1218–1410 kcal/day | 319–369 g/day |
| 40 kg | 1511–1750 kcal/day | 395–458 g/day |
Formula: maintenance energy (kcal/day) = coefficient × weight(kg)^exponent. Dogs: coefficient 95 (low activity) to 110 (moderate activity), exponent 0.75 (FEDIAF 2024, Table VII-7, p. 55). Cats: coefficient 75 (neutered or indoor) to 100 (active), exponent 0.67 (FEDIAF 2024, Table VII-9, p. 57). Portion (g/day) = energy requirement ÷ (food kcal/kg ÷ 1000).
