Formula

Daily grams = dog weight (kg) × 1000 × activity factor (0.02 low, 0.025 moderate, 0.03 high). Per meal = daily ÷ 2. Protein = daily × 0.4. A 20 kg moderately active dog needs 500 g/day.

Worked example

A 20 kg moderately active dog. Click Calculate. Daily total = 20 × 1000 × 0.025 = 500 g; per meal = 250 g; protein share = 200 g. So each of the two daily meals is about 250 g with 100 g of chicken or meat.
