What this means
A dog's daily calories start from its resting energy requirement — about 70 × weight(kg)^0.75 — then multiply by life stage. Neutered adults use ≈1.6×, intact adults 1.8×, growing puppies roughly 2×, and weight-loss plans 1.0×. At 20 kg that puts this dog near 1059 kcal a day, the target your food should supply.
Recommendations
- Weigh monthly — dog calories track weight, which shifts as the diet changes.
- Puppies need frequent, smaller meals and a growth-stage formula, not just more of the adult food.
- For weight loss have a vet set the plan; a sudden crash can be dangerous.
Watch out
- Multipliers are reference averages — metabolism, breed and climate cause real variation.
- Toy breeds have higher kcal-per-kg needs than giants, so size-adjusted is only a starting point.
