Use your dog’s weight, life stage, and activity to estimate a starting daily calorie target — then fine-tune with BCS.

Puppies vs Adults vs Seniors

Puppies 0–4 months ≈ 3× RER; 4 months to adult ≈ 2× RER. Seniors may need ~10–20% fewer calories.

Adjust for lifestyle

Working or highly active dogs need more; couch potatoes need less. Choose the closest activity in the calculator.

Track and adjust

Weigh weekly; change portions when BCS moves away from 3 (ideal).
