Energy-normalized cost can supplement package pricing when reliable calorie figures are available. It still does not establish that different foods are interchangeable or suitable for your dog.
What to check
| Check | What to verify |
|---|---|
| Energy | Use the exact food's kcal/kg. |
| Quantity | Calculate total package calories. |
| Cost | Divide price by total kcal and multiply by 1,000. |
