Calcium and phosphorus figures need their units, basis and guarantee type to remain meaningful. A pair of percentages alone does not establish whether a food suits an individual dog.
What to check
| Check | What to verify |
|---|---|
| Measure | Distinguish percentages from grams per energy unit. |
| Qualifier | Preserve minimum, maximum or typical. |
| Context | Keep the nutritional adequacy statement beside the analysis. |

Distinguish percentages from grams per energy unit.
Preserve minimum, maximum or typical.
Keep the nutritional adequacy statement beside the analysis.
A practical example
A minimum calcium figure divided by a minimum phosphorus figure is not necessarily the food's actual calcium-to-phosphorus ratio.
Before you decide
Request comparable analytical data before attempting a precise ratio comparison.
