Hi David –
Blue Buffalo does not report actual calcium levels on their packaging, they only report the guaranteed minimum. Basically, the minimum just means that the food is guaranteed to contain at least that much calcium – the actual amount in the food could be much higher. As far as I know (unless something has changed), Blue refuses to disclose the actual amount of calcium in their foods.
With that said, higher calcium levels are only of concern during growth. It’s perfectly fine to feed an adult dog foods that are higher in calcium.
