Hi Molly,

If you are using Purina Smartblend Lamb and Rice, as Pitlove said, it is an All life Stages food. Purina reports the average nutrient analysis Ca content as 3.48 grams/1000kcals. I’d consider this level appropriate for an 8 month old large breed. I don’t see any need for you to switch off of it. As a bonus it has been through feeding trials
