Hi Karyn-

I would recommend contacting Nature’s Variety and asking if one of their nutritionists can write you back. They offer dry,canned, raw, and freeze dried meal toppers. They are probably the only brand I would trust with a growing large breed. I’m sure they would be willing to answer some of your questions about your concerns with overfeeding too much calcium/phos. One of the nutritionists on their staff is renowed holistic veterinary nutritionist Dr. Susan Wynn.
