Hi Kim-

Your 2 year old Great Dane can be on any food you are interested in trying, but for your 1 year old Dane, he should still be on large breed puppy food.

You will need to contact Canidae regarding any formula you want to use for him, ask for the nutrient or typical analysis of that formula, take the values given for the calcium and phosphorus and input them into the calcium calculator found on this site and see if it meets the criteria for a LBP food.
