Sorry Crystal.. a little slow seeing this.. HONESTLY.. i just make the healthy powder and dont' give it another thought until every 6 motnhs she has a blood panal and then i'll know if she is getting what she needs.. something tells me those *wonderful* dog food manufactures dont' care that much about it.... maybe it's a myth like the protien thing??? i'm nto sure.. i'm going to go read about it and if i find anything out.. i'll be back
