Hi Molly-
Here is the good news. Purina ONE Lamb & Rice is an “All Life Stages” food, meaning it is for puppies as well as adults. So techincally she has been on a puppy food this whole time. However, I do not have the MAX calcium and phos for Purina ONE, so I couldn’t tell you if it was LBP safe. I think it would be wise though, to go ahead and put her back on a food that is known to be LBP safe (which Taste of the Wild Puppy is).
This is around the point of growth when they can begin to regulate calcium properly, but the current recommendation from veterinary nutritionists is to keep LBP’s on a LBP food until a year at the very least, 18 months is better.
