They're both on the Rx food.
I'm going to switch them both to raw, but it won't be until this summer when I have the space to store the meat.
Thing is, I really don't know if it's the food, the immunotherapy or both that are keeping his allergies in check (somewhat). I'm a little nervous to change, but I have a feeling with Blue it's mostly environmental.
I really wish other companies made a hydrolyzed protein food. A company that used meat as opposed to soy as it's main protein.
I do believe that breaking the protein down so much, fools the body into not recognizing what it is, and in turn, avoids the allergic reaction.
So while I'm not a proponent of crappy foods, I can see how it helps with food allergies when nothing else works.
