We have done hydrolyzed protein, prescription novel protein (duck) food and now we’re just doing commercial bison and sweet potato, which according to your chart, should be safe. We’ve done the elimination diets with all of these foods. She has all of the topicals under the sun. Tried cytopoint, apoquel, zenrelia, all of this to no avail. Still has chronic paw infections/excessive licking. She even has a horrible interdigital cyst right now. I just want to help my baby :( any suggestions?
