Have you tried the Nature’s Domain at Costco? You could try any of the flavors as they all have different protein and binders such as turkey and sweet potato. It’s best to rotate their diets occasionally to avoid them building an intolerance to an ingredient. I feed Victor’s Grain Free with beef and sweet potato which also might be a good option for you. There are many budget friendly foods listed on the editor’s choice list that might work or you. Just choose something that is not lamb and rice to see if it makes a difference. Good luck!
