(1) I had a similar long trial-and-error process with my dog (2) Blue Buffalo has been growing extremely quickly over the past decade. The company went IPO in 2015 IIRC. I highly suspect the cost cutting on ingredients has already begun. (3) Blue Buffalo already sells lines which contain "grains and other irritants". I tried giving my dog "Wilderness" (the highest protein content with the least grain/filler) but it was too rich for him. For a while, I settled on a Blue Buffalo Life Protection which was cut with oatmeal, a grain.
