I recently switched my 15 month old golden retriever and my 11 month old Cavalier/Bichon mix to Blue Buffalo Sweet Potato and Fish. They seem to be doing well. Benny, my golden boy, has some sensitivities to some foods. He has IBS, and typically does not do well with chicken. Aside from loose stools, his eyes get pretty gunky. So far, so good on the Blue Buff. Does anybody else use this? What do you guys think of it?
