This is the only food my male dog can handle. I have had him on Kirkland's Super Premium Lamb and Rice and a few others, mostly the foods I have given were too rich for his tummy causing major gas and soft stools and worse. Authority Lamb & Rice has no fillers, no by products and no unidentified meat sources. The ingredients are tops using New Zealand Lamb. There is both Lamb and Lamb Meal in the top ingredients. This food is way superior to Nutro, IAMS, Eukanuba...etc Just take a look at the label yourself. My 3 dogs would agree.... Authority Lamb and Rice is awesome. Most importantly it contains no glutens, which has been the cause of the recent recalls.
