It’s quite possible that he has an intolerance in an ingredient in the Keen. Keep in mind, it’s not just beef, chicken or grain to which dogs can be sensitive. It could be the chicken, grain, flax, cabbage, the soluble fiber, and so on. One of the things that my dog with food sensitivities cannot have at all is flax – it causes loose stool just like your dog has now. Just because your dog reacts to it, doesn’t mean it’s not a good product. Has there been a recent reformulation of the product? Figuring out food sensitivities takes a lot of trial and error. Strict elimination is the only way to do it. One ingredient at a time.
