His breath seems to have settled, or I might just have gotten used to it.
It was a new bag, but a brand he was on a year ago. I'm likely not going to finish the bag - it was just to test a theory (if food was related to his cyclycle diarhea). But he's itchy as can be. I'm going to have to decide between going back to Orijen or trying EVO (I considered TOTW but it's not sold anywhere around here)
