Ooooo, pew-EEE

My guys never have gas at all. Gas usually means there is an ingredient present that is irritating their system, and likely making them very uncomfortable as well. Are you feeding multiple flavors of the medallions or just one? If multiple, then switch to just one and see what happens. If he has always had gas, then I'd also wonder if Innova EVO is the right food for him too...
Poor fella, I hope it gets better soon!
