last week I started using Atlantic Pollock as the dogs' protein source. Charlie and Gwen get the NaturVet digestive enzymes while Dude gets ProPlan FortiFlora.. Charlie and Dude split an Extend packet while Gwen gets her own.. I use Veg-to-Bowl as their veggie source.. then this month is Best Buddy Bits in Cheese flavor. next time I'll use a different flavor. I stick with a protein source for awhile.. (last time, it was salmon) then they get canned food in between, before starting a new source of protein. I didn't supplement Dude with the Fortiflora for a few days - and it made a difference I definitely need to stay on track.
