Apollo is currently on Orijen the regular adult formula, and Patty & Molson are on TOTW Prarie formula.
I'm begining to think of switching Apollo though. He has pretty inconsistant poops. One day it'll be solid, the next loose. He eats 3.5/c per day and is 95lbs (solid muscle, NOT fat). He's very active; swimming, hiking, running, training, playing, etc. We also compete in dockdogs!
How does Natural Balance Active Dog formula stack up to Orijen? He liked NB and did well on, his poops were much better but he did eat slightly more, 4c per day.
