Flower, its interesting, but its not completely accurate. The "wild or semiwild dogs do not suffer from bloat" isn't entirely true. I personally have disgnosed a GDV (gastric dilitation with volvulus) in a wolf hybrid (supposedly 75% wolf) which was euthanized. I'm also aware of at least one anecdotal report in a grey wolf from the wolf sanctuary in St. Louis and an anecdotal report in a Maned Wolf. All of these animals were, to the best of my knowledge, fed whole food diets although the grey wolfs diet did contain commercial mazuri wild canid chow during certian times of the year.
I also have a bit of a hard time with the "low potassium causes intestinal dysfunction" becuase low potassium is generally associated with muscle weakness, cardiac arrthymias, and collapse first, then other effects. I'd expect to see to see a gait abnormality before there'd be abnormal intestinal motility becuase of the differences in smooth vs skeletal muscle.
I also had to smile at the cauliflower, barley, and rolled oats. Man, I bet you the dog fart smell would be nearly deadly in a house with dogs fed that.
Anyway, its an interesting thought.
